Yamcha... Spirit Ball+Kamehameha+Wolf Fang Fist=Luffy gets pwnd. xD
"vegeta was a planet buster with a powerlevel of 18,000 krillens power was 37,000 during the freeza fight. krillens not that much stronger then yamcha. his power level has to be in the high 20,000 to low 30,000.
I dont think Yamcha can destory a planet."
