Big Fat Ugly Bug Faced Baby Eating O'Brien

"I AM BIG FAT UGLY BUG FACED BABY EATING O'BRIEN!"~ O'Brien introducing himself in Almighty Tallest Danny's 2016 Birthday Special (PART 1).Big Fat Ugly Bug Faced Baby Eating O'Brien is the strongest member of the Rhaatror species & is a main character in the Terrachaovese series. He is well renowned as a champion warrior on his home planet, & has built a high reputation within the ranks of the Monirken Empire. 
Tier: 6-B
== Appearance ==
O'Brien appears as a very large alien monster with silver skin & rainbow stripes, although the stripes appear more prominently in his shielding mode, which is when his body shifts to look bulkier & his mouth is visible. He has two dark gray arms with 4 fingers each. His eye casts off the illusion that it's invisible because his eyelids are like mirrors, only they somehow cast the reflection of what's behind him. He also has an orifice that fires energy beams & projectiles, but can only reveal it when he enters shielding mode. His lower half is comprised of a blue, fish-like tail with shining scales. O'Brien is fully capable of walking on land, however, & does so in a similar fashion to Zigra from the Gamera series.
== History ==
=== Champion of Rhylota ===
O'Brien was born on planet Rhylota many years ago, but it's unknown as to how old he really is. According to the amount of words within his name, he is part of the 8th generation of his family lineage, as Rhaatrors add a word to the names of each passing generation.
The Rhaatrors are known for their hatred of Tubians; a natural rivalry that's persisted throughout their species' entire history. O'Brien once challenged their leader, King Tubias in a battle for supremacy. If O'Brien won, the Rhaatrors would become the dominant species of the planet, & if he lost, the Tubians would take over. Unfortunately, O'Brien lost the match & the Tubians proliferated out of control. But the Rhaatrors didn't shun O'Brien for his defeat, rather they admired his bravery & motivated him to get stronger so he could partake in a rematch. Ever since that day, O'Brien trained his hardest to become the strongest there ever was, which would pay off in his adulthood. O'Brien challenged Tubias once more years later, & this time he actually won, completely overwhelming his archenemy. Henceforth, the Rhaatrors praised O'Brien as the strongest member of their kind to have ever lived.
=== Imperial Initiation ===
In the August of 2013, the Irken Empire had come to add Rhylota to their vast collection of worlds. Despite the negative reputation that the warmongering Irkens have built over millennia, the current Almighty Tallest were much more benevolent in comparison. Rhylota had been an interest of theirs for quite some time, & one of their second in command, Princess Celestia had made a diplomatic accordance with the Rhaatrors, allowing them to consider their planet Irken property. Since then, the planet has been kept as a nature reserve, as its flora & fauna are rare & must be kept safe from other invasive species. O'Brien himself, while not the leader of the Rhaatrors, certainly played a big part in this coming to fruition. Almighty Tallest Daniel Ledda was particularly impressed by O'Brien's power & would come to befriend him as time went on, allowing him to visit his home planet Earth whenever he wanted to. This would be very beneficial to O'Brien, as the one thing he didn't like about his home world was that the swamps were usually quite dirty.
Also, on one day during that month, O'Brien had somehow contracted the blue flu after coming to Earth, where he had to stay in Dan's pool for a long time for it to go away. Here is where he met the infamous Babyman, along with some non-Irken people who served Dan's new empire.
=== Founding Super Battle Bros. ===
At another point during summer 2013, O'Brien partook in a battle in the pool where he went up against Dan, Jake Fall, & Owen Fall. It was a long fight, & they mostly did this just for sparring, but the Kaisers would emerge victorious in the end. This battle would become the prototype for something big that the Kaisers would finalize in the future.
In 2015, O'Brien had started to visit Earth much more frequently, & would sometimes stay for long periods of time, making an agreement with Dan that would allow him to live at his house during summertime. Also during this year is when O'Brien became acquainted with Lord Claudius Ko'Al.
