This is what I imagine Oy from The Dark Tower looks like.
Tweak was a furry alien who played a major role in “The Cursed Earth”.
After humans arrived on his home planet, Tweak arranged for his people to go into hiding underground until he could gather more information about them. After utilising the power of mind probes he was able to determine that human history was littered with violence, exploitation and hatred - so, as President of his world, he decided that no contact should be made with the humans at all.
After his children were captured, Tweak decided to let himself be captured and posed as a ‘dumb alien’ rather than risk the humans exploiting the vast mineral resources of his planet - which Tweak’s people ate - and leaving Tweak’s race to starve. Convincing the humans he was unintelligent, Tweak and his family were sold into slavery in the Cursed Earth, although he was separated from them. After escaping and finding his family dead Tweak was recaptured but escaped again, thus the Slay-Riders were employed to kill him. Judge Dredd stepped in to save the alien, upon which Tweak helped him to deliver the 2T(FRU)T virus antidote to Mega-City Two. After the mission, Dredd arranged for Tweak to be returned to his home planet. Dredd insisted the planet was of no value, and Tweak’s people were left in peace
