Well... Electrike's moves before it evolves are:
Tackle, thunder wave, leer, howl, quick attack, spark and odor sleuth.
After it evolves into Manectric it learns:
Roar, bite, thunder and charge.
The TMs and HMs it learns are:
Strength, flash, roar, toxic, hidden power, hyper beam, protect, rain dance, frustration, iron tail, thunderbolt, thunder, return, double team, shock wave, facade, secret power, rest, attract and theif.
I had a Manectric a while back, and I gave it:
Thunder (a strong electric attack for tough enemies), thunderbolt (in case thunder misses), strength (a simple normal attack for enemies that are resistant to electric attacks, e.g. grass pokemon) and bite (an attack that was different to the others and also a different type to Manectric).
You can chooses any you like, but you might want to avoid:
- odor sleuth (it doesn't really help in battle very much)
- leer and howl (same reason)
- roar (only useful against wild pokemon)
- rain dance (why does Manectric/Electrike even have this move?)
Feel free to disagree if you like! Hope this helps!
