@mr_winchester: "As durable as he needs to be"!
But even he-man is not all-powerfull, enough blunt force can actually punch him so hard he reverts back to Adam. This happened two times in the 2003 series, and once in the 80's cartoon.
Funny thing about last month's comic fight is that it mirrors the events of "from eternia with death"(One invading the others universe, superman mindcontrolled by skeletor)..
It does place continuity at odds, this crossover story arch ties in to the new masters of the universe comics(directly!). The events in the new MOTU comics take place after the "new adventures" cartoon, but He-man(and the whole of Eternia with him) has only partially recovered from the mindwipe Skeletor did(To the point that he does not recognize his sister Adora), but Hordak still remembers her being She-ra one time. It makes sense that even if "from eternia with death" from the DC or MOTU point of view, He-man does not remember his previous encounter with superman.
However, Superman does not recognize or remember He-man, and looking at style of costumes from the rest of the justice league, I'd say it's either DCAU or DC Original Animated movies superman he just turned into kebab. And, AFAIK the MOTU point of view, there is only, strict universe, there have been several he-man(he-men?), who got to use the power for a short time, channeled to the then-sorceress, but only Adam of Eternia(With his earth-born mother Marlena, who is present in the DC universe of the new comic), is the direct descendant of King Grayskull and the true, fullpowered He-man.
