Knight Gundam (also known as Kishi Gundam) is one of the titular mobile suits of the SD Gundam Franchise, which started with SD Gundam Gaiden. Unlike the samurai-inspired Musha Gundam, Knight Gundam is based on a more western style of herioc fantasy.
A non-SD version, designed by Hajime Katoki, would appear as a secret character in Dynasty Warriors Gundam 3. This version appears sentient, and is voiced by Yasunori Matsumoto in Japanese, or by Lucas Gilbertson in English.
