Main characters

 * The Doctor (played and voiced by Tom Baker) - A Time Lord from the planet Gallifrey in the constellation of Kasterborous, he travels in time and space with companions in a time machine disguised as a blue British police box known as the TARDIS (Time and Relative Dimensions in Space). He is known throughout his respective universe as a hero who has stopped villains, defeated monsters and saved countless civilisations. He also has the ability to regenerate when injured or dying by changing into a new body. By the time he meets Dipper Pines and Kung Lao, The Doctor is in his fourth incarnation and is travelling with companions Romana and his robot dog K9. He acts as a wise mentor to Dipper and Mabel Pines, and learns many new fighting styles from Kung Lao and his companion Sub-Zero. He faces a life-threatening challenge when his arch enemy, The Master, regenerates into a more powerful incarnation, who, with the aid of the Daleks and Cybermen, begins the First Great Time War, and separates The Doctor from his friends to go against him in a battle that takes them across the entire planet of Gallifrey.
 * Kung Lao (played and voiced by Wil Yun Lee) - A martial artist and fighting champion renowned throughout the Earthrealm in his universe, he is a former member of the White Lotus Martial Arts Society and one of the descendants of the Great Kung Lao, a Champion of Mortal Kombat. He is a renowned fighter throughout his homeland of the Earthrealm and is fluent in several fighting styles including Mantis, Shaolin Fist, Kenpo and Wing Chun. Being a warrior, he is primarily armed with a Razor-Brimmed Hat, a Battle Axe and a Broadsword. He has fought against his arch enemy Shao Kahn many times, and does not think twice before deciding to confront him once again. He is travelling with fellow Mortal Kombat fighter Sub-Zero when he is thrust into the adventure with The Doctor, Dipper Pines and the rest of the group. He proves himself to be a strong and wise leader when he leads the group across the EarthRealm and NetherRealm to make it to the Outworld to battle the evil Shao Kahn and his accomplices.
 * Dipper Pines (played and voiced by Jason Ritter) - A tourist trap employee at the Mystery Shack in Gravity Falls, Oregon, he is the twin brother of Mabel Pines and a junior explorer who is always raring for a new adventure. He is renowned throughout Gravity Falls, considered to be wise beyond his years and cannot wait to grow up to be a man. He is armed with the legendary 'Journal 3' which has become a true lifeline for his adventures. Dipper and his sister are staying with their Uncle Ford for the summer holidays during the events of the first series, before joining The Doctor, Kung Lao and the rest of the group in the fight to separate the collided universes. He shares a great friendship with the Doctor's robot dog K9, and looks up to Romana and Sub-Zero as role models. When the Weirdmageddon event happens for a second time, Dipper and his sister don't hesitate to help their new friends combat the dreaded Bill Cipher once again.
 * Bill Cipher (voiced by Alex Hirsch) - A powerful, interdimensional dream demon that can be summoned and released into somebody's mind, and the arch enemy of Dipper Pines. He resembles a one-eyed, yellow triangle with a top hat and a bow tie, superficially similar to the Eye of Providence. He can read people's minds and memories, shift forms, warp reality, maintain cross-dimensional awareness, possess bodies, encrypt and decrypt codes, and shoot laser energy blasts from his eye and fingers. Throughout their battles, Cipher has tricked Dipper countless times and Pines has vowed to get rid of him eventually. Cipher's alliance with The Master and Shao Kahn is discovered to be a foretold legend hidden for a trillion years throughout Cipher's existence and plans to get his own way from the deal and eliminate all of the Pines in Gravity Falls. He attempts to convince Kung Lao, The Doctor and the rest of the group to share in his power as his accomplices, but Dipper and his sister Mabel help them resist his mind games and the heroes finally join together to defeat him in a combined effort.
 * Shao Kahn (played and voiced by Frank Welker) - A brutal warlord and the emperor of the mystical Outworld realm, he is feared by many for his godlike strength and knowledge of black magic, and he seeks to conquer all of the realms of the Mortal Kombat universe and merge them with Outworld. He was at first an advisor to the emperor of Outworld, but later poisoned him and took control of the realm and the armies belonging to the emperor. A terrifying figure, he is armed with a War Hammer primarily, but also carries a Spear and a Staff. He has a long and bloody history with Kung Lao and the rest of the Mortal Kombat fighters, and will not stop at nothing to see them and all who oppose him eliminated. He shares a significant factor of hatred in his personality with The Master, but simply sees Bill Cipher as a power-crazed, psychotic demon, however he is willing to work with him only to achieve his own goals.
