The ZGMF-2000 GOUF Ignited is best known through its use by ZAFT ace pilots Heine Westenfluss and Yzak Jule. The name GOUF stands for Guardian Of Unity Forerunner. Originally considered as ZAFT’s next-generation mass production mobile suit, the GOUF Ignited ultimately lost to the ZAKU series. However, its high performance ensured continued development, leading to full production when Earth-based combat intensified and ZAKU production reached its limits.
