Behemoth (DC)
From Multiversal Omnipedia
Behemoth, real first name Terri, was a student at the Themyscira School for Girls who was affected by the genetic spark, gradually turning into a super-strong purple creature. She was recruited by the Know Man (along with other sparkers like Onyx and Unity) to battle the reformed Justice League of America. Like the others, she was knocked out by an angry Martian Manhunter. Presumably, she was restored to normal after the genetic spark was dispelled.
