Fighting Fefnir, known in the Japanese version as "Tōshō" Fafnir (「闘将」ファーブニル 「Tōshō」 Fābuniru?, Tōshō literally meaning Fighter General or Valiant Commander), or simply Fefnir, is a video game character in the Mega Man Zero video game series. Fefnir is the leader of Neo Arcadia's Scorched Earth Squadron (Jin'en Gundan, literally "Army of Ash Flames"). Fefnir's schematics were based on that of Mega Man X's capabilities of ground combat by earth and fire. He is one of the Four Guardians (四天王 Shitennō?, translated as "The Big Four" in Japan) designed to work for Neo Arcadia and clean up pollution from previous wars. Fefnir wields two arm cannons, named Sodom and Gomorrah (ソドムとゴモラ Sodom and Gomorrah?). He was fiercely faithful to Master X and oversaw a pupil, Anubis Necromancess.
