Rotor Walrus is one of the main characters in the Sonic the Hedgehog television series. He is an anthropomorphic walrus and a member of the Knothole Freedom Fighters who fight against the evil Dr. Robotnik. He serves as the team mechanic, inventing reliable gadgets for his team and their missions.

Concept and creation

In an early bible for the series, Rotor was called Boomer. He was stated to be one of Sonic's oldest friends and to have a poor social life. He was stated to like girls, but to get the hiccups when talking to them.[1]

As seen in the Sonic the Hedgehog: The Complete Series DVD box set, a handwritten note can be seen referring to Rotor as "Boomer", suggesting that this name continued late in production.


Rotor met Sonic, Sally, and Bunnie as well as Antoine when they were children. Rotor's calm and friendly temperament made them friends quickly, and his intelligence served the gang of misfits quite a bit as well.

This happy life was not meant to last, however. Sometime after meeting his best friends, Dr. Robotnik's coup of Mobotropolis occurred, and Rotor and the other children were forced into hiding in the forest sanctuary of Knothole. From here, the liberation group is known only as the Freedom Fighters started. This group, thanks to the incredible talents of Sonic the Hedgehog, as well as Sally Acorn's leadership and strategy, Bunnie Rabbot's half cybernetic strength, and Rotor's own mechanical genius as well as the combined talents of many others proved effective against Robotnik, leading to his eventual downfall and subsequent events.


Rotor is on good terms with just about everyone in Knothole. He rarely goes into any confrontation of any kind with any subordinate. This stability seems to be something his fellow Freedom Fighter comrades and best friends cherish during times of change and confusion.

Rotor can occasionally be bashful, particularly when talking to girls.[2]


Antoine Depardieu

In the second season, Antoine would often act as his assistant and mess up his inventions with his clumsiness much to Rotor's charging.

In the Sonic the Hedgehog comic series and ots spin-offs published by Archie Comics, Rotor was the son of Sherman and Georgette Walrus, who came to Old Mobotropolis for new opportunities outside the traditional Walrus Herd lifestyle. What they did not expect was the Great War. Rotor grew up listening to hi father's war stories and was inspired by the tales of the impressive machinery of the war. However, his family would later be torn apart by Dr. Robotnik's takeover.

Sherman fell in the initial resistance. Rotor's mother (pregnant with his brother, Skeeter), were lost in the chaos of escaping refugees. Rotor was among many other children separated from their parents. He soon fell in with a group aiming to stop Dr. Robotnik: the Knothole Freedom Fighters.

Rotor lent his inventor's prowess to the team. But for every success he had some kind of failure - often eith explosive result. This, and his interest in heavy weapons, earned him the nickname "Boomer".

Rotor was a tenacious member of the team and one of Sonic the Hedgehog's best friends. He was eager to join the firefights, which seemed odd compared to his otherwise gentle nature. His analytical thinking gained him a seat on both the Knothole Council during the First Robotnik War and in the Restoration Committee in its aftermath. He also played a role in protecting his herd from Robotnik many times.

During the year Sonic spent in space, however, Rotor's disposition shifted. His zeal for new weaponry put many of his friends in harm's way. Ashamed, Rotor fell upon the kingdom's conviction of shunning firearms, even to the point of contradicting himself on his past actions. He also took a less active role in field operations.

During the destruction of Knothole, Rotor rescued Tails from a collapsing ceiling, but injured his back in the process. He regained most of his mobility but opted to "retire" to a position on the Council of Acorn. When the Naugus-fied council voted to exile Nicole, Rotor resigned out of protest, donned his nanite suit, and became the leader of Team Fighters.

In the reality created by the Super Genesis Wave, Rotor was the son of Tundra the Walrus. Losing his mother at an early age and disliked by his father, Rotor moved to Mobotropolis to seek a new life, only to get caught up in the Eggman Invasion. He eventually fell in with the Freedom Fighters, becoming both a mechanic like Tails and a warrior in the field like Sonic.


  • During the second season, Rotor was drastically re-designed. He became chubbier and the shape of his snout and tusks became smaller. His eyes now had orange irises. His tool belt was now a darker red and started wearing black gloves. Though his personality remained largely the same, he tended to stay behind more often than in the first season.
  • On the back cover of the Doomsday Project DVD, in an episode description, Rotor is mistakenly and repeatedly referred to as "Robot".
