The Beast

The Beast's powers and abilities

The Beast could manifest itself through electronic media, including computer voices and hologram viewers. Its mind could leave its body and possess a single hive mind of the Ood collectively and/or a single human individually. It had the power of telepathy and, through a host, telekinesis. Possession of a human subject affected the host's skin, causing strange markings to appear all over their face and body; and vocal cords, allowing them to speak at different pitches simultaneously. Whether a single human or a hive mind, the eyes of those possessed by the Beast glowed a fiery red. The Beast could also project fire from his mouth, as could its possessed hosts. Its hosts could also physically survive in a vacuum. The Beast's existence seeped into the subconscious of all sentient beings across the universe, becoming the basis of the Devil-figure in all religions. Although defeated by the Doctor and Rose, the Beast claimed that it could never be destroyed as the thought of it would live on.

Immortality

The Beast has lived since "before time" and had been imprisoned within Krop Tor since the beginning of the universe, never ageing. Even when possessing a human vessel, it seemed to be unaffected by hazardous environments, as demonstrated when it stood on Krop Tor's surface in hard vacuum while controlling Toby Zed. While its body and, later, its possessed vessel Toby were both consumed by the black hole, it is uncertain if this was enough to truly destroy it completely.

Telepathy

The Beast is able to communicate directly with people's minds, influencing them subtly or outright dominating them through possession. It can read the thoughts of others and uses their own fear and guilt to torment them.

Precognition

The Beast has also demonstrated the ability to see the future. When introducing itself to the Sanctuary Base crew, it read Rose Tyler's mind and saw her future, stating that she would "soon die in battle". This premonition came true, in a way, as Rose would become caught up in the Battle of Canary Wharf between the Cybermen and the Daleks when she returned to Earth in her own timeline. While Rose did not actually die during this conflict, she ended up being stranded on a parallel Earth and was officially declared dead back on her world.

Telekinesis

The Beast can manipulate objects without touching them, as demonstrated when it tore open an airlock and sucked Scooti Manista out into hard vacuum.

Pyrokinesis

Whether in its own body or a possessed vessel, the Beast has shown to be capable of breathing fire.

The Beast's weaknesses

Under specific circumstances, can be bound to a host if he possessed and thus became vulnerable to a mere black hole, although this is unlikely to come up in combat.
