The Doctor

A 2,000+ year old time traveler from the planet Gallifrey. As a Time Lord, he is capable of regenerating into a new body if he’s mortally wounded. The Doctor travels through time and space in his ship called the TARDIS, fighting monsters, saving worlds, and being rather sort of marvelous.

Regeneration
The regeneration cycle of the Storyteller Doctor began as an alternate version of the War Doctor (played by John Hurt in the official Doctor Who series). Unlike the official timeline, this incarnation did not eschew the title of "Doctor," and took action to end the Last Great Time War sooner in his lifetime than his counterpart. This makes the "Red Scarf Doctor" the 9th Doctor in this timeline.

After using The Moment to seemingly destroy Gallifrey and the Daleks together, the Doctor aimlessly drifted alone through time and space. One day, the TARDIS brought him to a world called Opex 7. There, the Doctor was captured by a man who had once been the servant of an entity known as the Trickster, but had been cast off by it. The Servant had had his life saved by the Trickster, who, in return, demanded that he lower the planetary shields of Opex 7 and allow it to be destroyed by a randomly passing asteroid. The Servant had refused, breaking the agreement with the Trickster and causing his mind to be broken in retaliation. The Servant knew of the Doctor, and hoped that capturing him and handing him over to the Trickster would redeem himself and free him of the mental agony he was under.

The Doctor convinced the Servant to go with him in the TARDIS back to the moment when the asteroid was to hit the planet, allowing the Servant another chance to fulfill his contract. Confused, the Servant demanded to know why the Doctor was doing this. The Doctor replied that he wanted the Servant to prove to himself that he was strong enough to endure his torment in exchange for the peace of knowing that he was a good man. Unfortunately, the plan backfired. Overwhelmed by the pain, the Servant deactivated the shields, allowing the asteroid to come. Dejected, the Doctor began to leave, but the Servant shot him, mortally wounding him. The Doctor made it back to the TARDIS just before the asteroid hit, and watched as Opex 7 was destroyed. He vowed to never forget his failure to help the "tiny little man on the unknown planet" and regenerated into the man's likeness.

First Encounter with the Storyteller's World
This incarnation of the Doctor first appeared in the Storyteller's universe when he and his faithful companion materialized near Uncle Bob's front yard while the latter was mowing his lawn. The Doctor thought they had landed on New Earth in the far distant future, but after mistaking Uncle Bob for a hideous alien, realized he had miscalculated their destination. The Doctor gave Uncle Bob some Jelly Babies (though they ended up being stale Gummy Bears), and offered to fix his lawn mower. He quickly repaired it with his sonic screwdriver, and volunteered to do a couple passes of mowing. Uncle Bob promptly went back inside and let the Doctor finish mowing his lawn.

Meeting the Storyteller
Some time later, the Doctor, searching for a new traveling companion, materialized the TARDIS in the Storyteller's studio in the middle of a movie review. He offered the Storyteller a chance to travel with him, but the Storyteller refused the offer, saying he needed to finish his review first. The Doctor apologized for interrupting, and left.

The Doctor eventually returned, and the Storyteller joined him for a short time, traveling into his own past to review Time Changer. After the review, the Storyteller returned to the TARDIS moments before his past self entered the room.

After the Storyteller left the TARDIS, the Doctor discovered that he could observe a parallel universe, and found that universe's version of the Storyteller. He and the Storyteller watched Alter-Zack review the movie Second Glance. After the review was over, the Storyteller tried to adjust the video feed, but accidentally changed it to a view of the Void, the empty space between universes. As they watched, they were greeted by Genocron, who begged the Storyteller's help to free him from the Void.

The Doctor did not directly participate in the Battle for the Hat, though he did help some. When Uncle Bob received a death threat from his brother Uncle Billy, who was working for Genocron, the Doctor allowed him to stay in the TARDIS while Mr. Researcher used a holographic decoy to make the villains think Uncle Bob had been killed. When the Storyteller was captured by Cowhead the Pirate, the Doctor piloted the TARDIS to the moment, revealing that Uncle Bob was still alive and freeing the Storyteller before Genocron could get the hat.

