You know, a lot of people joked about Piranha Plant and "Waluigi tears", but really most Waluigi fans were super happy about the plant. Even before the mysterious absence of Spirit promotions from the first Fighters' Pass we all thought ATs deconfirmed, so it actually felt really good to see any sort of weird lanky Mario character. That being said, given recent rumours; a certain trademark registration; and of course Min Min, it's say it's more "when" than "if" at this point - even if not for Ultimate.
