I am still trying to beat Platinum and had a Thunderstone so I evolved my lv 26 Eevee into a Jolteon.
Right now this is what I have
Modest nature (didn't even realize this until after I evolved him haha)
Sp. Atk 83
Sp. Def 70
Ability - Volt Absorb
(have not raised many levels and only recently started playing around with him)
Right now he is being awesome with Thunderbolt and even killing things almost ten levels higher than him, but I'm looking at this for the future:
Last Resort (more like a placeholder at this point)
I just want him to be a straight attacker, wondering if this is what I should aim for? I am not planning on EV training because ughhhh F that, and am not really going for truly competitive but was interested in just how far I can take him haha xD
That set should be fine in game, I suggest you use Charge Beam over Last Resort, as Jolteon's attack is piss weak and Charge beam has some use getting SpA boosts on Pokemon you are finishing off.
Other options you might want to consider are Thunder Wave and Substitute.
But yeah, Jolteon's in game options are limited as it has a small special movepool and getting the ivs for a functional hidden power sucks.
Cool, I might play around with him some more, maybe transfer him up to Black or even X if I get it eventually.
