He can duplicate himself, but unlike Ditto, the clones are not linked in any way and can revert to human form even if all duplicates are not re-integrated. His Ultimate form has the ability to fly and wields sonic discs that amplify his sound blasts, but is unable to duplicate.
- 49. A Prypiatosian-B, an energy-based alien from the planet Prypiatos. He is a radioactive energy being encased within an oven-like invulnerable containment suit that contains his radiation. When released, he can shoot energy beams, create intense heat, and become intangible, so he cannot be touched except by the material his armor is made of.
- 51. An Ectonurite, a one-eyed ghost-like creature from the planet Anur Phaetos. Ectonurites normally have a protective skin that condenses their form to resemble ghosts, their eye moving along a black track on that skin. Ectonurites can phase through matter, possess people, turn invisible and fly. They are stronger in darkness and can be weakened in sunlight to the point of death by combustion.

Among a Florauna's abilities are extending limbs, thorns, generating explosive seeds, merging with other plants, and regenerating from near fatal attacks. In the reboot, he is redesigned to be bipedal.
- 2. A Chronosapien, a robotic alien from an unidentified planet. Capable of traveling through time and space, Chronosapiens can produce time rays that can either age or regress their targets or slow everything down around them. They can display events that have happened in the past by rotating the keys on their heads, which creates holographic images of past actions.
- 4. A Methanosian, a plant-like humanoid from the planet Methanos. Besides being able to control plant life and producing seeds that quickly grow into vines, he also has a vast regenerative ability that allows him to regenerate lost limbs. In Omniverse, he undergoes a puberty-like process, gaining enhanced abilities and a red and yellow color scheme. Ultimate form resembles a tree and has blue napalm-like sacs across his body.
- 5. An Atrocian, a rotund alien from the planet Atrocian. He is highly durable and virtually indestructible, but is not immune to pain.

- 9. An Arburian Pelarota, a hulking, broad-shouldered alien covered in natural armor plating. By curling up into a ball, he can encase himself in his armor, becoming virtually invulnerable. The drawback is that he quickly picks up momentum, which can make hitting more agile targets difficult, as he cannot slow down quickly; in addition, his speed and maneuverability is limited outside of his ball form, owing to his bulk and high center of gravity. Ultimate form has a gray shell covered in spikes that he can shoot as projectiles.
- 10. An unidentified robotic alien from an unidentified planet. He is able to mix and generate gas from inside his body, which has a large, transparent stomach that leaves the gas visible.

- 12. A Necrofriggian, a moth-like alien from the planet Kylmyys. He can become intangible and freeze an opponent in various ways, one of which utilizes intangibility to freeze anything that he passes through.

- 19. A Tetramand, a red four-armed alien from the planet Khoros. He has an extremely dense musculature, making him unmatched in pure physical strength; however, he is slow and unable to use things normally used by smaller creatures. Using his strength, Ben can create shock waves by pounding the ground or clapping all four of his hands together, and his leg strength allows him to cross entire city blocks in a single jump.
- 21. A Gourmand, a reptilian alien from the planet Peptos XII. Gourmands are small frog-like aliens with a very large appetite, their four adhesive tongues stretching out to latch onto large objects and swallow whole. As Gourmand's mouths and stomachs stretch to facilitate the digestion, the latter converts the ingested matter into explosive balls of liquid that can be expelled at will.
- 23. A Celestialsapien, a humanoid alien from the Forge of Creation, a region outside the universe. He has vast reality-warping abilities coupled with two split personalities: Bellicus and Serena, who prevent him from acting until Ben convinces them to. Theoretically, he possesses limitless power, as any thought he conceives can be transformed into reality if all split personalities agree.
- 24. A Viscosian, a humanoid slime-based alien from an unidentified planet. He has a malleable, slime-like body with shapeshifting capabilities and can generate acid. He utilizes an anti-gravity generator resembling a small flying saucer that allows him to retain mobility in Earth and other environments that have higher gravity that his home planet.
- 25. A Planchaküle, a gremlin-like alien from the planet Aul-Turrhen. He has innate engineering abilities and can disassemble and reassemble machinery into new forms. In Omniverse, he wears an aviator's suit, which includes goggles and a scarf.

- 37. A Nosedeenian, a battery-like alien from the Nosideen Quasar. Commonly referred to as Megawhatts, Nosedeenians are battery-like energy beings who can manipulate electricity, travel through any electrical source at high speeds, and reproduce via mitosis once they gather enough energy.
- 39. A Lepidopterran, a quadrupedal insect-like alien from the planet Lepidopterra. He can fly at high speeds and generate adhesive slime with various properties. If his wings get wet, he will be unable to fly. In the reboot, he is redesigned to resemble a humanoid blue dragonfly.
- 40. A Petrosapien from the planet Petropia. He can manipulate his crystal physiology at will, allowing him to create crystal weapons, projectiles, and defensive structures. However, his body is vulnerable to powerful sonic vibrations, which can cause it to fracture.
- 44. An unidentified mole-like alien from an unidentified planet. He has a prehensile mustache that can act as fists and enables him to fly by spinning like a helicopter.
- 46. A Nemuina, a fairy-like alien from the planet Nemuinos IV. He can fly and generate dust that enables him to put others to sleep and manipulate dreams.
- 47. A Geochelone Aerios, a turtle-like alien from the planet Aldabra. He has the ability to retract his head into his shell, where an opening in the shell serves as a viewfinder; in this state, he can blow wind from the holes in its shell while also using his arms as propellers.
- 50. A Microchip that was uniquely created by the Omnitrix. Unlike other Microchips, he has a humanoid, insect-like body due to being half-human and half-microchip. He can shrink to microscopic sizes and generate energy blasts from his eyes and hands.
- 52. A Fulmini, an energy-based alien from the destroyed planet Fulmas. He can generate and manipulate electricity. His presence in the Omnitrix influences the other Omnitrix aliens and gives them additional electricity-based abilities similar to his.
- 53. A Galvan, a small frog-like alien from the planet Galvan Prime. He possesses an advanced intellect that allows him to outwit larger enemies, create almost anything from spare parts, and deduce the function of any device at a glance. His size allows him to squeeze into small spaces and climb walls due to tiny suction cups on his skin.
- 54. An Orishan, a mollusc-like alien from the planet Kiusana. He can manipulate pre-existing water, expel it as pressurized blasts, and fly by using water as propulsion.
- 55. A Galvanic Mechamorph, a race that was accidentally created by Galvan scientists who tried to make Galvan B (their planet Galvan Prime's moon) habitable by binding self-replicating nanotechnology to Galvan B's minerals. When a new sentient species was born as a result, the Galvans abandoned the project and allowed the Galvanic Mechamorphs to flourish on their own. Other than firing plasma beams from its eye, a Galvanic Mechamorph's primary ability is to merge with technology, upgrading or changing it far beyond its original design. While they can control non-sentient machines, Galvanic Mechamorphs are incapable of properly controlling sentient technology. Galvanic Mechomorphs are also vulnerable to electricity and any substance corrosive to regular metals, both of which can damage their delicate innards.
- 64. A Kineceleran, a raptor-like alien from the planet Kinet. He can manipulate his own friction to move faster than lightning, climb up walls, run on water, easily come to a dead stop on most surfaces, and create tornadoes by running in a small circle or spinning.
