Doctor Who: The Fifteenth Doctor: The Prison Paradox

The Doctor Who: The Fifteenth Doctor: The Prison Paradox continues with the Doctor's adventures through time and space alongside a team of allies from across the universe. These companions are fellow prisoners held captive in a maximum security space prison! Each ally has a story to tell and a role to play in uncovering the mysteries of their incarceration.

Annie the Adipose: The Adipose are a parasitic race, only able to reproduce through the death of others. When discovered, they are euthanised or imprisoned to prevent interplanetary epidemics.
Conviction: Existence as a parasitic lifeform.

H-8 the Cyborg: A ship of Theseus comprised of pilfered cybernetics, H-8 doesn’t remember what part of him is biological anymore, or what species he started out as. A hulking being obsessed with firepower, he’s bristling with weapons— including a Dalek gun attached to his arm! Despite this, he’s surprisingly affable. You’d like him.
Conviction: Weapons theft.

Felik the Slitheen: Embarrassed by her family’s history, Felik fled them to become the pirate scourge of two galaxies. She is endlessly hunted by her own kind.
Conviction: Piracy.

Meezan the Tentaculon: An aquatic squid being made entirely out of twisting tentacles, Meezan is the last of her kind and is very sad about it. After her underwater planet became a desert, she returned to try and flood it. This was not taken well by the land-dwelling species that had come to settle there.
Conviction: Attempted terraforming without a permit.
