Sonic Heroes 2

Sonic Heroes 2 is an upcoming video game developed by Sega for the Nintendo Switch and Nintendo 3DS consoles. It's the sequel to the 2003 original, Sonic Heroes, with the characters reprising the same teams. However, upon completion of the main game, players can customize a team with a speed, strength and flight character.

Synopsis
Sonic Heroes 2 begins with the battle against Metal Sonic. You will need to defeat Metal Sonic again with slightly different mechanics but relatively the same style. After Metal Sonic is defeated, the chaos emeralds from Sonic's body land within the stormy sea. This re-creates Chaos. Chaos merges with a weakened Metal Sonic and the two form an alliance.

Each team has a storyline with four different final bosses for each team. The final boss (upon gaining 100% completion in all team modes) will unlock the final boss battle between Chaos Sonic.
