Revision 1

Onion Knight is one of the legacy Visions in Final Fantasy Resonance. Square Enix confirmed the character on August 17, 2026, in a short official video that introduced him as a Vision. He is the most recent Vision to be named.

What Has Been Confirmed

The confirmation is brief and it is all there is. Square Enix says players can battle alongside Onion Knight, resonate with his Vision within the Sanctum of Light, and unleash his abilities in combat. No elements, no role label, no named abilities and no Resonance attack have been published for him.

Series Entry

The producer has described the roster as sixteen legacy Visions, one for each numbered title from FINAL FANTASY I through XVI. Onion Knight is the standard representative of FINAL FANTASY III, so that is the slot the structure points to, but Square Enix has not stated the pairing itself.

How Visions Work

Legacy heroes' vision crystals wait inside the sanctums scattered across the world, and stepping into one lets you revisit a story from the original game before claiming the Vision. Every Vision is earnable in-game with no DLC, each powers a unique Resonance attack, and abilities learned from one stay equippable while a different Vision is active, within the cost limit covered at Abilities and Mastery. As with every Vision, the kit is designed from zero for this game, so nothing from the original title carries over. For the full roster of named Visions, see List of Visions.
