History
After the AEUG successfully stole the RX-178 Gundam Mk-II from the Titans, two of the stolen units were sent to Anaheim Electronics to study, reverse engineer and duplicate their technology. There a group of technical experts created the Gundam Mk-III, which featured an improved version of the movable frame used on the RX-178 Gundam Mk-II . Overall three different types of the Mark III were created. One of these trial units, the transformation-capable RX-272-2 Gundam MK-III "Halpuley", was speculated to have been constructed at Gryps between the Gundam MK II theft and the Jaburo drop operation.
