My opening starts with a "colourful storm" over Gotham, with lightning of different colours. Then, a warp opens up and Sonic is shot from it.
his first guess was Speed Highway but he wasn't familiar with the buildings. Then he encountered Bane who was doing a crime and had someone at hostage, Sonic saves them.
O-OK, that's all I thought of so far... But the premise is the Chaos Emeralds have arrived on DC Earth and their presence on Earth is causing a severe disruption to the
Seven Forces of the Universe, in a way, effectively nerfing various superheroes by making their powers unpredictable. Such as slowing down Flash enough to make Sonic relevant.

Lex: "I have an IQ of 192!"
Eggman: "Aww."
