Twilight Team
No before I get the hate mail on the team name, the team is just called Twilight for short. Why? because in case when all else fails in super hero continuity and the super villains or entity that threatens all that exists this team will come together and wipe them out. they do not meet or have an established base. They only come together when the threat is that dire and they know their powers work well together. This is based on the Marvel Universe, but will do one for DC.
