Female
Caught in Pokémon Crystal (Virtual Console) with two badges
Caught in National Park during Bug Catching Contest at level 18
Went straight to the box, hasn't been touched since.
PKHex is saying it's unable to match an encounter from the origin game, but I caught it only 10 minutes ago in the Bug Catching Contest, and it hasn't be nicknamed or trained or touched at all. So not sure what could possibly be wrong.
