Pain Bot is a robot created by Brother Blood to destroy the Titans, because "all he knows is pain". He is first used by Brother Blood to threaten Robin, Raven, and Starfire into getting access to Titans Tower. They give him the their voice codes willingly. Then, when Cyborg and Beast Boy show up and do not give him the codes because of their dedication to only saying waffles, Pain Bot tortures them. When Brother Blood has finally had it with the word waffles, he runs away with Pain Bot.
Later, in the episode "Little Buddies" Brother Blood uses Pain Bot again to fight the Titans. Robin tells Beast Boy to "distract Blood by getting your face smashed in." Beast Boy gets the attention of Pain Bot to allow Robin a chance to throw batarang at Blood's controller. The controlled explodes, and Pain Bot is seemingly forgotten and left behind. He is actually taken to the Titans' Tower by Cyborg, and kept it as a "little buddy". Pain Bot seems to not be able to do anything without causing pain, but Cyborg seems to grow very fond of the robot. The other Titans soon discover Pain Bot's presence in the house, they tell Cyborg that he must get rid of Pain Bot, which he reluctantly does, for a time. He soon sneaks the robot back and is confronted by Robin and the others. Citing that they all have "little buddies", some who may be deemed dangerous or evil, the Titans decide to have a fighting match between their "little buddies". Pain Bot eventually beats every little buddy, totalling seven rounds. His 8th opponent is Silkie, who eats Pain Bot in the first moment of the fight.
