Interesting... If its base Maelstrom before he killed Anomaly and became a cosmic entity.. .then yes... maybe 7-8/10..
if its maelstrom after that? i'd say maybe... 5-5.5 out of 10... seeing as Hal beat the living snot out of sinestro before.. and is probably one of the few gls to be able to say that...
but quasar barely beat maelstrom before... he'd do it with hals help.
I was going for the maelstrom after he got all upgraded. and sinestro didn't really get beaten by hal. Sinestro let hal win, so that he could corrupt OA. So I dont know about that one. Sinestro can give Superman or Thor Fits. It would be intersting if Hal Fought Maelstrom, and Quasar Fought Sinestro. Sinestro is actually the greatest Gl ever. And since he's been evil, he doesn't have those limits as to what he will and wont' do with his ring. I wonder what things each team could come up with to pull a win.
