This unit is based on the RX-78NT-1 "Alex" with major modifications. The RX-78NT-1 ended up in storage at Luna II, having sustained severe damage dueling with the Cyclops Team's MS-06Z Zaku II Kai at Side 6 near the end of the One Year War. In 0084, the Augusta Newtype Lab utilized this MS for Cyber Newtype experiments. Following the facility's shutdown ownership of the unit was transferred to the Ronah family, who lent it to Buch Junk Inc., where it was heavily modified to become the AN-01 "Tristan". Based on the Alex, the unit has several similarities to the original MS, such as integrated gatling guns in its forearms. That aside, most of the parts are new. It's backpack has also been swapped to one with moveable thruster arms, similar to the one seen on the Gundam MK-II. Records state that the MS was used by the private military Birnam, and was capable of docking with an armed base.
