The EGG-HVC-001 is a vehicle from the Sonic the Hedgehog series. It was created by Dr. Robotnik during the Little Planet incident.



Robotnik's EGG-HVC-001 is the Egg Mobile attached to a mechanized biped containing two inflatable Bumpers (hence the name), along with spikes in the foot area.

The color of the EGG-HVC-001 varies between the Good Future and the Bad Future. In the Bad Future it is red and gray, while in the Good Future it appears pink and blue steel.

Features and abilities

The EGG-HVC-001's arms can move extremely fast, to the point where they can prevent Sonic from hitting the vehicle.


It can be seen that EGG-HVC-001 is very fragile; when hitting it, an arm falls off, weakening it (although it can still move very quickly). Three hits are enough to turn this machine into scrap metal. When one of his arms is destroyed, he remains temporarily immobile, making it possible to hit him twice in a row. Also, it is incredibly slow, making this boss easy to dodge. The machine lacks additional fenders, so if its arms fall off, it is easily vulnerable around it.


In Sonic the Hedgehog CD, Dr. Robotnik built the EGG-HVC-001 when he realized that Sonic was getting into his plans on the Little Planet. The nosy hedgehog confronted the doctor in the vehicle in the Palmtree Panic's Bad/Good Future. However, the EGG-HVC-001 did not last long in battle and was quickly destroyed, while Robotnik escaped in a jetpack.


The EGG-HVC-001 is the first boss in Sonic the Hedgehog CD, found in Palmtree Panic. While in the original version it is only faced by Sonic, the 2011 re-release makes it possible to face it with Tails.

Boss guide

Being the first boss of the game, it will be extremely easy to defeat Robotnik. The battle begins with the player arriving at a small flat field. The EGG-HVC-001 will land to the right side of that "field". Robotnik will walk back and forth across the arena (though not to the left of the screen for player safety), occasionally stopping to charge an attack by swinging his arms back, and pushing forward. This is the best opportunity to attack. When attacked once, the vehicle will lose an arm, making it more vulnerable to attack.

The boss requires three hits to defeat it. The player can then proceed to the Capsule and proceed to the next Round.
