Is There a Pokémon That Lives Inside a TV? (Lore Check)

No Pokémon species canonically "lives inside a TV." The concept appears in creepypastas (e.g., Lost Silver, Pokemon 731) and fan theories, not official games, anime, or Pokédex entries.

Closest Canonical Connections

• Rotom (Gen 4+) – Possesses electronics (TV, oven, fridge, fan, lawnmower, phone, drone). Dex: "Its body is composed of plasma. It infiltrates electronic devices." This is the closest match. In-game, Rotom forms change by interacting with specific appliances (Rotom Dex, Rotom Phone, Rotom Bike).
• Porygon Line – Digital Pokémon ("Virtual Pokémon"). Can convert to data, travel networks. Anime: Electric Soldier Porygon (banned episode) – inside computer/TV transmission.
• Ghost Types (Gastly, Haunter, Gengar, Misdreavus, Shuppet, etc.) – Phase through walls/screens. Could appear on a TV, but don't reside there.
• Electric Types (Pikachu, Rotom, Magnezone, etc.) – Manipulate electricity. Could power or disrupt a TV.
• Mr. Mime / Mime Jr. – Barrier/illusion powers – could mimic TV images.

Pop Culture References

• Pokémon Anime: Team Rocket's "TV takeover" gags; Pikachu's Rescue Adventure (TV screen transition)
• Pokémon Channel (GameCube) – Watch TV with Pikachu. Not inside.
• Creepypasta "Pokémon 731" / "TV Static" – Fan fiction. Not canon.

Answer: Rotom is the only Pokémon officially described as inhabiting electronic devices (including TVs in its various forms). No species is exclusive to TVs.
