Hey all, I've decided to let you guys know which challenges I'll be using ahead of time. I appreciate all of the suggestions I've been given. Really unfortunate all of them aren't able to get in but I'm using this as a way to learn for next season in case I want to do this again. Also trying to limit the accepted ones to one per person to give more people an opportunity to see their challenges. As for Noah, him being left out was intentional.
G09F17R02: Yeah, considering how they're not supposed to know each other's identities that's going to be a whole other problem lol. Not to mention that Marinette signed the contract to make sure the show wasn't seen in her world and someone she knows still appears anyway. A certain stone might be able to fix things after the show though.
The following challenges will be used(Order hasn't been decided yet):
G09F17R02's face your fears challenge suggestion. Granted, I don't think every character here has a big fear that I know of, but there are definitely things they don't like doing. If they get called I'll probably do something like that. Also note that this challenge may come back again in some form in either this season and probably the next(next season is more likely than this one but I'm not ruling it out completely).
Some dude's challenge suggestion 'cause why not more Katie and Sadie screentime. (As an aside, I have watched the other seasons if you're wondering so I know what happened to Zeke. Would have taken the Zeke suggestion but considering this takes place after Action it wouldn't make too much sense. Though the challenge next season featuring him and Dakota might be close to what you were going to suggest anyway. Ella will probably be a judge in a challenge. More than likely an extra one added in the singing one in the challenge G-Man 2.0 suggested just to give more TD Characters that probably won't compete screen time)
G-Man 2.0's Hunting Challenge
Honorable mentions are omega5342, supertrip, zaksaruzilla's cryptid challenge, and Jack's challenge request on AO3.
Omega5342: Not a guarantee, but yours sounds like more a world tour themed challenge and will be considered for Across the Multiverse
Supetrip: I think I might be doing a challenge pretty similar to this one later on as a merger challenge
Zasaruzilla: The cryptid hunting challenge might still appear this season but later on. I almost considered the Bakugan hunting challenge too.
Jack: It might not be a complete one-to-one thing, but I already planned something a little similar to this as the final aftermath challenge during the merger
