Hyperdimension Neptunia Explanation Page

==Introduction==
Unimaginative title aside, this is a page explaining how Neptunia's scaling works, and why characters are placed the way they are. Feats, statements, and otherwise logical conclusions will be used for justifications towards these placements.
This page is in coordination with the (at the time of writing) five canonical games:
*Hyperdimension Neptunia mk2 / Re;Birth 2
*Hyperdimension Neptunia Victory / Re;Birth 3
*Megadimension Neptunia VII
*Neptunia: Sisters VS Sisters
*And Neptunia: Game Maker R:Evolution.
In the event that new canonical games release after this latest revision of the scaling chain, it will be indexed once an English version is released.
The Scaling Chain will go from the weakest to strongest in order of top to bottom, with the weakest characters at the top of the page, and the strongest characters at the bottom of the page.
If you are confused as to why a character is placed in a certain spot, or why [X character] is excluded/included on the list, please message Kaio or Thetechmaster36 for more information.
With all that said, let's get started!

*Histoire | Does not attempt battling the Four Felons or entering the Gamindustri Graveyard in Re;Birth 2 whilst the Goddesses were captured, and resorts to sending IF and Compa in order to retrieve the also-captured NepgearHyperdimension Neptunia Re;Birth 2 (2014)Re;Birth 2 - Prologue. She doesn't join the party canonically to help defeat the Deity of Sin, even though she can be recruited into the party. She is noted to be "the world's everything"Hyperdimension Neptunia Re;Birth 3 (2014), helped stabilize the time-flow of two dimensions alongside her Ultra Dimension counterpartRe;Birth 3 - Chapter 10, and has an attack where she channels "the power of the universe" (Re;Birth 2-3) and/or "controls Nature and all existence itself to destroy the enemies" (Re;Birth 1). 
**Results in a Low 2-C rating and is the baseline for it since the Oracles are known to not be real fighter characters, as they never canonically participate in any battle.
**While Histoire can be added to your party in Re;Birth 2 via a special requirement, she does not join it canonically. That is to say, she does not appear in any of the cutscenes where the party is battling their way through the Gamindustri Graveyard in the final chapter, which is around the time when you would acquire her.
**Histoire is also a user of Share Energy, and although she has never been shown to use it in an offensive manner, she would still be Low 2-C because of it, as Share Energy acts as a power source; see this thread (specifically, the Heart Dimension stabilization feat in the "Tiering" section) for more information.
**This could also be "possibly 1-C" due to every single dimension in Neptunia possessing 9 coordinates in multidimensional space, with some of these coordinates extending through each other (as seen with Hyper Dimension and Heart Dimension)Megadimension Neptunia VII (2015)VII - Heart Dimension Neptunia H: Trilogy Finale: Into Legend. Since the coordinates are almost identical in the linked scene, this would make the sizes of the two dimensions non-insignificant - hinting that the dimensions are large 9-dimensional structures that have higher levels of infinity than the standard universal model. 
***Other unnamed dimensions during this scene, like Ultra Dimension or the implied "Producing Perfection" dimension (see the second link), would have similar structures due to Hyper DimensionRe;Birth 3 - Chapter 2 Ultra Dimension characters being able to perfectly visit and interact with them just fine.
*Killachine | A single Killachine was unfazed by the party's attacks, forcing them to retreat in Chapter 2 of Re;Birth 2, and multiple of them were able to fare against HDD Rom and RamRe;Birth 2 - Chapter 2.
*Warechu = Linda | Both of them have shown to get slowly and progressively stronger over the course of Re;Birth 2, even though they are easily defeated even by the end of the game. Although, they do grow strong enough to face the Goddesses and live to fight another day multiple times.
*CFW Judge | At the beginning of Re;Birth 2, IF, Compa, and Purple Sister couldn't defeat Judge, much less affect him. He is called the weakest of them all by CFW TrickRe;Birth 2 - Chapter 4. 
*CFW Trick ≥ CFW Brave | CFW Brave was initially able to defeat Uni, presumably in her HDD Form. He was later defeated by Nepgear and Uni, but still fared quite well. CFW Trick, while he didn't defeat anyone, had to be taken down by the whole party at the time + Rom and Ram in his battle, with 5pb. noting he was a tough opponent. And this happens just before Brave's fight, meaning it's possible that Trick is stronger than BraveRe;Birth 2 - Chapter 3.
*Copypaste | Had to be taken down by three HDD Goddesses. Copypaste regards himself as the strongest of the Seven Sages, although this is merely hyperbole given that this is only Chapter 2, some of the other Sages hadn't been fought yet (those other Sages are stronger than him anyways), and Copypaste is generally a very "loud and proud" character.
