Ditto is the Omnitrix's DNA sample of a Splixson from the planet Hathor.
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.
Powers and Abilities
Ditto has the power to duplicate itself without limit and with any number he desires. For instance, he creates a clone of himself when he was attacked by Dr. Animo's mutant seagull in the beach. The clones can also be created when Ditto himself is in danger so as to better save himself from certain danger. One weakness he has at first, is that if one of the clones dies, then all of them will die. In Ben 10: Omniverse, this was changed if the original clone were to die instead. Also being able to duplicate, if one of the clones are feel pain then it is transmitted to the other clones and thus will feel fain as well.
