Well it was a thread that was going with all of the tie in stuff. I had said on that thread that I'd like to see Gwildor pop up on the Eternia that we know. He'd be on the run from Skeletor as the movie universe has had a return of their Skeletor as we saw at the end of the movie. Gwildor uses the key to randomly travel to get away and ends up in an familar yet different place.
This would pick up by allowing Gwildor to bring the movie into the Classic's story. In turn due to the key, the NA universe would come into play. That He-Man could then either be a future He-Man carrying the name, or how He-Man dresses when Gwildor takes him to the future.
Anyway you look at it, I'd just use Gwildor to tie everything together. IT's quick and easy, plus it works. He's not at the top of my favorite's list or a lot of others, but I don't mind the usage of the character.