*Anonydeath | In his initial battle in Chapter 5, he needed to be taken down by four HDD Goddesses: Neptune, Plutia, Noire, and Nepgear, who had all grown stronger since Chapter 2, although Iris Heart notes how he went down so quicklyRe;Birth 3 - Chapter 5.
*Mr. Badd | His initial fight in Chapter 3 required him to be defeated by four HDD Goddesses: Neptune, Plutia, Noire, and Blanc. Blanc in particular was able to put pressure on the former three in a fight she engaged in prior, even though she was at lower Share levels than the three of them, so her being a part of this suggests Mr. Badd is inherently strongerRe;Birth 3 - Chapter 4. 
*Ultra DoS Arfoire | This form is only used once by Ultra Dimension Arfoire, and even then, she needed to be taken down by all of the Goddesses (at the time) in their HDD FormsRe;Birth 3 - Chapter 5.
*Ultra TDoS Arfoire | Stronger than her Deity of Sin form, surprise surprise, let's move on.
*Eggplant-amped Arfoire | After being amplified somehow by many, many eggplants, Arfoire forced a Chapter 9 Neptune to go HDD to defeat herRe;Birth 3 - Chapter 9.
*CFW Magic | Effortlessly stomped the HDD Goddesses and Nepgear at the beginning of Re;Birth 2. Later, in Chapter 5, she battled against the entire party at that point, which had fifteen members, eight of which are Goddesses, and the rest are Makers (although, the Goddesses all remained in their Base Forms for some reason)Re;Birth 2 - Chapter 5.
*DoS Form mk2 Arfoire | Even just a fraction of the Deity of Sin's essence was regarded as powerful, and in the Conquest and Holy Sword Routes, the characters were unableRe;Birth 2 - Chapter 6, Conquest Route to faze her according to 5pb.Re;Birth 2 - Chapter 6, Holy Sword Route, forcing them to use the swords in both routes.
**As of Sisters VS Sisters making the existence of alternate timelines canonical, as well as it canonizing the existence of Gehaburn, this is something which we can actually scale to the main timeline Deity of Sin. Normally, we would consider this invalid as a result of being non-canon, but SVS has proven that there exist alternate timelines, which would mean that these different routes exist in other timelines.
*Conquest Nepgear | With the power of Gehaburn, which had absorbed the souls and power of seven Goddesses at that point, Nepgear defeated the Incomplete Deity of Sin in one hit. Even though the Deity of Sin intentionally withheld from dodging, she stated, in her own words, that Gehaburn had the power to kill her.
**This does not result in a stomp rating for Conquest Nepgear. The idea that Gehaburn is so far above the Incomplete Deity of Sin is based on whether or not Gehaburn would have one-shot even if it fought back. That is a hypothetical; we don't know what the outcome would have been like if the Deity of Sin actually fought back, since we are never shown it. At most, we can guess that the Deity of Sin would have been defeated as per its own admission, but how much of a fight it could potentially put up is left to speculation.
**On top of this, Gehaburn's true strength is hypothetical as well, and has no basis besides the fact that it defeated the Deity of Sin in one hit, but even that has its own flaws.
**Nepgear being overall weaker in the Conquest Route than the other routes also lowers her rating a bit.
*Holy Sword Nepgear | Using the Share Blade, Nepgear was able to defeat the Deity of Sin, who fought back against Nepgear rather than letting herself get hit like in the Conquest Route.
**The fact that the Deity of Sin fought back against Nepgear alone puts this above Conquest Gear.
**Nepgear's strength was overall higher in this route, since she took on a resurrected CFW Magic with only four other characters (main four Goddesses) instead of fourteen others. Plus, the Deity of Sin was stronger in this route than Conquest Route due to statements made by the characters that she had been growing stronger, and the fact that she ended up reviving the Four Felons (something only seen again in the True Route, by the way) shows that the Deity of Sin overall has more power.
*BoS Human Form Goddesses / Candidates = BoS Makers | In Chapter 6, the party defeated the Incomplete Deity of SinRe;Birth 2 - Chapter 6. In Chapter 7, most of the characters all went out and defeated the Resurrected Four Felons: Uni defeats Brave (note how he says "Lowly CPU", as in, CPU singular), IF and Compa defeat Judge, Rom and Ram defeat Trick, and Nepgear and the main four Goddesses defeat MagicRe;Birth 2 - Chapter 7. They later all defeated the True Deity of Sin, said to possibly be the condensation of all of the Deity of Sin's absorbed powerRe;Birth 2 - Final Chapter. As per the fact that we see this form being used as a form above the Deity of Sin Form in future entries, the True Deity of Sin Form should be much stronger than its Incomplete Deity of Sin vessel.
