Seventh doctor

Originally a man with the demeanour Of a light hearted buffoon, The Seventh Doctor darkened into a mysterious cunning manipulator to combat Fenric's return.

Though he delighted in humorous reveri, it was only the surface of his true nature. Beneath, he was a Machiavellian and sombre genius of frightful calibre who could tactically use his mind to manipulate almost any situation into his favoured outcome. Despite this every action he did “For the greater good” as this incarnation sought out evil to vanquish. He could also show profound warmth and affection to his companions and built a strong connection with all of them.

Initially the Seventh Doctor traveled with his predecessor's final Companion Melanie Bush. After several adventures with the new Doctor, she left to go travel with Sabalom Glitz prompting him to travel with Ace McShane, a troubled teenager from Earth in the 1980s. Treating her as both a protegé and initially as a pawn in Fenric's game, he did his best to heal Ace's psychological wounds by helping her come to terms with her past misdeeds and fears, aiding her in maturing and supporting her in moments of difficulty. Although he initially planned on taking Ace home, The Doctor ended up enrolling her in the Time Lord academy on Gallifrey after being put through a test by the Time Lords.

After traveling alone for a brief time, the Doctor befriended Katie Creevy, a posh Safecracker who's father was friends with the Doctor. He and Katie then traveled together for a short while.

He finally regenerated into his next incarnation inside the tardis after his mind was consumed by time beetles

Post regeneration
To be added (TV: The brink of death)

After the laser attack, the TARDIS was caught in the Rani's tractor beam and forced to make a landing on Lekertya's surface, where the Rani and her Tetrap servant Utah boarded the TARDIS and abducted the Doctor as his Regeneration concluded, taking him to the Rani's laboratory. Awakening in her lab, the Doctor immediately recognised her but was knocked out by Urak and injected with an amnesia-inducing drug which allowed the Rani to trick him into assisting her with her project by pretending to be Mel. Upon regaining consciousness, the partially amnesiac Doctor first decided to try a new look before returning to work on the Rani's machine, having been convinced by “Mel” that he had been working on it before an accident caused him to regenerate.

However as the Doctor found out what was wrong with it, the real Mel snuck into the lab and after convincing each other of their identities, exposing the Rani's lies. Escaping, the Doctor discovered that several other geniuses from throughout time, including Albert Einstein and Hypatia had been captured to act as components of the Rani's “Time Brain”. Forced to become the final component, the Doctor's still recovering mind caused it to spout nonsense, though he also inadvertently provided the brain with the means to determine the needed substance: Loyhargil. The Lekertyan Leader Beyus then sacrificed his life to destroy the brain and delay the launch long enough for the rocket to miss the asteroid. Rescuing the captives, the Doctor took them back to their own time. (TV: Time and the Rani)

New Adventures with Mel
Travelling to Paradise Towers so Mel could enjoy its swimming pool, the Doctor found that the staff and residents residing within the Towers had all become either anarchist Kangs, cannibalistic Rezzies or pompous Caretakers. Accused of being the "Great Architect" that built the Towers, the Doctor was nearly killed by the Chief Caretaker, who wanted the Tower to run the way he wanted. The real architect, Kroagnon, a madman who killed anyone who moved into his creations to keep them perfect, was still within the complex, and had been using the Cleaners to murder residents. As the Doctor and Mel investigated, Kroagnon became concerned, and transplanted his disembodied mind into the Chief, going on a murderous rampage through the complex. He was defeated when Pex, the only remaining male resident, pushed him to his death down a lift shaft, sacrificing himself to prove his bravery. (TV: Paradise Towers)
