|Gallery||Since the age of ten when he blew up his parent's garden shed, Dr. Thadeus Peabody knew that he was destined to be an explosives scientist. He relishes the chance to further dispel academic stereotypes by running amok with an automatic weapon.|
Dr. Peabody made his first appearance in TimeSplitters 2, appearing in the Atom Smasher Story mode mission several times as an explosives expert/scientist under Khallos' employment. Despite this, he will still disarm the bombs that Khallos has planted with little coercion. Outside of Story mode, he appears in several Arcade League challenges and a bot set.

However, he makes several appearances in the Arcade League (more than the previous game), as well as a bot set.
