Egg Scrap Mech is the boss of Oil Desert Zone in Sonic the Hedgehog 4: Episode II. It takes nine (console) or five (mobile) hits to defeat.


Inside a large oil drum, Eggman uses an electromagnet to assemble a huge mech out of scrap metal. The fight begins with the mech climbing the inside of the oil drum with crates falling onto Sonic and Tails. Each falling crate's proximity is indicated by an arrow pointing downards which changes color as it is approaching closer Some of the crates contain spikes which pop out at certain intervals and some explode after a countdown. After receiving enough hits, the mech climbs out of the drum and Sonic and Tails must follow it with the Copter Combo. Afterwards, the mech will jump around the background a few times before finally jumping onto the ground in attempt to stomp Sonic and Tails. The player must dodge and quickly use the Rolling Combo to hit its feet before hitting Eggman's cockpit one last time.


  • The way the crates fall in this boss fight is similar to various puzzle games.
  • If the crates fall onto Tails, he will die although this does not happen with Sonic (as long as he has Rings).
