Look, if I see a hella contest I’m up on it.
This is my submission for the Ava’s Demon design contest, a demon named Tengridan. Tenny is a technology demon, so most of your standard tropes apply. He has a nearly total lack of sympathy and empathy which is his great sin of sorts. Tengridan is born of computer data, meaning the physical form he takes (well, took) was highly unstable and dependent on how much electrical energy he could suck from his surroundings. Even in the best cases his form was still glitched. His original program model was devoid of arms (because who needs arms in cyberspace) but he found that in reality arms are a good thing to have.
-If you have a technology/electrical issue of any kind, Tengridan can fix it.
-If you’ve got a math problem, he can solve it.
-Tengridan is INCREDIBLY smart and quick-thinking. This and the above carry into the powers provided to his host during a pact.
-As mentioned above, he’s emotionally stupid.
-His body is unstable; he often makes his host tied to electronics of any sort to manifest.
-He wants to be truly real and alive like an organic being. Guess technical immortality isn’t what it’s chalked up to be. It’s something of a nearly impossible hamartia.
-This said, he’s only as strong as his code or the machine his program runs on. That’s how he “died” in the first place— his program was deleted.
-His name is an anagram of “integrand”. One because the whole math thing (his host’s pupils would be the integral symbol) and second because he integrates himself into reality.
-His mindspace is full of wires and screens. It’s typically not very welcoming but he can change it because it’s a sort of virtual reality.
-His wording can be very confusing because he speaks in code language, or at the very least, logic style. Idioms and metaphors are largely beyond him unless predefined.
-Individuals of his species are based on individual instances of his program. They are born when the program is installed and die when it’s deleted, uninstalled, or the machine junked/powered off never to be turned on.
