Lairchic is very prideful when it comes to interacting with other Pokémon. It uses its steel-coated body and fiery breath to prove that it is better than its opponent. When alone with its Trainer, Lairchic loves to snuggle despite its heavy body.
If attacked, it strikes back by spitting balls of fire it forms in its stomach. When two Lairchic meet in the wild, they fight for territory by bashing into each other with their steel bodies.
