The LRX-066 Tera-S'ono is a Prototype Mobile Armor from the SD Gundam G Generation video game SD Gundam G Generation: Monoeye Gundams. It is an uncanonical Mobile suit of the Universal Century time-line although it was developed in the same time as the Gundam Mark II. It is piloted by Serein Experi.

Technology & Combat Characteristics

Developed as a part of Project Sirene (Siren) by the Flanagan Institution, it was originally unarmed. However incorporated all throughout its design is a massive psycommu system, allowing it to be controlled entirely mentally as well as to cause enemy pilots to berserk. The LRX-077 Sisquiede and LRX-088 Dezpada were developed as guardian units for it. However when the Sisquiede was stolen, the Tera-S'ono was given its own armaments. The mobile armor mode of the Tera-S'ono wasn't a transformation like many mobile suits, but rather a massive docked system much like the Denrobium Stamen and Orchis. It’s mobile armor mode resembled that of the Rafflesia. In the game itself apparently the four particle cannons could be fired as one larger beam, but it is not entirely sure how that translates over to regular specs.

  • Seirene System
A military plan originally proposed by the Principality of Zeon and recovered by the Titans, this project was developed with the aim of using a Newtype machine to perform wide-area mind control via increasing sensitivity to psycho-waves. It was intended to cause loss of rational thinking in enemy soldiers. This system would be installed in the large Tera-S'ono psycho-wave unit. The two escort units Sisquiede and Dezpada correspond to two former Zeon Newtype machines, the MAN-03 Braw Bro and the MAN-08 Elmeth.


The LRX-066 Tera-S'ono is deployed with Serein as pilot, but because the system was unstable, it was shot down by the AEUG. A few units were produced after by the Titans, however, with the loss of Serein, the Sereine System could no longer be used. Although Project Seirene ended in failure, the concept is later seen in the Angel Halo.
