Find your tribe in a Sea of Creativity
I came up with a Sonic prompt many of you will find interesting (or not but I'm going to post it here anyway).
Ever since they met in the jungle, Sonic and Infinite have some sort of unsolved tension between them, so they treat their battles as some sort of a twisted game amongst themselves even though they are mortal enemies. Months later, Eggman comes up with a plan to destroy Sonic once and for all but Infinite isn't having it, not when he's secretly struggling with his emotions. Infinite has a plan to fight back but for now he waits for his time to strike.
AKA Infinite betrays Eggman without him knowing because he's in love with this blue hedgehog that he's never seen before and finds him fascinating. But first he has to break free from the Ruby's control before he can do anything.
Maybe after the war, Infinite will finally have his long romantic walk on the beach.
