Gender: Male Location: Planning to take over the WORLD!
dc handily unless wendel is able to manipulate the ring energy. NOT an impossibility imo, but not likely. i'd give dc 7/10, and each would be a fair to midling beating. the losses are due to quasar mucking with their energy and giving marvel the edge.
Don't forget BFR isn't off. Quasar can actually attempt to BFR them into the Q-zone for an instant win.
I don't think Sinestro is physically strong enough to pull a Gladiator on Quasar. Attrocitus may, but since he has no experience with Quasar and his powerset, he could be taken off guard and BFRed too.
