Transformers: TransTech/Nightmare Fuel

Transformers Trans Tech

And even if you're allowed to leave Axiom Nexus (Eventually. Once you work through all the proper paperwork and fees.), the TransTechs have full control over where they send you. Which can involve "an approved alternate reality" instead of your real home universe. ""There were things that defied known science that lived within the void of transwarp, creatures of pure malice that could not exist within the material plane. It was virtually impossible that the second stream contained any of these extraplanar creatures, but their taint could affect material beings; such 'avatars' did rarely appear, and were capable of incredible destruction for the unwary and unprepared.""
 * The entire concept of being a "unit of interest". After arriving in Axiom Nexus via an Applied Phlebotinum accident or a Negative Space Wedgie or such (it's implied few end up there on purpose), you get told that due to the crime of simply having technology in your body that's special or unique from the TransTechs' POV and you were probably created with (or otherwise can't easily remove), you'll never be allowed to return home and must stay in Axiom Nexus for the rest of your existence. ...Under surveillance. And that's if you're lucky. If you're less lucky, you may be imprisoned in some manner. And if you're not lucky at all, you'll be Strapped to An Operating Table and subjected to experiments so the TransTechs can study you.
 * Even if you're not a unit of interest, you get implanted with an "identification card" which contains detailed personal information on your body capabilities and personality, can be read easily by any TransTech even without your permission, and can be used to track you.
 * The possibility of meeting up with members of the local La Résistance, with a mech that can forcibly swap or extract your very spark from your chest, and a leader who thinks the resulting Empty Shells make good ceiling decorations.
 * The possibility of meeting up with other people who have alternate modes that resemble metallic Eldritch Abominations.
 * The fact that, as oppressive as the TransTechs' security is for anyone they deem different, it's almost arguably justified, since:


 * And the entire story of "I, Lowtech" is basically pure Nightmare Fuel from start to finish. Since it's a bleak Sanity Slippage Protagonist Journey to Villain story that tells of a law-abiding TransTech executive ending up in the wrong body and going slowly insane and turning into a violent serial killer in his quest to survive in the dregs of Axiom Nexus and find out what happened to him. All told from the first-person POV of the mech in question, who is convinced to the last that he's actually the Only Sane Man in the deal. And Word of God has it that the story was actually toned down from the initial outline, despite the fact that it is still easily one of the Darkest and Edgiest stories in the Transformers mythos.
