The Egg Hammer Nega is an Egg Mobile mecha piloted by either Dr. Eggman or Eggman Nega in the Sonic Rush video game for Nintendo DS. It appears to be a giant, mechanical snake with the cockpit housed in the head. When the player faces it, the Egg Hammer Mega will rise up from behind the stage platform then attack. It has no weapons other than its head, and will attempt to flatten Sonic or Blaze by slamming its head down or rolling it over the length of the platform. The cockpit dome is its weakness and can be destroyed with eight hits.
