Anyways, Loki was made after Frost bet me to change my username to a Zoroark, and we agreed to call the Zoroark Loki, originally he was just supposed to be Liam (real me) wearing a Zoroark suit but I decided to change that and build more lore around him for a character concept I've been wanting to try out.
Firstly Loki isn't an actual Zoroark, based on the real norse god of mischief Loki, he's not an actual god but instead the norse mistook him as one, Loki is a sentient abstract concept of mischief that doesn't actually have a true form, he exists as a formless part of the universe that just happens to have an intelligence and is able to invade the physical world by entering the body of a random living person/creature.
Although his main thing is causing 'mischief' and getting up to trouble a lot he's not exactly evil, his secondary motivation is just to learn more about the world and the people who inhabit it as he doesn't really know that much, thankfully empathy was one of the first things he learned.
As for his powers, he technically can't be destroyed since he's basically a personified idea with a nonexistent true form, but once he has entered the world through possessing a random person's body (For example someone named Liam ;3) he has a couple limited powers, his main one being shapeshifting, he can alter the physical attributes of his host to resemble any living creature that he has learned about, foxlike creatures like Eevee, or mainly Zoroark are his favorite form as humans often associate foxes as being tricksters.
When he leaves a host's body they will go back to their original form if he shapeshifted, so he can't make someone look like a Zoroark or whatever permanently, his shapeshifting is not to be confused with a Zoroark's illusions as his form changing is infact real. Also when in a physical body he can only take over another body if he physically touches them or if his host body is destroyed/killed he will immediately possess the nearest living being to him which is usually the one that 'killed' him. After leaving a host their body will be in a coma state for no more than one hour after which assuming the body has not been badly damaged they will wake up with no memory of being controlled by Loki.
