Science

Gaster is quite a broken character. He managed to slice through an entire black hole with his bare hands in the first phase of his Overlord form.

1. W.D. Gaster: years: 620; LV: 40; HP: 60000; ATK: 5500; DEF: 5500;
2. Post-Dark Age: years: 1003; LV: 990; Hp: Unknown; Atk: Unknown; Def: Unknown;
3. Future Pre/post-Apocalipse: Age and Stats: Unknown.

* ~~W.D. Gaster during the war, with Gerson, was a strategic advisor to Asgore. After the humans sealed the monsters underground gaster become a royal scientist and created the CORE and echo flowers.~~
* Gaster is the strongest person in Undercore and the strongest version of Gaster that ever existed.
* Full name: Gaster, Wade,
* Family name: Wingding

"Even I can see the truth that you always reject" - Gaster to King Multiverse saying that he is just a puppet.

"You don't want to see me angry." - Gaster as he releases a portion of his magic.

"So this is the multiverse? This is truly interesting, so many worlds, with similar stories but with different outcomes."- Gaster's first time seeing a multiverse.

"IS THAT ALL?"- Gaster asked another version of him.

"Well this is interesting..." - Gaster the first time he saw the **Overwrite Button** while he observed the AU **XTale**

"Who the fuck did this to my son!?" - Gaster snarled at Grillby with anger after he heard that his son Sans was corrupted by **Demons.**

## Look

* Gaster wears black trousers, and a black coat (that looks like it's alive). Under the cloak, he wears a white sweater. His face has a crack and a hole in each hand.
* When he is angry you can see the vortex slowly coming out of his eyes and cracks.

## Personality

* His personality seems to have never changed.
* **Arc 1:**
	+ When he sets his mind to something, he doesn't give up under any circumstances. Gaster cares for/loves his family, even though he doesn't always show this.
	+ He doesn't care about stuff that doesn't consider him or his family and friends (in other words if something doesn't affect him or people that he cares about he doesn't care about it).
	+ Gaster doesn't like to talk much about his past.
* **Arc 2:**
	+ Gaster's personality didn't much change at all; until he started to slowly remember the resets. Thanks to his magic he stayed sane but was extremely afraid of the knowledge that there was a greater being that could change back time.
* **Arc 3:**
	+ During the Dark Ages Gaster became more serious.
	+ When Gaster learned what happened to Sans, he shows his emotions and by that, he shows his anger. Gaster was so angry that he stopped thinking normally.
* **Arc 4:**
	+ After becoming the ruler of the void he got a little of a god complex but thanks to his magic he suppressed that and act like he always does.

## Main Story:

### Before the Reboot

* About his past, we don't know very much but we know that during the war he was an adviser to Asgore and fought in many battles. Before the war, Gaster was a scientist, one of his experiments is the creation of Sans and Papyrus. (sans have 18 years when the dark age started). Later all that happened in arcs 1 and 2 happened to untie the reboot.

