The Thor 'Is He Though?' meme originates from the 2017 film Thor: Ragnarok, during a humorous exchange between Thor and Bruce Banner. When Banner suggests he might be the 'strongest Avenger,' Thor responds with a skeptical, squinting facial expression that perfectly captures passive-aggressive doubt. This image quickly evolved into a universal reaction template for questioning someone's credentials, skills, or questionable life choices. Its popularity stems from Chris Hemsworth's comedic timing and the relatability of being politely unconvinced by someone else's bragging.
