Did Gweyr make it out alright? 

I wouldn't use ninja magneto because either winner will win without much of a fight, as you say, depending on if he tricks her or not rather then us getting a good fight. Even though Evvie's a higher tier she'd likely get demolished, so she's out unless I use the one from my multiverse who's not nerfed. who would in turn crush him and tank all his attacks. Ria from the multiverse is peak human and has a scifi weapon but would likely loose. I'd like to use her for something due to her only, so far, not getting a single hit in anywhere, but against him is not the place.

I'll need to come up with a new character idea that's not such a hard counter as ninja magneto.

On a side note, know the "roast me" meme on Reddit where people post a picture of themselves to get insulted in good fun? I can imagine that for some of my characters taking part in it. XD
