Prometheus (The Life Bringer!)

Prometheus (also known as Prometheus the Life Bringer) was an Olympian who created life in the universe.

Creation of life
Prometheus sought to which he referred to as beautifying the universe with living creatures. By doing this he stole from the temple on the planet of Olympus some life spores which he unleashed across the universe. This however angered Zeus who banished him to be chained to a mountain on an unamed planet for the rest of his exsistence. (DWM: The Life Bringer)

Freedom
Over time, the mountain which Prometheus was chained to had eroded to a small rock.

Eventually the Fourth Doctor and K9 Mark II arrived to the unknown planet and came across Prometheus eventually freeing him from his chains with K9 using his photon beams to break them. Once freed Prometheus used his powers to send the TARDIS with the Doctor and K9 to the planet Olympus but once there they were confronted by Aphrodite who took them to the huge temple where they were to be judged by Zeus.

Prometheus was put into a confinement room which he thought to escape by pounding on the wall for a thousand years. However the Doctor eventually escaped along with K9 and let him out. Prometheus quickly collected some more life spores which he would once again spread new life across the universe in act of revenge against Zeus.

He, the Doctor and K9 eventually was able to quickly leave via the TARDIS before Zeus could harm them. Once in space Prometheus exited the TARDIS and headed to an unknown planet which the Doctor speculated it could be the Earth but wasn't sure. (DWM: The Life Bringer)