=== Protector of the Pool ===
In the July of 2016, Dan, Jake, Owen, & O'Brien founded a competitive fighting tournament called Super Battle Bros, where being from all across the Multiverse can take part in & combat each other for whatever reason they desire. On the 18th this month was when Fallaballa got the blue flu, & Kyle Ron told him to go in Dan's pool as part of the healing process, where a special medicine would dissolve in the water for him to absorb. O'Brien was present but kinda just watched as the events unfolded. Unfortunately, the medicine didn't work & Falla was in a near-dead state for ten days, though O'Brien thought he was actually deceased. On Dan's birthday four days later, O'Brien teamed up with Hydrion Barfallonyou, Toy-Toy Ninja Man, Jack Jarren, & Biggus Dickus VII to eliminate a rogue Tubian who had somehow infiltrated the pool without the empire's consent. The Tubian had put a good fight given his odds, but O'Brien was the one to finish him off, vaporizing him with a Plasma Grenade. 
On September 5th, O'Brien was relaxing in Dan's pool, watching as Claudius had made an encounter with the last living Yidrovian, Archaios. They briefly chatted, & before Claudius was ready to leave, O'Brien told him that he had received a letter; a postcard from his parents, saying that they miss him. Claudius said nothing, twirling his cape & solemnly went in the house. After O'Brien remarked that Claudius was clearly getting emotional about it, a heavily mutated Tubian named Zaggothua had suddenly appeared in the pool & attacked O'Brien. The two alien sea monsters duked it out in a brutal fight, with O'Brien dismembering the creature & obliterating it with his Finalizer beam.
O'Brien made a brief appearance on August 3rd, 2017, when he alerted Golmon Osseo that Rob Oftolenov was trying to get his attention, but Golmon ignored both of them just to that he could dig in a horseshoe pit.
19 days later, O'Brien was hanging out in the pool with Jack & Imhotep, talking to Claudius about the currently deceased Babyman. He then asked Claudius if this was the day & place where he'd be meeting up with a couple of people to serve his "glorious cause". Claudius confirmed that it was, but asked if O'Brien questioned his methods. O'Brien then stated that despite understanding Claudius' goals, he thinks Dan should be the one to rule planet Earth, not him. Instead, Claudius can become one of the Irken Invaders, with O'Brien seeking to one day join them, as well. But Claudius declined his offer, believing that if he is to one day perfect the world as he saw fit, he must do it himself. Still, he noted that he'll remember O'Brien's words if his plan were to fail. O'Brien shifted the subject by pointing at the cornfield, where Dangerous Man & Shadowballa came out of & rendezvoused with Claudius in the backyard. The three would leave soon afterwards, with O'Brien expressing his concern that one of the topics in their discussion was about his home world, & that he refused to talk about it, saying that he's got a problem. Dan appeared out of nowhere, agreeing with O'Brien, but remarked that if anyone here had a problem, it was him; he does eat babies, after all. With O'Brien claiming that he only eats "the ones they don't want", Jack & Imhotep emerged from the water, fused together to become known as Jackhotep.
Nineteen days later, O'Brien was hanging out in the pool with Jack & Imhotep, talking to Claudius about the currently deceased Babyman. He then asked Claudius if this was the day & place where he'd be meeting up with a couple of people to serve his "glorious cause". Claudius confirmed that it was, but asked if O'Brien questioned his methods. O'Brien then stated that despite understanding Claudius' goals, he thinks Dan should be the one to rule planet Earth, not him. Instead, Claudius can become one of the Irken Invaders, with O'Brien seeking to one day join them, as well.

With O'Brien claiming that he only eats "the ones they don't want", Jack & Imhotep emerged from the water, fused together to become known as Jackhotep.