### **Reboot:**

* Gaster's story is going much the same way, but when the dark age begone Gaster becomes how to say it more active besides advising Asgore, Gaster with few other people the mainline defense from demons, During the whole dark age, Gaster like others was protecting the territory that demons didn't concerned and was going on the mission to beat the shit out of demons so he was dinged a great job. When Gaster heard that Sans got himself corrupted he becomes very mad, Gaster was so mad that he was looking for the demo that corrupted his son, Gaster was tracing any demon and tortures it until he gets his information. If not thanks to Julie, Gaster would alone go to the dark realm. After Gaster returns he got an order to go and attack one of the bases where the high demons are, Gaster agreed to go there because he was hoping that he will find that demon, When the attack at that bae become Gaster solo killed 800 demons with one move, and the battle began Gaster was killing a demon that stands in his way and so he finally has an encounter with one of the high demons, but unfortunate the high-demons doesn't care about Gaster revenge and so the high-demon has gone saying "Sans so that was his name such a weakling". Gaster is angry that he could not kill him but as a son, as he returns from the mission he got the news that princess Chara and Sans have returned. Gaster was heapy from the news and have a talk with his son after the talk Gaster confirmed that the light can help Chara after Sans and Chara moved out, Gaster with the others started preparing the forces for the battle, and so when Sans Chara returned, the preparation was finish and the forces have moved out. Gater with the forces was going to the gates of hell where Gaster has an encounter with one of the high demons it wasn't the same one that corrupted Sans but Gaster was heapy cause he could go overkill on that demon so, after a fight, all forces were right next to the gate but demons have closed, however, it didn't matter as so Gaster uses his void magic and go the dark realm killing demons that were on the other side and as he was fighting the Gates have been destroyed from the other side the united forces of humans and Monster enter the dark realm where the final battle has begone. Gaster with Jullie, Jenifer, river person, Asgore, Toriel, and the rest of the forces that cunted 1.8 thousand soldiers have to go to cancer one of the bastions, and after that, they go right to the castle where they were waiting for Sans, and Chara forces to join them, and so the final battle begone Gaster has Gaste with the other weer fighting the army of demons and the rest of the high demons when the other was going to kill the demon lord. Everything was going like it was with the plan but then the castle exploded and a demon lord emerged with his unimaginable power, Gaster was hoping that Sans is okay but then he realizes that he can't sense Sans or Chara, and so Gaster go pure rage and use all his magic and go one vs one against the demon lord, Gaster uses his magic and created a beast called hydra and fight him, during the fight Julie come to help him the same goes for all forces that are there, ad so Gaster with other fights him, The demons lord was getting almost no damage and then it happened a bright light has appeared and from the light Sans and Chara has come Gaster knew that it is the cause he senses their magic, and so Gaster uses hydra to hold it the demon lord when Sans and Chara give him the final blow, and so the demon lord was no more.
* After the dark age needed Gaster was one of the people that helped with rebuilding the cities and He was the one that paid for the ceremony that Sans and Chara have (he paid for the marriage of Sans and Chara). 4 years later Gaster was in the vid experimenting with his void magic in with the create overlord form when he achieves overlord form he also tries to confirm an old theory about the multiverse exists, and he tries it and find out that the multiverse exists. 2 years later Gaster with his son Sans, Alphys and many others help, they create the Core as a symbol that humans and monsters are in peace. 4 years later (10 years after we end, and Sans Chara's marriage) Gaster show Sans and Chara the doodle sphere (Multiverse), and so Sans and Chara, have some adventure and helping Gaster in some scientific stuff like helping him with gaining positive and negative apple from dream and nightmare. Gaster during the last 4 years before Eliash's arrival, has gained a lot of data, such as the x-event who is good who is bad, etc. and so Gaster with Sans and Chara has their little adventure and made sure that no one will find their au.

#### **After 14 years:**

* 14 years later after the end of the dark age, Gaster was relaxing/chilling at his family's house while his parents were on vacation, then the River person come to him and told him to go with him, Gaster agreed since he really doesn't have anything else to do and so he goes with him to the gates of hell when an encounter with a present that he never sees or felt before, River person introduce her to Gaster and they waited for the rest to arrive. After everyone has arrived they got an explanation, which Gaster wouldn't believe if not for the fact that he read about it since he was little, he knew what they are planning, and so Gaster says that he could help them locate the last part but they must go to his home town in his family house where there will be needed things to do it. Gaster tells the others that in his house he has one of the pieces that they needed, and so gaster with the river person and the new one goes back to the house of W.D. But when they arrived before they could go for it someone arrived that was holding the piece that Gaster was talking about all of them were on full guard since the one that comes was amazing so big mana that even without any ability you can sense, and so they go and fight him the fight wasn't fair because the enemy was using an advance time to magic and only river person thanks to his artifact could fight him, the battle was hard but Gaster was able to saw a small weak spot and used his magic and in result, the enemy wasn't killed but its retreat. As the enemy retreat, Gaster looks over the house and finds the book of Zegerid, and told River person and Anna the truth, so after the real explanation, Gaster helps them with finding the last piece. Book of Zegrid helps them find the way to enter the god's realm but they have to wait for the others after the other has returned Gaster told them what they must do, so they could go to the god's realm (haven) and find the last piece, but the one that attacks them has appeared and tried to destroy what they planing but thanks to new powers that they have awakened and with help of others they beat the shit out him and kill him, and so they finally use all 4 pieces and learn the what enemy is coming and they learn the origin of their world. After what they learned all of them start their preparation in secret from the rest of the world.
* 1 week after they defeated Eliash, Gaster needed to improve himself as well as his power, so he decided to go and travel between au's, meeting other versions of him, and he invited them all, to meet with him, which he convinces all the gasters to expect of "OG. Gaster and Abyss. Gaster" to arrive to the place where wanted want them (it took him a month to invite all his versions), and when they all arrived he reviled that he invited them all to decide which Gaster is the strongest. and so the place (void) where they arrive became a big battle royal where all Gasters from the multiverse have against each other, and Undercore Gaster have come victorious, defeating all the gaster, and he claims the title of the strongest Gaster in the multiverse. (**Battle-royal** took 5 years inside the void but in undercore, it was just 4 months)
* In the future (23 years after arc-4) Gaster got a big surprise, as Sans and Chara give birth to his little Granddaughter W.D. Sara. Yes, Gaster becomes a grandfather.

