Erebus: i havent thought of a backstory yet, but he is powerful, she has a limited but lasting supply of Bio-hazardous liquid that can be fired from his arm. if he does run out of liquid, he can fire bursts of radioactive energy from her eye. one thing to note, the tanks she has is also her health until he discards it, but his core is more of a glass cannon, should she shouldn't be troublesome in that phase. thats all you need to know
