Well, not ‘meet' per se. You (and the rest of the world's populace, including those obscure tribes in the Amazon that cruise about in their look at my wang, waving merrily in the wind as nature intended loincloths shooting monkeys in the ass with poisoned darts) surely witnessed these two guys' antics in The Dark Knight/The Dark Knight Rises/previous Arkham installments. They are, as wacky funster Will Ferrell once -almost- said, kind of a big effin' deal.
So, too, is the fact that they both seem to be reprising their respective roles of watching the world burn and rasping incoherently from behind a Hannibal Lecter-esque mask in Batman: Arkham Origins. As IGN reports, a recent promotional standee for the game shows surreptitious, lurking-in-the-background images of Bane and the Joker, which goddamn close to confirms that they'll feature in Origins. As one of the aforementioned eight assassins hired to murderize Batman? As another element of the plot? A cameo appearance? We don't yet know.
What we do know is that you want another snark-tacular look at just who these guys are, for those deficient in their comic book knowledge. Which you can find by raising your eyes gallery-wards. We saw Black Mask and Deathstroke in the last installment, join us next time for Scarecrow and Killer Croc, both of whom also appeared in IGN's exposé.
