5x15 - Dragon Ball Z: Dragon Box

No matter how much Cell keeps attacking, Gohan refuses to fight back in earnest. No. 16 takes Cell by surprise, pins him with a full-nelson, and is about to blow himself up. However, Bulma had removed his self-destruct device. After destroying No. 16, Cell produces a number of Cell Juniors, and sends them to battle the other Z Warriors looking on, in order to give Gohan no choice but to fight!
