Hey Guys back here for some theory about the secret bosses,minigames etc. of KH 3!
So as for the Secret bosses id really LOVE the foretellers not only the 5 but luxu and M.O.M
Since he isn't going to appear in KH3 Story maybe he's going to appear in kh 3 secrets.
Ok now i have various theory about daybreak town,and the one that bugs me the most is the fact that daybreak town is actually shattered 
in the whole universe.And that means the Fortellers mansions are in different places for Example:
The old mansion bugs us since we saw the unicornis foreteller Ira since all the unicorns references in the mansion more than that Ira seems a really scholar person so in his mansions has a lot of books etc.
So it's possible that deep in the mansion we can find something like a "lingering will of Ira" and we can find each one of them in they respective mansions maybe even adding some dungeons when you go deeper like "cavern of rememberance" in kh2 FM.
Id really like them to be different and really difficult just like lingering will,like invi use more spells (especially water),Gula uses lightning (maybe?),aced is brute force and earth so something similiar to Laxeus etc. etc.
Other secret boss fights?well how we can miss our date with our love Sephiroth and another ff boss fight,maybe some Heartless and Nobody secret bossfight like kurt zisa and phantom.
Now,i know most of you could actually kill me if i say this but i'd really like just 1 marvel and 1 star wars secret boss fight.
Put down your plastic bad shaped keyblade ,hear me out!I don't like the idea of a world about these two franchise i agree with you in that (even if the death star would be kick ass)But as boss fight and cameos i think it can work out quite well!
Marvel boss fight:Venom
Donald and goofy:Yes
Why Venom?He could easily be a really boss fight that can use darkness,he can climb the walls so that you can use only magic (or shotlock and flowmotion) to put him down and he can be really cool to see him vanish in a some kind of black mud to reappear behind you.He can use a lot of catches and dry either your HP or MP or even both in his Desperation Move.You need to be very careful in the movement of the undergroud like some dark energy so that you can predict where he is going to attack.
As for Star Wars:obviously Darth Vader
But something special for him before the boss fight there could be a gummiship mission through the death star like in the movie
and the the actual boss fight.
Donald and goofy:No
since vader is quite slow he uses the darkness to speed up his combo movement but not his actual speed so you have to be careful when he is near you and block,he ends the combo with a force push that break your guard but he charges up a little before use it so that you can dodge that,you can use magic but obviously not forever,and you must try to attack him from behind to trigger the stunlock.
for desperation moves he can take you with force if you dont dodge his combo,if he grab you is automatically 1 hp,dry mp and focus gauge.
And least but not least the secret boss that triggers the secret ending and makes our brain die in pain.
Ooook ended the bossfight segment let's talk about collectibles and minigames
As for collectibles id like something really fun to search
first id like the return of the stickers like kh 2 fm and BBS fm
second the reports of either Luxu or M.O.M
well...the pooh pages since it looks like it's already confirmed
The toy story toys that are scattered through the worlds
and well i really dont have other ideas there.
Maybe we can find some lost books of merlin?and in one of them we can find the jungle book?Idk
As for minigames well.hope in something better in winnie the pooh
Frozen is probably going to be some kind of musical world but with some fighting in it
Now Wreck it ralph would be really cool since it's an arcade,so lets see...
Merlin or someone other find and old video game cruiser Cid tries to fix it (in the meanwhile the story goes on)
and when its ready you can enter in this big hud with various minigames,shootings,sugar rush and on and on 
then end the world with the wreck it ralph villain that i don't remember now the name.
Now its a wild fantasy of mine but id really a tournament of robot in San Fransokyo where you build your own little robot and make him fight,but idk seems cool to me.
And obviously the hercules tournament more flashy,diffcult and grindy!
Oh and the struggle tournament too!maybe more cool since it was a little dissapointment in kh 2

AAAAnd the side quest,now im sure 100% that they are going to put the heatless hunt and mission in it,they did it in 358/2 and X,Unchained,union x so im sure they're doing something about it.
But i'd like to see some request like a dude that want to talk to you and you go there,find the thing or fight the heartless or idk.
Well thats it if you have some ideas let me know!

These are pretty swell, badass ideas! I think they could work very nicely!

 

For secret bosses, I'd love:

• A Heartless. I want to face a Heartless Secret Boss again, such as the likes of Kurt Zisa and Phantom, as both were awesomely designed!
• A Nobody. I don't think we've ever had a Nobody Secret Boss, unless you count the Absent Silhouettes and Data versions of the Organization members, but that's besides the point! I want to see a giant Nobody secret boss!
• An Unversed. I think it would be badass to see an Unversed as a secret boss, and I'm sure the fight would be cool!
• Gilgamesh. He's perfect for a secret boss, and his reason for wanting to fight Sora would be perfect: to add the Keyblade to his weapon collection!
• Caius Ballad. This monster of a badass is someone I'd love to fight against! His powers of darkness and time and his giant sword are enough to deem him secret boss status!
• Villain Of The Next Saga. Kind of like how Xemnas was the secret boss of KH1. Let's make this happen again, but with a mysterious secret boss that could hint at the possible villain or villainess of the next saga!

As for side quests, one idea I love that's been floating around here is finding all the Experiments, the ones from the Lilo And Stitch series! That'd be fun, I'm sure! And well, I don't really know much else!

 

And I've drawn a blank at mini-games.

 

Also, I love your ideas for Venom and Darth Vader as secret bosses! Very creative on your part!

Thank you!Yeah the experiments is a cool idea but not everyone of them i think like 100 can be okay because all the 629 could actually be a little annoying to find for me lol.
And you can hide them in either certain type of heartless that steal them or treasure chest so it's cool
