Whatever Happened to Grimer? is a complete story by Nigel Kitching, Roberto Corona, Nigel Dobbyn and Ellie de Ville. The Metropolis Zone is being attacked by a Metallix and Sonic is no matched for it. The unconscious hedgehog is taken to the Metropolis City High Security Prison, where Grimer hypnotises Sonic into revealing what happened to Doctor Robotnik during their last encounter. He is then taken back to the city and given left with a fake Metallix wreckage, tricking him into thinking he has won. Even the Governor of the prison is forced to co-operate.
