Pyroar @ Focus Sash:
EV: 252 Special Attack / 252 Speed / 4 HP
- Dark Pulse
- Hyper Voice
OK, this one is the worst Fire Pokémon I've ever seen. I think Magcargo is still better. Bref, Flamethrower is basically used 85 % of the time, as being a STAB. Simple as that. Hyper Voice is a STAB, but is lesser powerful than Flamethrower. Pyroar can pull off some good damage, but is otherwise outclassed. Other than that, Dark Pulse is an option, because that heck Pyroar cannot use better and finally Endeavour reduces the HP to 1 once the sash was used. That's it.
