Technology & Combat Characteristics
Originally the MSN-06S Sinanju Stein developed by Anaheim Electronics as part of the Earth Federation's "UC Project", its movable frame is partly made from psycoframe materials. All of the Gundam-like features in the Sinanju Stein have been replaced with a Zeonic-like design and weaponry, making it reminiscent of the Sazabi.
The boosters were also replaced with large flexible thrusters mounted in a wing-like arrangement on its back. Sporting multiple vernier thrusters throughout its frame, the unit is capable of achieving precise movements and high speeds.
With its overwhelming combat ability, crimson body, and mono-eye sensors, the Sinanju reminds all who see it of the legendary "Red Comet".
The Sinanju piloted by Full Frontal in UC 0096 is actually a modified version of the MSN-06S Sinanju Stein. The data from the Sinanju Stein was used by Anaheim to complete the RX-0 Unicorn Gundam. In UC 0094, the Sinanju Stein was stolen (disguised as a transfer) by the remnants of Neo Zeon, "The Sleeves". The Sinanju Stein was slightly modified into the Sinanju and used as the personal machine of Full Frontal.