**"BoS" refers to "Beginning of Series", which in this case, spans from the beginning of mk2 to the middle of Victory.
**Them being above both Conquest Gear and Holy Sword Gear is a result of the fact that both versions of Nepgear never got the chance to face off against the True Deity of Sin, whereas the main cast in the True Route did. The characters in the True Route are stronger than the characters in the Conquest and Holy Sword Routes due to the fact that they not only defeated the Incomplete Deity of Sin without the assistance of the swords, but also defeated the resurrected Four Felons, who should be stronger in this route than in the Holy Sword Route due to the Deity of Sin being more powerful (and the Four Felons being created from the Deity of Sin's power).
*Very Low-Below Average BoS HDD Forms | Obviously, because it's a transformation, it amps the Goddesses to a higher level of strength. The strength of an HDD Form is proportional to the amount of Shares it hasVII - HDD Form Nepedia Entry, and thus higher levels of Shares would mean higher levels of strength. 
*TDoS Form mk2 Arfoire ≥ Average-High Shares BoS HDD Forms | The HDD Forms at these Share levels are more powerful than the previous levels. The True Deity of Sin is obviously more powerful than the Incomplete Deity of Sin. However, in the fight with the True Deity of Sin, the Goddesses for some stupid, god-forsaken reason don't end up using their HDD Forms. At the point when you fight the True Deity of Sin, Gamindustri was essentially reclaimed by the Goddesses, and thus they would have the Shares of their nations back. But, because the HDD Forms were never used, it's unclear whether or not they would have a level of strength that is equal to, or slightly inferior to, the True Deity of Sin.
*Gamindustri-amped BoS Nepgear | After being strengthened by the wills and power of everyone in Gamindustri, Nepgear was able to slay the True Deity of Sin. 
*Fake Goddesses | Clones of the Goddesses made by Rei Kiseijou. Upon a Fake Purple Heart being defeated, the real Purple Heart states that if she had been alone, she would have likely lostRe;Birth 3 - Chapter 9. However, their strength also seems a little fluctuated, because Hyper Dimension White Heart and Green Heart were able to defeat at least fifty of them on their ownRe;Birth 3 - Chapter 10. Though, that could just be the possibility of the Hyper Dimension Goddesses being much stronger than Ultra Dimension Goddesses.
*Post-Victory Human Form Plutia and Peashy | By the end of Hyperdimension Neptunia Victory, Plutia and Peashy should be superior to the Fake Goddesses, as they slightly downscale from their HDD Forms, which partook in the 10-Goddess battle against Rei Kiseijou.
*Steamax | Steamax was able to take on a Low to Below-Average Shares Post-Zero Dimension Purple Heart, IF, and Compa simultaneously and sustain minor injuriesVII - Hyper Dimension Neptunia G: The Golden Leaders, Reconstructors of Gamindustri - Neptune's Story, although he appears to have been unable to injure any of the characters either.
*Warechu King | Put Steamax on edge and needed to be defeated by Purple Heart, B-Sha, IF, and Compa
*Rei's Powers in VII > Heart Dimension and Hyper Dimension Fusion = Baseline 2-C | The 2-C chain starts here. Now, let's explain this in lengthy detail.
**The core of the 2-C rating is here, involving Kurome's plan of Hyper Dimension and Heart Dimension together.
**For context behind this, after the party arrived in Zero Dimension to try and save the Goddesses, they convene with Uzume and Umio to discuss about what happened involving the Goddesses being kidnapped, to which Umio brings up some unnamed and unknown (as of then) phenomenon. Later on, some kind of quake happens that shakes the cast for a short while, prompting Uzume and Umio to inform Nepgear what has been happening. Uzume explains that, a little while after Neptune and Nepgear left Zero Dimension the first time, quakes started popping up all over Zero Dimension, and the dimensional coordinates of Zero Dimension were changing as a result. These coordinates are said to be absolute, and shouldn't change under any circumstances.
**As it turned out, Zero Dimension (actually Heart Dimension, as Heart and Zero Dimension are one and the same) was moving closer to Hyper Dimension's coordinates. When two dimension's coordinates overlap, they fuse together to form one single dimension. This, later on, was revealed to be Kurome's plan during a long monologue, meaning she was the one who was moving Heart Dimension closer to Hyper Dimension to fuse the two Dimensions, and the game makes it very clear that it was going to happen had Kurome not been stopped. In fact, such a thing had occurred in the Bad Ending of VII. Universal fusion is noted to be a valid justification for 2-C by the Tiering System, meaning that this can be used as a reasoning for the 2-C rating of this verse, and thanks to the existence of alternate timelines being canonized by Sisters VS Sisters, we can use the Bad Ending as valid justification for the feat itself.
