I feel like I see more people telling others to chill on Smash news than I see Thirst Masters......but yeah. Just enjoy the time off or hanging out with your family. Holiday vibes and all that jazz.
They could just make GBA Zero a costume yeah. If they wanted a Simon/Richter deal, Geo and .EXE could borrow moves from each other. MMX and Zero could too, but their differences are more drastic I feel. Like, you could even put Mega Man X and Axl in a fighting game(not just Smash) and in theory, make them have a Ryu/Ken dynamic, but that would mostly be limiting on Mega Man X's part, since he'd mostly stick to MMX7 weapons, where he and Axl share the same boss weapons.
Final Smash characters being playable at least happened once. And while it's pretty unlikely to happen again, I'm still gonna show some support for Mega Man X and the rest of the Gang Members. But if we did see someone get the AT upgrade, it'll probably be Waluigi because of how popular he is in the context of Smash. Outside of Smash, Knuckles and Zero I'm pretty sure are Waaaaaaaaay more popular. Heck, even Guile might be too.
EDIT: If you want to talk more Mega Man Stuff, I already made a thread, though I don't know if you saw it already.
