Terminal Velocity is the final zone in Sonic Colours. It unlocks after beating the 6 bosses of the previous zones.
As all the generators are destroyed, Sonic, Tails, and the Wisps start celebrating at Tropical Resort. However, this is short lived, as the resort itself begins to fall apart due to Rotatatron's arm stuck on one of Tropical Resort's 8 Hyper-Go-On Lasers. Sonic and Tails realize it's time to escape, and head for the elevator to the planet's surface. However, once they reach the elevator, they are confronted by Eggman, in the Nega-Wisp Armor. After Sonic taunts the infuriated doctor, he pushes Tails into the elevator in an attempt to stop his buddy getting hurt. Sonic then turns his attention to Eggman, and thus the final level begins.
