RX-121 Gundam TR-1 [Hazel]
A limited production experimental Gundam type Mobile Suit developed by the Titans for their suppression and destruction of Zeon remnants. It took many design philosophies from its ancestor, the Gundam Alex, such as purgable Reactive Armor as well as two large thrusters and defensive features dubbed "shield boosters".
It was developed from the GM Quel and used primarily by the Titans Test Team. In terms of performance it was very in line with another predecessor, the Gundam GP-01 Zephyranthes. Testing and several modifications on the base unit provided the Titans with precious data to later develop the far more advanced Gundam MK II.
