This is quite possibly one of the biggest Mobile Suits that I have ever seen.
Repaired:

The Kshatriya is used by remnants of Neo Zeon called "The Sleeves" and is Marida Cruz's
personal unit. It is first seen in combat against three Jegans during
its trip to the Industrial 7 colony. After being alerted to Londo Bell
forces near around the colony, Marida Cruz uses the Kshatriya to attack
the enemy mobile suits consisting of RGM-89D Jegans, RGZ-95 ReZeLs, and RGZ-95C ReZeL Commander Types in order to give Suberoa Zinnerman
and their ship Garancieres time to escape. The resulting battle ends up
reaching the colony interior and results in severe civilian casualties.
Despite being significantly outnumbered, the Kshatriya manages to
destroy a majority of the mobile suits.

Battle at Industrial 7

Marida later manages to locate Mineva Lao Zabi, but is ambushed by a D-50C Loto and ends up losing her and destroying the Loto. Upon recovering however, she was unable to search for Mineva, as the RX-0 Unicorn Gundam, piloted by Banagher Links,
attacked the Kshatriya and forced Marida outside of the colony. There,
the Unicorn Gundam's Destroyer Mode activated, and the Kshatriya lost
two of its shoulder binders and several funnels in the resulting battle.
Upon the recovery of Suberoa, Marida broke off from the battle and
retreated.

Ambush on Unicorn Gundam

The Kshatriya is seen again during the battle between the RX-0 Unicorn Gundam and the MSN-06S Sinanju,
ambushing the Unicorn Gundam after it entered Destroy mode. Together
with the Sinanju the Kshatriya was able to overwhelm the Gundam and
capture it as it returned to Unicorn mode.

Battle of Palau

The Kshatriya reappeared during the Londo Bell/ECOAS offensive to
take back the Unicorn Gundam. Marida faces off against Banagher, but
Unicorn's NT-D System activates, taking control of Kshatriya's funnels.
Banagher manages to severely damage the Kshatriya and is about to make
the finishing blow when the psycoframes resonate, giving Banagher a
glimpse of Marida's past as Ple Twelve. Banagher takes the heavily
damaged Kshatriya and Marida on board the Nahel Argama.

Aftermath

After the Battle of Palau, the crew of the Nahel Argama began repairing the Kshatriya, thus becoming the NZ-666 Kshatriya Besserung.
