Why Princess Daisy is Perfect for Luigi's Mansion 4 

With Mario Wonder being released soon, Im pretty confident Nintendo will try to bring Daisy in other games since her appearance in Wonder was positively received.

Good ideas! I would take Daisy's role slightly differently from your ideas for Daisy. From the start, she would've been a playable character throughout the game being Luigi's sidekick. She would've escaped with Luigi instead of being trapped in a frame like Peach in LM3, and been equipped with a Poltergust like Luigi from Prof E Gadd. This is to respect her tomboy character and have her bond with Luigi throughout the game instead of making her another damsel in distress like Peach, even if it's for part of the game. Perhaps this time, IMO LM4 should include possessed characters including characters to rescue. Some Sarasaland characters should be among the list of characters to save. Also, it would be nice if the game includes team battles especially the final boss battle being a team vs team battle. Would also like to see some ghost and spirit boss villains within the Mario universe such as Shadow Queen from The Thousand Year Door make a reappearance as one of King Boo's allies.

To be honest I would've had it were you play as both Luigi and Daisy also have a cutscene were Daisy gives E.Gad some shit for putting Luigi through some much hell in the first 3 games I would also have were Luigi and Daisy have their own missions on different floors of the castle

With Peach getting another solo game soon, it would be awesome to see Nintendo follow up with Daisy having a big role in a future game, and a Luigi's Mansion 4 is perfect. I could see a 4th game taking place in a building that use to be a mansion but has since been converted into a big museum with exhibits inside AND outside. Luigi and co. are invited to check out the new Mario and Luigi exhibit honoring the brother's past adventures but while this is happening, Waluigi is in a cave system near the museum that legend says was used by a famous thief to store his treasure that was never found. Waluigi accidentally releases the ghost of the thief (thinking it was his treasure) and after seeing the museum, the thief uses an artifact to haunt and lockdown the whole area and takes the other character's prisoner except for Luigi, Daisy, E. Gadd, Waluigi, and maybe Yoshi who could be the fast travel system for the game. Now the team have to stop the thief from stealing everything and save the museum along with their friends.

ngl, I love the luigi x daisy ship. Dunno why, but it just works.

I wonder if this really is going to happen

Luigi’s Mansion 4 & Daisy Seems like a good name

Wait isn’t Daisy a brunette

Princess Daisy could never work due to being sidelined for too long.
