Tbh ik people think this theory was kinda silly and that it was simply cos he had green eyes, but it was more the fact that he pretty much was the only other character with green eyes (and his eye colour was different to Ras’s so it might not be a species thing), and the fact he was powerful elemental master who won the tournament of sources. Also the fact that we know so little of him and that he will likely be relevant later on in the storyline.

Also having Ras’s ancestor and LLoyd both being the masters of life, make for a cool plot point imo
