Jolteon

Jolteon is a powerful pick in STABmons thanks to its lightning fast base 130 Speed, which lets it get the jump on all relevant threats and gifts it a sky high 25.39% critical hit rate. This is complimented by it gaining powerful new coverage moves in Super Fang and Explosion to make it the fastest relevant Explosion user. It also has access to a powerful STAB Thunderbolt, which 2HKOes the omnipresent Starmie and 3HKOes many other foes, such as Tauros and Kangaskhan. Its ability to spread paralysis with Thunder Wave is nearly unmatched thanks to its Speed. Jolteon also benefits immensely from the decreased relevance of Ground-types in STABmons, as they threaten to wall it.

However. Jolteon is held back by its poor physical bulk, being 2HKOed by most common physical attacks, as well as its Explosion being relatively weak, dealing just over 50% to bulkier foes such as Tauros, Clefable, and Kangaskhan. Jolteon tends to get outpaced in damage, as it can only 3HKO most foes with Thunderbolt. The prevalence of paralysis also doesn't do it any favors, as once it becomes paralyzed, it becomes far less threatening and loses its most valuable trait.
