Banshee

Theresa Cassidy, daughter of the original Banshee, adopted her late father's codename in honor of Sean Cassidy's legacy. A mutant sonic screamer and longtime X-Factor member, she carries on the Banshee name while continuing to serve alongside her teammates in the mutant community.

Meet Banshee, a Modern Age Marvel creation who made their debut in the 2010 crossover tie-in X-Men: Second Coming – Revelations, brought to life by Simon Spurrier, Paul Davidson, and Francis Portela. This is a character forged in the thick of Marvel's mutant universe, sharing pages with a compelling roster that includes Longshot, M, Monet St. Croix, Theresa Cassidy, and Strong Guy — serious X-Factor company by any measure. Most of Banshee's catalog presence is rooted in X-Factor and its related volumes, including the celebrated Peter David Omnibus, making this a character for readers who love the grittier, character-driven corner of Marvel's mutant world. Thirteen appearances may be a compact legacy, but every one of them lands in some genuinely worthwhile comics real estate.
