Role: Main antagonist; Apollonius's former partner
He's best known for his complicated relationship with Apollonius—even after 12,000 years, he hasn't moved past what he sees as a betrayal, and he still harbors real feelings for him. This unresolved history fuels his deep hatred of humanity; he's among the Angels most hostile toward the human race.
His actual goal is to restore the tree of life using Aquarion's power, but pulling that off requires unlocking Aquarion's true potential—specifically, the "Solar Wings." To push things in that direction, he deliberately orchestrates trials and challenges for the elements, with Apollo facing the brunt of it. The idea is that surviving these ordeals will force them to grow stronger and eventually achieve what he's after.
