Also, I forgot to mention it before, but today I woke up from dreaming about playing Ultimate at this weird old married couple's house in another country (I'm gonna say Spain?). So they wanted me to help them unlock things, since they didn't really know what they were doing but wanted more characters, so I turned on WoL to see if I could do anything there.. Except it wasn't WoL. The opening cutscene came on, and instead of the 'lord of light', Galeem was described as 'an evil moon' and it mentioned that he'd tried to destroy the world once before. All of the fighters gathered to face him, but this time it was set in a battle-torn city square at night (think Westopolis from Shadow The Hedgehog).
Galeem started turning people into spirits, but it was like there was a pop and they were immediately the floating spheres with the images on them. This one cowboy-ish character tried to escape, but Galeem turned his horse into a spirit, and then turned him before he even hit the ground. It then cut to Sonic watching, and he smirked and tried to pull out the Ray Gun item, but his holster was empty. He said something like "Heh, I guess even guns have spirits, huh?" And then Galeem got him. But instead of becoming a spirit, he and the other playable characters became like statues made of bolted plates of metal. I specifically remember telling the couple something like, "Huh, this is weird. In my game it starts with them on a cliff and they get vaporized."
The game started, and instead of Kirby, the only survivors were Mario, Inkling, and Link. Rather than the world map, though, it was like a beat em up where you can swap between the three (like the Nicktoons Unite series). They left the city and went into a crystal cave that was being mined, and I thought I saw Shadow off in the distance and thought "Wait, but wasn't he just an assist?" And then I woke up. I wonder if I would've found Geno before long, if the dream had kept going? It wouldn't be surprising at all.
