Archibald Grims is a fictional character in the Super Robot Wars series. He has appeared as an enemy character in Super Robot Taisen: Original Generation 2 and Super Robot Wars Original Generations.
A cruel, bloodthirsty terrorist, 34 year-old Archibald Grims was the man involved in the Elpis Incident, which took the life of Elzam V. Branstein's wife, fueling the Branstein family's anger towards him. Following the incident, Archibald went into hiding, and reappeared six months after the L5 Campaign, now part of the Neo Divine Crusaders, under the commander Colonel Van Vat Tran as a Major. According to Archibald, his clan, the Grims, comes from an aristocratic background, rich in their influence and power to their nation's government. However, due to an altercation with the legendary Chōkijin, his family lost all their wealth and fled from the face of the public, for fear of shame. As such, Archibald has developed a strong resentment to the Chokijin.
Archibald's merciless, relentless acts of terrorism would garner him the attention of the Original Generation cast, especially Raidiese F. Branstein, who swore to kill him for bringing much sorrow to his family. During Operation Plantagenet, Archibald would defect from the Neo Divine Crusaders and side with the Shadow-Mirror, knowing they would be the ones who can bring him the carnage he so desires. His last stand occurred in the Earth Cradle, having been driven into a corner by the Branstein brothers. As he attempts to escape, the brother's team up and finish him off with their final attacks.
