What are some good names?

In my comic the main characture is a girl who is half robot, but the only thing that looks robot is her eye -- which is a triangle for and iris with the dots around the sides -- her arm -- that covered with gauz -- an a few plugs here and there. She was a marine in the army and also a member in one of the most ruthless gangs on her planit. The military put her in prision because she was lesrning too fast and they didnt want her to learn all there weaknesses and thake down the Gov. The prision she went to is mainly guys and everyone of them is scaired to cross her path. Shes a total bad*** with guns and knives and she smokes. :P. The names that i came up with are Iris, Echo, and Jackle -- but i think jackle will be her last name.
