Told you he'd come back! He always comes back!!
— Spin to Douglas about Springtrap in Mission Mania

Spin Krane is one of the Bionic Soldiers that made up Victor Krane's bionic army. He picked the name Spin for himself because of his ability to spin like a cyclone, a bionic ability that resembles a spinning top.

He is portrayed by Max Charles.


He is the probably the youngest known bionic person to date, taking a title formerly held by Chase Davenport. It is important to notice all S-Series were genetically developed sometime during Douglas Davenport alliance with Krane and, therefore, all are younger than Leo and even the older looking ones might be younger than Spin.

When using his unique ability, his cyclone like spin resembles the Tasmanian devil of Looney Tunes. It also creates a wind draft that makes people around him back away or shake their legs.

He is easily agitated and complains loudly, especially when speaking to others before practice matches or when trying to drive a point.

Leo nicknamed him both Mighty Mouse and Bionic Ballerina due to his skill and personality. Mr. Davenport, in turn, is easily impressed by the techniques Spin displays, promoting him once from beginner to intermediate for showing it, and again to advanced for training it's use over a day.

He did not engage the Davenports in the Rise of the Secret Soldiers, possibly due to his physical age. He was also not seen in Bionic Houseparty, due to being one of the former army members that did not follow Adam to the house at the time. Sebastian most likely signaled him, Bob and other soldiers to the Bionic Island.

At the Bionic Academy, he often picks on Leo Dooley, pointing Leo's faults and competing with him for Mr. Davenport's praises attention. Leo uses him as a scapegoat after damaging the academy but upon seeing Mr. Davenport ignore Spin just as he does Leo, he told his step father it was his fault. Spin in turn convinces the other students to help Leo fix the damage. They become frenemies after this.

He was demoted back to intermediate before Adam Steps Up. Despite being a level over Leo (still a beginner), Spin challenged him for a spar witnessed by Janelle. When Leo is aggressive and nearly hits him with a Laser Sphere, Spin takes advantage of the attack and fakes injury in order to make Leo look bad before Janelle.

His actions towards Leo are shown to be a reflex of his envy towards the slightly older bionic person, a fact evidenced by his attempts to seek praise from Mr. Davenport. He also wants to prove himself to his bionic peers. After Leo got to go on a mission and he was held out due to being too young, he took a page from the older bionic teens' book and went on a mission without letting anyone else know, but he failed the mission and landed himself and Bob into trouble. (Unauthorized Mission).


Spin is the frenemy and rival of Leo. He is very competitive and always tries to embarrass or get Leo in trouble as often as he can. Spin acts very mean to his lower peers due to the fact that wants them to think he is stronger, better, and more superior. He also hates when people calls his unique ability, twirling. However, after Leo blames Spin for damaging the academy, then later tells his step-dad the truth, Spin and Leo are on better terms.

He shares many characteristics to a younger Leo from Season 1. Spin wants to prove himself, especially to Mr. Davenport. To the point he would make the same mistakes Leo did (like going on a mission with no one knowing) in order to get his attention. Unlike Leo, he does this for attention and glory, while Leo mostly wanted to be a part of the team and go to missions with them. Along with his brother Bob, he frequently gets in trouble.


  • Rapid Gyration: Hence his name, Spin can spin at an incredible speed in a cyclone like matter. This ability is probably related to super speed. However, substances like quicksand can slow down and halt his spinning. He can spin almost as fast as Bree can run, as he was able to steal an item from Leo before he could even notice.
    • Speed Digging: As shown in the episode Bionic Rebellion, Spin is able to spin fast enough to break the ground and dig a hole. He used this ability to help Leo escape the anger of the rebelling students. This ability seems to be very powerful but rarely used as Spin seemed worn out from drilling through solid matter.


Season 3

Season 4


  • Spin is most likely a stand in for Terry Perry as Leo's frenemy/rival in the Bionic Academy until Perry showed up on Unauthorized Mission and got hired as Head of Security in the Academy. Subsequently, in Human Eddy, Eddy got imprisoned by Donald in the Academy. Which means Leo now has to deal with three frenemies.
  • He and Bob are the youngest of all the students.
  • He owns a black mobile phone with complete QWERTY keyboard. Probably a Blackberry or a look alike.
  • When Donald tries to name Spin after his own name (as he was doing others), Spin argued against it and told him he wanted to be called 'Spin', he then showed the whole class his unique ability.
  • While he and Leo hate each other, they both stood for one another once. They also got in trouble in all episodes they were featured in the Bionic Academy Arc. However, only Leo only gets in trouble in the first episode, while Spin gets in trouble in the last. However, Adam Steps Up is the only episode where both of them get in trouble.
  • He advanced from beginning (yellow) to intermediate (green) in First Day of Bionic Academy, by displaying his spinning skill at orientation day (Leo argued that he just twirled). The same day he displayed the skill again after practicing for a while and Donald gave him another promotion to advanced (orange) (Leo called it buffing the floor). By Adam Steps Up he had been demoted back to Intermediate, which makes him the first Student to suffer a demotion. In Bionic Rebellion he is demoted again, to beginner, probably because of the mission he and Bob went on in Unauthorized Mission. Of all students, he suffered the most demotions, due to constantly getting in trouble.
  • Spin is similar to Leo from when he was younger.
  • His powers are similar to that of DC's Red Tornado and The Mask.
  • He is the only bionic character to show only one bionic ability.
  • He joins the rebellion in Bionic Rebellion. However, he switches back to Leo's side.
  • It was revealed that Spin was the youngest of all the Bionic Soldiers, so Bob must be the second youngest.
  • Spin refers to the Davenport Bionic Academy as "home" (Left Behind).
  • Although he and Bob are close he enjoys seeing Bob in pain (Mission Mania).
  • He was promoted back to green according to Donald saying that every student gets promoted one color up in Space Elevator.
  • He once tried to trick Janelle into thinking he was hurt by one of Leo's laser spheres to get her trapped into what he calls "The Spin Cycle" (Adam Steps Up).
  • Leo never believed that he could actually spin, he only thought he could twirl. (First Day of Bionic Academy).
