To me it's Natsu Dragneel from Fairy Tail, but to be honest and fair it will have to be Erza Scarlet from FT :) She is like the most strongest, most toughest, offensive female 日本动漫 character ever! ^.^ That's what I think Everyone fears her epescially Natsu and Gray ^-^
the most powerfull of all is Brolly (the legendary super saiyan)- dbz even 悟空 needed all the strength of his 老友记 to defeat him....................heh heh heh
