The Brave & The Bold
There are several interesting sub-teamups within the fighting groups. Vixen, Vibe, and Steel II are all seen fighting close to each other - they were members of the "Detroit Justice League" in the comics. And the Shining Knight and Vigilante team up - in the comics, they're both members of the Seven Soldiers of Victory (and S.T.R.I.P.E, who was a member as Stripesy, later joins them, as does Stargirl, filling in for the Star-Spangled Kid). Green Arrow and Crimson Avenger also fight side-by-side - they were members of the Seven Soldiers as well (pre-Crisis).