On September 4th, during the 9th Super Battle Bros. Tournament, O'Brien had informed his emperor about the many people who would be attending the battle on that day. This would also be the first official tournament to be documented, as no other battle in this game had been recorded before. When the tournament began, O'Brien was one of the first to fight, combating against two of Doombringer's failed experiments: Bootleg Stupid Mickey & Prototype Stupid Mickey. Both of these rodents would lose to Toy-Toy Ninja Man later on, while O'Brien would have to deal with Eggward, but both of them would encounter the Screaming Boy himself, Acoutor. To this day, it's still unknown as to who won.
On the 17th, O'Brien was lounging in the pool with Axel Rathorn & Billy Mays. Apparently, the part of the video they were in was merely filler, with O'Brien complaining about being the "time card".
=== Battle Against the Beast ===
When the Deep Creeps unleashed a terrifying monster named the Beast to wipe out all life on Earth, O'Brien was enlisted along many others by Dan, Claudius, & Dr. Zackary Vore to help defend the planet against this monstrous enemy. O'Brien did not participate very much in this epic battle, as he was actually somewhat afraid of the Beast. Nevertheless, he did help during the final battle the Beast had with Dan, firing his strongest attack alongside Sdrawkcab, Jackhotep, Princess Twilight Sparkle, & Asmodeus. This gave Dan the opening to send the Beast through the window of the Dimenchamber, scrambling his atoms across the Multiverse. After Dan & Asmodeus roared in victory, the latter counted the lives that were lost fighting against the Beast. To lighten the mood, O'Brien reminded everyone that it's Halloween & that they should be celebrating it along with their victory. He even reminded Dan about a certain clown that was supposed to visit this night, to which they all went outside to watch Pennywise perform its Dance of Doom under the full moonlight.
=== Celebrating Earth's Holidays ===
On December 15th, Santa Maria had paid the Ledda Residence a visit to inspect the Christmas tree, as well as briefly visiting O'Brien. He was under the impression he was going to get presents early, but Santa was actually on a mission to find Dan & tell him something important. O'Brien told him that the Tallest would be in his room, but warned about a very strange occurring in the bathroom next to it. Santa's curiosity got the better of him & witnessed Sdrawkcab, Jungle Man, & Dinosaur Man doing a bunch of weird stuff. After seeing that Dan was sound asleep, Santa decided that O'Brien be the one to deliver the news to him; that news being that more supernatural entities will be revealed on Christmas Day.
When that day came, O'Brien was sleeping on the guest bed in Dan's room. Twilight woke them both up, & they were all very excited in this joyous Christmas morning. What O'Brien was excited for the most wasn't the presents, but the free food, gorging in on some homemade cookies. Later on, a Fruit Vampire appeared, with O'Brien presenting some cranberry juice for it to leave the house satisfied.
On March 15th, 2018, O'Brien was talking with Claudius at Dan's place, warning him that their emperor has been running more security protocols than usual as of lately. These were done to make sure that there were no traitors lurking within the empire. Claudius was hoping that the Ides of March weren't to blame, but O'Brien assured that they were. Claudius was about to mention Dan's Human friends, but he stopped upon hearing a menacing growl from behind the door to his room. O'Brien also suggested that Claudius should do some security protocols on his henchmen, too, but Claudius deemed all of this as superstition & left, with O'Brien wishing him a happy St. Patrick's Day on his way out. Later that day, O'Brien came downstairs to see what Claudius was up to, who told him that Maniacman betrayed him & that O'Brien was right about suggesting a loyalty checkup on his minions. O'Brien then asked what that peculiar amulet was that Claudius had with him. The diamond within the amulet was what remained a mystery to Claudius, who gave it to O'Brien & asked if he could bring it before the Tallest to figure out what it truly was. After O'Brien brought it to his master, Dan kept the diamond for safe keeping. Months later, it was discovered to be a vessel for the Power Stone.
O'Brien made a very brief cameo on April 1st when Dan had discovered an unusual conspiracy that April Fools' Day & Easter were on the same day.
