He-Man is characterized by possessing superhuman strength. In the intro sequence of the 1980s cartoon series he claims to be "The Most Powerful Man in the Universe". He-man strength is derived from the magical powers within Castle Grayskull.
It is unknown if there is a limit to how long He-Man can remain He-Man before he reverts back to his original form of Adam; but in the 2002 series, He-Man is shown enduring the brunt of the Ram Stone of Zalasia, a gem whose mystic force can pierce any barrier or topple any obstruction. He survives, but reverts back to Adam in the process. Also when in combat against the Snake God, Serpos, He-Man was struck by the giant entity's tail and sent crashing into a mountain. When he fell to the ground, he was again in Adam's form. This suggests that even He-Man has a limit as to how much abuse he can endure before his superhuman strength and stamina are exhausted.
His physical prowess is not limited to strength, however, and he is also depicted as being extremely fast and acrobatic.
On the other hand, He-Man as a character is largely non-violent and usually only resorts to combat as a last resort, often preferring to outsmart his adversaries, his most violent actions typically consist of body throws. As per broadcast standards of the period, in the Filmation cartoon, He-Man was not allowed to use his sword as an offensive weapon. Nor was he allowed to directly punch or kick anyone. He was only allowed to destroy robotic enemies. The 1987 film and 2002 series show him fighting more aggressively. He-Man is also depicted as a leader, most noticeably in the movie adaptation where he is referred to as the leader of the resistance and Skeletor intended to force him into submission rather than simply killing him fearing that doing the latter would just turn He-Man into a martyr that would inspire others to fight.
He-Man's primary weapon is his sword, but he also uses other weapons, such as a laser-gun in the film, and equipment while battling his foes. His sword is apparently totally indestructible and able to deflect bolts of energy both magical and technological. Interestingly his sister Adora's sword of Protection is not as indestructible, as the stone in the hilt was destroyed, keeping her from making transformations. This could imply that the swords have a weak-point or that Adora's sword is somewhat more inferior to Adam's. In addition, the sword gives him the ability to transform him from Prince Adam into He-Man and back by utilizing the powers of Castle Grayskull. He also uses the sword to transform Cringer into Battlecat. Originally He-Man's primary weapon was an axe. The chest piece on his battle harness is made of an Eternian mineral called Corodite that helps add to his physical strength.

The senior Skywalker may be more machine than man, but he still handed Luke his ass once, and strikes fear in those who ever are unfortunate enough to be in his presence. While possessing great skill with a lightsaber, Vader has also perfected the Sith art of using objects as weapons via telekenises, and the old Force Choke power that has dispensed many a high ranking officer.
