He's not in loaf with anyone (well Forest but wutevr) i just thought the song tune matches him :3 So his cousin is Aura, and since Aura dies with Arrow, he is the new main villain with Forest. Yes, Forest is one of the new main villains. His story is: When he was younger, was raised by evil parents and siblings. If he did something wrong they'd claw him. He lost part of his leg to his parents, and before he left them, he was stabbed across the middle of his head by his Sister (which his parents didn't mind) so now he has stitches there. He created this green acid where if you touch it, you get infected and become a "Acid Wolf". He runs experiments on his prisoners and basically torturous (if i spelled that right) them for fun. If you've seen Batman vs Superman, he's crazy and shaky like Lex Luther. (also he bleeds the acid that creates Acid Wolves)
