Slugma evolves into Magcargo.
In Pokémon LeafGreen, you can catch Magcargo, which evolves from Slugma, in the Fiery Path. To find Slugma, explore the area inside the Fiery Path, which is located between Route 112 and Route 113. Look for them in the caves, as they are commonly found in volcanic regions. Magcargo evolves from Slugma at level 38, so you can train Slugma to get Magcargo.
You can evolve slugma by simply leveling it up.
Slugma is a Fire type pokemon.
