Kroton (Throwback: The Soul of a Cyberman)

Kroton was a Cyberman who uncharacteristically retained his emotional capacity. He travelled with the Eighth Doctor and Izzy.

Biography


Little is known about Kroton's original life. He had a family and a wife before he was taken from them. He himself would forget all of his past. (DWM: Unnatural Born Killers, The Glorious Dead)

Kroton was a junior Cyber-Leader, among those sent from Telos to assist in the invasion and management of the planet Mondaran.

He began to question his superiors and fight back as he discovered his emotions. He helped a group of Mondarains to escape their planet and Cyberman rule. The ship they used to escape was low on fuel. Rather than maroon himself to die on a jungle planet, he set off into space to drift alone and deactivated himself. (DWM: Throwback: The Soul of a Cyberman)

A cruise spaceship, the Flying Dutchman II, which was stuck in a lateral stasis field, found Kroton's ship and the human passengers reactivated him. He helped remove it from the stasis loop, but discovered the ship had been trapped for six hundred twenty-eight years. The mortal passengers all rapidly aged and died, leaving Kroton on his own again, with only the ship's robot pilot for company. (DWM: Ship of Fools)

After that Kroton travelled through space. He prevented an act of genocide by the Sontarans. (DWM: Unnatural Born Killers) Kroton encountered the the Eighth Doctor and his companion Izzy on the Qutrusian Cargo Freighter X-703. After assisting them, he joined them in the TARDIS. (DWM: The Company of Thieves)

Kroton left the Doctor after a battle with the Master during the Master's pursuit to become the centre of the omniversal spectrum. He reached Pandarost, the planet where the Master had prepared his trap for the Doctor and Izzy. Both were caught in the Church of the Glorious Dead's assault and barely survived, living a hard existence for nearly a month, fending off attacks by cultists and their monstrous Ash Wraith forms. Kroton finally did battle with Sato Katsura, lasting against him much longer than any other foe due to his enhanced physiology. Before long, however, Sato was sent reeling from the fight when Izzy forced upon him a mnemonic crystal and fed him back all the pain she had suffered at the hands of the Church. She gave the same crystal to Kroton, who used it, though he had rejected it before. It awoke memories from before his Cyber-conversion. He remembered all the happiness and sorrow he had ever felt as a human being. He accepted them and chose joy over misery. He was chosen as the new centre of the Omniversal Spectrum, banishing the Master and restoring the history he had warped, granting Sato his ultimate wish for honourable death as he left for the heavens. (DWM: The Glorious Dead)

Iris Wildthyme, who had a history of claiming that the Doctor's adventures were her own, mentioned that Kroton travelled with her for a time. (EDA: The Scarlet Empress)

Personality
Kroton appreciated beauty. This made the Doctor realise Kroton was no ordinary Cyberman. He also withstood the impression of the interior of the TARDIS; when the Doctor asked him if it struck him as "illogical", Kroton happily cast away the word, stating "screw logic!". (DWM: The Company of Thieves)

He had a balanced sense of right and wrong, becoming utterly infuriated at the possibility of a Sontaran plan for genocide of innocent natives and the Church of the Glorious Dead's atrocities against the alien ambassadors on the planet Paradost. (DWM: Unnatural Born Killers) Before he touched the mnemonic crystal offered to him by Izzy Sinclair, he suffered from flashbacks of his former life. These saddened him as he could not access all his memories and he felt the pain those memories would bring would be greater than the joy, making him reject the crystal initially. However, upon embracing those memories and his humanity, he became a complete person again and left to have his own adventures soon after. (DWM: The Glorious Dead)