**During this process, Kurome took Rei Kiseijou's powers off of Croire to speed up this process, with Croire noting that moving a dimension is a cinch with a fraction of Rei's powers. Rei's powers in VII are overall weaker than they are in Re;Birth 3 as well, due to a statement made by Nepgear following the second fight with Rei Kiseijou, and we've been shown that Rei's weakened powers have been overpowered by an Average Level of Shares in the first arc, meaning that the fraction of Rei's weakened power is slightly above Baseline 2-C as a result of the fusion acceleration. The characters also grow significantly stronger following the first use of Rei's powers in VII, which is the fight against Dark Purple-infused Arfoire, meaning that we can reasonably place the feat and Rei's powers this far down the chain.
*Trendfluencer | Trendfluencers are monsters that spawn from a Trendi Phenomenon, noted to be more unique than the usual monsters that come with said phenomenon, and Maho calls them strong as well. Blanc, coming out of the events of VII and having experience with facing Trendfluencers, tells the Candidates to stay on guard and to work as a team to defeat it. However, after it was defeated, Uni says that it was "nothing for us", suggesting it was very easy to take down, and later on, multiple Trendfluencers are defeated with ease or are even one-shottedNeptunia: Sisters VS Sisters (2022)Sisters VS Sisters - Chapter 1.
*1st-Amped Yellow Heart = 10x Normal Goddess Strength | Through the use of a remote energy injector, Yellow Heart's strength can be amplified to ten times a normal Goddess' strengthRe;Birth 3 - Chapter 7. After getting serious, she one-shot all of the HDD Goddesses up to that point, six of them in total, forcing them back into their Human Forms. Even when she wasn't serious, Purple Heart noted that she was a tough opponent, remaining seemingly unaffected by their combined effortsRe;Birth 3 - Chapter 6. 
*2nd-Amped Yellow Heart | After Peashy was taken away again, Anonydeath stated that he prepared a second energy transfer machine for Yellow Heart, and when encountered by the cast, Vert notes that Yellow Heart has more power than when they first met, which was in Chapter 6 when she had the first machineRe;Birth 3 - Chapter 8.
*Seely = Post-Victory Iris Heart and Yellow Heart
**Post-Victory Iris Heart and Yellow Heart | Partook in the battle against Hyper Dimension Rei Kiseijou, whom was near or at the peak of her power by the end of the game.
**Seely | Faces off against the Goddess Candidates and Vert in Chapter 2, although it was defeatedSisters VS Sisters - Chapter 2. It also went on to battle against F2P in Chapter 6Sisters VS Sisters - Chapter 6, who could previously battle against Gray Sister, and seemingly stagger her, in Chapter 4.
**Seely certainly doesn't have as many feats as Iris Heart and Yellow Heart do, but the fact that she could battle against five Post-VII Goddesses without sustaining major damage - only retreating after seeing the resistance put up - is enough to consider her equal to that of Iris Heart and Yellow Heart at the end of Victory, especially since the scaling after Victory becomes even crazier.
*Post-VII Gold Third = Post-VII Makers | All of these characters had been growing stronger over the course of the game through the many battles they had with each other and/or the Dark Goddesses. They were participants in the 8v1 battles against Dark WhiteVII - Heart Dimension Neptunia H: Trilogy Finale: Into Legend - Heart Dimension Route (Makers) and Dark BlackVII - Heart Dimension Neptunia H: Trilogy Finale: Into Legend - Hyper Dimension Route (Gold Third), and in the 16v1 battle against Dark Orange, making them roughly equal to each other.
*Copy Clique Trio | The Copy Clique Trio, though put together only have one showing which ended in their defeat, were still able to combat against the entire 12-member party, consisting of the First Makers, Second Sisters, and Victory crewNeptunia: Game Maker R:Evolution (2023)Game Maker R:Evolution - Chapter 7. Individually, Copy the Art unimpressively battled against the Second Sisters and Victory crew, only to be defeated moments laterGame Maker R:Evolution - Chapter 3; Copy the Hard shares a similar fate, battling against the Second Sisters and Victory crew before eventually losingGame Maker R:Evolution - Chapter 4; but Copy the Code does have an extra feat under her belt, where she is implied to have battled (and defeated + restrained) a member of the Gold Third before fighting the entire party and losing. Depending on the route chosen, it is either C-Sha or S-Sha that she restrains, but the character of choice doesn't necessarily matter since they're equal in strength regardlessGame Maker R:Evolution - Chapter 5.
*Current (Post-VII) Human Form Uzume ⇄ Base Zero Arfoire | Base Arfoire was casually putting Ultra Dimension Neptune on the run in spite of having been defeated by Ultra Neptune + two Goddesses in the first arc. However, it's possible that Human Form Uzume is more powerful, as she had fought numerous times against the Dark Goddesses before the game beganVII - Zero Dimension Neptunia Z: Twilight of the Desperate CPU, and also was a frontline fighter in the battles against Dark Green, Dark White, Dark Orange, and her internal resurrection battle against Kurome.
