The Generation VIII Pokémon that evolves into Inteleon is Drizzile. It is the middle stage of the Sobble evolutionary line, introduced in Pokémon Sword and Shield, and evolves into Inteleon at level 35.
Drizzile is a Water-type Pokémon with a reptilian, chameleon-inspired design. Its Pokédex descriptions emphasize intelligence, camouflage, water-based tactics, and a tendency to lay traps around its territory. The spy-like imagery is most strongly associated with its final evolution, Inteleon, whose long, slender design and special-agent theme draw on secret-agent fiction. Inteleon is even classified as the “Secret Agent Pokémon.”
The wording can cause confusion because Drizzile itself is the chameleon-like Pokémon that evolves into Inteleon, while Inteleon is the form most explicitly portrayed as spy-like. Drizzile evolves from Sobble, the shy lizard-like starter Pokémon, and the complete line reflects a progression from nervous hiding to stealthy tactics and then precise espionage-style combat. Inteleon also has signature traits such as finger-mounted water jets and the move Snipe Shot, reinforcing the marksman theme.
