No way, let's dump the whole "father figure" concept, MAA is no old man, he's a crusty warrior, the top master of weapons in Eternia, what He-man does whit brute strenght he makes up whit his combat skill. And his arsenal of weapons of course...and definitely no mustache!
Mer-man in my own MOTUverse is the Starscream of the Evil Warriors, he's a king and he's very powerfull, but not enough to overthrow Skeletor, so he follows him and waits for his chance.
My Zodac is very similar to COTUworld's, an immortal cosmic enforcers who guards that the conflict between good and evil don't spreads beyond Eternia. He's really powerfull but as he'll never let Skeletor be king of Castle Grayskull, so he'll oppose every one else, even He-man, no more the great wars will start again...
The king and champion of Avion initially made a deal whit Skeletor to make sure his kingdom would never suffer from an evil warriors invasion, but then Skeletor attacks him to take one half of the Power Sword from the peak of Avion and he sees his mistakes. Now he's one of the closest He-man ally.
No falcon-lady in my MOTUverse, althrough I find her really sexy, this green cobra lady is the Sorceress of Grayskull, and secretly, the mother of Teela.
