Unused Bosses that Never got into Sonic Mania 

I feel like that originally this game was going to be more like Sonic 3 in terms of how much content it had in fact there’s even evidence to suggest that Hyper forms would have returned

The Lava Reef boss actually looks pretty interesting, maybe we could get something like it if we get a sequel to Mania or something.

I've always wondered what stuff was deleted from Sonic Mania, other than the Art Book the physical copy of Sonic Mania Plus I never saw much about deleted stuff, The beta Egg Reviere was insane too

The old phase 3 for the Metal Sonic boss fight was removed as well

Egg reverie boss looks like a bit of a mess, but that is probably because it was unfinished. :P

i love the concept of having to fight the hard boiled heavies in egg reverie, and possibly when eggmans turn there will be eggman robots like maybe a buffed DD wrecker and metal sonic for sure

All bosses are very interesting. If they were inserted and included in the game, it would be more exciting, intense and impressive!

I see what the final boss battle alt still unused. Context: In Eggman Final Boss Sprite there's an unused sprites Nobody knows what this giant robot does. :/

The beta Drillerdroid fight is pretty interesting, I wish that it got used.

If i remove the other 2 Boss files, The last one will play normally? (Im only interested in eggjanken I like it's design ^-^)

When sonic and Eggman got rock Eggjacken: really?

Why would they unuse these masterpieces🥺

this final fight should have stayed, it's kindaaa epic

I imagine in the originally planned All-Out War version of Egg Reverie Zone, the ninja Egg Robo and the motobug racer Egg Robo would take turns going NYOOOOM back and forth across the screen.

Eggjaken was so cool!

If sonic 3 boss got a revamp (upgrade)

Is there any way that we can try these out? I would want to try these bosses?

4:32 the sky is blood red

the phantom shinobi just jumpin

4:32 the original boss battle starts

that Studiopolis Boss I think the name would be the Economic Crusher

I don’t get why the time changes randomly in the super sonic zone is it because it is an unknown area. Is the reason why you lose when super sonic is because it has no O2 so if you are not super sonic that why you lose

Thats really cool

Unused bosses in Sonic Mania has completely out. 😠

How did you access these bosses

Boss 2 is in the game but you don’t go underground

Egg janken has the wrong boss music for act 2

The egg revive sorry wrong spelling the egg revive was my favourite

‏‪4:04‬‏ i can see why they delete that boss 🗿💃

Clearly the last one was scrapped early

I like the original Studio apples Boss😊

So all the hardboil heavies were supposed to get a final form

The egg janken is sentient, change my mind.

Smitty Werben Eggman Janken.

Oh yeah I see unused

The driller droids in the game
