This Pokémon spent an unknown number of episodes as Eevee.
Gabriel's Espeon is Gabriel's very first Pokémon and is normally seen walking beside Gabriel.
Prior to the series
A year after Bradley married Corrine Walker and finding out that Gabriel's depression was getting worse, and nothing they did worked, the two were down to their last hope: getting him his first Pokémon, not even sure it would work. But to their surprise, it did.
Espeon was able to help keep Gabriel's mind off that he had depression and even helped during some of his episodes. It was thanks to that bond that Eevee evolved into an Espeon.
Personality and characteristics
Espeon is a very calm Pokémon. She rarely acts without thinking and definitely doesn't act without Gabriel's order. She cares greatly for her trainer and obeys only him. She is very close to him having been with him since he was seven and helped him deal with his depression. Espeon is the one that calm Gabriel down after an episode and she takes her job looking after Gabriel very seriously.
