Steve
Steve is pretty good in an extended crisis. He's adapted well, but is very much still in the mind set of 'when and how are we going home'. He does not see this as a permanent solution.
Given that they are one...space nation now, he doesn't really do the 'Captain America' thing, not that he was before space, that was Jasper, but he definitely is involved in a motivational and political level, making sure life carries on and people are good and justice, etc. He probably has little campaigns about littering and conversing and stuff. He's old.
