From: Michaeloll | #008Did you not ever use an Espeon before? Her signature move is swift. Via level up.
Also see Pokemon Colleseum
In Gen I, nine Pokémon could learn Swift by level-up (Mewtwo from the start) and it was a TM move. Espeon's face is sort of star-shaped, but that's about it - as CM_Ponch says, a sun would be more likely to represent Espeon.
Your reference to Colosseum is lost on me - other than Espeon being one of the starters, I don't see what Swift has got to do with anything.
Also lol at Espeon being "her". It has an 87.5% chance of being male.