Family Reunion
After Genocron was defeated, the Doctor permitted Uncle Bob to travel with him for a time. It wasn't long before the Doctor's patience for Uncle Bob's antics ran out. After one too many hijinks, the Doctor literally threw Uncle Bob out of the TARDIS. Frustrated and lonely, the Doctor longed for the happier days of traveling with family. His reverie was cut short by the arrival of a hyper-cube, a Time Lord distress beacon. The message appeared to come from his granddaughter, Susan, whom he had thought was long since killed in the Time War. Following the beacon, he found Susan stranded on a planet overrun by Daleks. He found her just as she was finishing regenerating after being attacked by a Dalek Puppet. Their joyous reunion was cut short as her new regeneration quickly failed, the damage sustained in the attack having damaged both her hearts. She regenerated two more times before the Doctor was able to take her back to the TARDIS to stabilize her.

After narrowly escaping a squad of Dalek Puppets, the Doctor managed to get his granddaughter back to the ship, and used the TARDIS' zero-room to finally stabilize her. Restored, the Doctor and Susan happily set off for more adventures.

Revelations
When the Storyteller reviewed a movie starring actress Stacey Bradshaw, the Doctor noticed the resemblance between the actress and Susan. When he asked her if she had been acting in movies on Earth, she denied it, noting that the Doctor shared his likeness with the Storyteller. The Doctor hadn't realized the resemblance before, and realized that the other friends of the Storyteller, such as the Ketchup Master and Uncle Bob, also shared the same face. He confronted the Storyteller about this, and it was revealed that they were all characters brought to life from the Storyteller's imagination. Outraged that the Storyteller had withheld this information, the Doctor severed ties with the Storyteller and left.

During the final battle with the returned Genocron inside the Storyteller's mind, the Doctor appeared with the Storyteller's other characters to join forces and return Genocron to his rightful place. The Doctor, Genocron, and the others were all returned by The Potential to where they belonged in the Storyteller's mind to have their further adventures.

Travels to Other Dimensions
Resuming their travels together, the Doctor and Susan found a rift between their dimension and another. Investigating, the Doctor discovered that the timeline of the other universe was being overwritten by some kind of sinister entity, but he was unable to determine the source. Against Susan's wishes, the Doctor snuck into a central archive in a temple on one of the planets to investigate. He was discovered by one of the warrior monks that guarded the the archive. While attempting to talk his way out of trouble, the Doctor's voice began to falter and his accent changed without his control. Realizing he had probably been in the other universe for too long, and that it was having an adverse effect on him, he quickly escaped back to the TARDIS and returned to his proper universe.

Appearance
Along with his face, the Doctor's wardrobe also undergoes periodic changes. In his 9th incarnation, the Doctor wore a tan jacket and red plaid scarf over a white button-up shirt and black trousers and boots. In his 10th incarnation, he wore a dark purple jacket over a purple shirt, with black trousers and tennis shoes. He would alternate between a bright green tie and a purple tie with pink stripes. After Alter-Zack returned to his universe, leaving his plaid trilby behind, the Storyteller gave the hat to the Doctor, since he wasn't sure if it could regenerate like his own hat. The Doctor wore the hat when he rescued Susan, but decided it didn't suit him and returned it to the Storyteller later on. After returning to his universe after the final battle with Genocron, the Doctor revamped his look, wearing an long sleeved orange t-shirt, khaki pants that he wore cuffed to reveal blue plaid lining, black minimalist shoes, black suspenders, and a grey trenchcoat identical to the Storyteller's. It can't be confirmed, but it's possible the coat was another gift to the Doctor from the Storyteller to remember him by after he retired from Indy Christian Review.
