Victor Krane is the mysterious person who used to help Douglas Davenport and has bionic powers. He wears a mask in No Going Back and Sink or Swim; however his identity was revealed in the episode Sink or Swim. He was the main antagonist of Season 3, since he started the Bionic War. He still casts his influence in Season 4.
After Douglas was booted out of Davenport Industries, he found Krane, a billionaire who agreed to fund his works, only if Douglas Davenport were to share his work with him. Victor Krane then went on to implant himself with bionics that Douglas created. In addition, he also used Douglas' tech and knowledge to genetically engineer Bionic Soldiers behind his back. He broke Douglas Davenport out of prison (as masked man) ,which revealed a bionic ability that he had in the episode, No Going Back. His identity was revealed in the episode Sink or Swim. Another ability that was revealed in Sink or Swim was lightning fingers. He is somewhat of a tempered person and "all around bad-guy" as Douglas says. The reason that he wears the mask is because of the wires that are on his face due to his bionics. At the end of Sink or Swim, he ordered Douglas to kill Adam, Bree and Chase. He is part of an ongoing conflict with the team. In Taken, Krane continues to implant himself with more bionics and tried to kill Douglas He was trying to kill Adam, Bree, and Chase and he was about ready to do when Douglas came in with a secret weapon. When Douglas is about to kill Krane, he geo-leaped away, before Douglas had the chance to fire.
Krane later made his next appearance in You Posted What?!?. He had a new bionic soldier "keeping tabs" on the Lab Rats, which was how he was able to find Douglas and Leo at school. His new bionic soldier and partner, S-1, came in soon afterwards. She was revealed to have had Douglas's triton app upgraded on her, meaning Krane could control her abilities from his brain. He refused to reveal his plan and electrocuted Douglas and Perry. He then ordered S-1 to take care of Leo, or in other words, kill. After S-1 "took care" of Leo, they both left to carry on with their plan.
They soon returned to the warehouse, where they found out Leo had his crushed arm healed and upgraded with bionic powers. Nonetheless, S-1 and Krane didn't let them (along with the other Davenports) go. They had a brief showdown, and just as Krane was about to let it loose on Adam and Chase, Leo stopped him with a fireball to the head, knocking him out temporarily. When he heard he would be taken into custody with S-1 by Special Agent Graham and his soldiers, he screamed, "I don't think so!" and launched a stream of fire at him. Bree saved him while Adam lasered his bottom, knocking him out again. He and S-1 were placed in a bionic-proof cell, but, thanks to a mysterious ability, he called to his bionic army, "Rise, bionic soldiers! RISE!".
Krane is mentioned in Merry Glitchmas when Donald mentions him as a "Bionic Madman."
Krane appears again in Rise of the Secret Soldiers. He uses a bionic army to take over mankind by signaling the Triton App to the whole planet while using government satellites. He is then defeated by Adam, Bree, and Chase, while getting blasted far away. It is unknown if he survived or not. It is possible that he might have been blasted into space.
However, this was not the last of Krane, as his legacy would still have an effect on the Lab Rats. After Douglas turned on him, Krane remotely reprogrammed his pet dog Otis as a contingency plan. Krane gave Otis the mission to find Douglas and destroy him as punishment. Even after Krane was defeated, Otis wouldn't stop until his mission was complete.
Also, Chase, who became a mentor of the world's first Davenport Bionic Academy, inadvertently told Sebastian, one of his students, about what happened with Krane. This proved to be fatal mistake, however, because Sebastian secretly swore to avenge his creator's defeat and carry on his legacy.