### Destruction of Geneiz:

* Gaster wasn't present when the sun suddenly imploded and destroyed the Geneiz, he learned about his home planet's destruction when he tried returning home after his space adventure, with Kitsune on a spacecraft known as SS-valencia. When he returned he only finds out that there is nothing but fragments of the planets and space dust, after realizing that his home was destroyed, he goes to heaven, to see if his son survives, and thankfully he did. After meeting with his son Gaster ask him if he has the power to bring Geneiz, but Sans simply said that he and Chara tied to prevent that but they were too late to do anything, as the energy hit the planet and after that, the Geneiz just was gone, not like it explode but gone like someone use Hakai on it and turned it into dust, Gaster coudnt belive that and ask if they were sme survivors and Sans says that yes there are survivors but are sent to difrent placed in the galaxie some were in haven or hell, and beside them there were no surviviors, Gaster just coundt belive what he learns, but Sans then says this "Altho Geneiz is gone now, it dosent mean that its gone forever", and that got Gaster couriius as then Sans explained that there was no soul from Geneiz that go to heaven or hell, as well that chara sensed that the time around the place that Geneiz suposed to be, is bent in many shaped, Sans explined that Geneiz might not be destroyed but traveling betwean timeline if not tuck in a moment somewere outside time but still within Undercore universe, Gaster was relieve that there still might be a chance for his home.
* After that Gaster was spending some time in heaven with Sans and other survivors helping here and there while the rest of his time he spend in the void researching some secret project. Eventually, 600-750 years later Gaster got news from Sans that planned Geneiz was found, and that Chara is bringing it back to their timeline, as the planet Geneiz was brought back Chara told them that currently, Geneiz is in a time-loop like a state, that it's still in tack but it also explodes with every nano-second, and that fixing that loop and ensuring that the planet won't explode won't be an easy task as any mistake could lead to triggering planet destruction.

### Meeting Alya:

* After many years, while Gaster was in the void researching a weird signature of energy that he recently found in some long abandoned parts of the void, he has encounter a person that like him has the power of the void, normally he would take a chance and talk with her, but he already had enough worries for an old guy as him, so didn't much want to talk with her, but she didn't leave and was beginning to annoy him for so long that he just give up and decide to become friends with her, and even shared their opinion on how the void operates, and work.

### Discovering the Necro-void:

* this is happening 2500 years void time (so like 2.5 years in Undercore time? It's hard to tell since time in the void dosent much exist) after they met.

* After Alya told him that this energy look like musical notes, Gaster was able to finally figure out how to find the source of that weird sifngarutre of energy, "if this energy is like musical notes then after changing it" - gaster as he change some data in the computer, the musical notes changed into numbers, they figured out that this energy is coordinated to a place within the void. Gaster decides to go there and ask Alya to stay as he wants someone to build their secret lab in the void from the unwanted eyes, as latently a lot of unwanted guests were entering his parts of the void, so Alya stayed while Gaster go where the coordinates were pointing out and so he finds himself in a weird place with 52 floating islands, then a voice from behind says "Ah Gaster finally. I see you decipher my message" Gaster turns around and says "Yes, and like it was in that message I didn't bring Alya which leads to one question why was I wasn't allowed to bring her?" In response, he said, "Now now, let's first enter my Necro-void and discuss there the issues, also please call Me Necros". After they entered the necro void they discourse why Alya wasn't allowed to come as well as what is the Necro void, what gaster learn was truly shocking as he wasn't expected the void to have such a location.
	+ The coordinates besides being the coordinates were also secret codes that after changing, it were saying "I welcome you to Necro-void, but if you have Alya with you don't bring her up, she is not ready to know".

