Overview

• Capcom’s Resident Evil Twitter account launched the crossover by dubbing Duolingo’s owl mascot a hulking “biological weapon” on August 2.
• Duolingo’s Japanese account responded by recasting Duo as Mr. X stalking Leon Kennedy and taunting him for skipping his language lesson.
• The exchange culminated in an image of Duo looming before a burning Raccoon City station while vowing to chase players until they played in English.
• Fans have applauded the playful meta-marketing stunt for its clever nods to franchise lore and Duolingo’s new “AI-first” persona.
• Capcom and Duolingo have confirmed that Duo will not feature in Resident Evil Requiem, which is slated for release in 2026.
