MR's first moveset (... unless I forgot 'bout a previous one?). I approve.
To be honest, I'd of preferred if Bruce's Down-B would'a been Explosive Gel (Snake would be proud), since that smoke pellet is kinda underwhelming. Perhaps his Side-B could use a gadget not the Batclaw?
If his Side-B does change from the Batclaw, here's a unique idea. He could have a way to use a physical grab and the batclaw interchangeably since Batman's never been afraid of gettin' up close and personal with some martial arts badassery. Like pressin' B at the same time as grab let's 'em use his "special" grab, i.e. grabbing with the Batclaw to reel 'em in. Grabbing without the extra input is just his standard close-range grab. It would also be used as a tether recovery (air dodge + z) instead of taking up his Side-B move.
