Borderlands fan concept: Artifical Siren

Ursula aka artifical Siren aka Seventh aka Object AS-07.
The result of experiments with genetic material of Sirens, first who survive. She was reinforced with implants, mental manipulations and pumped with eridium stuff. Her powers are unstable and dangerous (both for others and for herself). Seventh is as crazy and furious as Krieg the Psyho. When these forces are used, Ursula levitates.
Her Siren's powers include energy tentacles that grab or damaged enemies and can also drain life.
And as usual, she escaped, leaving behind her destruction and mountains of corpses...