=== Contracting the Blue Flu ===
O'Brien would not return until a Super Battle Bros. Tournament on July 1st, where he fought & defeated Phlotacle, disintegrating him with the Finalizer.
On August 1st, O'Brien has a brief encounter with Fallaballa but didn't get the chance to talk to him because he scared Falla by accident, running away from him. Four days later, O'Brien would attend the biggest Super Battle Bros. Tournament at the time, where he sparred against Jack. Their beam clash seemed close, but O'Brien's sheer power earned him a victory against the mutated pumpkin man. Moments later, Dan had announced that a new stage has been unlocked for Splash Bros, which would be at the Fall Residence. Anyone who was still in Dan's pool was given permission to go there, but O'Brien stayed because he felt a bit sickly, stating that he was coming down with something. Dan felt remorse & allowed him to stay & have a well-deserved rest. O'Brien was grateful not only for that, but the fact that he had Gillman to keep him company. When the tournament was over on that day, O'Brien was transported back to his home planet, where he found out that he was diagnosed with blue flu.
O'Brien was quarantined in Dan's guest bed on September 1st. Though he claimed he still didn't feel so good, Dan assured him that everything would be alright, since Vendu & Claudius were preparing a remedy called Super Soup that would cure his illness. O'Brien was thankful, but was also bitter, demanding to know why Dan didn't use the more recently acquired Infinity Gauntlet to cure him. Dan thought about this before, but decided not to use it as a means of teaching everybody not to rely on him like he's some kind of godly miracle-worker. O'Brien understood, then they reminisced on when he had the blue flu in 2013 & when Fallaballa had the same illness in 2016. Dan then left O'Brien alone to rest. Lidman would come in & visit him moments later, & they both found it very surreal that their voices sounded oddly similar. The mentioning of the word "surreal" summoned Meme Man to stop by quickly. As time went by, the battle going on in the pool outside was getting very heated, with a substantially large amount of combatants being present. O'Brien watched as they fought, & expressed utter contempt at the fact that he couldn't have fun with them. He was especially upset because Tubias was there. After hearing a ghostly whisper from the Infinity Gauntlet perched atop a podium, O'Brien demanded for Vendu & Claudius to finish the soup, to which Vendu stated "You can't rush perfection!" Minutes later, the soup was finally done, & Claudius went upstairs to give it to his friend in need. The soup's effects worked instantly, with O'Brien emitting a bright purple flash as he returned to normal. The Rhaatror felt empowered & was very grateful for his friend, proudly marching outside as he finally got to fight his rival again. As he announced himself & jumped in the pool, O'Brien & Ultraman combined their beam attacks to finally defeat the King of the Tubians, who was weakened & gave up, leaving the match.
=== Imperial Visits ===
Twenty days later, O'Brien would return to Dan's house once again, albeit briefly, to hang out with him & some friends. O'Brien & Vendu were upstairs as Dan was painting something. Because of Vendu's sort-of-British-accent, he didn't know if Vendu said "the artist is at work" or "the autist is at work", to which Vendu said yes to both. O'Brien was confused.
At the very end of the year, O'Brien alerted Dan that the Fruit Vampire from last Christmas had returned. Dan saw both a bottle of Sprite & a jug of cranberry juice & didn't know which one to give to the creature, so he magically combined them into a Sprite Cranberry, telekinetically moving it out of the house as the bat followed. It is unknown if O'Brien was present during the rest of the festivities later that night.
O'Brien was present at the Ledda Residence on January 22nd, 2019, where he witnessed the beginning of Birdman's final evolution, but he didn't seem to care much of it.
