Pokémon (1997)

S15E49 Unova's Survival Crisis

With Meloetta in their grasp, Giovanni of Team Rocket gains control over the formidable Therian Formes of Tornadus, Thundurus, and Landorus, thanks to the powers of the reveal glass activated by Meloetta’s presence and melody. Ash, Cilan, Iris, Cynthia, and Ridley rally together to rescue Meloetta and protect the world from Team Rocket’s nefarious plans. However, more powerful forces emerge, and soon Giovanni loses his grip, unleashing Tornadus, Thundurus, and Landorus to wreak havoc across Unova instead of conquering it for Team Rocket.
