Castle (Nathan Fillion) and Beckett (Stana Katic) have dealt with a lot of different criminals through the years, but on this Monday's episode, they have a very unique threat to face: a superhero!
The episode involves Castle and Beckett investigating the murder of an ex-con, which leads to a bona fide costumed vigilante - one who may be a real life superhero.
IGN has an exclusive promo video for the episode, which features a special comic book visual touch. Check it out below!
This episode, "Heroes and Villains" will also feature a tie-in with the Castle comic book coming next week from Marvel, written by Brian Michael Bendis.
