& here I'm sitting, thinking to myself: "Gee, Mozenrath from the tv series would be awesome to have in KH!" Mozenrath was the originally intended villain for Aladdin 3, wish they stuck with that plan.
The way I see it, there's Disney Plus now, the King of Thieves is right there for anyone to catch up on at anytime. It is to Disney benefit for the KH series to motivate players to watch more D+ content. KH has already had a direct-to-video world in the form of the Three Musketeers (show of hands, has anyone even heard of that one before it was revealed for DDD?), & The Caribbean had Davy Jones as an example of a sequel villain that wasn't around the 1st time we went to a world. Basically there's nothing to inherently oppose KoT from happening.
Furthermore, this shouldn't need to be pointed out but....
King of Thieves doesn't rule out a Jafar return! As long as the KH series is ever ongoing, there's always the chance of Agrabah making yet another appearance, KoT isn't the end of the line. They can do both. Heck, this is even true in the actual film continuity, an episode of the Hercules tv series had an Aladdin crossover with Hades reviving Jafar & it appeared to be set after the 3rd film:
(This ironically makes the show MORE canon to Aladdin than to its own film)
Jesus, what? Why didn't the 3rd film in a series get a remake? That a serious question?
Ok, how about this, KoT is worth putting in because it has a freaking Turtle/island/castle thing:
Does Jafar's revival come with a giant turtle/island/castle/dungeon with a bunch of puzzles & shit? No, I don't think it would. Nah, we'd be going to the Cave of Wonders for the umpteenth time.