##### What is the Necro-void?

* The necro-void is a location in the void that can't be found unless Necros wants someone to find it. A necro void is a place with 52 islands each one has one large glowing gold ball with smaller glowing balls floating around the big one, their look like **atoms** but on a Human size scale, and in the center there is one ginormous, moon size golden glowing orb.
	+ "You see this human size atom right? Well, those atoms are not just human size atoms but are comical verses of enormous size. You see the atom that we are right next to it, is the **Virtu-verse** from where you originate, the one in the middle is the tower of time that contains the virtu-verse including its omniversal time-splits, while those small balls around are the twilight realm, crimson kingdom, Descos realm, Null domniun etc. this "atom" is representing the entire Virtu verse, and is one of 52 verses that the 1str generation of the ancient ones created, see that one island of the opposite size from that location a creature called the Great one in the Anti-void defined the first champion of the void, but that a story for another day, oh before I forgot you see this giant golden ball in the center it is the Conceptual space, a place from where the 1st generation of the ancient ones originate, and before you ask yes the conceptual space is a Platonic space, making the 1st gen of the ancient a platonic creatures, those ancient are the ones that created your verse as their first creation, and later created all 51 other verse each one similar to yours but different both, in cosmology, scaling, tiering, everything actually." - Necros
	+ "This is a lot to take in, if what you saying is true then this is just truly shocking" Gaster was truly inspired by all that he find out about this, as well as truly in deep shock as this is just shocking.
	+ "Yea I know, it is shocking, after all, I was once one of the 1st ancient ones I with my student Tarn decide to join ourselves with the void, while he soon will pass, I am the platonic concept of Ignorance will remain, and wait for the right time to pass down the job to someone worthy" - Necros
	+ "I guess that you implying me but considering what you told me, especially since you witness this, you require more than just that am I right? So my second ques is that Alya is the one to take your place isn't it" - Gaster
	+ "Hahahahaa... You are really good Gaster yes, Alya is the one to take my position after she becomes the new champion of the void. But I have a question for you why didn't you ask if I not lying to you and you believe that those atoms truly are the verses that my race created" - Necros
	+ "Simple is the cause of life energy and magic that comes from this place, no matter how delusional, ignorant or stupid people might be, even they would realize that the energy coming from those islands are as real as I and you" - Gaster
	+ "I really made a good choice to invite you. Now Do you want any other answer to your questions?" - Necros
	+ "Only one Tell me about the anti void" - Gaster

* No this is not a joke the necros void truly contains 52 different verses, and even tho verses are just contained by one leave of one branch of the Yggdrasil.

### Gaster's fake death:

* At some moment in time in Undercore, Gaster has faked his death, as he said "I pretty much outlived most of the old friends, and family, and yet I don't feel to let myself die least not yet" - Gaster to River person while preparing to make a fake death.
* When the day of his supposed death has come, it wasn't much spectacular or impressive, Gaster simply "died" of old age, as he already was quite an old monster as not many monsters lived for such a long time. After Gaster well died, he went to the void, where he could continue his research on the void, while also no longer give attachment to undercore, as he knew that undercore is in good hands, he also found out about the parasite that Fresh Sans truly is, and send some rumors and news here and there to people that later on confirmed this, which resulted in a total extermination of the parasite, leading to **the parasite war**.

