Gohan and piccolo were 2 warriors that faced off the terrifying cell max! And once the dust cleared earth was safe again and then Gohan and piccolo were training after 4 months and they seem to bump into you....

Piccolo: well I hope your not trying to fight.

Gohan: (turns to ultimate/mystic form)

Piccolo: turns orange form: don't try us kid.
