A massive Newtype use mobile armor developed by the Principality of Zeon in cooperation with the Flanagan Newtype Research Institute. It carried an oversized, early experimental Psycommu system, allowing its pilot to control the lethal "bit" remote weapons, as well as two 90° foward mounted mega-particle guns. It was piloted by Lalah Sune.
Appears in episode 9 of Gundam GQuuuuuux where it is called The Rose of Sharon. In the GQuuuuuux universe it was never produced and its Psycommu system and bits went on to be used in the Red Gundam. However, an Elmeth from another universe was last seen underwater and was being resurfaced by Zeon.
In real life (specifically in Japan), it was notorious for its name in katakana to be exactly the same as Hermes (brand), requiring merchandises to have a workaround to it, such as ララァ専用モビルアーマー (Lalah's Mobile Armor).
