Eevee was first introduced to Lexi as a Pokémon caught to celebrate her birth. When she was a young child, it evolved into an Espeon due to its strong bond with Lexi. It remained in the family home, watching over Lexi whenever she was there. It remained there while Lexi was under the influence of Team Plasma and Team Galactic, only meeting it again when she returned home to begin her own journey.
The Alexis Saga
Espeon began her journey with Lexi as she herself began her journey, and stayed with her all the way through the Sevii Islands as Lexi's main Pokémon.
Espeon is a majestic, mature, focused Pokémon. She is incredibly loyal towards her owners and works hard in order to be the best she can be. Espeon has shown to be extremely loving towards Lexi, wanting to both protect her and be protected by her.
Espeon is also one of Lexi's most powerful Pokémon; and also possibly the closest to her. Lexi often mentions her when training with her other Pokémon as words of encouragement.
Espeon has precognitive powers that allow her to do things such as instantaneously sense her opponent's movements. She does this by feeling air currents with its fine fur. Psychic power builds up in the orb on her forehead as she bathes in sunshine.
