Ditto

Ditto is the Omnitrix's DNA sample of a Splixson from the planet Hathor.

Appearance
Ditto is about the height of an average human child. He has white skin, a black and white head, white face, along with black shoulders. Ditto’s hands are large with 4 digits and his feet are merely stubs. He has 3 fin-like growths on their head. Ditto also has gem-like orbs on his arms and 3 button-like gems on his waist. Ditto's clothes are black and have an overall-like design. Ditto wears the Omnitrix symbol on his forehead in the original series.

In Ultimate Alien, the white section outlining the hourglass symbol across his chest and on his arms is now blue. Ditto wears the Ultimatrix symbol on his chest.

In Omniverse, 11 year-old Ditto's fins on his head are white and the ones on the side are connected to his eyes. He also has two small whiskers on each of his cheeks. His fingers are now sharper and the green orbs on his shoulders are gone. He has gems like the three on his waist on his shoulders and wrists. His neck is completely black. He also seems smaller and stubbier. The feet of his suit also cut off to reveal 3 cat-like toes on each foot.

16 year old Ditto looks similar to his 11 year old self, except he has green fins rather than white, and his jumpsuit is now green with black patches under his arms, green sleeves, and black ankles. This jumpsuit also seems to have a design based on the Omnitrix symbol with black triangles on the shoulders and green in the center. The three gems on his waist are now on a black belt.

Powers and Abilities
Ditto has the ability to clone himself with no limit. While it is like actually splitting in half in the Original Series, in Omniverse, it is similar to Echo Echo, able to split and remerge at a fast pace.

Every Ditto operates independently, regardless of what the others wants them to do and each clone is indistinguishable from the others.

The raised green bumps on Ditto's body are sensor nodes, which help create a sensory web around the Ditto clones. This sensory web allows the clones to share in senses and physical sensations.

Ditto is more flexible than a human.

Ditto can breathe underwater.

Ditto can jump surprisingly high for his size as shown in Divided We Stand, while playing basketball, he slam dunked the ball on a hoop that would be difficult for a average human to jump high enough to do.

Weaknesses
Ditto's clones share a link with each other, making it so that when one Ditto is hurt, all the others feel the same pain.

If one Ditto is killed, the clones are automatically killed as well, thus negating the ability to form an army of clones.

But, In Omniverse, Ditto's weaknesses are now removed, as seen in Oh Mother Where Art Thou, The Dittos don't share a link anymore

Trivia

 * According to himself, Ditto is not fast or strong.
 * Ditto seems to be a homage to the Warners from Animaniacs, having an iconic voice actor, similar mannerisms and similar color layout.
 * Ditto's voice actor is that of Yakko's from the television series Animaniacs and Raphael’s from the 1980s television series “Teenage Mutant Ninja Turtles”.
 * If the Omnitrix times out while Ditto is split into multiple clones, the Omnitrix will try to pull the clones together into one Ditto before reverting Ben back to his human form. If unsuccessful, it will not time out.
 * After Ben is brought back together, the Omnitrix will be short on energy and transformation sequences will be much shorter for a time afterwards.
 * In Hot Stretch, Ben says that, according to his fansite, Ditto is his cutest alien.
