Rex Malibu

History
Rex Malibu was born sometime around when Homo Sapiens evolved. He lived normally as a member of his tribe, until one day, during a tribal ritual, he was given a vision of his own immortality, and was struck unconscious. When he awoke, he held a bow made of dark energy, which he used to hunt the Phoenix population. He personally wiped Earth's Phoenix population out, breaking his bow and gathering all of the feathers. With these feathers, he became immortal, as whenever he would die, one of the feathers would be consumed and he would be transported back to the forest where he originally woke up with the bow.

Due to his age, he had a lot of time to train, and became one of the strongest men alive. He is also gay and stupid.

Merlin
Using his ability of immortality, after tens of thousands of years he went insane. Due to his nature as an immortal traveling the world, he eventually encountered Merlin, and the two became enemies. Whenever Merlin lacked anything else to interfere with, he would hunt Rex to decrease his stock of feathers. Merlin also used his influence of kingdoms to put kingdoms against Rex. Meanwhile, Rex attempted to use his power to take over several kingdoms and tribes, often succeeding. He clashed with Merlin thousands of times, and in his wars he encountered the Saba Family and the Goichei family.

Moon Wars
Rex Malibu worked from behind the scenes to spur much of the chaos caused during the Moon Wars, as he intended to take over the planet once the governments had been ravaged from the chaos.
