Hex

Hex was a short lived companion of Seventh Doctor and Ace, before staying on Gallifrey at the Time Academy. Right before the Time War, Hex left Gallifrey in search of the Doctor. He was eventually found by the Doctor in his Tenth incarnation with the young Matty James. Together, they now travel together in the TARDIS.

Biography
Hex was born on October 12, 1998 to a woman name Cassandra (Cassie) Scofield, his father apparently unknown. In his infancy he as handed into his maternal grandmother’s care though this did not seem to be of Cassandra’s own volition. Hex remembers little of his childhood, but there are reasons for this. Unbeknownst to Hex his mother had become the victim of a mysterious organization called the Forge and had been transformed into a vampire. The Doctor in his Sixth incarnation promised to try and cure her, but she fell in with the Forge and lost her life. The Doctor knows Hex is her son, but he does not know that Hex himself has been under influence of the Forge.

Hex first met the Doctor and Ace when they were investigating signs of alien activity at St. Gart's. When Hex witnessed her going into a police box and demanded to know what was going on, Ace let him inside the TARDIS, shocking him outside of his limits. He assisted the Doctor and Ace in their investigation of 'xeno-tech' some alien technology, which was in fact Cyber Technology which had been reversed engineered. After aiding the Doctor and Ace, Ace managed to convince the Doctor that Hex should join them on their travels.

Hex and Ace eventually ended up on Gallifrey at the Time Academy, but the events leading up to the Time War caused Hex to flee the planet in a stolen TARDIS, after a series of events he crash landed on the Carrionite home world when the Eye of Harmony was cut off along with the entire Time War. Hex was rescued by the Doctor in his Tenth incarnation and resumed traveling with him and the Doctor’s new companion Matt James.

Secret Origin
His mother had been separated him (as it turned out Nimrod had been responsible for separation of mother and son) Nimrod tried to influence Cassandra by threatening her son, but with the help of Evelyn Smythe had broken free, and Nimrod killed her. Nimrod frustrated by the events at the Forge sought to destroy the Doctor through Hex, but was surprised to learn that Hex had traits in common with the Doctor (but only one heart.). Nimrod infected him with nannites designed to hide any trace of his Gallifreyan heritage. He then tried to keep track of the Doctor’s movements but found it impossible to do due both to the Doctor being a time traveler and generally erratic by nature, but the Doctor and Hex still managed to meet up. The Doctor did not know of Hex’s heritage, and could not sense it because of the nannites. When Hex went to Gallifrey to study, he was still not know to be half Gallifreyan, however when he was forced to flee in Omnia’s TARDIS, the long dormant TARDIS recognized him immediately as a Time Lord and imprinted on him. Whatever programming the nannites might have are unclear since Nimrod has never had the chance to remove them.

Personality
Hex’s most dominate trait is his innate kindness, matched only by his playful wit most often seen in quips used to deflate the Doctor’s ego. He can seem to be quite mischievous except that he rarely ever gets into mischief, but can often seem like he had been up to just that. He has a natural tendency to go out of his way to help people. Because Hex is unaware of his full background, or truthfully any of his origin, he tends to down play his intelligence, but seems to accept most situations no matter how strange they might be.
