Full episodes of Arcane Season 2 have appeared online just a day after Netflix appear to suffer a major security breach which saw a slew of fall anime published too. Five episodes of Riot Games’ hotly anticipated animated series appeared online ahead of its November premiere date, and following yesterday's stream of leaked episodes from Dandadan, Ranma 1⁄2, and Terminator Zero leaked . Like these shows, Arcane Season 2’s leaked episodes feature burnt-in time stamps, a “For Internal Use” watermark, and annotations for music and sound effects.

IGN reached out to Netflix for comment. Arcane’s leak likely comes as a major blow for League of Legends fans and creators as Season 1 was praised as one of the best video game adaptations of all time . Following its release, Arcane raked in four Emmys , won five Annie Awards, and won The Game Award for Best Adaptation in 2022 .

Arcane Season 2 was announced in 2023 by Riot Games’ parent company, Tencent, during its 2024 Video V Vision Conference. It was later confirmed the second season would be its last . Arcane’s final season appears to pick up right after the first, with Piltover and Zuan rallying their forces for an all-out war following Jinx’s attack on the council.

At the forefront of Piltovers’ forces are Caitlyn Kirraman and Vi, who’ve been tasked with apprehending Jinx, dismantling shimmer manufacturing facilities, and neutralizing devotees of Silko. Piltover’s Finest aren’t the only allegiances at play.
