Ermac has strong telekenesis, he consists of loads and loads of souls with enough power to use telekenesis on almost anyone, and in that range is machamp.
In games he can use his telekenetic moves against people taller and heavier than machamp, and is almost no limit to his telekenesis, allowing him to use it over and over again if he wishes, if he couldnt do this they wouldnt allow him to in the game.
Besides Ermac also has a great axe he wields with one hand with ease, one slice and Machamp would be in agony, and would greatly decrease his chance of winning.
Back on topic Goro and Kintaro are much bigger than Machamp in height (from the pokemon show size and their size), therefore longer reach, and their punches would hurt Machamp aswell, and Goro can have a blade on each arm which,if sliced, woul hurt Machamp alot because a knife slash hurts almost any skin. Or does he have blade proof skin now?
Yeah but he can lift physically strong quite easily, people with very very strong minds or mental powered people and things like them have telekenesis, not brutes like Machamp.
Its far off but they might do it, Kintaro and Sheeva hold Machamp/distract him while Goro stabs him over and over again in the head or back.
They can't hold him, he's too physically strong. And he has attacks like Earthquake, etc.. to keep them off kilter while he pops heads. Giga Punch would end any of them. And other pokemon have Tk, it's not like Machamp has never gone up against it before. Besides, Ermacs TK has stipulations, he can't fatality Machamp until he wins the fight, which won't happen.
Continous ground smash until Machamp is weakened then, hit with the axe at a critical point/ or keep using that green blast he has (projectile, forgot what its called) until he either dies or goes into fatality mode. Even if Machamp gets up close Ermac can stop some punches with his power, only if for a few seconds so he can move away, or use his telekenetic move that sends them from one side to the other face first.
Also about Goro and co. They way this Machamp is portrayed he has a better chance of winning, but MK team has spme long range moves aswell, where Goro brings up fire orblades i forgot from the ground in MK Deception and it damages the enemy and its an attack that able to be done for ages, havnt really been Kintaro or Sheeva dont really like them, well I dont like Goro either lol but hes gd.
the tk machamp goes up against is psychic types and they end machamp. dont forget about machop. he isnt gonna sit by and little the shokan beat up his brother (or father which ever you choose)
