Sinestro/Green Lantern

Strategy
Sinestro Green Lantern is a dangerous card to switch out against unless you're properly prepared. His passive gives him a strong damage boost (similar to Superman Regime) whenever his opponent switches out with a new character. This can be good with special attacks when catching your opponents off guard.

Green Lantern Sinestro's passive can only activate once per his tag-in, unlike other versions of Sinestro. No matter how many times his opponent tags out, he can only gain the boost once until he himself tags out and backs in again, and will gain the boost and his opponent tags out after that.

It should be noted that despite appearances, Green Lantern Sinestro is still a Sinestro character, and will count as Sinestro character for any purpose.
