Olympian

Olympians (also referred to as Gods) were a race of tall humanoids from the planet Olympus.

Biology
Olympians were taller than an average humanoid in size and their physiology was the same as that of humans. (COMIC: The Life Bringer!)

Abilities
Olympians could never die of old age. They were shown to be invulnerable to photon beams, for example, when K9 Mark II used them against two Olympians, who were unaffected. They were also able to survive in the vacuum of space without the need of oxygen.

Olympians were able to summon different types of energies when needed. Prometheus was able to use an electric wave on the TARDIS which made it travel to Olympus. Zeus was able to appear in a gigantic form amongst clouds and emit massive amounts of electricity at the TARDIS. However the ship was unharmed by his attack. (COMIC: The Life Bringer!)

Culture
All Olympians obeyed the will of their leader Zeus; however, some were known to go rogue. Their attire appeared to be the same, which was a white toga. (COMIC: The Life Bringer!)

Technology
Olympian technology was very advanced. Known transportation included shell-crafts, which could travel through the atmosphere, as well as metal chariots. (COMIC: The Life Bringer!)

History
The Olympians were responsible for controlling some parts of the universe. The Olympian Prometheus was responsible for creating life in the universe. (COMIC: The Life Bringer!)

By another account, which did not mention the name of their race, Zeus and several of his people travelled the universe in a spaceship; they first arrived on Earth after capturing the alien criminal Medusa, who hijacked their ship and crash-landed it in ancient Greece. (COMIC: Gaze of the Medusa)
