Gar’s first appearance was in Doom Patrol #99 in 1965. The team came across him by mistake after he inadvertently found his way into their secret headquarters. Gar’s initial reaction to the team was rude, indignant and scrappy as the Patrol attempted to corral him into giving them answers.
Fortunately, he was able to win them over despite the bad first impression. The Patrol went on to step in and help thwart the assassination attempts made on Gar’s life by his guardian, Nicholas Galtry, and eventually Doom Patrol members Elasti-Girl and Mento were able to adopt Gar as their son.
With the Patrol, Gar adopted the code name Beast Boy and began working as a superhero full time. He even attempted to join the Teen Titans, but was told he was too young (TEEN TITANS #6, 1966.) Things progressed in this way for the next several years until tragedy struck and the Doom Patrol was brutally killed in a trap.
Joining the Teen Titans (THE NEW TEEN TITANS vol. 1 and vol. 2, 1980-1996)
Gar resurfaced in the late ’70s as an on-again-off-again member of the short-lived Teen Titans West, but it wasn’t until the formation of the New Teen Titans in 1980 that he really returned to the spotlight.
Gar was one of the first members of the new Teen Titans team, alongside Robin, Starfire, Raven, Donna Troy, and Cyborg. He marked the occasion by announcing in NEW TEEN TITANS #1 (1980) that he was no longer going to use Beast Boy as a code name and would now be known as Changeling.
In TALES OF THE NEW TEEN TITANS #3 (1982) Gar recounted the time he’d spent between super-heroic jobs trying to make it in Hollywood as an actor. Thanks to his green skin, he was able to find a role as an alien in a sci-fi production called Space Trek: 2020. But the production was halted by legal troubles before it could ever come to fruition. To make matters worse, during the course of filming, Nicholas Galtry resurfaced—now encased in a high-tech suit of armor and calling himself the Arsenal. He had tracked Gar down again, and was looking to finally make good on the assassination attempt the Doom Patrol had thwarted so long ago.
While the attack was unsuccessful, it left Gar out of work and adrift until the Titans had re-formed, making it clear just how important the team was in getting him back on his feet.
Re-forming the Team (“The Technis Imperative,”JLA/TITANS, 1998-1999, TITANS, 1999-2002)
In the late ’90s, Gar returned to Los Angeles to attempt to re-form the Teen Titans West and rekindle his acting career until the original New Teen Titans needed his help yet again.
Vic Stone, a.k.a. Cyborg, became infected with a devastating virus that caused his cybernetic body to mutate and go rogue. In JLA/TITANS: THE TECHNIS IMPERATIVE (1998-1999) Vic’s corrupted form is such a threat that it forced the original team to band together and save their friend.
With Cyborg saved and the crisis averted, the group, alongside some new recruits like Argent and Damage, decide to officially re-form—but they simplified the name this time around to “Titans” to help differentiate them from the newer, younger generation of crime-fighters who formed a group called Young Justice.
The reunion is relatively short-lived, however. In 2003, during the TEEN TITANS/YOUNG JUSTICE: GRADUATION DAY event, original Titan Donna Troy was killed by a catastrophic attack from a robotic Superman clone, prompting Nightwing to completely disband the team yet again.
However, rather than retreat from being a superhero entirely, Gar, Cyborg and Starfire decided to combine their efforts and become teachers for the new generations of Teen Titans.
New 52 (2012-2016)
Gar’s first appearance in the New 52 universe took place in an ongoing book called THE RAVAGERS. This was a major reimagination of Gar’s design and the origin of his powers. This Beast Boy was bright red because his powers stemmed from a relationship to an extradimensional power called, appropriately, “The Red.”
The Ravagers behaved a bit like a more rough-and-tumble incarnation of the Teen Titans, but dissolved after 13 issues. This freed Gar up to rejoin the actual Teen Titans in an all-new TEEN TITANS #1 in 2014 where he was returned to his normal emerald-green self and regained much of his pre-New 52 personality.
Gar remained with this incarnation of the team until the end of the New 52 in 2016.
Following the events of DC UNIVERSE: REBIRTH #1, Gar found himself once again called on to join the Teen Titans—but this time, it was by the pint-sized, tyrannical Robin, Damian Wayne, who had plans to overhaul the team in his own image.
Together with Starfire, Raven, Kid Flash and later Aqualad, the team did their best to live up to Damian’s ever-growing list of impossible demands.
But when the Source Wall was breached at the denouement of DARK NIGHTS: METAL, the powers of many of Earth’s metahumans were wildly affected — Beast Boy among them, assuming a monstrous, hulking new form. Together with Raven, Beast Boy joined Nightwing’s newly reorganized Titans to seek out, assist, and when necessary neutralize those metahumans affected by the Source Wall breach. Luckily, Beast Boy would eventually return to his more familiar form after confronting Mother Blood in The Bleed between universes.
