I really wanted to see how Villager, Wii Fit Trainer, and Rosalina would have been implemented into the story. Especially those first two. I even came up with scenarios for them!
After

's town was engulfed into Subspace/something else if there's a new evil force, Villager cheerfully strolls out on an adventure like Captain Toad to "make things right again", blissfully unaware of what a big threat the Subspace Army/whatever new evil force really is. Eventually, Sheik crosses paths with him, trying to keep this innocent boy safe, but by the time they meet, he clearly doesn't need it anymore, so the two become an unlikely duo.

is a mysterious Captain Falcon-level badass who appears on the scene when least expected with her little animate Balance Board at her side being cute. Whenever someone else is in trouble, surrounded by mooks, screwed, she'll jog into battle and take 'em all out like a vegetarian Dynasty Warrior. Afterward, she'll join the character for the rest of the level, being a Level 9 CPU on your side if you're in single player. No need to thank her, it's what she does. During the climax when everyone teams up together, she'll be there as well.
When Samus and Fox reach the enemy's space base,

descends to their side, being the third party member, escaping the base with them on the Comet Observatory before it explodes. When the whole gang comes together to raid Subspace/whatever else, Lucas and Villager seem a little scared, but she easily comforts them by holding their hands and protecting them at all costs.