On May 9th, O'Brien watched Dan's college graduation ceremony live alongside Imhotep, Jack, Cyclome, Twilight, Dr. Zackary Vore, Vendu, & Claudius. Biggus & King Richard I were also present, but were not in the living room. They all sat patient & potent, not uttering a word until they saw Dan appear on the TV, which sparked massive excitement. Dan teleported back a couple hours later, coming home to many kind words from his friends, who then bowed to their emperor. However, Zack, Claudius, & Richard knelt instead; they didn't feel like bowing. As the rest were hailing the Almighty Tallest, O'Brien kept hitting his head on the floor, which prompted him to ask if they could stop hailing. Dan was pleased & smiled ominously before teleporting upstairs.
=== Participating in Great Battles ===
O'Brien would not return until June 15th, where Dan announced the first Splash Bros. Tournament of 2019. Imhotep, Jack, Bullet Man, Biggus, Toy-Toy, Hydrion, & O'Brien all showed up, eager to finally face off in the pool. However, upon entering, O'Brien found the pool to be a bit cold, which prompted Dan to use the Infinity Gauntlet to pull the Sun slightly closer to the Earth, warming it up while also ignoring the laws of physics. After Imhotep remarked him for his ingenuity, the battle began, & O'Brien met a new face: Shark Puppet. They didn't have much to say to each other.
Two days later, O'Brien would fight in another tournament including Darth Kaidus, Barbarius, & a newcomer from the East Dimension named Cauldron Head. Not much is known of this event, but Cauldron Head was able to steal O'Brien's Plasma Beam ability before being ultimately defeated by the three, who all teamed up against him.
On Dan's birthday, O'Brien, Twilight, Imhotep, Jack, & Birdman heard a distress call from their emperor, who was under attack by King Hastur, President Valak, ZoZo, & Dr. Victor Zolostene. Dan was stabbed in the heart by one of Hastur's tendrils, so in pain, he let out a Sonic Roar that alerted his allies, echoing across the land. Twilight led the assault & used her magic to teleport the Infinity Gauntlet onto her hoof, & she proceeded to use an intimidation display to force the villains to retreat. Despite Twilight appearing first, O'Brien & the others were late by a couple minutes because they were not as fast or as perceptible as her. O'Brien demanded to know who hurt the Almighty Tallest, to which Dan explained. O'Brien didn't do much else while he was present, but Dan appreciated everyone showing up anyway.
On August 24th, O'Brien participated in the biggest Super Battle Bros. Tournament of all time, a dual-map tournament including 26 combatants. In the pool at the Ledda Residence he sparred with Toy-Toy Ninja Man, Jack, & the Barfallonyou twins before Cauldron Head would show up. After explaining to a curious Halloween Ninja how he knew about Cauldron Head, the two fired their beams at each other as Halloween Ninja would hide underwater. Caught in a clashlock, Cyclome then joined in & caused a great explosion to knock Cauldron Head down for a bit. Once he got up, he taunted Cyclome & got him to fire his Ozone Beam at him again, but Cauldron Head absorbed it with his cauldron. Biggus, who was watching all of this was shocked to see that under the cauldron, there was no head on this man. O'Brien tried to warn Cyclome about Cauldron Head's ability to mimic powers, but it was too late & the Doamhed was knocked out. O'Brien was ready to face off against him, but Legit Ant-Man made a surprise appearance & knocked Cauldron Head's cauldron off. O'Brien & Jack then combined their beams in a Gamma Finalizer, finally knocking out Cauldron Head. Suddenly, a new challenger walked onto the battlefield: the Scissorman. Since neither Biggus, Ant-Man, or Jack could halt the Scissorman right away, O'Brien was about to take him on, only to be kanchoed by Halloween Ninja, who made a hasty getaway. HowToBasic then appeared out of nowhere & threw a slice of ham at the Scissorman's face, rendering him unconscious. It is unknown what else O'Brien did for the rest of the tournament.
