Idealism and government rarely mix - and this is just as true for teams of superheroes as in more mundane matters! The Second Chance Squad was formed for all the right reasons - people with exceptional capabilities brought together by a visionary leader to put those skills to good use - and naturally tensions arise between what they think they ought to be doing and government policy and directions.
The group is designed along the familiar lines of one formed of people with specific abilities and used to deal with specific problems. With talents as varied as fast driving and flying, archaeology, physics and a talking gorilla one challenge is going to be coming up with appropriate challenges for them. Still one use for the group as a whole is to use them as government troubleshooters, possibly sticking their noses in when your party really doesn't want the government looking over their shoulders!
Each member of the group is given a full write-up including stat block, background and 'adventure seeds' for use if you want to introduce them into your game as individuals rather than a team. Of course, that doesn't preclude the rest of the team turning up later once your characters have got embroiled with one individual member... in fact, that could prove most effective particularly given their government involvement.
Alternatively, if you enjoy the conflict between governmental and idealistic aims and the use of skilled yet diverse teams, you might wish to consider using them as player-characters and make them the focus of your adventures as they pick their way through ethical issues as well as the challenges you provide for them in terms of villains to combat and mysterious events to figure out. That could be fun too...
A neat group worth a look.
