He was created as a experiment and contains the DNA of most of the Z Warriors, giving him the ability to use the same attacks that they use and much more. One of the biggest advantage he has is the ability to regenerate himself as well as absorbing energy from others using a long tail. Cell has three stages that he can transform into. He did this by absorbing the energy from the other Androids thus becoming the mighty "Perfect Cell."
