Eggman ship

Robotnik's Eggmobile from Sonic the Hedgehog 2

The Eggmobile is Dr. Eggman's personal hovercraft and main method of transport. It is a round, single-seat vehicle with short, stubby wings and a black dome for its underside. While it might not qualify as a mecha in its own right, the Eggmobile is fully customisable and can be outfitted with a vast variety of tools and weaponry. It is also designed to interface with Eggman's various mech armatures to control them. Eggman has built several Eggmobile models over the years that vary slightly in appearance but all serve the same functions.

Sonic The Hedgehog (2006) - Eggmoblie

The Eggmobile from Sonic '06.

The Eggmobile that appears in the Sonic the Hedgehog '06 video game differs considerably from previous models. This one does qualify as a mecha in its own right as it has two robotic arm pods that can lift heavy objects and attack enemies. The arms' fingers can fire laser beams. This Eggmobile model is larger than the others and has its own small deck, meaning that this vehicle can carry more than one person. It has no seating other than the pilot's chair, however, and there's no guarding to prevent passengers from falling out of the craft in mid-flight.
