The Prison Paradox

H-8 THE CYBORG: A ship of Theseus 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.

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 very sad about it.

After her underwater planet became a desert, she returned to try and flood it.

Which was not taken well by the land-dwelling species that had come to settle there.

Conviction: Attempted terraforming without a permit.
