Golden Flame

Golden Flame was a random person who appeared during the Battle for the Frozen Throne and killed many of the Lich King's zombies, all while being very confused by what was happening.

After Blackout and Ynot were somehow exposed to exciton radiation, were transported to another reality, broke the fourth wall and ended up in Axiom Nexus, GF appeared and set fire to Blackout for some reason, and then did the same thing to Archer. He was then beaten up, and ended up in hospital.

After coming out of hospital, he threw a prison cell in a car smasher, and was never seen again.