### The Apocalypse (destruction of core-verse):

* Not much is know what gaster was up to befre and during the apocalipse, he was seen in many places on many battlefields, holding the line betwean the forces of light verse and dark verse, but even he coudnt be everywhere, and they were many desroyed multiverses, and lose of important strategic points, but nothing hits harder when he Core-verse a multiverse from where he originate sudendly teleported its location in the ceter of the war, and Sudendly it has Inploded causing a large explosion, that destroyed countless multiverses, and cause a extreme form of unconrtoled chaotic force to be relised that destroyed even more countless multiverses.
* After the core-verse was destroyed Gaster was just... He lost everything that ever was related to him, but even so River person and few that like him joined this war, told Gaster that altho undercore and its multiverse is gone, there are still are people that will remember the core-verse, and the sacryfice that was made, as that explosion cause such damage for both side, that it eventualy resulted in a temporary "buring the axe of war" as well several milions years later the last of the counters was defeted, and the apocalipse has ended, and the light verse and dark-verse was recreated into the new virtue verse.

### Post Apocalypse:

* After the apocalypse, Gaster spends a lot of time with Necros, looking where his son and Chara go, by scanning the entire void, in hopes of finding any new location, or a sign of their energy.
	+ During this time gaster learns a lot more about the void, and even created and new V3 of the Overlord form, notably buffing the abilities that he already had in his v2 but also achieving 2 new powers that he doesn't like to show up.
* At some time, he suddenly felt a large amount of void magic dropping down from him, and right after, the entire necro void suddenly shook "how can a void shake?" - Gaster; "Less care about the void better help in sustaining the verse's as they might collapse by that large energy that suddenly came from all directions" - Necros; After keeping and the verses together and protecting them from that extrocerestial energy, gaster decides to use the machine that he created with the help of Necros to track the source of that energy as well in case if that energy again strike, they might be alarmed much ariel before the energy will shake the verse to their near collapsing.
* Later on, Alya came to them asking if they know something about that energy, in which Gaster responds that he was tracking down that energy, and after the machine find the corodinate to the source of that energy, Gaster with Alya go there while Necros stay behind and prepred a shield around all 52 verses in cahse that energy strike again. And as Gaster and Alya arive where the source of the enrgy, they discovered the tri-void. They got encountered one of the inhabitants of the Tri-void, that let them into the city, and told them about the grand war, and the Triberus Ventigor, as well as to how he recently came back from non-existing. After hearing that Alya and Gaster wanted to meet with him but unfortunately for them, they didn't allow them, as Triberus says that anyone from outside the tri-void came they must be stopped from interfering with his plan on regaining the power that he once wields. This resulted in both Alya and Gaster fighting against a horde of tri-void soldiers, and Gaster told her to stop Triberus while he deal with them, and altho Alya didn't waned she go to stop him, while Gaster stayed behind and decide to use them as a good test drive of V3 of the Overlord in a real battlefield, and so Gaster has fought against a number of enemies equal to 10 Septyllion soldiers (1 septillion is 1042), while he was holding them of Alya finaly reach the Triberus chamber and fought him, whith resulted in relesing such tremendus and uncotroled power, that everything was shaking, and if not for Necros shield the 52 Verses and the Primodiald realm (a Platoninc place) would colapse and turn into non-existence, and even tho they fight, Gaster still was figthing againts the amry as he nedded to hold them off from interfiring in that fight. After alya defeted Triberus, and Gaster preaty much hold the entire army all by himself, as he didnt waned to sumoned his void creatures, as he wouldnt be able to recongnice enmy from ally plus he was not sure what his void creature would do when he summon/create them, the tri-void was in tottals ruins and the inhabitants sorender but they werent much sure what to do with them as they coudnt risk that they take revenge and so Gaster got an idea of becoming the void ruler of the Tri-void, Alya wasnt sure but Gaster confinve her, and so Gaster become the Void ruler of the Tri-void, gaining acess to all their knowldge and weaponly.

