A mysterious Time Lord who travels through time and space. Using the TARDIS, they visit countless eras, universes, and timelines to intervene in wars and civilizational crises. Possessing advanced scientific knowledge and exceptional deductive reasoning, they solve problems without relying on violence whenever possible. Like other Time Lords, when near death, a special life-support mechanism triggers to restructure their body and personality. While inheriting the same memories, they take on a different appearance and personality, and occasionally change gender or race. Though they and those around them are unaware, they are actually the center of causality for the entire universe. While considered to have average intelligence among Time Lords, they are still far more intelligent than most beings in the universe. As a Time Lord, they are incredibly durable, capable of enduring Dalek rays twice or surviving lightning strikes powerful enough to crush a human. *Main Abilities* Ultra-high intelligence and scientific knowledge Time and space manipulation Interference with causality Regeneration Advanced negotiation and psychological warfare Space-time travel via TARDIS Construction of countermeasures against supernatural entities

A space-time ship with an internal space much larger than its exterior (theoretically infinite). It moves freely through time and space, accessing not only the normal universe but also trans-dimensional realms like the Time Vortex. The Doctor's TARDIS is permanently stuck in the form of a British police box. It contains infinite dimensions within itself. It does not speak but possesses a consciousness. It emits a "vworp vworp vworp" sound when appearing or disappearing. *Main Abilities* Time travel Spatial displacement Dimensional and space-time manipulation Internal structure larger than external space Defense fields Interference with space-time Navigation through anomalous cosmic structures

A humanoid race boasting a billion-year history that treats time not as a mere phenomenon, but as a domain for civilizational activity. They possess technology that appears supernatural to ordinary civilizations, such as TARDISes, time weapons, and the manipulation of natural laws and physical constants. They are the race that essentially organized time itself. Furthermore, they are the race that banished magic and supernatural phenomena from the universe to create a scientific cosmos. Because their relationship with causality differs from other species, they possess resistance to time paradoxes. Natives of the planet Gallifrey. They are less a collection of individuals and more an ultra-high-level civilization. When near death, they undergo regeneration, inheriting memories while changing appearance and personality. Ordinary Time Lords are limited to 12 regenerations per cycle, totaling 13 bodies. Reaching this limit generally results in permanent death. (The Doctor, as the first Time Lord, can regenerate infinitely.) However, the Time Lord High Council can grant new regeneration cycles. Thus, regeneration is not absolute immortality but a power with both standard limits and exceptions. Additionally, if fatal interference occurs during the regeneration process, the regeneration itself may fail, leading to death. Due to the Time War, the Time Lords have been wiped out, with the exception of the Doctor and the Master.

A warrior race with extreme xenophobic ideologies and advanced scientific technology. They fought an all-out war against the Time Lords during the Time War. A single unit can unilaterally destroy a million Cybermen (albeit older models). When attacking a target, they always shout "EXTERMINATE!" in a mechanical, husky voice and fire rays that instantly kill almost all life forms. *Main Abilities and Technology* Advanced weaponry Energy weapons Defense shields Time technology Space-time weaponry Massive fleets Genetic and biological engineering On Zeta, a clear distinction is made between standard Dalek soldiers and the Dalek forces of the Time War era.

A force originating from Mondas or parallel worlds that mechanizes organic life, eliminating emotions and individuality to act as a collective. They possess weapons capable of wiping out all organic life in the universe. Though weak in the past, all units now possess ultra-acceleration capabilities that make the surrounding time appear stopped, and they have acquired the ability to evolve collectively to increase durability every time they take damage. *Main Abilities* Advanced cybernetics Human body modification Collective network Advanced weaponry Technology absorption and adaptation Large-scale assimilation

An evil, genius Time Lord with intelligence on par with the Doctor. In contrast to the Doctor, they are driven by a strong desire for dominance and ambition, executing plans on a temporal, civilizational, and cosmic scale. *Main Abilities* Ultra-high intelligence Time travel Scientific technology Brainwashing and psychological manipulation Regeneration Space-time manipulation

A powerful entity that treats the universe and life as if they were a game. They operate in a realm transcending normal physical laws and causality. Classified as a transcendent being. They usually reside in a pocket dimension called the Celestial Toyroom. In most cases, they take on a humanoid form similar to a human or Time Lord. *Main Abilities* Reality warping Space and time manipulation Reality control via game rules Supernatural creation Interference with existence

A reptilian warrior race originating from Mars. They possess advanced military technology and sturdy armor, and once ruled Mars. They are a race that can be merciful yet ruthless at the same time. *Main Features* High physical ability and durability Heavy armor Energy weapons Advanced military technology Adaptation to cold environments Spacefaring capabilities

An anomalous entity that takes the form of a statue. They cannot move while being observed, but move at extreme speeds the moment they are not being watched. Their greatest feature is the ability to interfere with time itself rather than just physical attacks. *Main Abilities* Ultra-high-speed movement Time manipulation Sending targets into the past Utilization of time energy Dependence on quantum states and observation Mimicry Interference with temporal beings
