Zapmolcuno debuts in Chapter 33.
Team Rocket performs various experiments to discover how to create it; one example is the fusion of Flareon, Jolteon, and Vaporeon that Red'sEevee suffered.
Knowing they would need the badges of Kanto to make and control Zapmolcuno, Team Rocket allows Red to travel and gather them for them.
Green finds out erroneous information about the Pokémon Badge Energy Amplifier, and, believing it will summon an incredibly rare Pokémon that she can make a profit on, Green steals Red's badges and puts them in the Amplifier. She is shocked when Zapmolcuno is created, and the sight of the birds makes her faint.
Red, Green, and Blue team up and defeat Zapmolcuno with attacks from their starters, causing Zapmolcuno to safely separate into Articuno, Moltres, and Zapdos.
