Ditto

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

Appearance
Ditto is about the height of a human child. He has white skin, a black 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 crater like things on his waist.

Ditto's clothes are black and have an overall-like design. Ditto wore the Omnitrix symbol on his forehead in the original series. Ditto wears the Ultimatrix symbol on his chest in Ultimate Alien.

Powers and Abilities
Ditto has the ability to clone himself without limit.

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

Ditto and his clones are all linked, which allows them to share each other’s physical sensations.

Ditto is more flexible than a human.

Ditto can breathe underwater.

He also has super agility.

Weaknesses
Ditto's clones share a link with each other, making it so that when a clone is hurt, the other clones feel the same pain. If one clone is killed, the others are automatically killed as well, thus negating the ability to form an army of clones.

While cloning, Ditto is vulnerable to attack.

Trivia

 * Ditto seems to be an homage to the Warners from Animaniacs, having an iconic voice actor, similar mannerisms and similar color layout.
 * According to Ditto, he is not fast or strong.
 * Echo Echo proves to be a much more efficient choice than Ditto because he is the more enhanced version of a duplicating alien with it being more powerful and a handful to defeat.
 * Ditto is the second alien with the ability to duplicate himself. The first was Buzzshock and the third was Echo Echo.
 * Ditto's voice is that of Yakko's from the television series Animaniacs and Raphael’s from the 1980’s 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. If unsuccessful, it will not time out.
