Siren(bio tweaked)

Name: Siren(Alice Balinsworth)  
Species: Tulvan(Variation of the late human race)
Appearance: Siren has bright, blue hair that doesn't follow any particular order, and hangs to her shoulders in a mess of spikes. Accompanying her hair are red irises. She is somewhat tanned (due to her home planet's dry, hot climate) and is built thin, with slightly above average muscle, standing at five feet and ten inches. 
Attitude: Her mood can change dramatically, but she is generally untrusting and serious.
Gadgets/Weapons: A weapon that has the appearance of a revolver, but generates and fires bullets made of light fused into a solid, or hard light. She has a vortex manipulator that often sends her rather off course, so it's more of a last resort.
Clothing/armor: Siren wears a heavy, dark grey cloak that has a hood. This hood usually does a decent job of concealing the majority of her face, but she also wears a mask made of smooth gold metal. The only features on it are two faintly glowing, blue circles where her eyes would be. Due to the cloak, her shirt isn't visible, so I won't include it here. The pants she's wearing are black jeans, simple, human-made. On one arm is a heavy gauntlet that's a coppery/brass-ish color. It has a vortex manipulator built into it. It also has a component within that generates a surge of plasma, which is contained by a small, weak forcefield. Humans would refer to it as a plasma sword or energy blade, or whatever the popular sci-if genre dictates. Anyways, this component creates a foot long blade of plasma from the top of the gauntlet forearm. On Siren's other arm is a clockwork wristwatch, but it's of Tulvan design, and shows Tulvan numerals. She has knee-pads made of the same alloy her mask is, and black toe-shoes.
Back Story: Siren used to live in the razed wasteland of the planet Tulva, where war was a constant and simple supplies like food and water were extremely scarce. After scavenging ruins and killing raiders for most of her life, she was saved by a passing shuttle. However, the price was acting as a bodyguard for the owners of this shuttle. Siren did work for them for some time, but payed them off to let her leave after another two years. Siren was twenty-seven now, and after traveling for some time, became a vigilante assassin. No matter where she went, blood seemed to follow. She is now in hiding on Earth from te multitude of enemies made.
Interesting Quirks: Despite a bloody history, Siren is fairly happy. She is often considered the type who enjoys killing. This, of course, isn't true.
