In WCI, Katakuri was originally introduced as a logia, but then retconned into a "special paramecia".
One thing I find interesting about the concept of "special paramecias" is that it just seems to arbitrary. Why does Katakuri have logia intangibility when other paramecia like Doffy, Mr. 3, or Cracker don't?
What I think is very likely is that "special paramecias" are just normal paramecias who used awakening on their body.
Some paramecias with the ability to produce and control certain elements(string, biscuits, mochi, etc.) have awakenings that allows them to transform objects into their element. For example, Doffy can turn objects into strings, and Katakuri can turn objects into Mochi.
I believe that Katakuri's logia powers are simply a result of Katakuri using his awakening on himself, turning his body into mochi. I believe this might be an advanced awakening technique, as we didn't see Doflamingo use it. However I think it is very possible that Doffy could use it if he makes a comeback in the future.
I think Magellan might have this ability, albeit given how lethal his awakening(poison that spreads) is, he likely seldom uses it. If Teach has awakened his gura gura no mi, perhaps he can use it to turn himself into vibrations, giving him super speed.
I can see Kid and Law using a similar technique of applying awakening to their bodies, although obviously in their case, this won't give them logia powers. Still, I think it would be a possible next power up for these characters(assuming they don't die lmao). By applying a light magnetic charge to his body via assign, Kid will gain the ability to fully manipulate his body using his basic magnetic powers. This will allow him to levitate and move in 3 dimensions. He could also use assign to apply a heavy repulsive force on his body, making it difficult for anyone to attack him with a sword(or other metal weapons).
Law could coat himself with Kroom to become intangible, or RRoom to levitate himself with tact.
One final possibility I want to talk about is Fujitora. I think he could use awakening to manipulate the gravity around his body in order to move at immense speeds,.
Anyways that's the theory. Special paramecias are just normal paramecias with an advanced awakening technique of applying awakening to their own bodies. We will see more characters do this in the future, including: Doffy, Magellan, Kid, Law, and Fujitora.
