Using the vastly underrated team Damage Control, Marvel Comics was able to poke fun at rival publisher DC Comics. Fans may know Damage Control from their appearance in the MCU's Spider-Man: Homecoming, but they also have a long history in the comics, where Marvel used them to reference the runaway success of Tim Burton’s Batman.
Damage Control is a unique organization within the Marvel Universe - a construction company that cleans up after superheroes, often using superpowered individuals who prefer an honest day's work to directly fighting crime. Damage Control starred in three different mini-series between 1989 and 1991, and the group has also appeared in line-wide events such as Civil War II. Damage Control has appeared in several animated series, such as Ultimate Spider-Man, and remains a consistent presence in the Marvel Universe, often as the focus of more comedy-oriented stories.
In issue one of 1989's Damage Control vol. 2 (from Dwayne McDuffie and Ernie Colon), Damage Control was bought out by Carlton Industries, and the new owners put an enormous “DC” on top of the building. While it was supposedly short for “Damage Control,” readers could not help linking it to DC Comics' iconic logo, and this became a running joke through the miniseries, as various characters came under the thumb of new corporate masters. With new rules that led to some of Damage Control going on strike, it was strongly implied that the "DC" takeover was a bad thing for the main cast, allowing Marvel to take digs at its main competitor. In issue four, the company is sold, and the giant "DC" is removed. Readers learn that an employee sold it to a "comic book company uptown," allowing Marvel to be even more explicit with the insulting reference. The employee reveals this comic book company made a huge sum off a recent movie, giving them the cash to buy the giant letters.
This is pretty clearly a reference to Tim Burton’s Batman, which was released to critical acclaim and major box office returns a few months prior to the issue’s publication. The movie was not only a hit in theaters, but inspired a nationwide Batman craze, referred to as "Bat-Mania." Furthermore, the film helped elevate the profile of not only Batman, but the comics industry as a whole, and here even Marvel acknowledges DC’s success (after a few issues of implying it would terrible to actually work under DC.)
Damage Control is one of Marvel’s most underrated teams. While they're essential for filling the plot hole of how the world keeps functioning despite ceaseless superhero battles, Damage Control's comedic leaning also allows Marvel to have fun with contemporary issues, including taking some light-hearted shots at DC Comics.
