Only Hitmon Primeape is better then is Top imo ¬¬

Something tells me if Primeape's punches connect, they are stronger than Hitmonchan's. xD

If we go by lore the pokedex has Hitmonchan punching at speeds of 275-361 mph+(bullet trains are slower then his punches). At this speed his punches won't be see-able to human eye(small objects like a fist aren't trackable after 200mph+ iirc) and as shown by physics more kinetic energy something has more its gonna hurt.

game mechanic basis:
well their atk base stats are the same so they would be equal in that department but Primeape is faster(95>75)... I assume this means their travel/movement speeds and not their fighting,punching in Hitmonchan's case, speed. *shrugs* ¬¬

Hate the other one!!!!

I like Primeape bacause he helped me beat many gyms and plus he's an awesome pokemon and how he was always loyal to Ash :')

This is an amazing fighting type Pokemon in my mind.
