Descendants Theory: Can Hades be Mals father?

I know it's been a while, but here I am: back with more Descendants theories. This is a popular one, I have personally come to believe. It's a theory describing how Hades can be Mals biological father.

Just the other day, we finally got a picture of Cheyenne Jackson in his costume:

It's nice to see he got an update from his original costume in Hercules, unlike most villains who almost exactly wear what they wore in their original movies.





The theory of Mals father appearing in D3 has been hanging around since Disney released a video almost exactly one year ago, in which Mal responds: "Dad?" to a mysterious blue fire.

The blue fire reappears on the D3 logo:

So the appearence of Mals father, having to do with blue fire, is a big deal in Descendants 3.

A couple of new vilains are set to appear: Lady Tremaine, Mr. Smee, Dr. Facilier and...Hades.



Blue fire is Hades's trademark but him being Mals father contradicts the books greatly: in the books it is stated Maleficent Sr. told her daughter how her father was a weak little human, and she shouldn't be like him.

But this is never stated to be the truth: it is simply said this is Maleficent Sr.'s explanation.

What if, seventeen years ago, the Mistress of all Evil and the God of the Underworld found each other on the Isle of the Lost and fell in love for a year or so. They had a child together, a daughter. But there was a prophecy by the Fates: one day Hades would battle his child and lose, for the child was more powerful than him, being a demigod as well as a fairy.
He had taken the last mortal potion of the Underworld, the one he had used to make Hercules mortal. Maleficent stopped him mid-way however, and banned him to the other side of the Isle.

Maleficent would always be disappointed in her mortal daughter. She was half-human, just not because of genes. Maybe Hades hasn't appeared in the Descendants movies so far or actively in the books because he was scared of Maleficent, but now that she's a lizard and Mal has proven herself not to be as cruel and evil as her mother, he dares taking a stand, with his son Hadie.

In Descendants 3, we see a battle scene between the VK's and Hades. Was this the battle Hades tried to avoid? We shall see...
