4x25 - Dragon Ball Z: Dragon Box

Cell, having defeated Piccolo without any trouble, begins attacking without mercy in order to absorb No. 17. Not even No. 17's power is able to put a dent in the superior power of Cell. Just as he is about to be swallowed up by the creepy, wide-open orifice at the end of Cell's tail, No. 16, who had shown no inclination to fight up to now, takes action. Saying "the time for me to fight has come," he steps forward to stop Cell!
