I've always liked the Black Panther, but the current "urban vigilante" era at the hands of David Liss, Francesco Francavilla and others is one of my favorites. This Panther is just really cool looking. I know he's supposed to be some kind of genius, but he's always been a hand-to-hand combatant to me, so putting him in this SWAT-inspired combat gear is a no-brainer.
