Flak is the deep thinker of the Autobot Battle Patrol. A tactical expert, he has single-handedly crafted an enormous "playbook" of maneuvers and scenarios for the Patrol to use whenever in the field and, at Big Shot's discretion, instituted a rigorous training schedule to make sure the entire team is constantly up to date on all his latest plans. Flak is meticulous, some would say downright anal, in his planning, but only because he feels he has to be. Flak respects Big Shot's authority and decisiveness under fire, but recognizes that his commander's lack of lateral thinking can potentially get their Patrol into trouble. Because of this, Flak has taken on the burden of responsibility in making sure Big Shot's military precision always has a military strategy to back it up.
- Japanese name: Powerbomb

Marvel Comics continuity
Flak and the Battle Patrol were given the mission to break into a secure Decepticon complex by their commander, Emirate Xaaron, in order to learn of a new "secret weapon". To his credit, Flak DID ask the Decepticon nicely to step out of the way...before transforming and unleashing his full missile firepower on the hapless 'Con. The joke was ultimately on the Micros, however, as it turned out the secret weapon was them. Lord Thunderwing had leaked word of the new weapon in order to lure some Autobot Micromasters into his web and use their bodies to reverse-engineer the technology for the Decepticon cause. Flak and his teammates fought back bravely, but were ultimately captured. They were dissected by Thunderwing's scientists and, although Roadhandler and the other Micros managed to free them, the Micromaster technology was in fact reproduced by the Decepticons.
Marvel UK future timelines
Flak and Sunrunner were among the Autobots under Rodimus Prime's command when he returned to the future after the Time Wars. Unfortunately, despite Galvatron's death in the timestorm in 1989, the timeline had rebooted itself so that Galvatron still existed in the present of 2009. While trying to rekindle an Autobot resistance movement on Cybertron, Flak and Sunrunner were caught by Galvatron and the Triggercons along with Rodimus, Kup and Arcee. As Rodimus Prime fought back against Galvatron, Flak and the others disabled the Triggercons, and the Autobots fled for safety. The full Battle Patrol were among the 400+ Autobots who escaped to Earth with Rodimus.
Zone OVA and manga
During the attack of the Nine Great Demon Generals on the Planet Zone Base, Flak (or rather, his Japanese incarnation, Powerbomb) could be seen firing his missiles at Abominus, who effortlessly fended them off with his shield, continuing his rampage. Despite Flak’s effort, the Demon Generals succeeded in capturing the Energon Z energy source. As they retreated, Flak and his fellow comrades of the Battle Team Patrol boarded Moonradar’s rocket to pursue them to Earth. There, the Battle Team Patrol, among other Microtransformers, faced off against Trypticon and Predaking, only to find themselves again at the receiving end of the beating. Luckily, Sonic Bomber and Dai Atlas arrived just in time and saved the day.
Later on, Powerbomb could be seen amongst the crowd cheering and applauding the newly appointed Autobot Supreme Commander, Dai Atlas.
Dreamwave comics continuity
Flak was a member of the Battle Patrol under Big Shot's command, but wasn't nearly as loudmouthed as his comrades, Sidetrack and Sunrunner. He and Big Shot were guarding the entrance to Autobase at one point, while their fellow Patrol-mechs were shooing the Hot Rod Patrol away at another gate.
- Battle Patrol (Micromaster Patrol, 1989)
- Flak transforms into a self-propelled, artillery multiple rocket system of undetermined model. The missile battery, being his legs, can pivot up and down due to his transformation jointing, but cannot rotate. In robot mode, Flak is one of the relatively few Micromaster figures whose shoulder joints are not mounted where the elbows would be in most other Transformers, leading to better than usual proportions.
- Battle Patrol Team (Micro Transformer team, 1990)
- Japanese ID number: C-332
- "Powerbomb" was redecoed for his Takara release, predominantly blue with white robot-mode bits. As with the Hasbro version, he was only available in a complete set with his teammates.
- Early versions of the entire Team also used yellow plastic instead of the medium-gray, giving Flak some very bright treads indeed. Later versions corrected this, and the yellow-plastic versions go for considerably more on the secondary market.
Return of Convoy
- Battle Patrol Team (Micro Trailer team, 1991)
- Japanese ID number: C-374
- The "corrected-color" version of the Battle Patrol Team was re-released in Return of Convoy with no alterations. It did come with an extra: Micro Trailer #11.
- Elite Guard Flak (Botcon Exclusive, 2009)
- This version of Flak from the early days of the Great War is repainted from Cybertron Defense Scattorshot with a new headsculpt. Oddly, it is painted in grey tones and not his tradional green. The assumption is that this was done to diferentiate the toy from the recent release of 2008's Universe Overload which is essentially this mold in Flak's color scheme. Which toy was designed first, however, is currently unknown.
