Jolteon is one of my favorite Eeveelutions and electric types! Jolteon is one of the fastest Pokemon, is one of the classics and is another one of those Pokemon so it should have deserve a great fast speical moveset. To bad that Jolteon can't learn elctro ball with all this speed or else I would of made another set.
Jolteon @ Focus Sash
Ability: Volt Absorb
Role: Fast Sweeper
Nature: Timid
EVs: 252 SAtk, 252 Spd and 4 HP
Moveset:
-Thunder Bolt
-Hidden Power (Ice)
-Wish/Agility
-Baton Pass/ Volt Switch
Thunder Bolt is the most reliable electric type move to hit most Pokemon more than Thunder plus it gains STAB so yea, you will have to look hard enough to find the perfect Eevee with the correct hidden power other than that it covers its ground type weakness and will kill grass types which are resistant to electric type moves and if you have ice you could kill a flygon or a garchomp or any dragon type (most dragon types have earth quake) then you got a great jolteon, Be paitent with wish cause if you use it on the first turn and jolteon gets hit and is left with 1 HP then you can attack the opponent and heal up, Baton pass is to baton pass wish to another opponent if you have to or if you want volt switch you can get your jolteon out of the battle quickly and it will also do STAB damage and you can pass on wish to one of your good allys or if you go with Agility you can baton pass speed to one of your slow allys so you don't have to have Trick room but can't volt switch agility to your ally's though. and heres a little tip about Jolteon's Volt Absorb ability, if you are faceing a opponent who may and might use thunder bolt or thunder wave or any other electric type move then quickly switch to jolteon and it will gain health and immunity and with a Timid nature you can out speed lots and lots of Pokemon more than usual. I think I'm one of those people who put lots of details in this set....
