Superhero Proving Grounds

Though hard to believe at first glance, Tetra was once a regular human. She used to be a member of a criminal organization known for organizing several illegal fight-tournaments, many of which featured her as their undefeated champion. Every arena she stepped into was coated red with blood There were few who managed to land a hit on her... and even fewer who managed to best her in battle.

In fact, rumors say the only person to ever come close to beating her in a fight had to rely on dark magic to put up a decent fight, magic which would end up back-firing on the unfortunate magician by giving her the extra pair of arms she's now known for.

Abilities: Given her extra apendages, Tetra has a unique form of super-strength. Each of her arms is approximately twice as strong as a professional boxer, but using all four in tandem gives her the crushing force of a crocodile's bite.
