His name is Cell. He was spawned by Dr. Gero's computer and he came here to absorb the two of you. If he succeeds, and he's able to integrate you and Android 18 into his being, his evolution will be complete.
Rejoice my brother and sister. The three of us are like pieces to a puzzle, designed and destined to fit together and form one whole. Unite with me and fulfill Dr. Gero's dream to create the ultimate warrior.
