I'll get to work on something.
And here we go:
Name: Angel Ashcroft
Species: Android
Gender: Female
Age: 16 (mentally; activated 1 year ago)
Appearance:
Angel has straight blonde hair down to around chin length at the longest, and bright electric blue eyes. Her body is, for the most part, clearly artificial, with visible doll-like joints at the shoulders, elbows, wrists, hips, knees, and ankles. She always appears to be wearing a skintight bodysuit and thigh-length socks, but the simple truth is that her body's outer covering is patterned that way, only having a skin-like coloration in some places. She usually wears a black ribbon in her hair, and is fond of outfits with long sleeves and skirts to better conceal her joints. Her superhero costume consists of additional armor and equipment worn over her base body.
History:
Angel is a combat android created by the government in response to the growing number of superhuman criminals. The purpose of the project which created her was to produce a reliable, modular machine capable of enforcing the law and engaging super powered foes with greater effectiveness than the typical military. She represents some of the greatest advances in robotics and weapons technology developed in the past several years. She also has the appearance and base personality of her project lead's late daughter.
Angel was first activated a year ago, and has undergone a rigorous program of tests of her hardware and programming, training, and education. She has been sent to the school as a way to further her education, with a notable hope that she will acquire a greater sens of human empathy and understanding of human behavior. Her government sponsors also feel she may be useful as a mole, and have instructed her to keep tabs on the other students and report her observations periodically.
Items: A flight pack, additional armoring, a specially-made energy weapon, a repair kit and spare parts.
Powers:
As a machine, Angel does not need to eat, sleep, or breathe. Poisons and other agents that affect living things will also obviously have no effect on her. Her construction renders her much stronger and tougher than a person would be. She can rapidly process information and has near-perfect memory. She's skilled in mechanical repairs and hacking computers. rather than own a smartphone, she has a similar communications system and wireless internet access built in.
Weaknesses:
Angel does not heal injury naturally, and must instead be repaired. She can do this herself, if she's in any condition to do so, or at least try to walk someone else through it. EMPs can do anything from briefly stun her to completely incapacitate her for some time, depending on the overall strength of the pulse. Similarly, electrical attacks can also more easily damage her more delicate components. She can be hacked or reprogrammed.
