Teresia Karisik

Teresia Karisik is a Modern Age Marvel character with ties to both the X-Men and the Hellfire Club — two organizations with sharply opposing agendas — placing her in a fascinatingly ambiguous position within that world.

Stepping out of Chris Claremont and Aaron Lopresti's Excalibur #1 in 2004, Teresia Karisik is a Modern Age Marvel creation whose affiliations tell a fascinatingly complex story — she's connected to both the X-Men and the Hellfire Club, two organizations that rarely pull in the same direction. Over more than two decades of publication, she's kept remarkable company, sharing pages with luminaries like Sage, Wolverine, Ororo Munroe, and Kurt Wagner across titles including New Excalibur and The Uncanny X-Men. With a key issue already to her name and appearances stretching all the way to 2026, Teresia is the kind of quietly enduring character that rewards the dedicated reader who digs beneath the surface of the X-Men's sprawling world.
