Egg Driller

The Egg Driller is a vehicle created by Dr. Eggman.

History
Dr. Eggman first used the Egg Driller to battle Sonic and his allies at the Emerald Hill Zone, and again at the X-Zone. But the vehicle was destroyed on both occasions. (VG: StH2, SA3)

While on a mission to recover his energy refinery from the Naugus Twins, Dr. Eggman followed Axel in his Egg Driller. Unfortunately, a sudden hit from a Dark Gaia Titan nearly made him and his vehicle fall into a lava pool. However, Axel managed to pull them out and Eggman used the Egg Driller to drill through the Dark Gaia Titan. Afterwards, Eggman and Axel rendezvoused with the other Egg Bosses to face the Naugus Twins. (SU: #84, #85)