O'Brien was one of the 14 people who accompanied the Almighty Tallest during the Area 51 Raid on September 20th. His roar struck fear into the hearts of those who guarded the site, & his plasma would incinerate anyone who got in his way as the Illuminati & their subordinates would obtain the secrets of this place. Oddly enough, though, it would seem O'Brien was not made aware of the Illuminati's existence, simply assuming Dan's choice of invitees to be those he trusted with this operation.
On October 4th, O'Brien read an article about how eating babies would reduce the amount of carbon dioxide in the atmosphere & curtail climate change. O'Brien declared he would eat more babies than usual to keep his title. Dan was disappointed with his decision, but did not blame O'Brien, rather the woman who wrote the article in the first place, calling the USA a freakshow & being born in it as being given a front row seat to it.
=== Fleeing from the Coronavirus ===
With the swamps on Rhylota finally being cleaned up after all these years, O'Brien would remain comfortable on his homeworld. Sure, the ecosystems have changed slightly, but this was not a negative change made to the planet. A negative change on another planet, however would be much worse, as the infamous Dr. Victor Zolostene unleashed the Coronavirus onto the Earth at the very end of 2019. All Super Battle Bros. Tournaments planned for that year were postponed until the virus would be dealt with, giving O'Brien two good reasons not to visit Earth.
Ten days after Dan killed Zolostene & eradicated the virus with some help, his birthday was celebrated & O'Brien would finally come back to Earth. However, he made landfall in Jacksonville, Florida, where he allegedly encountered & escaped from the feared Chin-Chin. Jumping into Dan's pool, O'Brien would partake in the grand reopening of Super Battle Bros. by fighting Commander Joshua Bunch, Han Velsing, & Blue Shirt Shaggy. While Han's main defense was an Acid Gun, it wasn't able to do too much to O'Brien, leaving Josh & Shaggy as the ones he'd struggle with most. Josh was holding back but still dealt substantial damage to O'Brien, & he seemed pretty evenly matched with Shaggy. Who won the battle is unknown.
O'Brien was invited to Dan's house for Christmas later that year, but he wouldn't let Imhotep have any of the cookies, hoarding them for himself.
=== A Changing World ===
O'Brien would return to Earth on June 19th, 2021, where he would spar with Imhotep & Shark Puppet, the former providing a big challenge since Imhotep had been training to hone his magic abilities. O'Brien had no real counter to them, being confused by the nature of the Mummy's spells & dismissing them as nonsensical. Shark Puppet, however was a much easier opponent. Despite achieving his Great White form & becoming 100 times stronger, it was not enough to defend him from getting slapped out of the pool in one hit. Several minutes later, the sky broke apart, revealing the quantum foam of the universe. This was because the reality warping beings Pandamonium & Trip Man were released from the Pentalock. They fought Dan in his room, & the former was using his powers to mess up everything around him, wanting to make Dan's friends suffer for his humiliating defeat in 2017. O'Brien saw that the pool water was replaced with blood & his arms were turned into guns. He fired them away in frustration. Imhotep was frozen in a permanent T-pose & Jack was transmuted into one of the trees in the front yard. All O'Brien, Tigriton, & Claudius could do was pray that Dan would win against these interdimensional threats. Fortunately he defeated them both by snapping them out of existence with the Infinity Gauntlet, undoing the effects of their powers. O'Brien was happy to have hands again, but was confused as to what just happened. Hydrion then appeared from inside the house to explain that Pandamonium & Trip Man were eliminated. Claudius explained that the Pentalock could not be opened from the inside, leading O'Brien to believe that those two were released intentionally. As for why, Imhotep concluded that this was Dan's way of "eliminating the competition", getting rid of any enemies who are still alive & a threat to the universe.
