Silver Surfer - Odin already Punked him with a single blast
Gladiator - Seeing Surfer go down in one hit really isn't going to do much for his confidence
Superman - Magic + Supes = Dead
GL (Hal) - Dies
Flash - Dies
GL (Alan) - Dies
GL (Kyle) - Dies
Martian Manhunter - Burnt to death
Captain Atom - Suit torn open
Captain Marvel (Shazam) - Beaten to death
Orion - Dies
i actually give the astro-force the ONLY chance to do some damage. thanos from all appearance did essentially NO damage to him. ss may arguably be the most powerful on this team and he was basically one-shotted. now at one time it seemed the avengers gave zeus a little trouble, and that team was far weaker than this one, but odin is depicted more consistently than zeus and generally more powerfully.
sentinel, i don't know too much about, but if he's as powerful as i've heard some claim, he may be the truly legimate threat in this thing. the team's best bet is to give the rings away to someone else -- maybe orion or captain marvel. even still, i don't see the team pulling it off.
After seeing the trouble that Superboy Prime gave the D.C. universe and the rather pitiful showing that the Surfer displayed against Odin, I'm heavily leaning towards Odin. Leo makes a good point that the team's chances seem to be in the Astro-force and in Alan, but still it's hard to go against Odin when a combined attack from Thanos and the Surfer couldn't even scratch him. 😬
