Shortly after G.I. Joe was formed, Doc talked to Scarlett about how Snake-Eyes had lost his face, voice and family due to a recent Cobra attack. He probably felt a bit embarrassed about gossiping when Snake-Eyes and Duke showed up behind them. G.I.

Transformers vs. G.I. Joe
Doc was part of a G.I. Joe strike force that stormed a Cobra hideout housing deadly Creeper bombs. He gave fellow Joe Breaker a field-patch during mission, assuring him that his injuries were non-fatal. Though the mission ran into some complications when the Transformers Bumblebee and Starscream got embroiled in the conflict, it ultimately culminated in Cobra Commander's apparent demise, signaling a victory for the Joes.

G.I. Joe, and the Earth at large, found themselves caught up in a war against the planet Cybertron. Doc was among the many operatives sent to the metallic planet to take the offensive against their opponents. After an attack against the Decepticon city of Trypticon ended with the Joes on the run, they regrouped at Green Zone 0-8-6, their temporary camp behind enemy lines. There, Doc tended to Wild Bill after he stumbled back to camp in the dead of night, badly injured from his confrontation against the Decepticons. Targetmasters
After a confrontation with some Autobots nearly wiped out both the Joes and their opponents, Grimlock showed up at the Green Zone accompanied by Breaker, Jinx, Cover Girl, and Clutch. Grimlock declared a truce between the Joes and the Autobots had been reached, and both factions partied together to cement their alliance. During the celebration, Bazooka munched on some of the foliage that had been created by the Joes' terraforming process. The plant proved to be psychoactive, prompting Doc to ask his hallucinating friend if he was feeling alright.

Doc performed an autopsy on the body of Wild Bill, sadly reflecting on the many missions they'd been on together, when he found a technoactive cube placed inside his friend's chest.

Notes
- Carla "Doc" Greer was originally created for Devil's Due Press's "alternate reality" G.I. Joe: Reloaded series, in which she was a reimagined version of the traditional male Doc character. DDP would later import her into their "mainstream" continuity as Carl's niece, who took his place on the G.I. Joe team (after he died in the original Marvel Joe series). IDW decided to do the same in its third G.I. Joe series, with the small change that their version of Carla was Carl's daughter, rather than his niece.
