If Sakurai were to do that, instead of Masked Dedede (an
actual power-up from the Kirby games), it would be quite disappointing.
This is my perspective on Final Smashes:
- Does damage
- Quick and straightfoward
- Actually has some inspiration from the games
- Makes the character invincible for a short period of time
Now, the "Big Gay Dance" might come back, however, it was one of the
worst final smashes in the game (at least from my perspective). So, why not include Masked Dedede, just like how Wario's final smash was Wario-Man?
Unrelated Note: I am hoping that a gigantic "nuclear" Wario-Waft is his new final smash.
