That is quite the interesting development with the Cuphead Mii costume Spirit battle.
But honestly... I'm still not surprised. As
ForsakenM
said, the mindset that Sakurai and his team wouldn't add a character just because they're a Spirit is such flawed logic. As I've said many times, if Sakurai or Nintendo want to add a character, a little image isn't gonna stop them. "
But it isn't JUST an image, there is a battle too and blah blah blah..." Okay? Again, if Sakurai or someone else REALLY want to add a character who is a Spirit, I genuinely don't think they're gonna say "
Aw well shoot, looks like they're an image and have a battle, guess they're just impossible to implement..." If someone is going to make the argument that changing up the battle and how Geno's Spirit works would be "too much work," um... I hate to break it to you, but "Everyone Is Here," 100+ stages, and how much Sakurai works is an indication that Sakurai probably will find a way to give the people what thet want. Changing how a Spirit works isn't really as intensive as 100+ stages and having every Smash character return, so I don't really get the argument then...
As we've seen with so many things in Ultimate, the impossible cam become possible. "Everyone Is Here," Ridley, King K. Rool, Banjo & Kazooie, etc., so many dreams have made it into reality, no matter how you slice it. There are gonna be people who say "
But that doesn't mean Spirits will be upgraded!" Yeah... I guess? But coupled with the point that Sakurai will upgrade a character if he really wants to, the fact that so many "rules" and "never-evers" have been broken really should get people to stop making up rules.
Bottom Line: If Sakurai/Nintendo/Square Enix want to upgrade Geno, one battle and a Spirit aren't gonna stop them.
