Gracchus

The Gracchus is a Knightmare Frame developed by the tributary sub-empire of Euro Britannia. It's used primarily by the Knights of St. Michael and is one of their strongest Knightmare Frames.

Operational History
The Gracchus is the improved version of the KMF that lost the competition for the Sutherland successor to the Gloucester.

Its armor is decorated with horse-esque design, most notably in the legs

Its arms are able to extend for surprise deadly thrusting attacks.

After it being heavily damaged by the Lancelot it was hurriedly repaired with carbon fiber parts, hence the black color.
