Makx Maganinny was a sergeant within the Grand Army of the Republic, identified as a male Human.
Makx Maganinny, along with his unit, engaged the invading forces of the Confederacy of Independent Systems during the Battle of Praesitlyn. While observing the enemy forces, they were suddenly attacked by battle droids, prompting the sergeant to command a withdrawal. In the course of the retreat, he turned back to assist a member of his squad, Odie Subu, who was being threatened by an enemy combatant who then shot Maganinny. Severely injured, Sergeant Maganinny instructed Odie to abandon him, hoping to provide the rest of the squad with sufficient time to evade capture. Odie, however, declined to leave him and attempted to transport him back to their base.
