So this is SideWinder!
Seth Voelker is the creator of the Serpent Society who possessed a cloak that allowed him to teleport himself and a companion. Later, Sidewinder displayed an offensive capability which he called his "side effects": tentacle-like constructs that he cybernetically controlled which shoots charges of electricity. He was the group's leader until Diamondback defected and the Viper's Serpent Squad infiltrated the Society, after which he retired and left leadership to the Cobra. Sidewinder turned himself in and cooperated in his own prosecution in order to secure medical treatment for his ill daughter. Having served his term and gained parole, Sidewinder has shown up in New Thunderbolts #7 having reformed when he was seen in an interview.
A second Sidewinder was killed in the service of Death Sting.

A third Sidewinder named Gregory Bryan has recently been seen as part of the group under Cobra's leadership.

The motifs of each of the Sidewinders is based on the sidewinder.

He is made from a DCU body, DCU Eclipso head, re-sculpted head almost completely, Sculpted the chest piece, collar is made from Sheet foam. Sculpted belt and added some paint!
