Set Description
Thunderbolt is Jolteon's primary STAB move, 2HKOing Electric-weak foes, such as Starmie, Vaporeon, Dodrio, Aerodactyl, and Cloyster with a 20.8% chance to 2HKO Kangaskhan as well. It also 3HKOes Tauros and Jynx, 3HKOes Clefable 69.4% of the time, and 4HKOes many bulkier foes, such as Snorlax, Gengar, Alakazam, and Zapdos. Thunder Wave allows it to spread paralysis across the opposing team, with its high base Speed allowing it to get the jump on any unboosted foe. Super Fang is Jolteon's best option against many full HP foes, such as Exeggutor, Zapdos, and Snorlax, and it makes Jolteon's best switch-ins—such as Golem and Exeggutor—think twice about switching in. However, unlike Thunderbolt, it can miss and cannot score critical hits, making it unreliable at times. Explosion is a powerful tool, OHKOing Jynx and Alakazam 66.7% of the time and doing 72.9% minimum to Chansey. It also does serviceable damage to physically bulkier foes, doing 52.6% minimum to Exeggutor and 54.9% minimum to Tauros. Explosion is also useful for finishing off foes weakened by moves such as Super Fang and Thunderbolt, or it can put a foe into revenge kill range. With Jolteon being the fastest viable Pokemon, it has a lot of leeway in its ability to weaken or paralyze a foe before using Explosion.
Jolteon can be used as a lead, a mid-game progress maker, or a late-game cleaner. Its most notable position is in the lead slot, as it can take advantage of its high base Speed, Thunder Wave, and Explosion to be able to threaten all relevant leads, paralyzing lead Gengar and cutting the accuracy of its Hypnosis down to a mere 45% while also threatening other common leads, such as Jynx and Alakazam, with paralysis and Explosion. As a mid-game progress maker, Jolteon uses Thunder Wave and good coverage to revenge kill and force trades with important threats such as Gengar, Clefable, Kangaskhan, and Tauros. Jolteon as a cleaner uses its high base Speed and powerful STAB to pick off weakened foes at the end of a game, beating out other common late-game cleaners such as Starmie. In this case, Jolteon should be kept hidden until the end of the game, as it is much more effective at cleaning if the opponent is caught off guard. It should also be kept hidden until Exeggutor and Ground-types have been eliminated, as these foes pose massive issues for it. All of these Jolteon sets work extremely well when paired with other Explosion users, such as Kangaskhan and Exeggutor, as they can either carry on momentum that Jolteon generates early- and mid-game, or they can remove barriers to Jolteon cleaning, such as Kangaskhan, Exeggutor, and Tauros. Lead Jolteon and mid-game progress maker Jolteon's main utility lies in outspeeding and paralyzing at least one foe, and then threatening foes with strong attacks and Explosion.
