Metal Madness is the first phase of the final boss of Sonic Heroes. After Neo Metal Sonic copies the heroes data and combines it with that of Chaos, he transforms into this twisted metal monster using pieces and components from the Final Fortress. In this form, he is fused to the Fortress and attacks Teams Rose, Chaotix and Dark (in that order) as they try to buy Team Sonic enough time to use the Chaos Emeralds.

After being defeated, Metal Sonic reverts back to his original form and shuts down.
