The Pain Bot makes its first appearances in "Waffles". When Brother Blood wants the Titan's voice code to unlock their armory, he plans to endlessly torture them with the newly constructed Pain Bot. Though Robin, Raven, and Starfire give in, Beast Boy and Cyborg refuse to do so simply because they're playing a game where they can only say "Waffles". This leads to excruciating torture until Brother Blood is too annoyed to continue and forfeits.
