Pretty certain Asura takes this. However if he's in his wrath form (is that what was meant by rage form :0? Just curious since Asura has some forms that could make this a stomp in my opinion) that inflicts damage on himself, if Goku could hang in there I figure he could win...but Asura is by no means a push over..I am trying everything I can think of to help Goku but Asura is rediculous...his win over Wyzen in his Gongen form I feel already tips the scales in his favor ._. and that was near the start of the game if memory serves?
By Azura, by Azura, by Azura! It's the Grand Champion! Standing here! Molesting me!
