Have you ever heard the saying "shoot first, ask questions later"? Well, Groundbreaker is kind of like that, only without the "ask questions" part. If patience is a virtue, then Groundbreaker is in the fastlane straight to the Pit, and that's the way he likes it. Groundbreaker is always the first in line, the first to engage the enemy, the first to open fire and usually the first to screw up. But from Groundbreaker's point of view, whoever comes in first is the winner and what you win doesn't matter, just as long as you come in first.
- French name (Canada): Explosol
Marvel Comics continuity
A member of Fortress Maximus's crew aboard Steelhaven, Groundbreaker volunteered for the synthoplasmic conversion process Optimus Prime had stolen from Scorponok, transforming him into an Autobot Pretender. With Optimus Prime coordinating the Pretenders' first battle with the Decepticons, Groundbreaker and his teammates easily overwhelmed the opposing force.
IDW Comics continuity
Groundbreaker is stationed on board the Autobot Orbital Command Hub, eagerly awaiting the call to battle.
Later he, Cloudburst, Landmine, and Waverider were sent to investigate the Benzuli Expanse, but discovered that any probes or drones entering the area immediately ceased to function. After reporting this to Jetfire, he volunteered them for the Pretender process as a means of safely entering the expanse.
Cyclonus was later patrolling the Benzuli Expanse with Galvatron to look for those who would disturb the Expansion. Upon spotting Cloudburst's ship, Cyclonus called "dibs" and Galvatron happily let Cyclonus attack the vessel.

- Accessories: Electron Assault Rifle, blaster, blaster base/wings, belt, helmet, 2 shoulder pads (left & right)
- Groundbreaker transforms into a Cybertronic racing car, with a large spoiler/gun assembly mounted on top. This parts serve as a kind of crossbow-looking weapon for his Pretender Shell. Similarly to Sky High and Splashdown, he has an animal design for his shell chest panel. It's like, a tiger's face on his chest or something. It freaked the crap out of me when I was a kid.
