11 Mighty Foes are powerful monsters that preside over the many caverns dotted across the world of Final Fantasy Resonance. Square Enix named them on August 24, 2026 among the game's completionist elements. Defeating one grants magicite, the material used to awaken a Vision, which ties the hunt straight into party progression.

88 Square Enix has named several optional tracks, and each fields a different kind of opponent. The Colosseum runs escalating leagues of fights that pay out items. The Twelve Legendary Arms are sealed pieces of equipment, each guarded by a monstrosity sealed with it. Secret Dungeons are optional high-difficulty dungeons standing apart from the main story. Mighty Foes are field monsters attached to the caverns, and they are the only one of those tracks Square Enix has tied explicitly to magicite. The whole optional layer is indexed at Side Content and Endgame.

1010 One optional opponent sits outside all of those tracks. Square Enix confirmed on September 3, 2026 that Sephiroth can be found and challenged for a special reward, but has not described him as a Mighty Foe and has not tied him to the caverns. He is not a Vision either. He is covered under Side Content and Endgame.

1414 As of October 11, 2026, Square Enix has not published how many Mighty Foes exist, their names, their levels, which grade of magicite each one awards, whether they respawn, or whether any of them sit behind airship travel. Magicite also turns up in dungeon treasure chests and, per a September 28, 2026 Japanese system video, as quest rewards, so the caverns are one of three confirmed routes rather than the only one.
