Delroy had no idea of the source of his new powers, thinking that the teachings of the Triune had simply unlocked his superhuman potential.

[14] Soon after, Garrett also helped the Avengers battle Lord Templar and Pagan at the dedication ceremony of a new Triune Understanding building.

[15] Jonathan Tremont publicly blamed the Avengers for the destruction,[volume & issue needed] and then covertly set up a smear campaign against the team to suggest they were religiously intolerant and racist.

[17] 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.

Delroy saw that his teammates were good people and became an eager and willing team member, even refusing to attend Triune functions if it conflicted with his schedule with the Avengers.

[volume & issue needed] During Kang the Conqueror's war on Earth, a being of immense power entered the Solar System.

[18] With Triathlon now in control of the pyramid, the Avengers then returned to Earth and ultimately defeated Kang and the Scarlet Centurion in their bid to take over the planet.

Following Kang's defeat, Triathlon dissolved the pyramid's remaining energies to prevent it being any further threat, subsequently sacrificing the last of his power to restore the 3-D Man and his brother to their independent forms.

[volume & issue needed] When the Avengers later reorganized under a United Nations charter, Triathlon left the team along with some other members.

[19] During the Civil War storyline, Garrett re-emerged as a member of Captain America's Secret Avengers, declaring his stance against the Superhuman Registration Act.

[22] During the Secret Invasion storyline, Delroy arrives in Hawaii and is greeted by Point Men team members Star Sign and Paydirt.

The Devil-Slayer uses his Shadow Cloak to teleport Delroy to Camp Hammond, where he announced to everyone assembled that the Initiative has been infiltrated by Skrulls.

Mid-flight, the Quinjet is affected by the virus the Skrulls used to infect all Starktech systems, and the 3-D Man crashes somewhere in New Mexico.

[28] Delroy leaves the Initiative,[29] noting the hostility of Red Nine, Annex, Geiger, Batwing, and Prodigy over the Crusader's shooting,[volume & issue needed] and joins Ryder to hunt for any Skrulls still hiding out on Earth.

[32] During the Secret Empire storyline, Garrett is shown to be among the superheroes on the run following HYDRA's takeover of the United States.

[47] He only appears around the start, where he voluntarily stays at the Mansion to monitor events as he claims Yellowjacket and the Wasp are more experienced.
