This is a weird battle :/
goku as a boy had laerened a move from granpa gohan that would double his speed and stragth for punches kicks chop slashs and a poke between the eyes still a great fighter though goku wins fight because when you face goku agisnst an oppenent he dosnt always start as strong but by the end of the batltle he his thats part of being a sayian
