Pyroar

Pyroar may look formidable, but it's really not. Its attack stat is too low to compete with other Fire Types. It does have the unique feature of also being a Normal Type, but that offers absolutely no real utility outside of random Ghost Type coverage moves, and even then it also leaves it weak to Fighting Type moves. It's best to just leave this Pyroar lion around your box!

Best PvE Offensive Moveset

• Fire Fang benefits from STAB and fulfills a Fire-type role.
• Take Down also gets STAB, but Normal-type moves can't be Super Effective vs anything. 
• Overheat is the best charge move available, and synergizes well with its Fire typing. 
• Flame Charge is a poor move, but can still be somewhat viable if TMs or stronger Pokemon are lacking.
• Solar Beam is strong, but doesn't suit Pyroar.
• Dark Pulse is also useless. 

Best PvE Defensive Moveset

• Fire Fang is better for defense due to its higher base power.
• Take Down can't be Super Effective vs anything, but it can have better performance due to being off-type with Pyroar's best Charged Move option.
• Flame Charge can be used frequently as a 3-bar move, but is painfully slow and easy to dodge. 
• Dark Pulse is resisted by Fighting-type attackers, but otherwise will most likely be unresisted. 
• Overheat and Solar Beam are too slow for defense. 

Incinerate focuses on high damage output and energy generation alike, making it a great Fast Move option,

Flame Charge isn't particularly strong, but benefits from STAB and offers a guaranteed buff to ATK, even when shielded. Overheat is recommended for its incredible damage threat, though it can be risky to use due to its self-debuff. Dark Pulse lacks STAB and isn't particularly valuable for a Fire-type Pokemon, but offers Dark-type coverage which can be useful for when Fire-type attacks would be resisted.
