Superman,Wonder Woman & Captain Marvel vs Firestorm,Atom & Ry’lor

Three DC Characters vs Two DC Characters and one Marvel Character who wins

The fight takes place in Deathvalley who wins

Ry'lor- http://www.marvunapp.com/Appendix/rylorxfo.htm

I'd have to say the first team. Ry'lor looks tough but Firestorm will get taken out easily and then it will be 3 on 2. Odds favor Supes, WW, and Marvel.

This is the firestorm I was talking about.
