There are a lot of silly feats to be said for all of these characters. I would say the fact that Supes and Flash cannot outrun a sanction would mean Sentry and Thor could not either. If it is New 52 Supes I would say it is closer but I just don't think the Marvel team could do it.
I love the New 52 Black Manta. I think that any Aquaman run could potentially run into the light hearted and silly like I thought it used to be. Black Manta is stone cold bad guy that almost makes Aquaman comics grimmer and darker than most other DC comics, IMO. And it works. His origin also leaves some dirt on Aquaman who on the outside appears like a god almost.