O'Brien was invited to Dan's birthday party on July 22nd, 2022, where he did battle with Shark Puppet in the pool, which only lasted a few seconds. But he would have bigger fish to fry, as Jack appeared, boasting a new form he unlocked that would turn the tides in his favor. O'Brien cancelled Jack's transformation by throwing a Plasma Bolt at his face, but he let Jack finish transforming when offered the chance of a fairer fight. Becoming Jack Black, O'Brien dissmissed it as Jack just changing his color scheme, but would be proven wrong when the two were evenly matched in a beam-clash. Claiming he lacked variety, Jack caught O'Brien off-guard with a couple of Shadow Tendrils, allowing him to blast him out of the pool. O'Brien dejectedly got back in the pool & claimed this was only the beginning of their battle as they swam towards each other. The victor remains unknown.
On July 4th, 2023, O'Brien was at the Ledda Residence for an Independence Day celebration along with some others. But Dan made a hasty exit to go to Washington, D.C, where he would fire at the White House, the Capitol Building, the Supreme Court Building, & the Pentagon with his Atomic Breath, laying waste to the nation's capital. Footage of this was being broadcast on the news, which made Cyclome, Jack, Heartman, Dr. Sack, O'Brien, & Imhotep become a choir of panic. Claudius then appeared to explain why all of this was happening; Doctor Doom had returned from the Quantum Realm after four years of absence, announcing to the world that he'd be running for President of the United States. Dan took this personally & enacted a secret contingency plan to wipe the slate clean for America, eliminating its infrastructure. Zack concluded that this would be done so that Doom would be left resourceless & would put Dan a step ahead when it comes to taking over the country. O'Brien deemed it a little excessive, but Heartman said it wasn't so compared to what Dan's done before. Minutes later, they saw the newsfeed cut to static as every nuclear weapon on the planet was launched at Dan simultaneously, creating a massive explosion visible from space. The radiation plume from all those nukes had spread across the country, turning the sky into a hazy yellow, so everyone stayed inside while Jack & Cyclome would absorb the radiation outside to help out the nearby town. Minutes later, Dan came back & explained himself, stating that if Doom were president, he would find a way to take over the rest of the world, which would conflict with Dan's conquest. O'Brien would go back to Rhylota sometime after the news came back on, showing Doom revealing Dan's identity to the public & calling him out for what he did. O'Brien deemed this an Earth matter he would not participate in.
== Personality ==
O'Brien is a ferocious predator, attacking any weakling who dares to oppose the Monirken Empire. He is a highly determined fighter, having devoted his life to being the strongest he can be. But he's not actually a heartless killer; he cares for his friends deeply. For example, he shows genuine concern for Claudius, as evident by the Chlorosapien's refusal to discuss anything regarding his past. O'Brien will look out for others, as he believes it's the right thing to do, & he does indeed show remorse for those who suffer, but only if they aren't enemies of his. Although, his morality is put into question when accounting for the fact that he eats babies of varying species, usually Humans, even if they're specifically unwanted ones.
== Powers & Abilities ==
=== Physical Abilities ===
Rhaatror Strength: O'Brien is incredibly strong, as he is known as the strongest living member of his species. He was able to single-handedly take down Zaggothua, combat Bootleg Stupid Mickey & Prototype Stupid Mickey simultaneously, & even fought Dan, Jake, & Owen all at once when they were younger. He was also able to combat against Josh & Blue Shirt Shaggy, though the former might've been holding back. He has outclassed Jack in terms of strength & power & has fought King Tubias more than once. His combative prowess has earned him a special seat amongst his Imperial friends. He is strong enough to destroy a country.
* Head Slam: Because of his build, O'Brien has a technique he calls the Head Slam where he lifts up the upper part of his body & slams it on his opponent. This attack has a lot of concussive force.
Rhaatror Speed: O'Brien's moving speed is rather low, only having the running speed of a Human, but he can swim & fight at much higher speeds. His combat speed is in the massively hypersonic range since he has sparred with Jack more than once. At his maximum, O'Brien can react to lightspeed attacks since he's matched Jack's Gamma Rays more than once.
