Boston Brand is a former circus acrobat who was murdered. The Hindu goddess Rama Kushna took pity on him and gave his spirit the ability to possess living beings to bring justice to others as the superhero Deadman.
In the episode "La Larva de Amor", Robin searches Titans Tower for Silkie and looks under Starfire's bed but instead finds Boston's corpse underneath much to Robin's horror. Raven gets asked by an Underworld boatman for 'Deadman's coins' and a tombstone with Brand's name appears in the episode "Salty Codgers".
In "Teen Titans Go! to the Movies", he appears as one of the attendees at the showing of Robin: The Movie, and as one of the superheroes that got controlled by Slade.
