The January 14 update arrives with a new Combatant, Narja, alongside her new Partner, Gaya. This duo functions as Controller characters focused on buffing defense-based Combatants to deal increased damage while healing the entire team. Along with these new characters, the update brings new content and events, such as the Spiral Tower of Screams, new Trauma Codes, and numerous login rewards.
Furthermore, the update introduces notable changes, including a new Skip Story button, adjustments to the Simulation wave system, improvements to the Memory Fragment UI, and various other quality-of-life improvements and bug fixes.
Narja will be an off-season character, meaning she will not be released during the next Galactic Disaster season, but rather before it begins. The next season is scheduled to start after her banner concludes on February 4, 2026.

On December 20, 2025 at 10:00 AM UTC, developers showcased all the new content for Phase 3 of the Forbidden Catalyst Season and the roadmap for 2026, which includes balance changes, new characters, and more challenging game modes.
