Luca & Karab at each others throats. Karab Amabo was the first mediator created by the god Zango. He was made perfect for his job, until he began questioning his purpose. Karab eventually rebelled against his gods, and nearly destroyed Kotia. He was then defeated and sealed away. Because he was made nearly god-like, he could not be destroyed. But the gods still needed someone to intervene for them. Thus, Luca was created by Ixx, but he was given limitation through his flesh. (Karab was completely spirit like the gods.) Later, Karab escaped from his magical prison with a seething hatred for the gods, and discovered that he had been replaced. From then on his ultimate goal was to destroy Luca and get his revenge on the gods.
"Normally Luca doesn't posses wings. It just seemed poetic to put them on. Cause Karab was made by Zango (a dragon), and Luca, by Ixx (who has angelic wings)."
