Caustic is one of the original Legends in Apex Legends, Respawn Entertainment's battle royale game, known for his toxic gas traps and cold, scientific manner. Short voice lines like this 'Yes' have circulated among players since the game became popular, often clipped from gameplay, voice-line collections, and character interactions. Fans reuse the line outside matches because its flat tone works as a meme reaction, a sarcastic confirmation, or a calm response to chaos. Its simplicity and recognisable Apex Legends connection keep it useful in gaming edits and streams.