## Power/abilities:

### Soul magic:

* Kitsune help him and taught him how to use soul magic, but unlike Kitsune, Gaster has never mastered this power. "Even tho you know how to use those powers you are simply not fit to use their full potential, not even the "god of magic" could do it. So here is my advice, just remember what you can do with those powers and nothing more, because if you continue this, you may shatter your soul" - Kitsune to Gaster, after intense training

* **Soul of patience:** That power makes Gaster more patient thanks to what he can see that he wouldn't be able to see normally (thanks to that soul he didn't fall to the core). Also, the patience-soul magic allows him to check someone's memory but he can do that only when a person is not awake or if that person is alone to do it.
* **Soul of kindness:** That power allows him to faster heal himself and it also heals any ally that is in a range of 5-8 meters.
* **Soul of bravery:** That power makes Gaster and everyone that is in the 10-14 meters range, very brave, the 20% of their stamina is restored.
* **Soul of integrity:** When Gaster uses that soul, no one that is under the light can lie (it is very good for interrogation).
* **Soul of Perseverance:** perseverance not only stops dropping stamina but also allows him to use powerful attacks even if Gaster doesn't have enough mana.
* **Soul of Justice:** Gaster using justice's soul allows him to see through lies and illusions, also it helps to tell when someone has guilt on his shoulders.
* **Soul of Determination:** Gaster can't do the same thing as Chara does with her soul magick, but it allows Gaster to temporarily have determination thanks to his attack and defense being double. But that works only for 5-8 minutes.
* **Soul of Hate:** When Gaster uses that soul, He goes berserk, and his attack and magic power are doubled 10 times, but he can't tell the difference between friend and enemy (he uses that as last resort). The effect of this ability last from 15-20 minutes.

### Blasters:

* Gaster blasters are much bigger than sans blasters and similar to sans blasters, his blaster also can fuse magic. However, his blaster can be fused with void magic only when he is in his overlord transformation.

##### Special attack:

* Gaster's right hand glows blue, and his left hand glows orange, after that gaster's power is multiplied by ten thousand. From his eyes is coming black liquid (void), and the gaster cloak is starting to move like something big is about to show. When the gaster uses that attack first a barrage of blue and orange lasers comes out, then his cloak looks like it is made of water and then three blasters come out, one blaster with blue eyes from the right and ta hen blaster with orange eyes from the left, and in the middle blaster 2time bigger with purple eyes (Gaster then look like he is melting).

### bone magic:

* normal, blue, and orange attacks. Gaster only uses sharp bones. He can use bones as a shield, or walls to protect allies from enemy attacks.

### Experience:

* During his entire life, in his hometown, in a pentagram, and during the wars, Gaster learned many things, and gain a lot of battle experience, he is very good, at predicting his enemy's movement, as well he is fast to adapt to his enemy, as he shows a fight against Elaish Gaster quickie adapt to the fighting style of Eliash.
* As well he shows very high experience in direct action of an army, thanks to which he gained the trust of Asgore and becomes his advisor in war ("It gives really good benefits to me and my family. Having the trust of the king on our side is a very good thing, we can now do more than normal" - Gaster thought).

### Magic link:

* It is an ability that gaster learned during the dark age that ability allows him to make along with magic, it allows him to track other people or sense when they are underage. After Sans returned Gaster secretly put magic ling on "Sans, Chara, Papyrus, Jull, Muffet, and Grillby as also at Jeni, Doggo, and ~~Kitsune~~". (Kitsune finds out that he put this in her and she removed it). Gaster uses this ability to have a tracer, he can put a small gram of his magic on the person and can sense what that person is dead, he also can find the location of that person in that he put a tracer.
* Yes, gaster can see and tell the difference cause every people that he market has his sense of **Magic**.
* Magic links have also a secondary ability. The second ability of magic ling is to transfer mana, in simple words Gaster can give someone mana to recover, and vice versa (but the person must agree first). The magic link was used by the Funders during their fight against him.
* **Fun fact:** Anyone can use and learn magic links, it is a natural ability that everyone possesses but is not used very often.

### Crime Manipulation:

* During his time as a member of the **pentagram**, Gaster learned and did a lot of schemes and manipulations, in which he now shapes and manipulates all types of crimes, during his time in the pentagram he planned 36-40% of all crimes committed during and even 20 years after the fall of the pentagram the crimes that he played were committed in Okami island.
* Currently, it is unknown if he still manipulates crime or not, but there are rumors in the criminal underground that there is a person that hears, sees, and plans every crime. It might be Gaster or Kitsune or even someone new that entered the ring, a new challenger.

