There's a surprising lack of unique final smashes in this game

[MarquisPhantom]

I've paid close attention to the final smashes, and on close inspection I've determined that most characters share final smash mechanics with only unique cutscenes. For example: Mii Brawler, Ike, and Greninja have the same final smash when only the way they attack being unique. I've compiled a list of the unique final smashes and I've determined that these characters have final smash mechanics not shared with others, though I can be wrong:
Luigi, Peach, Bowser Jr., Donkey Kong, Pit, King Dedede, Meta Knight, Jigglypuff, Ness, Olimar, Mr. Game and Watch, Rosalina and Luma, and Pacman.
Do note that I put all the transformations in the same category, which I know may seem a bit unfair.
Also note that I realize that Diddy Kong does have a very interesting final smash, but I have decided to list him with the transformations as well.

I don't have the effort to go look at every single final smash. Imo I don't really care since I'm not using Final Smashes. But hey, at least there's final smashes in the first place.
