I am a big fan of Mantis, so I look forward to her showing up in the current Guardians book.
I chose the Psylocke head to try and give her an Asian appearance. The buttons and trim, boots and hair band were sculpted with Apoxy Sculpt. I thought of adding some wrist articulation to the gloved hands but decided against it (due to laziness?).

Head: Toybiz Psylocke
Upper torso: Hope Summers

Jacket bottom: random jacket from fodder box