### Void magic:

* It is gaster's original magic that allows him to create a portal to the void (he can open a portal as big as he wants) where he can do more dangerous experiments (never fight him when you are inside his void). He can open a portal to almost all places like save scream and block the buttons that the player uses. the only places that he can enter are the Abyss and Shadow-world.
* This magic allows him to manipulate the void (He controls the void).
* Void magic does not waste any stamina or mana, as void magic works differently than normal magic.

#### void creations:

* Gaster can use the void to create weapons, walls, and all tentacles that he uses to grab his enemies. Only his imagination is his limitation in using this magic.
* He can also use void as a weapon for example a technique called death zone (enemies are surrounded by void and then are attacked from every side).
* He can also use this magic to make weapons like spears, shields, claws, etc.
* He used this ability to create his cloak, which he normally wears, as well as to create a throne inside the void as the symbol that he is the one that controls the void.

#### Special attack (full name: Void creation magic Hydra):

* Gaster unleashes the full power of the void creation and he for a monster called hydra it's a big black dragon with seven heads on the top of the middle head Gaster is standing, the hydra is so big and powerful that can hurt even guys with infinite defense (it's not giving those guys of infinite def any damage but can make that you feel pain like you got 99999999999999999999999999 damage).

#### Void army:

* Gaster is capable of creating soldiers made of the void
* Gaster was able to create 4 void beings during the 2nd arc of the experiment. After he gained a high lv and a lot of experience during the 3arc Gaster gained better control over his void magic, as well he can create many more void soldiers (he can create 12thousynd soldiers).

#### Void sword:

* The void sword is a weapon that he created, for a simple purpose. To kill unkillable enemies means that the void sword is the only weapon capable of killing characters that are immortal example fresh sans, or a version of Gaster's that fell into the core and was scattered between time and space.

## Weaknesses:

* **Anti-void:** The void magic can't work inside the anti-void. Besides that void magic can be used anywhere.
* **Other weaknesses:** Unknow. Gaster has always his guard up.

## Transformation:

### Overlord:

* Gaster was bored and wanted to do something exciting but nothing interesting was happening, so during his free time, he started experimenting with his real special attack to know where is the limit of that attack during this experiment Gaster figured out that whenever he uses his real special attack his connection with the void is getting stronger and that gives him a perfect Idea. After 4 years of experimenting, Gaster finally found a way how to fuse with his real special attack, the result was spectacular he got a new look and his connection with the void was 800000 times stronger than ever. The first time he uses that transformation was in arc 4 the coming terror when he was fighting with a very strong creature.

#### **ver.1:**

* Gaster in that form looks like he wears dark armor with blasters on his shoulders knees and back. In that form, Gaster's connection to the void is stronger and he can do whatever he wants with his or any other void (in other words Gaster's power in control of the void can rival even with **The Void Empress**. But who knows is true or not). Also in Overlord form, Gaster blasters are given with new ability called **"void banish"** that ability allows gaster blaster blasters' energy out of the void, and when the target is hit, it is banished to the random void and vice versa (you can't dodge the attack because it's locked on you). Void Banish can send a living person, part of a building that took the hit, or even a laser beam that clashes with void banish, outside any void or overworld. Even if you make a shield of magic, the dark-purple beam of void banish will send the part of the shield that takes the hit to the void and vice versa. In other words, only the ability of the void, anti-void, or mainframe, can stop the energy beam that the void banish is sending. Of course, this form wasn't complete at first when Gaster first used it so, he was working to master it. His mastered/completed version of the overworld was more powerful in defense and attack, After he mastered this form, he also gained quite a power boost to his speed and defense, thanks to what, Gaster even without using his magic to make a shield the armor will protect him.

