@dbs_10_10 Neither, he would have kept getting stronger because of his regenerative abilities and saiyan cells in him, so if they didn't figure out how to beat him and if krillin had destroyed 18, he would have achieved his final form anyways
@dbs_10_10 Cell would have achieved it either way, if 18 got blown up, then Cell would have achieved differently but with would have taken much much longer so does it really matter?
