Delroy Garrett, Jr. is a fictional superhero appearing in American comic books published by Marvel Comics. Originally known as Triathlon, he is the second character to use the name the 3-D Man. Publication history Triathlon first appeared in Avengers vol. 3 #8 (Sept. 1998) and was created by Kurt Busiek and George Pérez. The character appeared as a member of the Agents of Atlas in 2011. Fictional character biography Delroy Garrett is an Olympic track medalist whose career was derailed when it was found he used steroids. Dejected, Delroy joined the Triune Understanding to restore his faith. Triune leader Jonathan Tremont imbued Delroy with powers stolen from the former superhero the 3-D Man. Delroy had no idea of the source of his new powers, thinking that the teachings of the Triune had simply unlocked his superhuman potential. Delroy became the costumed superhero Triathlon and the Triune's celebrity spokesman. Garrett's first involvement with the Avengers came while he was using the identity of Triathlon; he assisted them in defeating arms dealer Moses Magnum. Soon after, Garrett also helped the Avengers battle Lord Templar and Pagan at the dedication ceremony of a new Triune Understanding building. The battle ended with Lord Templar and Pagan escaping. Jonathan Tremont publicly blamed the Avengers for the destruction, and then covertly set up a smear campaign against the team to suggest they were religiously intolerant and racist. Tremont then had the mercenary the Taskmaster frame a number of Avengers for the destruction of an important Triune building. Tremont then publicly "forgave" the Avengers, which the team grudgingly went along with to avoid further bad publicity. It was during Tremont's media event at Avengers Mansion that the building was attacked by a terrorist. Triathlon aided the Avengers in defeating the terrorist. In the aftermath, Duane Freeman, the Avengers' government liaison suggested that the team add Triathlon as a member to quell the bad publicity that the team had recently engendered. With some animosity on both sides, Triathlon was made a member of the Avengers when their new line-up was announced to the public. At first, Triathlon, although a capable member, constantly complained and argued with his teammates, thinking that they were intolerant and included him on the team only because of the public image. But soon, with the help of teammate Warbird, who told him that he could either go around with a chip on his shoulder
