Orie

Frank, being in foster care and with no money, didn't get a Pokémon at age 10 like most regular kids did. Instead, he nicked a busted pokeball from one of his foster homes and kept it on him. A couple of years later, during the Halloween season, Frank noticed a Gengar stalking him. The Gengar liked how Frank was pulling mean tricks on the younger kids and egging the houses, and wanted to join in. Frank was shocked at first. He tried capturing the Gengar but that busted pokéball hardly did anything. The two of them bonded, and eventually they formed a friendship. Frank drew a Gengar face on his pokeball in permanent marker and showed it to the pokemon, promising (or threatening) that Gengar would be his first Pokémon. Eventually, years later, Gengar does accept.
