Welcome to my 7 part Modern and Boom Crossover! This story takes place 1 year after Sonic Forces. In the Modern universe, a huge incident caused Modern Sonic, Tails, Knuckles, Shadow, and even Dr. Eggman to get transported to the universe of Sonic Boom. The bad news is, they don't have any Chaos Emeralds to head back home.

Modern Eggman told the Modern heroes that they will not fight, until they get back home. Modern Eggman even said that he will not pull any tricks on the heroes and reluctantly, the heroes and Eggman came to an agreement for a temporary ceasefire.

Later, the Modern team would meet some of their Boom counterparts. The Modern team told that they need to get back home. The good news is, Boom Eggman has a interdimensional portal machine to send the Modern team back to their dimension. But the bad news is, one fight in Boom Eggman's lair caused his (Boom Eggman) interdimensional portal to be damaged severely and it'll take about a week to be fixed.

The Modern and Boom characters will have exciting adventures on Bygone Island and here are 7 episodes featuring Team Sonic, (Sonic, Tails, Knuckles, Amy and Sticks) Boom Eggman and the Modern Team (Sonic, Tails, Knuckles, and Shadow) and Modern Eggman. There will also be some other characters included.
