User blog comment:SuperGokuMan/Why Wally West beats Madoka/@comment-27822848-20151222203127

Yeah... no. Gonna take more than a little Infinite Mass Punch to kill Madoka. As for being tagged by Homura, that was because Madoka allowed herself to be tagged, and was baited into it. She would never give Wally that chance.

While Wally is faster, that doesn't change the fact that he can't hurt an abstract concept. Try again.
