Dragon Ball Xenoverse 2 offers a massive roster of fighters from across the Dragon Ball multiverse. However, grinding through the lengthy story mode, tedious Parallel Quests, and RNG-heavy Expert Missions to unlock every single character can take dozens of hours.
This happens if you attempted to unlock DLC characters that you do not own, or if your save editor version is outdated. Restore your backup save file and try again without checking the DLC boxes.
A common point of confusion is whether a save editor can unlock DLC characters without purchasing the add-on packs.
