Yo i like that, and i wanna see more of stuff like that. For me, this could be like Lobo all over again: I gave next to no shits for that guy and thought he'd be a lame dude with Scorpion's spear or something, then his gameplay was shown and he looked like a genuinely fun character. If Batty plays like a BAMF, then I'll change from "no me gusta" to "me really really gusta".
I'm personally expecting her to have more bat tools in her arsenal, since Bruce n Dick only use like, a few in their entire move-set. I can totally see her using a Sonic Battarang similar to Jax's ground pound (not unblockable obviously, maybe unblockable as meter burn?) for space control, having an obvious karate attack like bat people should have (maybe a command grab takedown? Iono, I just love scooping fools), and some kinda rush punch attack (LBSH, it'd be hype if she just runs at a dude and goes nuts on them).
I'd also like this as an alt, as it'd confirm her for the most attractive female in the game
