Who destroyed Genos?
Genos was destroyed by the Deep Sea King.
However, since Genos is a cyborg, irrespective of the quantum of damage he suffers, as long as his core is linked to his brain, he can replace damaged parts.
As we saw with his fight with the Deep Sea King, Genos was extremely damaged; Genos’ hands and legs were literally destroyed in the fight, but because his core was still linked with the brain, scientist Dr. Kuseno was able to rebuild him.
