Sadurang is a dragon and former student of Dormammu, awoken from hibernation by Malekith. Malekith needs Sadurang's help conquering the Nine Realms. He sics Sadurang after Tony Stark, calling him the "Golden Avenger." Sadurang reluctantly agrees, reminding Malekith that he is in possession of the Second Eye of Agamotto. If Malekith betrays him, Sadurang will use the Second Eye against him.

Sadurang shows up to Stark Unlimited HQ in human form. He quickly grows impatient with Stark's security team, so he transforms into his dragon form and attacks the building. Stark and his armored friends are able to beat the dragon into retreating, but Sadurang vows to return more prepared.