*Gold Form w/o Crystal | The very first fight they are introduced in is considered PIS - as the Goddesses were defeated by the Gold Forms at Average Shares in their first battle, yet later came back and defeated the Gold Forms with their Gold Crystals at presumably lower levels of Shares - and as such, we can't use that to scale them. We can simply upscale them from their standard base, and make them stronger than that as a result.
*Gold Form w/ Crystal = Zaikopath Clone
**Gold Form w/ Crystal | With the Gold Crystal, the Gold Form's power is boosted significantly, as the crystal gives the Gold Third access to their Golden Power. Some expressions of their power include Uni commenting that K-Sha, with her Golden Power, essentially has "God Mode" turned on at all timesVII - Hyper Dimension Neptunia G: The Golden Leaders, Reconstructors of Gamindustri - Noire's Story, and IF expressing doubt about dealing with a large amount of monsters without B-Sha's help.
**Zaikopath Clone | The clone(s) of Zaikopath's main body were able to overwhelm the Gold Third of Game Maker - though they were weakened and unable to transform - as well as heavily exhaust F-Sha after a battleGame Maker R:Evolution - Chapter 9.
*F-Sha | During the prologue, F-Sha receives praise from Ultra Neptune for being quite powerful, with the Failure Goddesses feeling the need to step in and help Neptune take care of F-ShaGame Maker R:Evolution - Prologue. In the Lastanita Route, she is seemingly the one to have knocked out the White SistersGame Maker R:Evolution - Chapter 3, Lastanita Route. In Chapter 6, she was able to combat against the Victory crew, whom were all in their transformed states, though she was defeated in the battle that followedGame Maker R:Evolution - Chapter 6. Lastly, in Chapter 9, she was able to hold off a clone of Zaikopath to buy more time for Lideo's device, though she left herself extremely exhausted in the endGame Maker R:Evolution - Chapter 9.
*Anri | Even though she said that she is not much of a fighter, Anri can at least somewhat hold her own against a Chapter 8 Human Form Nepgear, given how she was determined to continue fighting even after being defeated just seconds agoSisters VS Sisters - Chapter 8.
*Current (Post-VII) Orange Heart | Stronger than her Base Form, since the HDD Form is an amp of the Human Form, and she should be significantly stronger than the Gold Forms since even with their Gold Crystals, they were defeated by HDD Form Goddesses.
*Zero DoS Arfoire | This form is only ever seen one time in the story of VII, but in that same breath, it took two HDD Forms as well as an Ultra Dimension Neptune in order to take her down. On top of this, she is realistically more powerful than her Base Form.
*Affimojas | Affimojas feigned his defeat against the Goddesses and was able to catch them off-guard with an attack that injured and cancelled out a lot of their Shares, though he initially admitted that he had no chance against the Goddesses. The Goddesses, at this point, were at Average Shares due to Noire stating that the Goddesses have become more popular than the Gold Third, which would place their Shares at an Average level at leastVII - Hyper Dimension Neptunia G: The Golden Leaders, Reconstructors of Gamindustri.
*Shanghai Alice | Alice battled against Nepgear in Chapter 6, asking Nepgear to fight her seriously, to go all out, and that she wouldn't accept anything less than what was promised. Alice herself also went all out, though she still eventually lostSisters VS Sisters - Chapter 6. She has also been stated to be a participant in fighting off Trendi Phenomena for two years in the Candidates' absence.
*Higurashi | After going berserk, Higurashi posed a threat to Maho, who had previously one-shot a Trendfluencer and battled against Post-Chapter 4 HDD Candidates whilst she was having a headache. The crazed Higurashi needed to be taken down with the combined effort of seven Human Form GoddessesSisters VS Sisters - Chapter 7. Alongside Alice, she has been stated to fight off Trendi Phenomena for two years.
*Anri (F2P) | In Chapter 3, F2P battled against the HDD Candidates, as well as Black Heart and Green Heart, but eventually lostSisters VS Sisters - Chapter 3. In Chapter 4, they battled against Gray Sister, evenly matching her and even staggering her a bit, and Gray Sister said that she would give it her all against F2PSisters VS Sisters - Chapter 4. Lastly, in Chapter 6, they battled against Nepgear in the final battle of the Arena, and seemingly pressured Nepgear given her exhaustion at the end of the fightSisters VS Sisters - Chapter 6.
*Depowered Dark Purple-infused Arfoire | Heavily handicapped by the Sharing Field, which weakens Dark Goddesses by a considerable amount to where they can be harmed, despite Uzume not being able to lay even a scratch on Dark Purple initially.
*Zero TDoS Arfoire | Stronger than her DoS Form, and it took three HDD Form users and Ultra Dimension Neptune to take her down in the third arc of the story.
*Incomplete Dark Goddesses | Despite only having fought one incomplete Dark Goddess by itself in the story, the Incomplete Dark Goddesses (technically just Dark Purple) are implied to be above True DoS Arfoire if Arfoire needed to fuse with Dark Purple in order to try and defeat the cast in the final battle of the first arc.
