There have been several variations of the Hover Unit, though they all maintained the same overall design and appearance. The Hover Unit's primary design is of an egg-shaped hovercraft with two hatches on both sides near the rear of the craft to allow entry and exit (some models also featuring an alternate roof hatch and loading ramp on the underside). There are two seats for a pilot and co-pilot at the front of the craft, and the cabin can be modified to suit the needs of the mission being performed at the time.
The Hover Unit generally features a two-tone dark grey/black paint scheme, though in "Sonic Racer" several Hover Units had varying colors participating in a race Robotnik was holding as a trap to catch Sonic. Robotnik also had a personal hovercraft which featured a red and black color scheme.
The Hover Unit is used as an attack craft; its typical armament consisting of one or more laser cannons mounted on the exterior of the craft. Robotnik's personal hovercraft was further armed with a missile launcher and cloaking device, which allowed him to escape undetected when several of his plans backfired on him.
The Hover Units were equipped with various sensors for use in patrolling Robotropolis, such as searchlights and Infra-Red sensors for detecting heat signatures of organic intruders (though these could be confused by emissions from power stations within the city, as seen in "Sonic and Sally"). The Hover Units are also shown being capable of flying in space and surviving planetary re-entry, as seen when Sonic and Rotor Walrus commandeer one to escape an exploding space station in "Harmonic Sonic".
The Hover Units serve as the primary means of transport for Dr. Robotnik's military forces, piloted by his SWATbot army. On rare occasions, the Knothole Freedom Fighters were able to commandeer these craft and employ them against Robotnik, either to counteract one of his latest plans or as a covert means of infiltrating his operations.
SWATBot-based Hover Units
A similar-designed vehicle, but yellow/peach in coloration instead. This unnamed unit is a non-flying variant of the Hover Unit that is used in performing repairs and maintenance throughout Robotropolis. This unit employs a series of hovering platforms that allow it to reach its destination almost as fast as the Hover Units. These only appeared in two episodes of Sonic the Hedgehog, one which was used by Sally to sneak into Robotropolis in "Sonic Boom."
In vehicular mode, this unit relies on four wheels for mobility, but it can shift into a bipedal mode, with the axles forming as arms and legs to move about, and the tires serving as ankle and wrist joints. Though its cockpit is designed similarly to its flight-bound brethren, this is smaller on the inside, only large enough to accommodate a single Mobian/Robian driver alone, or presumably runs from an onboard AI. This unit also possesses a laser cannon on the underside as opposed to the roof like the Hover Units.
