Technology & Combat Characteristics
The MSK-003 Wagtail II is a custom mobile suit used by Van Asiliaino, a member of the anti-Titans organization Keraunos. The Wagtail II is a further upgrade of Van's previous RGM-79C GM Type C "Wagtail" with parts from other mobile suits. Parts from the RGM-79N GM Custom have been incorporated into the joints and torso, while the head, backpack, and cockpit block have been replaced with prototype parts. The GM Custom parts strengthen the frame, allowing the Wagtail Unit to be operated at its full output. The Wagtail Unit's armor has also been changed to those made of Gundarium Gamma alloy. The backpack is equipped with wing binders featuring numerous thrusters and hardpoints for mounting weapons. The new head features a twin-eye sensor surrounded by a ricochet board. Due to incorporating so many parts from other mobile suits, the GM designation has been removed from the unit's name and it is given a new model number by Karaba.
History
During the Gryps Conflict, the rapid technological advancements caused standard MS design to be inferior, even an upgraded design such as RGM-79C GM Type C "Wagtail" piloted by Van Asiliaino was not able to perform equally with state of the art MS such as RMS-108 Marasai or NRX-044 Asshimar. therefore the GM Wagtail was upgraded with new armor material, RGM-79N GM Custom parts, and various experimental parts resulting the MSK-003 Wagtail II. This Wagtail II was used by Keraunos who joined forces with Karaba, and fought various battle against more advanced Titans MS during the conflict. Unfortunately during the Battle of New Guinea Base it was severely damaged by NRX-044Q Asshimar [Danda-Chakra] and a Marasai. Due to the damage it suffered, the Wagtail II was upgraded with any available parts by Keraunos engineer, such as RMS-106 Hizack backpack, painted green color similiar to those RGM-79R GM II fielded by both the AEUG and Karaba, and the unit was renamed into Wagtail IIex.
In U.C. 0087, the Wagtail IIex participated during AEUG and Karaba joint operation to assault Titans Earth headquarters at Kilimanjaro Base and piloted by Jorn Juliana. During the battle the Wagtail IIex is one of the unit that tried to attack the MRX-009 Psyco Gundam, but its left arm got hit by the MA mega particle cannon. Fortunately the unit was only suffered minor damage and still combat capable and manage to destroy some of the defense turret near the Base, however Wagtail IIex was spotted by a MS-06K Zaku Cannon piloted by Iris Alison and both unit engaged in intense combat.
Due to the skill of Jorn he is able to utilize Wagtail IIex high mobility despite the damage it suffer, and manage to outmaneuver the Zaku Cannon. However when it was almost destroyed the Zaku Cannon both unit was damaged by the Psyco Gundam beam barrage.
