This MU would basically be Sonic and all his friends Vs Goku and all his friends.
I think this would make the battle more fun and interesting, especially since Team Sonic is usually just Sonic, Tails, Knuckles, and maybe Amy (so Sonic would have to carry hard if we didn't include the rest of his friends).
I thought of a game idea , where Silver uses he timestones, For context Eggman messed up with the stones causing literally fractures in the timeline,Future, Past and Present mixing up together, Sonic Accidentally mentions the timestones in a joke and Silver being well...Silver decides to look for them himself,and I thought of having the idea of making the timestones have different names and meanings along with their abilities that Silver might use:
Future Stone: Grants the ability to see multiple upcoming timelines simultaneously, letting Silver scout ahead for danger or manifest hard-light projections of what will happen to use as platforms.
Present Stone: The grounding force. While the others push and pull through time, this stone keeps Silver anchored firmly in the now so he doesn't get erased from existence when messing with the timeline
Past Stone: Allows Silver to tap into historical data, summoning temporal echoes of past structures or even brief glimpses of historical events to solve environmental puzzles.
Memory Stone: Silver can now see the "psychic ghost data" of environments. He can look at a destroyed structure in the present and see a holographic replay of what it looked like in the past, revealing hidden paths, forgotten passwords, or secret mechanisms
Paradox Stone: The most unstable and dangerous gem. It bends causality, allowing Silver to break the rules of physics—like being in two places at once or creating reality-warping glitches to bypass obstacles.
Clock Stone: Gives precise control over pacing. Silver can use it to slow down fast-moving traps to a crawl or skip tedious platforming sequences entirely by fast-forwarding the environment.
Restart/Erasure Stone: Essentially a localized, mini-Genesis Wave. It can erase a failed platforming run or completely rewind a boss fight to a specific health threshold without forcing a full game-over screen.
Also the stones after getting the first stone Silver might go through mini boss fights with the gems
After he collects them all he Becomes "TimeKeeper Silver" instead of gold I thought of his eyes being cyan and his fur color to be Irisdent (I think that's what is it called)
Also the stones adopt Silver Lol-
