one might say you cannot mix science with magic,but in Screamer case. She has done great thing with her powers and know how(or so she says). Screamer has invented a way to extract energy from anything living,such as:robots,humans(any living being). Even a Planet,Earth most the time. It can be very painful to the one she is draining.
It takes just a touch from her loving hands to drain one dry,so in the heat of battle keep your distance. Many have tried to get information out of her on how she does this, but have not lived long enough to tell.
Well working on one of her experiments(to give her more power) , some how backfired on her. Turning her into what one would call a Robot Vampire. She does enjoy a good drink.
First she'll drain the energy and then before the last bit of energy is gone,she'll cut thier throat and take a drink(Aaaaaahhh good to the last drop!) Her main concern is power and control. And if you ever meet her dont let her beauty fool you, looks can always be deceiving.
Screamer was a very young child when her mother and father were destroyed. For a crime they did not commit,they were branded traitors and executed. A mob of Autobots were at fault, and till this day Screamer will not reat till every last one of them has been destroyed.
Thanks to the horror of her childhood she sometimes gets very emotionally depressed,this can cause her to shut down for weeks at a time. Because of her being so overconfident, it may someday lead to her demise.