#### **Ver.2:**

* After the experience of **arc-4** Gaster realizes that his overlord form still needs to be improved, so he goes around the multiverse inventing other versions of himself, and as he was doing that he also watched some other aus and saw what is lacking in his overlord form. Gaster before the battle-royal started upgrading his armor by changing the look, the look didn't much change however the upgrade of his form made his armor lighter, more flexible, and much more durable.
* The up doesn't stop there, he changed his look to be more suitable. During his quest of inviting other gasters, he saw something interesting and was inspired by it which he create two new abilities: "**Void shield**" (inspired while seeing GT.Gaster) and "**Void cancel**" (Inspired by Gaster from Unknow au)

##### Powers:

* **Void banish:**
	+ Gaster blasters in overlord form are fused with the energy of the void, and that gaster blaster can send a bean of void energy and send the target to a random part of the void or overworld.
	+ After 30 years he advanced this ability, thanks to which he can use void banish by touching a ponent and then wasting blasters, the disatwantech is that it must be physical touch.
* **Flying:**
	+ In this form, Gaster is capable of flying. At first, he needed to create wings or use his blaster that is attached to the armor, but 15 years later, he figured out how to use the void armor to fly with any help. With this ability, he can move at a speed of Mach 0.65 (so he moves nearly as fast as **Asriel**, the difference is in 0.08 Mach, so Israel moves at a speed of Mach 0.73).
* **High-speed:**
	+ Thea's blaster is on his armor for a reason, Gaster can use this same blast to raise his speed-movement and the speed of his physical attack. He can use the blaster as a power bust to make a punch much faster and harder or use his blaster to increase speed movement and increase his speed to dodge attacks that move with the speed of light.
	+ When he combines his hight-speed with his flying ability, he can break the sound barrier 40 times over, within 4 minutes.
* **Extreme-defense:**
	+ In his overworld form, he wears armor made of the void so his defense from close combat is bigger, most of the physical and magical attacks are absorbed by the armor. The armor can block most of the attack, and there is a 1/60000 chance that the attack will be effective, but even so, the damage will be minimized, or even there will be no damage at all, for example, if he was punched by Jenifer, the force of the attack would be absorbed, but gaster would still be pushed 4-6 meters away, but with zero damage taken.
* **Void shield:**
	+ This ability was created after Gaster was experimenting with shield and void magic, he combined both magic with resulted in a void shield. The void shield is a dark purple energy shield that not only blocks any physical attack but also if someone will touch this shield directly it will get 200-350 damage. The downside is that it doesn't block the magical attack but considering the defense that his armor gives, it is a surprise that has even diced to learn such an ability, but again if he needs to he can use it to protect his allies.
* **Void cancel:**
	+ Void cancel is an ability that Gaster created after meeting with Gaster from the unknown au where his Sans can cancel other abilities (including plater reset and save button). Gaster was inspired by that and created a similar ability but it does not work on an attack by the void abilities. In simple words Gaster can use this abiluseto cancel an enemy's void abilities, for example, cancels someone's ability to control the void, however, this ability effect is active for a 35-minutes, and to use it again Gaster must wait for a 1-hour. While creating this ability Gaster trained hard to master it this ability in a way that he won't be affected by this ability, as at first this ability also canceled his void magic.
* **Immune to reality manipulation:**
	+ This is not an ability but more of a nature of this form. As the void was before, the reality was a thing, the armor made full of the void, negates the effect of the reality manipulation, in which Gaster, is not affected by a reality-warping ability, this can be applied to his cloak that is made of the void, but in a smaller scale, as the cloak, unlike the armor, is not attached to the whole body.
	+ He is not only immune to reality waring but to any kind of warping such as law or casualty manipulations, but he has not yet discovered that, as he still did not reach this level of void control to be immune to law or causality manipulations (it might take him thousands of years).

#### V3 (final version)

* The third version of this form was created and made with the help of Necros after the apocalypse ended, but we're working on it while the apocalypse was still going on. This form is the final version of the overlord.
* **Look:** Not much changed from the 2nd version, but it become much more durable, endurable, and powerful.

##### Powers:

* Besides the abilities that he already had before, this version is buffing the previous abilities and gives gaster 2 new powers.
* **Two new powers:**
	+ **Void** **Conceptual Mode**: Whenever Gaster activates the third version of the overlord, he became a being that is granted power over the concept of the void, becoming in a way an **embodiment of the void**. He is not on the same level as Alya but he is one of the closes to her level.
	+ **Void flames:** Gaster to a small extent can create the flames of the void, he cant generate them, but thanks to his blaster he can shoot the purple fire that is the flame of the void.
