Emile captured a Level 22 male Trubbish on Route 5 in a Nest Ball, wanting to add one to his team. He immediately nicknamed it, but upon returning to the PC, he chose the second Trubbish he captured due to its Ability, Stench, being better than Sticky Hold.
Hilbert, along with the rest of Emile's catalog of Pokémon, was seen in the PC when Emile was looking for a Pokémon to teach Fly.
Hilbert has a Mild Nature, increasing his Special Attack and decreasing his Defense.
