Zeron Brotherhood

The Zeron Brotherhood are major antagonists in the Tales of Arcadia trilogy, serving as the secondary antagonists in Part 1 of 3Below, with the Zeron Alpha being a minor antagonist in Part 2.

They are a trio of bounty hunters sent by General Morando to kill Aja and Krel Tarron and crush the cores of King Fialkov and Queen Coranda. It is also revealed that he had them kill Varvatos Vex's family to make him vulnerable enough to lower the shields of Akiridion-5 so he could return.

Zeron Alpha is voiced by Darin Pe Paul, while Zeron Omega was voiced by Ann Dowd. Zeron Beta doesn't have a voice actor.

Background
At one point, the Zeron Brotherhood attempted to steal Gaylen's Core from the guard of House Tarron for unknown purposes. However, the King and Queen managed to stop them and give the core to the Trollhunter named Kanjigar the Courageous, hundreds of years ago, who kept it safe in a cavern he made, called "the Deep", where anyone who enters it faces their greatest fear.

It's also revealed that after General Morando was exiled from Akiridion-5 for high treason, he hired the Zeron Brotherhood to cause a massive bombing, thus killing Varvatos Vex's family and hundreds more Akiridions. Despite Varvatos begging King Fialkov to interfere with it, the latter refused as he was more interested in increasing the defenses of the planet. Following this, Morando ordered Varvatos to lower the shields while promising no one would be hurt upon his return, which he did upon being blinded by his anger.
