The Power of Grayskull adapts to whatever obstacle He-Man is facing. He could win this on his own, the help of Juggernaut and Thor simply expedite the victory.
People need to stop making He-Man threads that are based solely on strength competitions until they realize the cheesyness of He-Man's powers. I'll post it again for about the 50th time.
HE-MAN gets to be as strong as he needs to be for any given task. Repeat, 'any given task'. So NOTHING can beat him in a pure strength contest, he gets to magically call on the power of Grayskull and BAM, He's has all the strength he needs for whatever. It's silly and kiddy cartoon like, but that's the character.
This is classic He-Man from the 80's, not sure about the new He-Man and if his powers are as lame.
hulk=strength, you're wrong by the way, Hulk doesn't have unlimited strength. It only has been theorized that his strength has no upper limit because his maximum anger levels have never been reached. So no one knows.
This really shouldn't be up for debate. All He-Man and Thor need to do is wrap the rope around Juggs and have him walk in the opposite direction of their opponents. Wiht this strategy they should win every time.
