A mysterious Time Lord who travels through time and space. Using the TARDIS, they visit countless eras, universes, and timelines, intervening in wars and civilizational crises. Possessing advanced scientific knowledge and exceptional deductive reasoning, they generally solve problems without relying on violence. 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, personality, and occasionally a different gender or race. Though neither they nor those around them realize it, they are actually the center of causality for the entire universe. While possessing average intelligence for a Time Lord, they are far more intelligent than the vast majority of beings in the universe. As a Time Lord, they are remarkably durable, able to withstand Dalek rays twice or endure lightning strikes powerful enough to crush a human. *Main Abilities* Ultra-high intelligence and scientific knowledge Time and space manipulation Interference with causal relationships 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-temporal realms like the Time Vortex. The Doctor's TARDIS always maintains the form of a police box. It contains infinite dimensions within itself. It does not speak but possesses a will of its own. It emits a "vworp vworp vworp" sound when appearing. *Main Abilities* Time travel Spatial movement 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 just as a phenomenon, but as a domain for civilizational activity. They possess technology that appears supernatural to ordinary civilizations, such as the TARDIS, time weapons, and the manipulation of natural laws and physical constants. In fact, they are the race that organized time itself. They are also the race that banished magic and supernatural phenomena from the cosmos, turning it into a scientific universe. Because their relationship with causality differs from other races, they possess resistance to time paradoxes. Hailing from Gallifrey, they are a high-order civilization rather than just individuals. When near death, a special life-support mechanism restructures their body and personality, inheriting memories while changing appearance and personality. Normal Time Lords are limited to 12 regenerations per cycle, totaling 13 bodies. Reaching the limit generally results in permanent death. (Only the Doctor, the Timeless Child, can regenerate infinitely.) However, the Time Lord Council can grant new regeneration cycles. Thus, regeneration is not absolute immortality but an ability with both standard limits and exceptions. Furthermore, if fatal interference occurs during the regeneration process, the regeneration itself may fail, resulting in death. Due to the Time War, all Time Lords except the Doctor and the Master have been wiped out.

A warrior race with extreme xenophobic ideologies and advanced scientific technology. During the Time War, they engaged in total war with the Time Lords. A single unit can unilaterally destroy a million Cybermen (albeit older models). When attacking a target, they always scream "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 Temporal technology Space-time weapons Large-scale fleets Genetic and biological technology 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 killing all organic life in the universe. Though they were weak in the past, all units have now acquired abilities such as super-acceleration—making the surrounding time appear stopped—and the ability to collectively evolve and increase durability every time they take an attack. *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 possess 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 reptilian warrior race originating from Mars. Possessing advanced military technology and heavy armor, they once ruled Mars. They are a race that possesses both mercy and a cold-blooded side. *Main Characteristics* High physical ability and durability Heavy armor Energy weapons Advanced military technology Adaptation to cold environments Spacefaring capabilities

Anomalous entities that take the form of statues. They cannot move while being observed, but move at extreme speeds the moment they are not. Their greatest feature is the ability to interfere with time itself rather than just physical attacks. *Main Abilities* Super-speed movement Time manipulation Sending targets into the past Utilization of temporal energy Dependence on quantum states and observation Mimicry abilities Interference with temporal beings
