Ditto

Ditto (voiced by Rob Paulsen in a voice resembling that of Yakko from Animaniacs) is a Splixson (based on the word "split") from the Earth-like Planet Hathor (the name of an egyptian goddess)

Ben first transforms into Ditto in Divided We Stand.

Abilities
Ditto is a small, humanoid alien with the ability to clone himself without limit. Every clone operates independently, regardless of whether or not Ben wants them to, and each clone is indistinguishable from the others. Though the clones are autonomous, they share each other's pain, and the death of one clone will cause the death of the rest (as seen with Dr. Animo's Ditto-enhanced Stinkfly mutants) which negates the usefulness of making large numbers of clones. The child-size Ditto is also no stronger or faster than his size and build suggests.

Weakness
All of the clones share a link with each other, making it so that when a clone is hurt, the other clones feel its pain. Also, if one clone is killed, the others are automatically destroyed as well, thus negating the ability to form many clones.

All of the clones are no stronger or faster then their appearance suggests.

If one of the clones is separated from the others by a great distance, then when the Omnitrix times out, the wearer will not transform back into normal, or be able to become another alien until all the clones are brought back into one.

Planet
The planet Hathor is home to a race called Splixsons who have not grown out of Mitosis (that is how they can divide without limit), but they don't fight or start wars at all (that was made clear in Divided We Stand) because of this they are more peaceful than other races and they tend to be farmers or painters because of it.

Ultimate Alien
Ditto has changed with more black on his chest and bottom body. The Omnitrix symbol has also moved from his forhead to his chest
