Current Datamines: (Updated 2025/05/14)
This information is based on data found in MY HERO ULTRA RUMBLE itself. Remember, nothing here is confirmation of anything releasing sooner or later, and is subject to change at any time.
So far datamines from UltraRumble.com have been consistently correct with releases. Things found in the past in previous seasons have in fact released in the following seasons.
(Eg. Twice and All for One found prior in Season 2, released in Season 3/4. Mirio and Dabi's Quirk Set found in Season 4, released/releasing in Season 5.)

All Future Quirk Sets! Official Translations for Supported Languages! (UPDATED)
Added to MasterData as of 2024-09-25. Removed from MasterData on 2024-11-20
Previously, the quirk set list Hydros found was only in the variants table of the data, which was only given in Japanese. As of 2024-09-25, the variants table data was removed, but all future quirk set releases have been added to the language master data for all supported languages. Hawks and Present Mic quirk sets are also included.
Note: These are subject to change at any point. The order of these quirk sets is not guaranteed to happen in this order specifically.
Compiled Data for Unreleased Characters & Quirk Sets
This is data compiled from Season 10 assets/files only.
Data compiled from AssetRegistry.bin
, DefaultGame.ini
, UAsset file mappings, MagazineParamTable.json
, DamageParamTable.json
, RoleSlotUniqueSkillParamTable.json
, and in-game voice line files.
This list is NOT a release order list—rather, it is a compilation of unreleased characters and quirk sets discovered in the current public build of the game. Please note: These characters are presumed to be in development based on the use of ID structures identical to those in One's Justice and One's Justice 2, as well as character-specific voice line references directed at them. Typically, new quirk sets are added in pairs, suggesting alignment with the next two seasons of content. However, with the initial emblem list nearing completion, we may begin to see this approach applied to character additions as well.
Based on current data, it is presumed that Neito Monoma (Ch104) will be released in Season 11 alongside the Itsuka Kendo (Ch046) Quirk Skill Set.
Note: This is subject to change at any point. This is NOT confirmation of anything releasing right now.
