Guardian Forces, often abbreviated as GF, are powerful summonable entities in the Final Fantasy video game series. They serve as allies to the player, providing unique abilities and spells during battles. Each Guardian Force has its own distinct characteristics, strengths, and weaknesses, which players can strategically utilize to enhance their gameplay. In the games, players can acquire Guardian Forces by defeating them in combat or finding them in specific locations. Once obtained, GFs can be equipped to characters, allowing them to learn new abilities and improve their stats. This system adds depth to character development and combat strategy within the Final Fantasy universe.
