Hurt Bot is a torture machine built by Brother Blood, programmed to interrogate and execute his enemies. It replaced the previous Pain Bot once he abandoned his own creator for the Teen Titans. He appears in "The Best Robin", where he was nearly about to kill the Titans until the Robins came into Brother Blood's lair to save the them.
Unfortunately, upon seeing all the Robins, Brother Blood panicked, and hit a button that said "IN CASE OF ROBINS", sending out Hurt Bot itself, to ward off the Robins. The Robins, all pumped up and ready to take on the threat jumped in to attack, but were simply smashed literally in their footsteps by Hurt Bot’s gigantic hammer. It was only until Super Robin arrived that Hurt Bot was defeated and presumably destroyed for good.
Hurt Bot is nearly identical to its counter-part Pain Bot. The only significant difference is its bulb head, and the word "Hurt Bot" painted on its chest.
- When Pain Bot became loyal to the Titans, Brother Blood presumably built Hurt Bot as an replacement.
