I love, love the new Captain Britain, Dr. Faiza Hussain (aka Excalibur). A superhero who actually works to help people, who has healing powers and goes out of her way not to injure anyone! Her al-amira and white lab coat give her a very medieval look to go with her magic sword — which she picked because given the traditional choice between the Sword of Might and the Amulet of Right, as a surgeon she wanted something to cut with.
She was absolutely great in the War World two-parter Captain Britain and the Mighty Defenders, drawn by my favorite penciller and definitive Captain Britain artist Alan Davis. I hope Marvel keeps using her. It would be great to see her teamed up or played off against their other mystical magical surgeon, Doctor Strange — who currently has some very nasty things inside of him.
