Profile
The Second Form of the Gundam TR-1 “Hazel-Rah” is equipped with two units of the G-Parts “Hrdudu.” The Hrdudu, developed as a set of enhancement parts for the Hazel, is designed to connect not only to its backpack joint, but also to its multi weapon latch and the side armor of its waist section. This form is equipped with a total of four binder-like wing units, and the functions of the upper and lower pairs are standardized, with two thruster wing units on the backpack for propulsion and two claw wing units on the waist to carry and control weapons. The machine’s operating efficiency is thus raised to its maximum limit.
The Hrdudu’s nose sensor unit can also be used as a connector for shield boosters. This makes it possible to attach two shield boosters to a single one of the mobile suit’s arms.
Technical Notes
By this point, the RX-121-1 Hazel Custom has been repainted in official Titan colors and equipped with the same optical sensor unit and foot thrusters as the Advanced Hazel. The two machines can still be distinguished by their distinctive booster pods, and the fact that the Hazel Custom’s waist armor is painted the same dark blue as its chest.
Hazel Rah Second Form with Booster

This configuration of the Gundam TR-1 “Hazel-Rah” Second Form is equipped with the booster used by the ORX-005 Gaplant. By orienting the thrusters of the Gaplant booster, the four wing units, and the two shield boosters in the same direction, it can achieve tremendous thrust. This could be described as a cruising form which places an emphasis on acceleration, rather than general-purpose combat capability as a mobile suit.
With the long cruising range and powerful acceleration provided by the Gaplant booster, the Hazel-Rah can perform independent attacks over ranges that would normally be inconceivable. As a result, it can use its acceleration for hit-and-run tactics and carry out special operations such as raiding attacks deep into enemy territory.
