Baymax was introduced in Disney's 2014 animated film Big Hero 6, adapted from the Marvel comics team of the same name, and voiced by Scott Adsit with a calm, robotic delivery. Short lines from the film were later clipped and shared online as reaction sounds on social video and soundboards. This oh no clip became popular because Baymax expresses worry without alarm, making it reusable for everyday mishaps rather than serious danger. It remains in use as a gentle alternative to louder, more dramatic reaction sounds in edits and memes.
