Prologue
- Have Sonic's world be encroached on again by an improved plan from Nega from what he was doing in Rush 1. As he is perfecting the travel between worlds.
- Nega is able to do this and is more powerful than ever by researching into Sonic's world and finding the Sol-Dimension's equivalent of the (Master Emerald / or their version of the black arms whom could be peaceful in Blaze's dimension before being manipulated or mind-controlled by Nega).
Story Highlight Cliffnotes. Part 1 - Finale
- Sonic and his friends in Part 1 are dealing with the invasion of their world and coming up with theories on what is happening, (Aliens, Eggman, etc...) working with GUN, team Dark, and building a party for the adventure.
- With some of Sonic's friends (Cream / gmeral) be plucked from their dimension due to shenanigans from Nega, (whom Eggman is not working with this time).
Part 2:
- Cut to Blaze's dimension's team, (Blaze, Marine, Johnny, [Cream, Gmeral, both fell into a portal]) with her supporting cast doing the same finding out the true culprit.
Part 3:
- Sonic's team is sent away willingly to Sol-Dim by Eggman (who was going to do the same as Nega but did not have the time to do so since he deals with more heroes and their problems.)
Part 4:
- Both parties meet up join forces and you explore the Sol dimension more.
Part 5:
- Your choices, throughout the game are realized and the final assault in Nega's fortress.
Finale:
- Final fight: 2 or 3 Super form fight (Shadow's Super form joining is character choice/story dependent). With maybe a cool Super Form Swap, (Burning Sonic / Super Blaze).
Story Endings (Best is canon):
Normal:
- After defeating Nega, Sonic was able to get his friends out to their dimension first before himself. But due to your fight lasting too long with Nega the Dimensional fabric is so damaged it closes before Sonic could leave, stranding him in the Sol-Dimension. (With only the possibility of reality healing enough for them to attempt to get Sonic back over).
Best
- Nega is defeated and sent away, (Could be to Sonic's future to explain Rivals games. Although I hate Silver stealing another one of Blaze's unique cast members). Reality is back to normal and the suprise at the end is that Blaze now attempting to understand how Sol-energy was used by Nega is now able to travel between dimensions freely. And with the Sonic crew seeing the world taken over by Eggman starting "Sonic Forces".
Character story-line endings:
Amy:
- Same as Chronicles' decisions. With the Canon being Soni,c telling her off. To explain her extreme character shift in Forces onwards.
Tails:
- Either allow him to do things on his own and fail on his own.
- Or constantly build dependence on Sonic. (This being canon to explain Forces).
Shadow:
- Establish a friendly rivalry/competition with him throughout the game to explain his (Vegeta-isms in "Forces".
- Choosing to do so will allow him to join in the Finale as Super Shadow to make getting Best Ending easier)
- Or don't and remain distant.
Blaze:
- Similar to Amy, (Romance [as a continuation of hints throughout Rush 1 & 2 and Black Knight, etc...) or Best Buddy route.
- Neither is ever confirmed as Canon,
- So Sega can allow people to play with their toys/ships.
- But the Romance ending can be hinted at through art/Tails Tube/ Sonic Channel art/dialogue/etc... to drive fanbase engagement as they already do (most recent example being Crossworlds dialogue between the two).
- I have other endings for Knuckles/Cream/Rouge/Omega/ etc... But I want you guys to think of some.
Some ideas are also: Super Blaze design could be reminiscent of Proto Blaze like this
