OVA
Description
Sonic Bomber is an Autobot Powered Master who serves as the energetic and happy-go-lucky second-in-command to Supreme Commander Dai Atlas. He demonstrates deep respect and admiration for his leader, and though brash and cocky, he understands when to follow orders. As an Attack Staff Officer, he transforms into an aircraft resembling the SR-71 Blackbird and can also convert into a Micromaster base. His abilities include generating concussion waves through supersonic flight to eliminate enemies, though he cannot fly in space. Alongside Dai Atlas, he commands aerial dogfights, wielding his primary weapon, the Vulcan Shot rifle.

He is partnered with the Micromaster Sonic. His technical specifications are: strength 9, intelligence 10, speed 10, endurance 9, rank 9, courage 10, firepower 10, and skill 10, totaling 77 points.

Sonic Bomber combines with Dai Atlas to form Sky Powered, and with the further addition of Roadfire, they form Big Powered.

In the Japanese Generation 1 cartoon continuity, Sonic Bomber and Dai Atlas, as space explorers, rescued the severely injured Victory Saber after the destruction of planet Feminia. They later intercepted Decepticon forces on Earth, defeated them, and secured the Zodiac energy source, leading to Dai Atlas becoming the new Autobot Supreme Commander with Sonic Bomber as his deputy. During Evil Spirit General BlackZarak's attack on Earth, they fought to rescue their captured comrades Landshaker and Sky Hyper. Sonic Bomber defeated Dinosaur General Trypticon using his "Meteor Drop" attack, involving a head-butt with the pointed structure on his head.

When Metrotitan attacked the Lunar Zone Base, Sonic Bomber was occupied by the Metrosquad and unable to prevent others from being frozen. Freed by Roadfire's arrival, he welcomed him as a new ally. The three Powered Masters attempted a "Triple Powered Attack" against Emperor Violengiguar, which failed, and then combined into Big Powered to pursue him after he stole the Zodiac and took hostages. On the Tenth Planet, Sonic Bomber engaged and destroyed one of Violengiguar's aspects, Iguarn, in an aerial battle. After Violengiguar transformed into a phoenix-like entity, the Powered Masters, enhanced by Zodiac energy, combined into Big Powered and destroyed him with the "Rainbow Powered Attack," reforming the planet into a habitable world.

In the Legends comic, a backstory reveals that four million years ago, Megatron created Sonic Bomber, Dai Atlas, and Roadfire as the Poweredrons, designed as space pioneers to establish energon-producing colonies. Upon discovering their work harmed innocent life, they rebelled, evacuated Cybertronian civilians to the secret colony Paradron, and joined the Autobots as the Powered Masters.

In 2035, the Powered Masters were ambushed on the Tenth Planet by Violengiguar, who decapitated them and possessed their bodies. The entity's aspect, Lenger, took control of Sonic Bomber's original body. Wheeljack and Perceptor used the resurrection power of the Tenth Planet to spark the trio into new Headmaster bodies. Without their original Powered Engines, they were initially outmatched by their possessed former bodies. Later, with help from Topspin and Twin Twist, they reclaimed their Powered Engines and fought against Violengiguar's forces, including Unicron Neo (Dark Nova) and the Star Giant.

During the conflict with the Star Giant, Sonic Bomber, defending his daughter and others, fired upon it and was seemingly destroyed but emerged unscathed, wielding a Zodiac energy shard. He later helped undo the damage caused by the Star Giant across Zone. The Powered Masters used the Ultra Powered Combination to destroy the Star Giant and later used their powers and the Zodiac to restore the Legends World.

In the Dreamwave Generation 1 continuity, Sonic Bomber was part of a crowd that heckled Prowl during a public address after Shockwave's government was toppled.

In the 2019 IDW continuity, Sonic Bomber, along with Dai Atlas and Roadfire, intervened in a conflict between the Thraal and A'ovan on the third moon of Na'conda. The A'ovan refugees who relocated to Cybertron held these "Three Saviors" in high regard.