*Ultra Dimension Rei | Contains a portion of the power that Hyper Dimension Rei holds, requiring her to be defeated by seven HDD Goddesses: Neptune, Noire, Blanc, Vert, Nepgear, Plutia, and Peashy. Rei's power is stated to have the power to distort and pierce dimensions, and like mentioned before, has the power to speed up dimensional fusion processes.
*This portion of power is also stronger than Rei's powers in VII due to not being weakened by the end of Re;Birth 3.
*Full Power Dark Purple-infused Arfoire | The fusion of Dark Purple and Arfoire on top of having Rei's powers after it was stolen from Croire. Unhindered by the Sharing Field, so she would be much stronger.
**The characters that participated in this fight (Purple Heart, Purple Sister, Orange Heart, and Ultra Dimension Neptune) all eventually grow stronger through numerous fights following this, such as through the Gold Third, Affimojas, and the other Dark Goddesses. 
*Main Body Zaikopath | During its past two incidents, Zaikopath was unable to be defeated by the Goddesses, and instead could only be sealed away after a long and hard fight. Additionally, it was able to incapacitate K-Sha on the first day of its third resurrection, and seemingly battled against the Gold Third to sap them of their strength. Vert goes on to say that the main body of Zaikopath exudes far greater pressure than its clones, and eventually battled against the entire party in their transformed states, though it was defeated afterward.
*Maho | Similarly to Anri, Maho is stated to not be much of a fighter. However, she has shown battle capabilities, as she could one-shot a Trendfluencer, and then eventually battle against the HDD Goddess Candidates, all whilst she was having a migraineSisters VS Sisters - Chapter 5. Amnesiac/Future Maho were also able to assist Future Nepgear in clearing out 200 Mech SoldiersSisters VS Sisters - Chapter 9.
*Gray Sister | As the HDD Form of Maho, Gray Sister is realistically stronger than her Human Form. She has done battle against the HDD Goddesses in Chapter 3, and also defeated the newly-resurrected Deity of Sin with the main four Goddesses in an alternate timeline after her first jumpSisters VS Sisters - Chapter 10. She fought evenly against the HDD Form Candidates in Chapter 4, and even knocked down / disoriented Purple Sister and Maho with an energy beam. Alongside the Human Form Candidates and Human Neptune, she (her Amnesiac self after unknowingly transforming) defeated Arfoire in Chapter 8.
*Complete Dark Goddesses | The Dark Goddesses were able to absorb the powers of the Goddesses, granting them more overall power, requiring them to be contained in a Sharing Field and defeated by a larger group of stronger characters since the fight against Dark Purple-infused Arfoire, which was the last Dark Goddess that any one of the characters fought.
*Base Kurome w/o Rei’s powers | Kurome is able to make as many Dark Goddesses as she wants so long as she has Negative Energy, implying that it takes very little Negative Energy to create a single Dark Goddess. Due to her massive supply of Negative Energy, which is noted to be decades worth of it stored up, she is above the Complete Dark Goddesses by a massive amount.
*Base Kurome w/ Rei’s powers | Although it might not be the greatest addition in power (since Rei's powers were able to be overpowered by an Average Level amount of Shares and had weakened since RB;3), it is still a boost in Kurome's power, and thus puts her above her Base Form without Rei's powers (even if she only used them to speed up the fusion of Heart Dimension and Hyper Dimension)VII - Heart Dimension Neptunia H: Trilogy Finale: Into Legend - Regrouping.
*Hyper Dimension Rei | Hyper Dimension Rei gave a portion of her power to Ultra Dimension Rei, and even called her "lame" and "weak" after she was defeated. Following the acquisition of more power from Ultra Rei's defeat, Hyper Rei stated she could destroy a world or two. She was on the verge of destroying the Ultra Dimension, even though this was simply a tactic to lure out the Goddesses over there, making this a very casual feat. Hyper Rei needed to be taken down by ten HDD Form users, and the fight had left them all tired out by the end.
**Hyper Rei is rated higher than Base Kurome in this case due to requiring ten HDD users at a much higher level of shares (minus Neptune and Nepgear since their shares had hit "rock bottom") to take her out, whilst Base Kurome only scales above the Complete Dark Goddesses - where a single one can be defeated by a lesser amount of comparable characters, including non-Goddess characters such as the Makers and Ultra Dimension Neptune.
*Full Power HDD Rei | The full power of Rei Kiseijou. Has the combined strength of both Hyper Dimension Rei and Ultra Dimension, making her even stronger than before, yet again requiring ten HDD Form users to be defeated.
