Well...I still don't believe Fisto was Teela's dad in MYP. In the episode "Out of the Past" the Sorceress' husband had the skin tone of MAA and dark brown eyebrows. Fisto is pasty white, with red eyebrows and an ENORMOUS fist (which the Soldier did not have). Also, the Sorceress is very cryptic in the episode and says the following:
Sorceress: "...your daughter."
MAA: "You mean my
adopted daughter."
Sorceress ends the conversation and leaves MAA to ponder.
The whole soldier losing his memory and returning to battle (and forgetting all about the Sorceress for some reason...

) screams MAA to me. The Sorceress, still knowing who her husband is, gives Teela to MAA to protect because she knows he's a great man and can take care of Teela...and Teela is with her real father. The Sorceress doesn't reveal this info to protect everyone involved, just like why Adam can't tell Teela and his parents he's He-Man. I have a thread about it in the 200X forum somewhere, but here are the pictures I combined to show the similarities between MAA and the soldier and the EXTREME differences between Fisto and the soldier. I think the Fisto story was to throw us of the MAA trail.

What Sandman said. He was never explicitly stated to be Gar, but if you're looking for your relatives and you go to where all the Gars live...you're Gar, right? Especially when you're blue.

That's how I took it.
