Descent of the Fire Lord! Burn Nova Revived! - S2.E24

To make sure that Ricky was an Omni Lord, Drum searches for Ban and Ricky. When Drum finds Ricky and asks for the truth, Ricky looked like he was hiding something. When Gratos appears, he didn’t go for Ricky, he went for Ban. The moment Ban sees Gratos, he begins to act violently. Ricky decides what to do and he approaches Ban with the Omni Lord’s Crest in hand. After that, the Omni Lord’s Crest flashes, and Fourth Omni Fire Lord, Burn Nova appears there.