*Current (Post-Game Maker) Base Ultra Neptune = Human Form Failure Goddesses | Coming off the heels of VII, Ultra Neptune and the Failure Goddesses were able to defeat F-Sha in the Prologue, though her wounds were healed off quickly. In Chapters 3, 4, and 5, they were able to defeat all three members of the Copy Clique Trio, with Neptune even shocking B-Sha with her strength; the latter saying that she (and by extension, the Failure Goddesses) were on the level of the Gold Third and GoddessesGame Maker R:Evolution - Chapter 5, C-Sha + B-Sha Route. Also in Chapter 4, the Victory crew was able to defeat fake copies of either Purple Heart and Green Heart, or Black Heart and White Heart depending on the route chosen. In Chapter 7, they had fought and defeated the four fake Gold Third members, all of whom were in their Gold Forms. Afterward, they defeated the Copy Clique Trio, even though their strength was restored right after due to having infinite lives in the game world. They then defeated the Trio again, supposedly "shredding them down to the tiniest scraps", according to BlancGame Maker R:Evolution - Chapter 7. Lastly, in Chapter 8, they fought and defeated ArfoireGame Maker R:Evolution - Chapter 8.
*Awakened Neptune = Goddess Form Failure Goddesses | Due to being in their transformed states, the Victory crew are all much stronger than their Base Form counterparts. In Chapter 1, the transformed Victory crew was able to fight and defeat Base Form C-Sha, though she was not taking the fight seriously whatsoeverGame Maker R:Evolution - Chapter 1. In Chapter 6, they were able to defeat F-Sha. In Chapter 9, the entire transformed party was able to defeat Zaikopath's main body. And lastly, in Chapter 10, they were able to defeat Zaiquone; a fusion between Zaikopath, Arfoire, Copy the Hard, and Copy the CodeGame Maker R:Evolution - Chapter 10.
*Zaiquone | As a fusion between Zaikopath, Arfoire, Copy the Hard, and Copy the Code, Zaiquone should be much stronger than its fusees, as it required the combined effort of the entire transformed party to be damaged enough for the Failure Goddesses to put it to sleep one more time. Additionally, during the climb to the top of Arfoire's company building, Uni states that Zaikopath was able to become much more powerful just from fusing with Arfoire alone.
*Current (Post-SVS) Human Form Goddesses + Candidates | Human Form Neptune and the Human Form Goddess Candidates defeated Arfoire in Chapter 8, whom previously needed to be defeated by seven HDD Form Goddesses. In Chapter 10, the eight Goddesses defeated Arfoire and put her vessel on the brink of death despite her getting stronger overtime from the IS CrystalSisters VS Sisters - Chapter 11.
*Resurrected Vessel Arfoire | After fusing with its alternate timeline self, the resurrected Deity of Sin gained more power, and afterwards, consolidated more power over the course of the game by absorbing the Infinite Share Crystal's Shares, growing stronger by the second when in possession of the crystal, and was even growing more powerful in the midst of battle. In Chapter 4, Arfoire battled against seven HDD Form users in its Resurrected Vessel, and even called the Goddesses a disappointment in Chapter 10. In Chapter 11, it needed to be defeated by eight HDD Form Goddesses. In the same chapter, Green Heart stated that the Deity of Sin is one of the greatest threats they've ever faced, which would include the likes of Rei Kiseijou and Kurome Ankokuboshi due to Sisters VS Sisters occurring after Victory and VII.
*Fake True Deity of Sin | In the final chapter, the fake copy of the True Deity of Sin form was able to battle against eight HDD Forms after they had already defeated Resurrected Vessel Arfoire at its peakSisters VS Sisters - Chapter 12.
*Arfoire-possessed Human Form Maho | Much more powerful than its fake True Deity of Sin clone due to simply being a fake copy. Whilst possessing Maho, the Deity of Sin was able to battle against the eight HDD Form Goddesses in Maho's Human Form, and seemingly sustained little to moderate damage, claiming that it was time for them to move on to "the main battle" afterward. It boasted that sealing it away would only delay the inevitability of the world's ruin.
*Arfoire-possessed Gray Sister with the IS Crystal's Shares | After removing the limiter on the IS Crystal, the amount of Shares absorbed from the crystal equated to an amount that had been accumulating for over two yearsSisters VS Sisters - Prologue, and was described by the Deity of Sin itself to be a "massive amount of Shares", forcefully transforming Maho into Gray Sister, and subsequently tearing her apart in the process. It required the full power of the HDD Form Goddesses to defeat it as Gray Sister, and even then, it was still able to stand up after the battle.
