Dark Heresy n' Friends
Robert the Triceratops
Robert Treble was a manager at a mine in Flint, until he was kidnapped by Nez Cafe and his brain was transplanted into a triceratops body. He was given a triceratops body because Nez believed he lacked the ‘spirit’ for pit fighting, but also because Nez wanted someone intelligent to talk to.
For a while, Robert was the only Gnosis dinosaur capable of communication, first through writing, then through a vox unit wired to his brain.
