— Description, Sonic Boom: Shattered Crystal

The Rocko is an enemy that appears in the Sonic Boom series. It is a mass-produced model of Destruction Troops created by Lyric the Last Ancient.


The Rockos are purple robots with gray joints. Their upper body resembles a hunchbacked and bulky humanoid torso with a point where the head should be. On their chest they have a thick neck connected to a large purple eye with a slit-like pupil, green sclera and horned eyelids. They also have round shoulders, thin upper arms, thick forearms with guns for hands and a bowl-shaped pelvis with small rockets on it.

Lyric the Last Ancient created the Rockos in the Robot Facility five millennia ago to help him destroy the earth's lifeforms and conquer it.[1] During an attack on the remaining Ancients however, the Rockos were shut down when Lyric was imprisoned.[1][2] In the present, they were recovered by Lyric after he escaped to search for the Crystal Shards and battle Team Sonic too.

The Rockos can be found in Shadow Canyons and Volcanic Caverns. In gameplay, they constantly hover in a stationary position in midair. While usually idle, they will take aim at the playable character once they spot them before firing two parallel shots that home slightly in on their target. After flying for a few seconds however, their shots will disappear. The Rockos are often placed (sometimes in rows) so the player can cross gaps or reach out-of-reach areas by skipping across the Rockos with the Homing Attack. Also, even after the player manages to destroy a Rocko, another will later respawn to take its place. Additionally, the ninth Toy the player purchases from Q-N-C's Toy Shop will be a Rocko figurine.

After Team Sonic and Shadow defeated Lyric, the Rockos were stopped once more.


Mindless and silent drones, the Rockos are first and foremost unwaveringly loyal to Lyric the Last Ancient, having been programmed to obey his every command.[1] As per their design, they aim to bring down any and all targets.

Powers and abilities

Thank to their small rockets, the Rockos can levitate in midair. They can also fire energy blasts from their hand guns.

Retrieved on 25 July 2014. "As seen in the Nintendo 3DS and Wii U games, Lyric is the last of his kind from an ancient civilization who lived a millennium ago. His race was devoted to peacefully controlling the world’s resources. Driven mad by power, Lyric turned on his fellow Ancients and took control of the resources. Building an army of robots programmed to obey his every command, the deadly snake-like villain set out to destroy everything organic and create a world of twisted metal and robots. However, just before he could successfully take over, he was attacked by the last surviving Ancients and imprisoned forever. With his army shut down and his plans ruined, he waited in prison plotting his revenge. Years passed and Lyric began to give up hope. That is, until Sonic comes across him. Now with his army rebooted, and his plans in place, the only thing stopping Lyric from total victory is Sonic and his friends."
