The Collision Chaos boss is the second boss encountered in Collision Chaos of Sonic the Hedgehog CD, piloted by Dr. Robotnik.


Dr. Robotnik sits in his Egg Mobile attached to a weak blockade at the top of the screen, but he hardly does much except drop a few bombs down while the player is thrown around inside the pinball section (which are harmless if curled into a ball). The real challenge here is actually reaching Robotnik's territory, while avoiding traps such as retracting Spikes, Bobbins, and other various traps. At the bottom of the table, above the bottom two flippers, there are three lights and a roller. Touching the roller turns a light on. When all three are on, a platform folds down stopping the player from falling onto the slotting spikes, but touching the roller again resets the lights. If the player follows the correct path of springs, he/she will reach Robotnik, where all that's required is to jump through the blockades while panels appear to make sure the player doesn't fall back down to the pinball section, until reaching the next ground level where the doctor flies away on his Egg Mobile.


  • The only difference between the Good Future and the Bad Future is the color of the landscaping. The boss remains unchanged to its behavior.
