Linkera was a man created by the Terra Warriors to battle their enemy, Chaos. He has the brute force of a demon, and the focus of an angel, but his body was all human.
After avoiding his purpose in life for a while, he fulfilled his destiny by fighting his adversary. He was unable to destroy him, but he did incur memory loss on Chaos.
This brought him time and he used it to find a way to destroy his nemesis.
He used this time to create the Linkatsa Religion, the Linkatsu Arts, and founded the Linians.
