Special episode, a sequel to the events in Pokémon: The First Movie (while it was aired as a side-story episode in Japan, it was given a direct-to-video release in America)Giovanni, the leader of Team Rocket, has caught a clue to the location of the powerful Pokémon Mewtwo and has sent an agent to find him. In the meantime, Ash & co. are passing through the Johto region when they encounter a woman who told them about the vitalizing water of Purity Canyon...coincidentally, Mewtwo's new location. Soon, an all-out battle between Mewtwo's clone Pokémon "family" and the forces of Team Rocket breaks out, with Ash and his friends caught in the middle.
This special provides examples of:
A Glass in the Hand: Giovanni does it twice, first with a glass he's drinking from, and to a walkie-talkie (!) near the end of the movie.
A Glass of Chianti: Or what looks like whiskey, in this case. Surprisingly untouched by 4Kids for the dub.
Epic Fail: Domino fights her way past a trio of Scyther and then flawlessly flips over them... only to slip on a wet floor and get her head stuck inside a pail. Doubles as Irony, since she had previously forced Jessie and James to mop said floor.
Evil All Along/Bitch in Sheep's Clothing: Domino initially appears to be a cute and sweet college girl and Cullen's assistant, but when Jessie and James make the scene, she reveals herself to be an elite Team Rocket agent working directly under Giovanni himself.
Eviler than Thou: Domino proves to be as such to Jessie, James, and Meowth, popping their balloon while expressing disgust at their bumbling ways and declaring them a disgrace to Team Rocket.
I Will Punish Your Friends For Your Failure: Giovanni is no fool. He knows testing the limits of Mewtwo's power is futile, so he despicably threatens to murder his clone brethren, and all the nearby Pokemon, if he does not cooperate and serve him.
Kick the Dog: Giovanni actually snaps at his precious Persian to be quiet.
Pet the Dog AND Kick the Dog in a row: Domino thinks the baby clone Pokémon are cute and even holds and pets one...then she has no qualms knocking out their parents with electric tulips.
Laser-Guided Amnesia: Mewtwo does this to all of Team Rocket (as well as Luna and Cullen) except for Jessie, James, and Meowth in the end, though one can't help but wonder why he didn't think to do this beforehand. Subverted with Ash and co., as Mewtwo allows them to keep their memories, and seeing as Ash says "This time we'll both remember," Mewtwo may have at least told Ash and Co. about their memories he wiped in the first film.
Love Redeems: Sort of. He was actually one of the good guys, but Cullen Calix was obsessed with studying the spring of Purity Canyon, even if it meant harming it. But once Mewtwo wipes his memory, he realizes that he's in love with Luna and that this is more important than research, so he settles down with her rather than pursue his ambitions.
Offscreen Moment of Awesome: A massive battle undoubtedly takes place while Ash is taking Mewtwo to the spring between Brock and Misty vs what looks like every Team Rocket operative. It's going to start up and...we cut to Ash dragging an injured Mewtwo up the stairs. We NEVER see any of the battle.
Parental Substitute: Mewtwo acts much like an anxious father regarding the other clones, and debates whether he should let them set out on their own or if he should make them stay where he can guard them.
Does it count if Mewtwo technically is one of their parents?
Yes, since he isn't biologically related to them. He's their creator, but not their father.
What the Hell, Hero?: A subtle one; Ash needs to save Mewtwo's life by throwing him into the spring. Cullen then tells him not to, because it might contaminate the spring, which he's obsessed with studying. Ash's response is to look pissed at Cullen's selfishness and throw Mewtwo in anyway.
You Are a Credit to Your Race: Mewtwo wants to know the reason why Ash is trying to save him. Ash replies you don't need a reason to help another. Mewtwo then considers Ash unique, one-of-a-kind. Ash informs the genetic Pokemon, everyone is unique, and that includes him too.
Zerg Rush: By various Bug-type Pokémon after Team Rocket occupies Mewtwo's island home. By the way, Bug is super-effective on Psychic. Until the Psychic gets its turn.
