  == Bio means life or living!! ==  Cell isn't mechanical or not completely mechanical. Notice that he has living tissue. (example) During the battle with Gohan, he is blasted by an enormous Kamehameha Wave. as a result he loses a few limbs, and starts to BLEED! MACHINES DON'T BLEED!! This is proof that he is more than a simple Jinzoningen! Also notice that #16-#20 don't regenerate! while cell is the only Jinzoningen that does, besides Coola if he even counts!
