Sonic Riders Zero Gravity ABIS Sphere

Master Core: ABIS is the only boss of Sonic Riders: Zero Gravity. Appearing in the last level, Mobius Strip, ABIS is formed by SCR-HD's transformation within Astral Babylon, twisted under the influence of the "Lightless Black" and the Arks of the Cosmos into this enraged giant. Determined to stop him before all of Sonic's world gets sucked into the evolving singularity, the heroes fly their Extreme Gear into the swirling ruins of Babylon Garden to take down the robot.
