Awesome / Pokémon: The Mastermind of Mirage Pokémon
All the flashbacks to the older Pokemon films, very nostalgic.
Mirage Mewtwo's defeat at the hands of Mirage Mew.
To recap, first Mew blocks the attack aimed at Pikachu, then after Mew is seemingly curb-stomped and deleted. It returns Big Damn Heroes style and uses it's connection with Mirage Mewtwo to hold the mindless super hologram still long enough for Pikachu to finally finish it off.
