RX-105 Ξ Gundam

The RX-105 Ξ Gundam (aka Xi Gundam, Xi, Ξ, RX-105, pronounced "Ksee") is a mobile suit that appears in Mobile Suit Gundam: Hathaway's Flash.

Technology & Combat Characteristics
After completion of the RX-104FF Penelope, Anaheim Electronics secretly built its update version, the RX-105 Ξ Gundam and sold it to the terrorist group of Mafty Nabeau Erin. Ξ Gundam features a Minovsky Craft unit similar to the Penelope but integrates it into its main frame, resulting in a more sleek design and lighter mass. Unlike Penelope, the Ξ Gundam doesn't transform but deploys a Beam barrier by flipping its chest armour up. The Beam Barrier is a device that creates a conical barrier in front of the RX-105 as it flies through the air, making it more aerodynamic, and allowing it to achieve supersonic speeds in flight. These minor changes give the Ξ Gundam an edge against Penelope in term of performance. Its armaments are similar to the Penelope but it has a larger shield without the built-in particle cannon that provided the Penelope better protection.

History
In U.C. 105, The RX-105 is received by the terrorist group Mafty while being transported from Anaheim Electronics' factory on the Moon to Halmahera, Indonesia on Earth. Mafty used the Ξ Gundam in an attempt to attack a meeting of Federation leaders in Australia. Not only did the Ξ Gundam had slightly superior performance but Rein's recklessness and lack of experience contributed to his loss against Mafty as well. However, Rein eventually got over his pride and lured the Ξ Gundam into beam barrier traps. The traps knocked Mafty unconscious and allowed Kirke to arrest him.
