It's the exact same thing as the "mean 6" from The return of Harmony in season 2. It's not like they have different personalities. They're the exact same thing.
I'll organize my thoughts about this episode later, but I'm gonna say this: After watching this episode, I'm understanding the Kingdom Hearts fans who wanted the third game since 2006 and, after more than 10 years of waiting, they're disappointed by the result of that game.
The weird part is that I kinda expected it. It's not like I expected an amazing return, more like a "meh" return.
