Best: The Phantasm (Batman: Mask of the Phantasm)
Voiced by: Stacy Keach
If you haven't seen Batman: Mask of the Phantasm, the big-screen adventure existing in the same universe as the popular 90's animated series, then add it to your Dark Knight Rises inspired marathon. Animated or not, it's honestly just as dope as the Chris Nolan flicks.
It features an original villain, The Phantasm, who keeps his appearance pretty simple unlike most Bat rogues, and actually succeeds where most of them fail at appearing intimidating. A little bit of A$AP Rocky goth-ninja steez, mixed with a ghoulish mask and that gnarly scythe-hand? Yea, this is easily the scariest Batman villain to grace the screen.
