I'm currently raising up a Manectric (with the intention of using Mega form, obviously). I'm still debating over some aspects of it, though.
Nature: Should I go Modest or Timid? It kinda plays into the moveset a little bit...but I'm not sure which serves Manectric better; greater speed or greater power.
Moves:
-Volt Switch
-Electro Ball/Discharge/Thunderbolt (I kinda want to to Electro Ball, just because I know for a fact it'll be effective on Manectric...that hight Sp. Attack and Speed. Yet part of me wonders if Discharge or Thunderbolt would be better choices. Leaning towards Electro Ball, but I'm checking others' opinions.)
-Flamethrower/Overheat (I debate this because I'm not certain if I'd be keeping Manectric out for extended periods of time. His ability is Intimidate in Mega form, and I'd want to try and exploit that as often and best as possible. Hence Volt Switch. If Manectric is gonna switch out anyways, Overheat is a nicer option...but on the chance that he stays in, Flamethrower would be the better choice to use alongside his main Electric attack. Not sure what to do here.)
-??? (Probably gonna be Hidden Power. Manectric's movepool is pretty barren. If I do use Hidden Power, then it'd almost definitely be Ice-type, but if there are better options out there for moves, please let me know.)
