Sonic Riders Series
The team returns in Sonic Riders. Sonic, Tails and Knuckles encounter the Babylon Rogues (a group of thieving birds who ride Extreme Gear) who steal an emerald that the team was tracking. The next day, the three watch an announcement made by Dr. Eggman advertising the Ex World Grand Prix, when Sonic discovers that the Babylon Rogues have entered the race. The trio signs up as Team Sonic and serve as the playable characters in the hero's story alongside Amy Rose. The members of each team develop a rivalry against their respective character. During the course of Sonic Riders, Wave criticized the handling of Tails' Extreme Gear, but this later helped Tails beat her in a race. In a Grand Prix race sponsored by Dr. Eggman, Sonic was just about to win, but was unaware of a bomb on his board. Wave detonated the bomb, causing Sonic to wipe out and Jet to unfairly win. In the Babylon Garden, Team Sonic, the Babylon Rogues and Amy faced off against the Babylon Guardian, and later found out the treasure of Babylon was a Flying Carpet. Before the credits rolled, Sonic gave Jet his box back, seeing as the Rogues needed it more.
Sonic Riders: Zero Gravity
In Sonic Riders: Zero Gravity, Tails received a news report of MeteorTech Robots going berserk. One of the berserk robots attacks Sonic and company, who proceed to chase it. The team later finds a circular stone which was later revealed to control gravity. The team arrives at ruins, and Knuckles proceeds to examine it. On closer inspection, Knuckles infers that the ruins spoke of a "Lightless Black". Later, as Team Sonic and Amy meet up, the Babylon Rogues arrive and demand Sonic to hand over the Ark of the Cosmos, which was the circular stone that Sonic, Tails and Knuckles found. The team then collects the Arks of the Cosmos and lets Jet keep them as Sonic has no need for them. However, a MeteorTech Robot steals the Arks, and Team Sonic and the Babylon Rogues proceed to defeat the robot and retrieve the Arks before they get sucked into the massive black hole. Later, Tails talks about the ruins' message to Sonic and Knuckles, telling them that it was a warning about using the Arks. The Rogues then appear and the two teams race off.
