The League generally doesn't kill enemies so absorbing metahuman criminals would be a deal breaker. If he's physically and mentally enhanced plus has abilities like growing longer nails, extra arms, etc... I'd go ahead and make him like a limited Plastic Man or Mr. Fantastic... I do like that the powers come from a metahuman mutation in his DNA!~KL~

Yeah, basically I took the powers from another character I had. I edited out.

The reason he's not similar to 'Plastic Man' or 'Mr. Fantastic' is because he doesn't specifically make himself stretchier, and the way his powers work isn't similar as well. It's kind of like this...:

Sin watched as the baseball flew towards him at supersonic speed. He only had a few minutes to react. Patience...patience.

A beastial growl rose from his throat, and the teen abruptly turned his hand blurring upwards as he stared at the robot who threw the baseball. Behind him, the ball split into two mid-air, falling onto the concrete sidewalk silently, before exploding.

Sin grinned grimly.

His right arm was now...different, if you could even consider it an arm. The entire arm, from the shoulder down, was basically a large, gleaming black, spiky sword made up of some sort of gleaming cold material that seemed to absorb and reflect light. Another baseball was thrown his way. Dashing forward, Sin brought his sword-arm upwards, slicing through the baseball grenade's middle like a knife through butter. His feet abruptly dug into the concrete, and Sin twisted around, his left arm transforming into a bladed, tentacle-like tendril that shot forward and pierced the robot through the chest, jerking it backwards toward Sin's solitary figure. 

"Get over here...!" he quoted in his usual disembodied voice, just as the robot was in his face. His left arm transformed back into it's usual form, while he completely bisected and eviscerated the robot with his sword-arm.

That's basically it. If anything, I took HEAVY inspiration from the Prototype series when writing out the powers, as Prototype 2 and 1 are my favorite games. Anyways, DrewVonAwesome, if my character is screwing with your idea then just tell me. I have multiple characters I can tweak and use here.
