^so do you want one for FR and Emerald right now or just FR for now?
In any case for FR take a Machop with Secret Power.
Evolves after it can defeat a trainer's Graveler using ONLY Secret Power. Evolve it to Machamp after it solos the Fighting Dojo master.
Name him Goro.
edit: sorry wrong wording on conditioning- defeat Graveler USING secret power.
