Superhero Team

Once we have enough superhero peeps, what sounds like the most fun way to make a superhero team?

KK team name ideas:

The Defenders (could be of America, of the Earth or no tag for all these)
Earth's Advocates
Guardians of Justice
The Protectorates

I guess it really depends on their origin and their goals, actually. If they are trying to protect people then the above stuff would work but if their goals are trying to like hunt down enemies and stuff they could be something like...
Agents of Order
Other things also
