Featuring the following heroine!

Siryn

Real name: Theresa Cassidy
AKA: Terry. Red.

First appearance: Spider-Woman 37

Favorite quote: "I reckon a collapsin' buildin' will keep him occupied f'r a while!" (Deadpool 3, after rescuing Wade Wilson by bringing the house down on her buddy the Juggernaut)

Team affiliation: Occasional X-Men hanger on, but more permanently with X-Force. The daughter of Generation X's trainer Sean Cassidy, AKA Banshee, Theresa was raised by Black Tom Cassidy after the death of her mother. For a while she joined him and his close friend the Juggernaut in their criminal pursuits. Personal gain just wasn't in her make-up, however; despite her strong emotional ties to both men, Siryn now fights against them when she must.

Powers: Like her dad, Theresa possesses an ear-splitting sonic scream, the compressive force of which aids her flight and can be used as an offensive weapon. She manages to talk and scream at the same time, which defies all logic (all I can figure is that she has two throats).

Favorite storyline: X-Force 31, where Terry begins to put her life together by confronting her "Uncle" Tom, as well as the demons of her past that led to her drinking problem.

Least favorite storyline: The Muir Island saga. Incoherent mess that existed just so a bunch of mutants could fight each other, and the start of the downhill slide for several of the Mutant books.
Weirdest match-up yet: Yep, it looks like Warpath and Siryn are quits, leaving the ruthless mercenary Deadpool with the keys to Theresa's heart. Where is this relationship heading? With Typhoid Mary now in the mix, anything could happen!
