2XKO roster leaks, what’s confirmed, and who could be next

2XKO’s roster didn’t come together in a single reveal. It trickled out through a mix of playtests, a datamined list from the first Alpha Lab, and late 2025 additions that matched long‑running speculation. Here’s a clear look at what leaked, what’s now official, and which names still make sense for future seasons.

What leaked for 2XKO’s roster and why it mattered

During the 2024 Alpha Lab, a mineable list pointed to 10 champions being worked on for launch. The work‑in‑progress names were masked, but the ordering appeared alphabetical, which helped narrow possibilities before each playtest. That same window confirmed the core six—Ahri, Braum, Darius, Ekko, Illaoi, and Yasuo—while Jinx was locked in for the next wave.

Fast forward to the closed beta in September 2025: nine champions were playable, including a newly revealed Blitzcrank and Vi alongside the original group. The final “who’s number 10?” moment didn’t stay secret—artwork for the first battle pass featured Teemo, and the game’s official account playfully acknowledged the image. Teemo was then formally added. Shortly after, early access Season 0 brought Warwick, expanding the starting lineup beyond the original ten.

Confirmed 2XKO characters (late 2025)

The table below lists every champion confirmed by the end of Season 0, with their broad fighting‑game archetype and when they became available.

Functionally, this roster hits a broad spread: two bruisers for armored pressure, two all‑rounders for flexible game plans, a dedicated grappler, a zoner, a trap specialist, and multiple rushdown and mixup options for players who prefer momentum and corner carry.

How the early datamine narrowed the next picks

The initial list was notable because it looked alphabetical and included masked entries among known names. With Illaoi and Jinx later revealed in that window, the ordering read as consistent. At the time, that suggested one masked champion between Ahri and Braum, and two between Illaoi and Yasuo. It didn’t outright name anyone, but it constrained speculation to reasonable gaps in the alphabet.

Subsequent reveals filled the 10‑champion launch target without needing to decode every gap. Blitzcrank and Vi arrived in closed beta, Teemo followed shortly afterward, and Warwick pushed the roster to 11 during early access. The practical upshot: the datamine was useful for short‑term forecasting ahead of Alpha Lab 2; after that, the normal cadence of reveals and seasonal additions took over.

Characters often mentioned for future seasons

A few names keep coming up for good reasons:

• Katarina: previously visible in very early Project L footage, which implies prototyping work already happened. Her assassin kit translates cleanly to a tag fighter.
• Jayce and Viktor: prominent in Arcane, with intertwined arcs that fit 2XKO’s emphasis on duo play.
• Lee Sin and Sett: hand‑to‑hand archetypes whose move concepts fit a grounded strike/grapple hybrid or stance‑driven pressure.

None of these are confirmed, but they align with two consistent patterns: strong recognition outside the MOBA and kits that map to clear fighting‑game identities.

Names that looked unlikely in the short term

During the Alpha Lab 2 run‑up, some popular champions appeared unlikely in the immediate pipeline based on how the masked list shook out. Caitlyn and Elise were frequently flagged that way at the time, despite their visibility elsewhere. That was a short‑term read, not a permanent exclusion, and future seasons remain open.

The headline for players is simple: the early leak got the shape and scale of the launch right, the closed beta locked in the nine‑champ core, and late 2025 rounded it out with Teemo and Warwick. From here, expect steady additions rather than another big reveal—2XKO is clearly building a roster meant to grow with each season.
