Color-wise, it also has the usual Egg Mobile grey upper-half, black underside, yellow circle on its front and yellow and black hazard stripes on the sides.

Sonic the Hedgehog
In Sonic the Hedgehog, Dr. Robotnik used this vehicle to attack Sonic when he was passing through Green Hill Zone. In spite of Robotnik's efforts though, his vehicle got destroyed by him in the end.

Battle
The Green Hill Zone boss is the first boss of Sonic the hedgehog. The player fights it at the end of Green Hill Zone Act 3.

Boss guide
In Green Hill Zone Act 3, the player will arrive, after climbing a steep hill, in a wide empty area at the end of the Act. Robotnik will then arrive on his Egg Mobile from the right side of the boss arena, initiating the boss battle.

The boss fight with Robotnik in his Egg Mobile is relatively simple. Right from the start, Robotnik will hover above the arena three times, out of the player's reach. Robotnik will then slowly descend to the surface, which is the only time where the player can hit him with the Spin Jump. Meanwhile, Robotnik prepares to charge into the player, before flying quickly across the arena and off-screen. He then repeats this pattern (albeit in an opposite direction each time) until the player defeats him.

In the Game Gear version, this boss fight is even easier, as Robotnik is left vulnerable to attacks at all times, even as he flies above the arena. Once Robotnik is defeated after taking eight hits, he will flee, allowing the player to open the Capsule and complete the Zone in doing so.
