Tricky Van Baalen
Tricky Van Baalen was the youngest of the Van Baalen brothers.
He worked for his brothers, finding and processing salvaged spaceships. Although made captain by their father, he suffered an accident, in which he lost his eyes, his voice, and memory. He was later fitted with synthetic eyes and a partially electronic-sounding voice box, unable to replace his memory, his brothers instead convinced him that he was in fact an android.
When the brothers discovered the The Doctor's TARDIS in their ship's orbit, all three boarded it under the belief that the Eleventh Doctor was describing it as "a salvage of a lifetime", but who had trapped them inside in a desperate attempt to find Clara. Whilst inside the TARDIS his brother Gregor confessed that he was Human, when he became trapped by a metal beam, and his brother refused to cut through his arm. He was also chased by a future "zombie" version of himself, but their discovery of the TARDIS was negated when the Doctor altered their timeline.
When the timeline reverted however, a photograph of the three brothers and their father remained intact (it had previously been torn to omit Tricky as part of his brothers' ruse), and Gregor treated him with more respect. (TV: Journey to the Centre of the TARDIS)
