No.
Evolve it from Electrike which can be founded, after obtaining the National by talking to Dawn's sister she will talk about a swarm of Pokemon one of them will be a Electrike. It will be at Valley Windworks level it up to 26 and there u go a Manectric
I think you should let it evolve because its Speed and Sp.Atk shoot up, which makes it a great Sweeper if you're interested in competitive battling online by trading to R/S/E and then migrating to D/P/P. But in game, a high level Manetric is good for taking out troublesome water Pokemon like Milotic.
Electric
