Zygor Snake-Arms

Zygor Snake-Arms was an older Warhammer character, from when Greenskins were not as resistant to Chaos. Having once been a normal Night Goblin, Zygor's tribe was annihilated by wandering Chaos warriors. However, they were so impressed with his fighting that they took him in as one of their own, and whilst fighting for Chaos, was "gifted" with multiple mutations, remaking him into something more akin to a Daemon than a Greenskin. His legs elongated, his head fused into his torso, and his arms turned into two reptilian, snake-tail esque tentacles, along with growing a tail identical to said arms.