**To give a slightly more in-depth analysis and/or approximation on how large this amount of Shares actually was, the IS Crystal was continuously absorbing the Shares of the four nations for over two years. On top of this, the Magiphones were siphoning the Shares at the same time. The Goddesses were even concerned about whether or not Maho's body could sustain the amount of Share Energy planning on being absorbed, which was quickly to be shown to be too much for her, as the amount was brutally tearing Maho apart. Whether mentally or physically is never stated, but likely mentally, as something that very similarly happened to the Future Deity of Sin (losing sense of consciousness), whom had gained "unimaginable power" in the words of Future Gray Sister after the limiter failed on the IS Crystal in that timeline. This would, in turn, put Maho!Arfoire above the level of the Future Deity of Sin, and is highly likely to be way stronger given that the HDD Form becomes stronger as a result of more Share Energy.
*Current (Post-SVS) Low - Below-Average Shares HDD Forms | In Chapter 11, the HDD Form Goddesses were able to defeat Resurrected Vessel Arfoire at its peak, forcing the vessel to its limits and prompting Arfoire to abandon it. In Chapter 12, they defeated the Fake True Deity of Sin clone. After this, they went on to defeat Arfoire-possessed Maho, who even complemented them, saying they weren't doing so bad. And in the final battle, they defeated Arfoire-possessed Gray Sister - whom had absorbed the IS Crystal's Shares at this point - with their full power.
**As an explanation for why they are at Low to Below-Average Shares: In the build-up to this battle, we have seen numerous hints at the Goddess' Shares being extremely low as a result of the Magiphones stealing them away. There's a scene where Neptune states that her Shares are still low; a Trendi Phenomenon freezing event occurred in Lowee, over a vast range at that, which froze a majority of the citizens in space-time as seen through Nepgear's surprise at how little survivors there were (they're effectively dead due to this condition not being able to be reversed); the Trendi Phenomenon and its freezing events started popping up all over Gamindustri, and even froze towns with Trendi Phenomenon suppression devices installed, which were set up in every nation at that point; and lastly, a Lastation citizen comments that everyone in Lastation (besides those who survived) are frozen. All-in-all, the multitude of statements and implications point towards the Goddesses being at Low to Below-Average Shares, which the only possible exception applying to Planeptune. However, that is also indeterminable given that we are never given an idea as to if Planeptunian towns have had their citizens frozen or not, thus we assume it is simply at lower Share levels given the Magiphone circumstance and Neptune herself saying her Shares were low.
*Current (Post-SVS) Average - High Shares Main Four HDD Forms | As they possess more Share Energy, the Goddesses at these levels of Shares would be more powerful than their previous levels, as the HDD Form grows more powerful with more Share Energy.
*Depowered Dark Orange | A heavily nerfed version of Dark Orange who is weakened by both the Sharing Field and the Sealed Uzume's Share Crystal being drained of most of its Shares, which Uzume says would weaken Kurome. Inside the Sharing Field, it required the combined strength of 16 characters to defeat it; 9 HDD Form Goddesses, the Gold Third, Ultra Dimension Neptune, and IF + Compa.
*Full Power Dark Orange | The fusion between Kurome and the four Dark Goddesses that holds the power of the main four Goddesses, Kurome's own Negative Energy, and Rei Kiseijou's powers. This combined power was able to put the VII Next Form users in doubt about their victory. Kurome stated that a Sharing Field couldn't contain her power, and in order to stand a chance, Uzume had to drain the Share Energy from the sealed Uzume's Share Crystal, inherently weakening Kurome in the process, and then create the Sharing Field, effectively depowering her twice over, and yet she still needed to be taken down by a 16-member party, all of whom had grown more powerful from facing the Complete Dark Goddesses.
*Next Forms | The Next Forms, in their Nepedia description, are described to have a power that is more powerful than any HDD Form seen before itVII - Next Form Nepedia Entry, which would include a Full Power HDD Rei Kiseijou. This includes Gray Sister as well, as Gray Sister as an entity existed before the Next Forms were realized. The Next Forms, being a step above the HDD Form, should be significantly more powerful than that of the High Shares HDD Forms.
**Though not shown off in Sisters VS Sisters, the main four Goddesses should still be capable of accessing it, and as a result, would be much more powerful as a result of the main four Goddesses becoming stronger through the events of SVS. We can confidently say this, given:
***1. They were able to access the forms without the explicit use of the Hyper Share Crystal in two instances before this: once from an accidental side-effect of Uzume's Share Crystal, and another done completely on their own.
***2. Sisters VS Sisters canonically happening after the events of VII would mean that the Goddesses retain their ability to transform into their Next Forms, since this is not in an alternate dimension, timeline, simulation within the series itself, or in some random non-canon shenanigan place. As for why they didn't use the form? Could simply be summed up as Plot-Induced Stupidity or the developers temporarily forgetting that the form existed at some point in development. But even then. . .
***3. The Next Form weapons appear in Sisters VS Sisters as usable weapons by the main four Goddesses, meaning that it's not lost within the canon, nor did the developers seemingly forget its existence when creating the game, it simply isn't used in the game for some reason.
