Stats
Jolteon has a base stat of 525, and suits the basic electric Pokemon build. It has a low hp/physical stat rating, but excels in Special Attack and Speed, and is well off in Special Defense (110/130/95, respectively). The other three average ~63.
Moves
Jolteon learns basic electric moves, including Thunderbolt and Thunder (by both tm and level-up), as well as RAin Dance to enhance their effects. Jolteon's only weakness, ground, can be countered by Doubl-Kick, learned at level 29; although its low attack will hinder the attack's strength. Oddly, it can learn a ground move, Dig.
