Fiction
Legends comic
Groundbuster was one of a few Micromasters who were caught in a plasma energy accident when the Autobots experimented with Energon Z. This changed them into Targetmasters, LG-EX Big Powered Prologue Part One and they partnered with larger Autobots, adopting the moniker "Mini-Cons" in the process. Partnered with Tailgate, Groundbuster would use his claw mode to help his partner defuse bombs. Tailgate/G1 Mini-Con Chapter During Tailgate and Swerve's battle with Trypticon in 2015, Tailgate used Groundshaker to pluck Swerve out of a hole in the ground, then revealed his weapon's true identity as a tiny robot to Rattrap in order to make the rat feel better about his own small size. Bonus Edition Vol. 8 Groundbuster, Tailgate and their allies eventually defeated Trypticon. LG-43 Trypticon Project Chapter
When Unicron Neo attacked the Z Planet with Violen Jiger, Groundbuster leapt to the planet's defense and gave Roadfire access to his weapon mode. LG-EX Big Powered Prologue Part One
Toys
Legends

- Legends "Groundshaker" is a redeco of his Generations toy in a much darker teal, a result of being gang-molded with Tailgate. Tailgate and Groundshaker were sold exclusively in a two-pack with Swerve and Phaser.
Notes
- "Groundpounder" was also considered as a trademark-friendly name for the Thrilling 30 incarnation of Neutro before they settled on "Groundbuster".[1]
- Amusingly, the 2015 Robots in Disguise Decepticon Groundpounder also suffers from this disconnect, being named "Groundpounder" in fiction and "Groundbuster" for his toy.
Foreign names
- Japanese: Groundshaker (グランドシェイカー Gurandosheikā)
