Ditto is the Omnitrix's DNA sample of a Splixson from Hathor.
Ditto is a humanoid alien about the size of a small kid. He has white skin and a black and white head with three green fins and two small spikes on each cheek. He wears a green/black overall-like outfit. He has two green gems on each arm and three on his waist. The Omnitrix is on his forehead.
- Ditto can create limitless clones of himself.
- He is very flexible.
- He can breath underwater.
Ditto and his clones are linked so they share each others physical pain. If one Ditto gets hurt the others feel the same pain. If the original Ditto is defeated, the other Ditto clones will automatically be defeated too which is why making an army of clones isn't a good idea.
