What’s exciting about the new Wolverine solo movie Logan is how dark and creepy it looks compared to the superhero movies that have come before. It’s definitely a more mature turn from our favorite curmudgeonly X-Man, where danger and death are a lot closer and more realistic than they used to be. Giving his all to the creepy-factor is Stephen Merchant, whose albino Caliban we’ve seen in two photos already, and who looks a little different from the version of the character we saw in this summer’s X-Men: Apocalypse. Now, a third Caliban photo has been revealed, this one possibly odder than the last.

The founder of Latino Review Kellvin Chavez tweeted this new photo, which has a distinctly untrustworthy-post-apocalyptic-surgeon feel to it. That’s probably not the kind of thing Caliban will be doing, though.

For those of you who may not know, Caliban has two abilities: he can psionically detect any mutants nearby — which will probably come in useful for Wolverine’s purposes — and he can also use anyone’s fears against them by absorbing their psionic energy. He also has incredibly light-sensitive eyes, which is probably the reason for those neat goggles.

From these photos, it looks like we’ll meet Caliban in Morlock form, where he still looks like a regular human (just really really pale). Long story short, the Morlocks are a group of mutants whose disfigured and strange appearances make it impossible for them to live comfortably in aboveground society, so they form a society of their own down in the sewers. Caliban has been recruited by a few different people in the comics to help them find mutants using his tracking abilities, so that’s probably going to be his purpose in Logan — finding missing mutants in a future where they barely exist. In this summer’s X-Men: Apocalypse, Apocalypse himself uses him to hunt mutants down and kill them, but hopefully he’ll have a less sinister role in Logan. Caliban is a bit of a wild card, working for or against the X-Men depending on whoever his boss is.

Logan hits theaters March 3, 2017.
