We now know whom Ryan Reynold’s Deadpool will battle in the sequel to last year’s shock R-rated hit.

Jack Kesy — of FX’s The Strain and the upcoming big screen Baywatch reboot — has been signed to appear in the movie in a role that might be obscure to even the most ardent Marvel Comics fans: Black Tom Cassidy, Deadline reports.

Black Tom debuted in 1976’s Uncanny X-Men #101, where he proved just how willing to engage in racial stereotypes comic books were back in the day. Not only was Cassidy an Irish supervillain who not only used his ability to project energy through plant life by shooting people with a shillelagh but he also lived in a castle populated by leprechauns. If this is the version of the character that’s going to appear in the second Deadpool movie, then… actually, that would almost make sense, considering the the first one’s off-color brand of humor.

There are, actually, a couple of comic book connections between Cassidy (a relatively obscure bad guy in the comics) and Deadpool. For one thing, Black Tom has faced off against Deadpool a couple of times in the past, most notably in a 1990s storyline where he needed ‘Pool’s mutated DNA to prevent his own powers running amok.

More importantly, the comic book Cassidy was the surrogate father of Siryn, a superhero who also happened to be the longterm love interest of Deadpool throughout the latter '90s. Now, the movie Deadpool has his own main squeeze in the shape of Morena Baccarin’s Vanessa but who’s to say Cassidy couldn’t show up in some other way?

Also featuring Josh Brolin as Cable, Deadpool 2—to be directed by John Wick’s David Leitch—will be released June 1 next year.