Durability: O'Brien has a very tough & durable body, being able to take a hit & give it back twice as hard. He has withstood a barrage of punches from Toy-Toy Ninja Man & Blue Shirt Shaggy, the acidic vomit of the Barfallonyou twins, the lashing tendrils of Zaggothua, the full force of Eggward's egg, & Jack's Gamma Rays. He was able to win against Bootleg Mickey & Prototype Mickey simultaneously & has even fought Kaisers before. He is tough enough to survive the destruction of a country.
Shielding Mode: O'Brien can enter a different physical state that turns his torso around but not his arms, & it reveals an orifice that can fire projectiles. It also makes his front side look bulkier, which is an evolutionary tactic to look more intimidating, not unlike mammals being able to puff up their fur to look larger.
Adept Swimmer: As a sea creature, O'Brien is naturally adept when it comes to swimming.
Amphibiousness: O'Brien can breathe on land & in water. His body doesn't even need to be moist when he is on land, but he does perform better when in water.
Bioluminescence: O'Brien can make his eye glow a bright blue. He doesn't do this a lot when he's not shooting lazer beams with it, but he was seen with a glowing eye during the Area 51 Raid.
=== Special Powers ===
Ionikinesis: O'Brien, like all Rhaatrors, can manipulate plasma to an extent. Because of this, O'Brien has developed a few of his own techniques.
*Plasma Bolts: O'Brien can hurdle spheres of plasma from his hands, & can release multiple spheres at a time. This is his quickest attack, though it is not as potent as his other plasma attacks.
*Plasma Grenade: O'Brien can discharge a plasma burst from an orifice on his body. It is green in color & creates explosions upon impact. It can completely vaporize organisms, as seen when he killed a Tubian in Almighty Tallest Danny's 2016 Birthday Special (PART 1).
* Plasma Beam: From that same orifice, O'Brien can fire a focused lazer beam that is blue in color. Though not as destructive as the Plasma Grenade, the Plasma Beam has more range.
* The Finalizer: This was once classified as O'Brien's finishing move, but because he uses it so often now, it can't really be considered his finishing move anymore. The Finalizer occurs when he focuses all of his plasma energy into his eye & releases it in a bright blue beam that can level a country. Most of the time it's a one-hit-kill, like when he used it to vanquish Zaggothua & Phlotacle. It is also stronger than Jack's Gamma Rays & Cauldron Head's Emerald Embers. He can tone it down if he wishes not to kill his opponent, like what he did with Prototype Stupid Mickey & Blue Shirt Shaggy. This beam was also used against the Beast, & while it didn't really damage him, its light combined with the light from the other beam attacks fired at him at the moment helped distract him.
Armed Arms (formerly): Due to the effects of Pandamonium warping reality, O'Brien's arms were once replaced by guns. They even came with ammunition, & he angrily fired them into the distance because he did not want guns for arms. Fortunately, after Pandamonium's deletion, O'Brien's arms turned back to normal.
== Weaknesses ==
As strong as O'Brien is, the massive muscles which construct his body cause him to be considerably sluggish in his movements, although not as bad as Lidman. His arms are also rather disproportionate to the rest of his body, not unlike a Tyrannosaurus Rex. He has also been shown to be vulnerable to Bootleg Stupid Mickey's Bootlegify power, though he managed to push through it. He has no special resistance to magic, as he was susceptible to Imhotep's Gey Bolj. 
== Trivia ==
* His name is a direct reference to a joke character of the same name from Muppet Treasure Island.
* It is unknown why exactly he eats babies, but he claims that they're delicious & good for his health. Based on what he says in Claudius' Quest - Episode 5: Shades of Villainy, he only eats aborted babies, even though how he obtains them is unknown. Josh calls him a "living abortion clinic" because of this.
* He, Lidman, & Drowzon II have very similar voices.
* When he roars, he either sounds like a crocodilian or the 1976 incarnation of King Kong, who uses stock sound effects that other monsters in movies & video games have used like the Deadly Mantis.
