#1 Feedback
Get ready you dumb robots, because Feedback's going to come out on top!
Species: Conductoid
Feedback's DNA was sampled from a Conductoid, a species of living electric cables from the Teslavorr Nebula, with the ability to absorb and redirect energy.- Bizarre Alien Limbs: Feedback sports two tendrils on his head that can act as Combat Tentacles. Izuku's observation of them indicates that they may have some form of sentience. When Jiro sees them, she can't help but think how similar they look to hers.
- Energy Absorption: Once he latches onto any source of electricity, he'll siphon it all and uses the power as an offensive attack. He can also absorb energy from lasers.
- Feedback's "Blackout Surge" has the Conductoid drain all the power from a target till it shuts down.
- Energy Weapon: Feedback can fire powerful beams from the energy he absorbed. A fact he learned when fighting the Techadon.
- Lightning Bruiser: He possesses a credible amount of superhuman strength all the while being able to be fast and agile. In fact, Aizawa ranks Feedback in second place in the Quirk Apprehension Test, only behind Four Arms which is ranked in first place.
- Mundane Utility: In chapter 48, he's used to recharge the Ruskbucket's battery.
- Shock and Awe: Feedback's primary ability.
- Super-Senses: Feedback can detect electrical sources, even ones that are hidden from plain sight. This makes him useful in tracking down the mischievous Megawatts. He is also able to pick up radio waves which were how Midoriya got word that Bakugou is in danger.
#2 XLR8
Take care of yourselves. Now, I gotta run!
Species: Kineceleran
XLR8's DNA was sampled from a Kineceleran, an incredibly fast-moving species from the planet Kinet.- Animal Motif: Tsuyu and Present Mic take note of his raptor-like appearance.
- Keet: When as XLR8, Midoriya can be a tad too excitable.
- Rapid-Fire Fisticuffs: With his speed, XLR8 can deliver rapid attacks.
- The "100 Cuts" Special Move is when XLR8 speeds in and uses his claws to deliver multiple slashes at his opponent.
- XLR8's Ultimate Move, Velocicrush is the alien delivering rapid-fire kicks before swinging his tail as the final blow.
- Reflecting Laser: XLR8's "Halo Run". By using XLR8's claws, Midoriya reflects the sunlight against Tokoyami's Dark Shadow who is weakened by light.
- Spin Attack: "Beyblade Burst" has the raptor-like alien spin around with his claws stretched out, transforming him into a living saw blade.
- Super-Speed: XLR8 can reach up to speeds that can rival and possibly surpass Tenya Iida's Quirk.
- In fact in the "How It Should Have Ended" version of Chapter 21, XLR8 can easily speed past all the challenges at the Obstacle Race and win much to the dismay of just about everyone in the entire universe.
- Tornado Move: His "Blue Twister" will suck in anything, even a person.
#3 Grey Matter
Now I'm about to win a race of speed and athletics with pure brainpower.
Species: Galvan
Grey Matter's DNA was sampled from a Galvan, a species consisting of small, incredibly intelligent frog-like beings from the planet of Galvan Prime.- Heart Is an Awesome Power: Despite his many drawbacks, Grey Matter can be used effectively if the situation is right up his alley. His tiny form, combined with his Super-Intelligence, makes him the perfect infiltrator and saboteur.
- Incredible Shrinking Man: Midoriya transforms from a slightly average-height teenager to a 6-inch tall little guy.
- Super-Intelligence: While already brilliant at a young age, Grey Matter enhances Midoriya's intellect to heights that he can only think of in his dreams.
- Wall Crawl: Grey Matter can stick onto surfaces, allowing him to climb up to high places.
- What Kind of Lame Power Is Heart, Anyway?:
- His small stature makes him a very vulnerable target if one actually notices him.
- As demonstrated in Aizawa's tests, Grey Matter is not physically superior and by the end of it, he is ranked the lowest compared to the other Omnitrix aliens and Izuku in his human form.
#4 Four Arms
You're going to have to pry it from my cold dead hands.
Species: Tetramand
Four Arms' DNA was sampled from a Tetramand, powerful 12-foot tall aliens with four arms and armor-plated skin from the planet Khoros.- The Big Guy: He's one of Midoriya's heavy hitters and the most physically intimidating in his arsenal. Also, with Midoriya running the form, Four Arms can invent creative ways to take down opponents that can pose a problem to him.
- Exactly What It Says on the Tin: He's an alien, with four arms. Really thinking outside the box with that one, huh?
- Grievous Harm with a Body: "Strong Arm Toss" has Four Arms grab a nearby enemy and throw him into the latter's compatriot.
- In a Single Bound: His legs can launch him up into the air over a great distance.
- Multi-Armed and Dangerous: A large behemoth with four big arms that can tear all of a person's limbs off in an instant.
- Shockwave Stomp: "Four Arms Smash" is basically a ground-pound attack. Midoriya uses this to deter Tsuyu long enough for him to take her down.
- Super-Strength: The Tetramand's signature ability. In fact, Aizawa ranks him first above the Omnitrix aliens in the Quirks Apprehension tests.
#5 Ditto
If you mess with me, then you mess with all of me!
Species: Splixson
Ditto's DNA was sampled from a Splixson, a race of small humanoids able to create unlimited duplicates of themselves from the Earth-like planet Hathor.- Awesome, but Impractical: Despite being able to produce an infinite amount of clones, the drawbacks heavily outweigh the benefits, among which is their Weaksauce Weakness, lack any physical prowess, and, on some occasions, their lack of unison with each other. Even the cloning ability can be a detriment to Midoriya as he'll remain as Ditto if all his clones are not present to merge back with him further complicating things.
