Egg Mobile-D

Drill Eggman
Drill Eggman is the first boss encountered in Sonic the Hedgehog 2 (16-bit) for the Sega Mega Drive. It appears as a giant car with a spiny drill attached in the front. Robotnik will drive the machine back and forth across the screen, not being much of a threat. However on the seventh hit, he will laugh and his drill will fly off the car straight ahead. Once defeated, the machine will bust down, and Robotnik will pilot his Helicopter Mobile away.

Trivia

 * On the Sonic Cafes mobile phone, Robotniks machine appears with a slight amount of more armor.
 * Official art had been made of where Eggman was chasing away little animals in his Drill Mobile.
