WARNING: The following contains spoilers for The Flash Annual #3, by Joshua Williamson, Stephen Segovia, Brandon Peterson, Carlo Pagulayan, Jason Paz, Hi-Fi and Steve Wands, on sale now.
Even since the introductions Green Hornet's Black Beauty and Batman's Batmobile, plenty of superheroes and villains have had their own custom vehicles to get them around while staying stylish over the years. Green Arrow and Speedy had Arrowcar, Spider-Man and the wall-driving Spider-Mobile, the Fantastic Four would pile into the Fantasticar and even Thanos would have his own personally branded helicopter as he scrambled to recover the Cosmic Cube.
And, in The Flash Annual #3, two longtime DC villains got custom vehicles of their own: Captain Boomerang and Deathstroke.
After Digger Harkness learns that he and the rest of his teammates on the Suicide Squad have an outstanding bounty that Deathstroke is keen to collect, he turns to the superhero he knows the best for help: Barry Allen. The Squad tells the Flash that they have their own ripoff of Wonder Woman's Invisible Jet that will let them get to safety and evade Slade. The only catch is that this cloaked aircraft is currently located deep in a desert. Realizing the impracticality of running each of the individual Squad members to the desert, the Flash agrees to transport the team in Diggers' "Captain Boomerang-mobile."
Ultimately, the self-proclaimed Boomerang-mobile turns out to be little more than a cheap, broken down van, despite Digger's obvious pride in his ride. With the Suicide Squad crammed in the van, the Flash drags the vehicle through the desert using his super-speed hundreds of miles to California's Death Valley to get the team back to their hidden aircraft.
However, before the Scarlet Speedster can complete his impromptu escort mission, the ensemble is intercepted by Deathstroke who manages to keep up with a vehicle of his own: the Death Buggy.
It's then that the veracity of Boomerang's story faces heightened scrutiny: the issue uses a narrative framing device of Boomerang being interrogated by the authorities, with the villain quickly establishing himself as an unreliable narrator. The interrogators vocally doubt that the no-nonsense Deathstroke would take the time and effort to brand his ride as the Death Buggy but Boomerang brushes off their questions to continue his story. And, no matter what Slade called his tricked-out all-terrain vehicle, the Death Buddy certainly lives up to the name. In addition to being able to intercept the Flash and Boomerangmobile, the Death Buggy is loaded with a full arsenal that derails the escort and destroys the van, with the Suicide Squad barely escaping from the burning wreckage with their lives.
Fortunately for the Scarlet Speedster and Suicide Squad, Deathstroke's new ride similarly doesn't last beyond this Death Valley Showdown. Borrowing Wolverine and Colossus' Fastball Special, Fin is hurled at the Death Buggy, totaling the armed, armored vehicle and forcing Deathstroke to emerge and face the Suicide Squad and Flash on foot.
Even though the were both wrecked by the end of the issue, this annual adds two new custom supervillain vehicles to the DC Universe, even though Boomerang's rundown van may not qualify, no matter how proud the Flash villain might be about it.
