The Resident Evil games may be full of terrifying monsters, but none might be as persistent or relentless as Duolingo’s mascot, Duo the green owl. As he constantly reminds users to complete their language lessons, almost haunting them, the official Resident Evil Portal account posted a crossover nobody expected.
我々の新しい生物兵器だ。
行け。語学学習を世界に拡散させろ──。@Duolingo_Japan#REBHFun pic.twitter.com/IzmY5k3ddu— 【公式】バイオハザード / RESIDENT EVIL PORTAL Official (@REBHPortal) August 2, 2025
„Our new biological weapon. Go. Spread language learning to the world,“ the translation reads (via Automaton).
The playful exchange between Resident Evil Portal and Duolingo Japan’s Twitter account started off already wild, showing a muscular version of Duo replacing the T-002 Tyrant from the original game. Duolingo Japan responded with an edit of its own, placing Duo in the role of the T-00 Tyrant (Mr. X) from Resident Evil 2. Given Mr. X’s reputation for relentlessly chasing players, fans then understood the assignment.
