The second OP sequence was played during season 2. There are two slightly different versions of the sequence; the first version plays the same scene of Aster summoning "Archlord Zerato" and features Dr. Crowler smiling at the end; the second replaces the summoning scene with a clip of the current episode's Duel, and Dr. Crowler's expression becomes a defeated one. This was followed by Teardrop.
