The Red Devils of Gayland
They are based on the Ninja dial from the Batman: The Animated Series Heroclix set (a figure I probably wouldn't use much, if at all; not a ninja fan). It's an easy fit with sneaky acrobats.
A similarly easy fit was the sculpt: Daredevil, of course:
|Plenty of those to go around.|
This foursome of Red Devils probably aren't enough to go up against a Green Arrow team by themselves, but they are a perfect 100 point plus-up to a team built around a more serious threat. Like... um.... the Octopus? Sure; the Octopus.
