The Mystery is History (Japanese: なぞのポケモンＸ！！ Mysterious Pokémon X!!) is the 220th episode of the Pokémon anime. It was first broadcast in Japan on October 18, 2001 and in the United States on November 23, 2002.
While on their quest to locate a mysterious Pokemon, Ash, Misty, and Brock run into their old friends Richie, and his Pikachu, Sparky. They also meet a young boy and his Lanturn, who has made friends with a baby Lugia. Meanwhile, Butch and Cassidy of Team Rocket are hatching a plan to capture the baby Lugia in hopes of eventually catching its parent. Jessie and James also try to catch the adult Lugia, but are unsuccessful.
The scene left off with Ash and his friends discovering that Sparky is right next to them. They assume Ritchie is here. Ritchie comes out and finds Ash. Ash asks what Ritchie is doing here. Ritchie explains that after the Indigo League, he heard about a mysterious Pokémon here and spent extensive time researching the location. According to his sources, Ritchie thinks that this Pokémon is on an island nearby, so they take a small boat over there.
Meanwhile on the island, a kid is swimming around with a Lanturn and a shadow seems to be under the water as well. The kid seems to be aware of it. When he sees the gang coming on the boat he quickly tells the shadow to hide. They ask about the island. He informs them of his name, Oliver. Ash asks if he knows anything about the mysterious Pokémon that's supposedly around here. Oliver seems nervous, almost as if he was faking his uncertainty. With no answer, the gang goes off to comb the island. When the coast is clear, something pulls Oliver under, a child Lugia! They are being spied upon by an underwater Team Rocket lab. In it resides a Team Rocket Grunt and Dr. Namba. Dr. Namba now knowing about the Lugia, dispatches a submarine for an attempt to capture it.
With the child Lugia no longer a secret, they ask Oliver why the child Lugia is friends with him. Oliver explains that a while ago Lanturn and he were caught in a storm while swimming. The waves were too rough and sent him under the water. Later, he finds that he is back on land with the child Lugia by his side. After that, the parent Lugia had soon shown itself to him. Ash says he saw the parent before, but not the child. Then they turn to Luka, and she explains that the Silver Wing responds with the presence of the parent Lugia. The parent Lugia swims out of the water next to them, with an angered look on its face. The Silver Wing starts to glow red. Everyone starts to convince the parent that they won't do anything to the child, which eventually calms it down. The child goes back to the parent and they go off swimming for a while. Ash, knowing that Luka has diving equipment, asks to see what they're doing. Underwater, the parent Lugia is feeding the child, who then goes towards Ash and gives him a playful headbutt. Above the water, Luka catches the parent jumping above the surface along with the child.
Back at Team Rocket's lab, Jessie and James look around a bit in their new uniforms. They find their way to where Dr. Namba is seeing that Butch and Cassidy are giving their report. Dr. Namba wants something so Cassidy orders Jessie and James (disguised) to go get it. Jessie starts to go into a tantrum but James politely goes out with her. Jessie is dying to get even with them.
Back on land, Oliver is swimming with the child Lugia once again and notices another child Lugia. The original child Lugia goes after it, thinking it's another Lugia, but Ritchie figures out that it's a decoy. By the time this is discovered, it's too late. With the child following it, the decoy turns into a cage. Soon, Butch and Cassidy's sub comes out and they laugh at them, except Jessie, James, and Meowth pop out in their Magikarp submarine to try to grab the catch. Jessie and Cassidy argue for a while and eventually fight each other. Cassidy wins and uses SmokeScreen to get away with the child Lugia.

TV episode debuts
Who's That Pokémon?: Spearow (US and international), Pupitar (Japan)
- Consistently in the beginning of this episode, Ash and Ritchie incorrectly refer to Blue Point Isle as Blue Rock Isle, the literal translation of the Japanese name.
- When Ash and Ritchie are fighting Butch and Cassidy, Ritchie orders his Pupitar, Cruise, to use Take Down. However, he addresses it as Pupitar instead of using its nickname.
- Ash claims that the mysterious Pokémon had flown over them, however it had actually swum beneath them.
- When Luka appeared on the scene to save Ash and his friends from Butch and Cassidy, she addresses Cassidy by name, though the two had never met before.
- When Ash's Noctowl and Brock's Crobat came from their search for Silver, Crobat's body is blue instead of purple.
- Both Lugia (Silver and Silver's mother) cannot speak human language despite the fact that Lugia in the second movie could speak through telepathy.
- In the Latin American dub, during Team Rocket's motto, Diana Pérez, Jessie's voice actress and José Antonio Macías, James' voice actor, switch dialogs, causing Jessie to say her lines with James voice and vice versa. The reason of this is unknown, though it was probably a joke from the actors, because they seemed to attempt to imitate the voices of each other.
