Haechi

Haechi (voiced by Todd Haberkorn) is a Marvel Comics character that appears in Avengers Assemble.

He is a teenager who was affected by Terragenesis, turning him into an Inhuman with the power to absorb energy and converting it into fire blasts, and transform into a monstrous dragon/bull hybrid. He was caught in the crossfire of the Inhuman Registration Act, and was later mind-controlled by Ultron, but he was freed from Strucker's control by the Avengers.
