Antagonist Gundam of Gundam Hathaway's Flash.
The RX-104FF Penelope is actually comprised of two units: the RX-104 Odysseus Gundam and the Penelope Fixed Flight support unit, which contains a miniaturized Minovsky Craft, allowing it to fly within the atmosphere. The support unit itself transforms into a dragon mode when activating the Minovsky barrier around the MS, drastically improving its aerodynamic profile and allowing it to achieve supersonic speed in flight.
Its armaments consist of a beam rifle, two small shields on each arm which contain the beam sabers and small mega particle cannons; vulcan guns and mega particle cannons on the FF unit. It also has Funnel Missiles, remote-controlled weapons guided by the pilot's Newtype abilities and exploding upon impact.
It is piloted by Lane Aime of the Circe Special Forces unit, and designed in real life by Moriki Yasuhiro for the novel; the design was later updated by Fujita Kazumi for the SD Gundam G-Generation series; this updated design has been used for both video games and figures, with Katoki Hajime giving the design another update for the Fix Figuration line (where its parts can be swapped with the Xi Gundam).
