If we don't go with this theme I will make sure it is added to the Create Hero Villain Link thread for further consideration.
Also re your colour lists some more information on ones we have not done would help.
According to Wikipedia Corvids include Jackdaws, Magpies, Rooks, Jays. Treepies, Choughs, Crows, Ravens and Nutcrackers.
The most independent member of the group comes from Switzerland and is the latest person to claim the name of Magpie. She is a jewel robber of some repute robbing people and places of some of the finest jewels in the world. She likes to keep what she steals and is entranced by pieces of exquisite beauty and craftsmanship. This means she is not that interested in what the team wants to do if the opportunity for something shiny and above all portable comes up. She has an expensive (and surprisingly durable) feather wing costune that mimics the bird after which she is named. She knows some martial arts but is more a scout and spy rather than a combatant.
