Film series

Sonic the Hedgehog

Following a blackout across the Pacific Northwest that was caused by a massive electromagnetic pulse, Agent Stone accompanied Dr. Robotnik when the latter was sent to investigate the cause of this phenomenon. Arriving in Green Hills, Montana, Stone would "translate" Robotnik's condescending words to Major Bennington for the latter when the doctor asserted dominance over Bennington's operation and began his investigation. Joining Robotnik in his mobile lab afterwards, Stone saw that Robotnik had found a strange footprint and had determined from it that the cause of the blackout was "something else entirely."

Following the trail to the Wachowski house, Stone rushed in there to check up on Robotnik when he got knocked down by Tom Wachowski, who escaped with an extraterrestrial named Sonic, who had extraordinary powers. However, he got reprimanded by Robotnik for not stopping Tom and Sonic as they fled. Before returning to Robotnik's mobile lab however, Stone took one of Sonic's quills with him upon Robotnik's order. Soon after, Stone joined Robotnik and their operatives during their occupation of the Green Hills Sheriff's Department where they monitored Tom's conversation with Wade Whipple. After that, Stone traveled with Robotnik to the Piston Pit, where he assisted Robotnik in interrogating a Roadhouse Thug about the whereabouts of Sonic and Tom. An amazed Stone then saw Robotnik pinpoint the duo's exact location before sending his Badniks after them. After the Badniks were destroyed, Stone made a remark that prompted Robotnik to vent his frustrations on him. However, Robotnik then noticed that the quill Stone was holding was pulsating with energy, prompting the doctor to analyze it. As Robotnik later jammed to music while analyzing Sonic's quill, Stone brought him a latte, accidentally sneaking up on him and scaring Robotnik, who complimented Stone agressively. As the quill was determined to have limitless energy, Stone was ordered by Robotnik to prepare the Eggpod for deployment.


Agent Stone is a relatively calm and level-headed man, which contrasts greatly with his eccentric boss. He is likewise very formal and notably professional in behavior and speech. He is also a quite polite and advocate person, often showing admiration and giving praise to those that amaze him.

Stone has proven himself to be extradordinarily tolerant, enduring Robotnik's physical and emotional abuse and verbal berating of him without showing any more than a rare and quiet exasperated sigh. He is also very subservient, always carrying out the orders of Robotnik no matter how he has been treated by him.

Powers and abilties

As attested by Dr. Robotnik, Stone can make excellent lattes.


Dr. Robotnik

Stone and Dr. Robotnik, from Sonic the Hedgehog (film).

Stone is the assistant of Dr. Robotnik. He is used to Robotnik's antics and understands him better than most other people, although his claims can nonetheless make him question Robotnik's sanity. He is very subservient to Robotnik, taking his physical and emotional abuse and doing humiliating things for him without question. He also seems to genuinely care about or admire Robotnik to some extent as well, like thoughtfully bringing him a latte while he worked and admiring his work to name a few examples, even after being trheatened with violence and being told by the doctor himself that he would never miss him.