- Deadpan Snarker: Transforming into his Ditto form, Midoriya develops some and in his own words, "sass".
- Dog Pile of Doom: An improvised special move "Dogpile" has Ditto and his clones....dogpiling on his opponent.
- Doppleganger Attack: In a matter of seconds, Ditto can build an army and overwhelm his opponent.
- Me's a Crowd: The main ability of Ditto and his species.
- Weak, but Skilled: Despite the severe problems he provides, Ditto can be pretty useful once someone finds a way to work around said problems. Something that Midoriya and Gang Orca tries to solve.
- Weaksauce Weakness: A very BIG drawback with this alien is that he and his clones are completely linked to one another meaning that if one of them is to get injured, that pain will be shared with the others. Furthermore, if one of the Ditto were to perish, the other clones will suffer the same fate.
#6 Ripjaws
I think it's time to go after the whopper.
Species: Piscciss Volann
Ripjaws' DNA was sampled from a Piscciss Volann, a race of angler fish-like aliens from the literal water world of Pisciss.- Absurdly Sharp Claws: Ripjaw's claws can shred through almost anything.
- Creepy Good: He looks like a monster but is part of Midoriya's arsenal. His monstrous appearance does make him mistaken as a villain.
- Crippling Overspecialization: Ripjaws is a great asset in underwater combat. However, he's practically ineffective as a fighter on land. Even if he can, he'll suffocate from the lack of water minutes after stepping onto the ground.
- More Teeth than the Osmond Family: His mouth is lined up with bizarrely, large and razor-sharp teeth that can rip alien metal like it was tissue paper.
- Our Mermaids Are Different: His legs can merge into one large fin allowing him to traverse or speed through the water in just seconds.
- Super Not-Drowning Skills: As an aquatic-based being, Ripjaws can breathe in water for an extended period of time.
- Weaksauce Weakness: Ripjaws can't survive on land for long without water.
#7 Terraspin
Can…someone flip me over?
Species: Geochelone Aerio
Terraspin's DNA was sampled from a Geochelone Aerio, a peaceful and innocent turtle-like alien species from the planet Aldabra in the Andromeda Galaxy.- Blow You Away: Terraspin "spins" his fins to generate powerful whirlwinds or tornadoes.
- Also, his air generation allows him to propel up into the air, giving him the ability to fly.
- Terraspin's "Turtle Power: Buzz Saw" has Terraspin flying in and using his fins to act as spinning blades.
- Face of a Thug: Due to looking like a giant turtle, All Might mistakes him as part of Dr. Animo's mutant animal army.
- Flight: Terraspin's Tornado Move allows him to propel himself up into the air. Midoriya uses this most effectively at the U.A. Sports Festival Cavalry Battle.
- Spectacular Spinning: This is how he activates his wind abilities.
- Tornado Move: It's part of his skill set.
- His special move "High Winds Tornado: EF0" has him produce an air attack that sucks in enemies.
- Another move "Updraft" is him producing a whirlwind that sends anyone flying.
- Weaksauce Weakness: Like a real turtle if Terraspin is knocked on his back he can't get back up.
#8 Water Hazard
Sorry, to rain on your parade. But we're just getting started.
Species: Orishan
Water Hazard's DNA was sampled from an Orishan, a naturally armored molluscan alien race from the planet Kiusana in the Andromeda Galaxy.- Making a Splash: Water Hazard can shoot pressurized water streams that can send people flying. He can also absorb moisture through his portholes and alter the temperature of the water he shoots. Water Hazard also possesses some form of Hydrokinesis.
- Water Hazard's "Fire Flow" has the alien firing vast amounts of pressurized water which even sends Gang Orca reeling.
- Man of Kryptonite: Out of all of Midoriya's transformations, Water Hazard is the worst alien Bakugou has to face.
- All of Bakugou's attacks can't even get past the crustacean-like alien's armor, not even tickle him.
- Water Hazard shoots out water which is an element that can render Bakugou's nitroglycerin ineffective.
- Nigh-Invulnerability: His exoskeleton is very durable that Bakugou's explosions can't put a dent on it.
- Tornado Move: Water Hazard has two special moves.
- His attack, "Deep Six Torpedo", involves propelling forward using his water powers and spinning around to be engulfed by the water, turning him into a whirlpool.
- "Tsunami Vortex" is Water Hazard creating a raging whirlpool that swallows enemies.
#9 Lodestar
Man, the first day and I'm already losing my head.
Species: Biosovortian
Lodestar's DNA was sampled from a Biosovortian from the planet Biosovortia.- Floating Limbs: His head is separate from his body... somehow.
- Losing Your Head: That's what happens when your floatless head is blown away by an Explosion Quirk. Thankfully, the head is still functional and the same goes for the body. However, if the head of the alien is destroyed, it won't work.
- Magnetism Manipulation: Whether it's your coin, toaster, or plane, Lodestar can take control of them easily. Of course, he is unable to take on anything that doesn't have a bit of metal in it.
- Pulling Themselves Together: As Lodestar, he is fully capable of gathering all his damaged parts back together from attacks that are considered fatal to human beings. It's a good thing Lodestar has that ability otherwise Bakugou would've been charged for manslaughter.
