NetEase’s official Marvel Rivals site posted Dev Vision Vol. 21 for Season 10: Butcher’s Blasphemy, arriving September 11, 2026 (UTC). Creative Director Guangguang and Lead Combat Designer Zhiyong walk the season’s hero, map, events, costumes, and balance plans in the broadcast package linked from that diary. This desk is treating that first-party page plus the Dev Vision stream as the lock—not Polygon or Game8 alone.
The season’s roster addition is Gorr the God Butcher, framed as a melee-centric Duelist built around All-Black the Necrosword. Reliable recaps of the same broadcast describe morphing blade forms (including longer scythe swings), Black Berserker summons after takedowns, and map mobility tools such as Symbiote Assimilation. Those kit details are secondary color drawn from outlet write-ups of Dev Vision; the primary claim here is that Gorr is the Season 10 hero and a Duelist, timed to the Sep. 11 UTC season gate.
Multiple recaps also note that Gorr is the only new hero in Season 10. Guangguang’s explanation, as reported, is a bandwidth shift toward later Path to Doomsday event modes (Phases tied to upcoming Avengers movie windows) rather than shipping two heroes at once. Season packaging points to a new Domination map, God Quarry, with outlet timing around September 24, 2026, plus a wide balance pass—Strategist ultimate energy conversion and other roster tweaks called out in coverage—and ranked-system changes for higher brackets. This post does not invent patch numbers, percentage nerfs, or ban-vote UI details beyond what first-party framing supports.
For U.S. readers, the hook is a dated live-service season with a major Marvel villain joining as a day-one roster unlock—not a film/TV beat (Watch Me Bro owns movie coverage). Pre-season roster theater around Loki being marked unavailable in trailers is flavor from secondary outlets; we are not filing a separate “Loki deleted” scare post. No clone of older Marvel permalinks. Related live context on the games desk includes our GTA 6 PS5 Midnight EST unlock report for the broader fall calendar, not as a crossover.
