Blizzard is stacking its 2026 convention comeback with a mix of music stars, actors and gaming personalities across the two-day Anaheim event.
The BlizzCon 2026 celebrity guests lineup is taking shape ahead of the convention’s September 12-13 return to the Anaheim Convention Center, with T-Pain, Simu Liu, deadmau5, Duke Dennis and Khleo Thomas among the names set to appear. Blizzard is also bringing YOASOBI and LE SSERAFIM into the weekend’s musical programming as the company prepares its first BlizzCon since 2023.
T-Pain will join celebrations surrounding the Overwatch World Cup, while Simu Liu is set to compete in the Blizzard Classic Cup StarCraft II Entertainment Match and also appear at the casting desk. deadmau5 will take part in a Diablo-focused panel featuring game developers, extending the crossover between Blizzard’s franchises and celebrity guests with established ties to gaming.
Duke Dennis will be involved in World of Warcraft activations, community engagements and creator experiences on the show floor. Khleo Thomas, meanwhile, has been tapped as a “BlizzCon Insider,” with plans to capture real-time highlights and behind-the-scenes material throughout the weekend.
The music lineup adds another major draw. YOASOBI will perform during BlizzCon’s first-ever Overwatch World Cup halftime show on Sunday, September 13, while LE SSERAFIM will return to the Main Stage as the convention’s closing musical act that same day. The K-pop group previously performed at BlizzCon in 2023.
The celebrity rollout comes as Blizzard continues detailing what fans can expect from the returning convention, including its Opening Ceremony, hands-on gameplay, developer panels, Community Night and a slate of esports competitions. According to the official BlizzCon site, passes have already been claimed, though fans can still look for availability through the public resale market.
Fans who cannot attend in person will still have access to major programming, with Blizzard confirming that the Opening Ceremony, panels and esports action will be available through official livestreams. BlizzCon 2026 runs September 12 and 13 in Anaheim, marking the event’s return after a three-year gap and its first edition staged under Xbox ownership following Microsoft’s acquisition of Activision Blizzard.
