Following the overwhelming success of the prototype Z-01 Lancelot during the Black Rebellion,
the Holy Britannian Empire sets about creating a new mass production model inspired by it. In order to test
the viability of such a machine, the Britannian engineers first create an early trial type, dubbed the RPI-212
Vincent. The Vincent combines elements of the Lancelot and its sister unit, the Z-01b Lancelot Club, and scales
them back to more economical levels while retaining excellent performance. In addition to slash harkens and
lance-type maser swords, the Vincent has a unique weapon called the needle blazer. This device, a development
of the Lancelot's own "Blaze Luminous" maser shield, emits a short-range blast of focused energy that can
punch right through enemy armor with devastating effect.
At this early stage of development, the Vincent
lacked a set color scheme, and each individual unit was colored to its pilot's tastes. The first Vincent
unit, a pre-production model painted gold with red accents, is piloted by Britannian assassin and Geass
user Rolo Haliburton, who at the time uses the name Rolo Lamperouge in order to keep a close eye on
Lelouch Lamperouge, formerly known as the rebel leader Zero. A second Vincent, painted metallic white
with purple accents and officially designated the RPI-212A Vincent Commander Type, is piloted by Gilbert
G.P. Guilford when he attempts to thwart the Black Knights' plan to kidnap Area 11's new Viceroy. Though
Rolo defects to the Black Knights and Guilford's unit is destroyed in its first battle, the Vincent is
considered proven, and Britannia creates a full production model, named the RPI-212B Vincent Ward. Rolo
uses his Vincent in service of his adoptive brother Lelouch Lamperouge, AKA Black Knights leader Zero.
However, during Lelouch's massacre of the Followers of Geass in China, Rolo's Vincent is badly damaged by
the Siegfried, and is subsequently scrapped.
