Hariyama

Hariyama was once the TDO-version of Machamp, but now it's just... not good. It's outclassed in all that it does, though in the main series it had a signature attack on its release called "Arm Thrust". While this Fighting Type move is no longer truly a signature attack, it could be a way to buff Hariyama's performance if it's ever added.

Best PvE Offensive Moveset

• Force Palm is Hariyama’s optimal fast move, though Counter is a very close second.
• Dynamic Punch is the clearly superior Fighting-type charge move, contributing the most damage and being flexible to use.
• Superpower is a step down, and Close Combat is a further step down, and Upper Hand is actually a lower hand. 
• Bullet Punch and Heavy Slam are almost never ideal on an offensive Hariyama, even in the snow.

Best PvE Defensive Moveset

• Bullet Punch and Heavy Slam counter Hariyama’s Fairy-type weakness and hit Flying and Psychic-types with neutral damage.
• Counter is a decent alternative to Bullet Punch, but it's resisted by Hariyama's usual counters.
• Force Palm falls behind.
• Dynamic Punch is better than Superpower on defense, but neither provides any coverage against Hariyama's weaknesses. 
• Upper Hand is a tad weaker, but the fact that it's 3-bar makes it generally the best option.
• Close Combat takes too long to access, being a 1-bar move. 

Force Palm has tremendous average performance thanks to its high damage output and above average energy generation, making it the Fast Move of choice for Hariyama. Upper Hand is a low-cost Charged Move that sports high damage per energy and a chance to buff Defense. Finally, Heavy Slam is an okay move with some counter-coverage
