Captain David D. "Dave" Dubosky, aka Countdown, is a member of G.I. Joe. Serving as the Joe team's resident astronaut, Countdown is an expert pilot and electronics engineer, able to fly an F-16 with one hand and repair broken instruments with the other. Despite these incredible abilities, the rest of his teammates see him as incredibly boring.

Unbeknownst to his fellow Joes, Countdown is secretly a Dire Wraith in disguise, with the Wraith becoming an agent of the Earth Defense Command.


When Rom landed on Earth, Dubosky infected the lone survivor of a military unit that had borne witness to the Space Knight's arrival. Dubosky met with some of his former G.I. Joe teammates to hunt down the Space Knight. Earthfall: Part One

Dubosky later found and retrieved Darby Mason. When Dubosky questioned her about Rom, Mason remained coy about the details, unsure of whether to trust him. Dubosky gave her a special gun and phone to protect herself and get in contact with him. Mason later used that phone to report to Dubosky that she had found Camilla Byers and Rom. Earthfall: Part Three

At the base, Dubosky reached out the overeager Leonard Song and brought him to see Rom trapped in a dimensional binding prism. When Darby freed Rom however, Dubosky told Song to watch her while he went to confer with the Wraith growing within Byers. Pleased with the progress of its gestation, he "fled in terror" from Byers. Earthfall: Part Four

While conferring with Scarlett and Director Manheim, General Colton recalled Agent Dubosky's report about Rom seemingly executing people seemingly at random in northern California. Secret Raiders TFWikiFavicon.png

Countdown took part in a Wraith mining expedition to Mount Olympus for Ore-13, only to be surprised by G.I. Joe-turned-mercenary Big Ben, whose team was investigating their suspicious activity. In the ensuing fight, the Wraiths killed Big Ben's team, but Countdown dropped his G.I. Joe dog tags. Not long after, the current Action Man, Ian Noble, retrieved the tags from Big Ben and reported this finding to Mainframe in North America, who insisted that Countdown being there was impossible, having spoken to him mere minutes ago.

When Space Knights Orphion and Livia arrived on Earth, Dubosky spoke with D'rge about how the Wraiths should proceed. Reinforcements, Part 2

Dubosky was later called back to Vandenberg Air Force Base to speak to Leonard Song who believed he had found a way to assume remote control of Rom's armor. Reinforcements, Part 3

Surviving the defeat of the Presence, Countdown led the Wraith delegation that attended the meeting within Trypticon. Unicron #5 TFWikiFavicon.png Dispatched to Siberia, Countdown led the attack on a group of Maximals. Ceremony TFWikiFavicon.png