 * The Master (played and voiced by John Simm and Michelle Gomez) - A renegade Time Lord from the planet Gallifrey, he is the same species as his arch enemy, The Doctor, and has the ability to regenerate when his body is either damaged or dying. His ambition is to control the universe, and eliminate the Human race on the planet Earth to make The Doctor suffer. During the series, The Master's incarnation is known as the 'Harold Saxon' incarnation, however he later regenerates into a female known as 'Missy'. Between the events of The Mondasian Colony and his latest regeneration, he travels back in time to attempt to kill the Time Lord Rassilon who had orchestrated his entire life as a puppet of the Time Lords. However, he cannot do this when his universe collides with that of Shao Kahn and Bill Cipher, and must make an alliance with them. He regenerates into Missy after the First Great Time War begins. The Doctor's memory of Missy is wiped soon after the end of these events.
 * Romana (played and voiced by Lalla Ward) - A Time Lady from the planet Gallifrey, she is the same species as her best friend, The Doctor, and like all Time Ladies, she has the ability to regenerate when her body is damaged or dying. She is extremely intelligent, having graduated from the Time Lord Academy with a triple first, and occasionally outsmarts The Doctor. She first joined The Doctor and their robot dog K9 during the events of The Key to Time, and her bossy, prideful and dismissive attitude did not mix very well in the TARDIS. Soon after however, she regenerated into a likeness of Princess Astra of Atrios, and her personality suddenly became more laid-back, relaxed and humorous. She is still in this incarnation when she meets Dipper Pines and Kung Lao. She develops a friendship with Dipper's sister Mabel, and fiercely protects the young girl during the battle against Shao Kahn. She soon begins to develop romantic feelings for The Doctor, and seeks advice from Mabel and Kung Lao, but she doesn't reveal those feelings for him.
 * Mabel Pines (played and voiced by Kristen Schaal) - A tourist trap employee at the Mystery Shack, she is the twin sister of Dipper Pines. She is an eccentric, buoyant, and energetic optimist, who expresses herself through an assortment of colorful knitted sweaters, as well as her skills in various arts and crafts. Her outgoing, curious personality often helps Dipper solve mysteries, though her silliness is often seen as a burden. Mabel enjoys preteen novels and seeks romance (especially in vampires). Despite what she sees as dating obscurity in Gravity Falls, Mabel stays optimistic. She won a pig she named Waddles at a summer fair, and ever since then the two have been inseparable. Mabel is frequently instrumental in helping her brother solve the mysteries of Gravity Falls and has played a pivotal role in all four of the fights that the twins have had against the main antagonist, Bill Cipher. When she and Dipper join The Doctor, Kung Lao and the rest of the heroes at the end of the first series, she develops a heartwarming friendship with The Doctor's friend Romana.
 * Sub-Zero (played and voiced by John Tobias) - A fighting champion and martial artist from the EarthRealm, he is a Grandmaster warrior of the Lin Kuei assassin Clan who possesses the innate ability to control ice in many forms. Two warrior brothers took the identity of Sub-Zero, Bi-Han, the elder of the two, and Kuai Liang. Sub Zero shares a bitter rivalry with the undead specter Scorpion due to Bi-Han killing him prior to his resurrection, and Kuai Lang later attempting to avenge Bi-Han's death at Scorpion's hands. In contrast with his older brother's more anti-heroic and later villainous personality, the second Sub-Zero typically adapts a heroic persona as one of the fighters helping defend Earthrealm against various threats. He is fluent in fighting styles Shotokan and Dragon, and can transform ice into abilities such as Ice Blast, Ground Ice, Ice Clone and Ice Shower. He is training with fellow Mortal Kombat fighter Kung Lao when he is thrust into the adventures with The Doctor and Dipper Pines.
 * K9 (voiced by John Leeson) - A mobile computer robot dog created in the year 5000 by Professor Marius, he is a companion of The Doctor and Romana during the events of the series. He was originally created when Marius could not take his own Earth dog into space with him, so he constructed K9. However, when Marius could not take him back to Earth, K9 decides to join The Doctor and his then-companion Leela, and he remains with them until the events of the Sontaran Invasion on Gallifrey, when Leela decides to leave The Doctor. However, he soon replaces K9 with a new model after the original's departure, and he travels with The Doctor and Romana. He has many abilities such as firing a laser beam set to stun or kill, rotating ear-probes and a wagging tail antennae. He addresses whoever is directing him as "Master" or "Mistress" depending upon gender, and uses the formal "affirmative" and "negative" rather than "yes" and "no". When he, The Doctor and Romana join the heroes in the series, he normally remains with Romana and Mabel Pines if The Doctor is occupied.
