Calls for what Parrish might be:
I’m seeing pheonix or kasai (fire kitsune) an awful lot, and out of the two I’m inclined to say that kasai has more weight behind it, because Kira and Parrish have the same eye colour when their powers are flaring up. However, for the sake of argument, I’d like to throw some other possibilities into the ring:
Ifrit/Jinn: An Arabic spirit related to/made of fire (but also corporeal). Known to be quite intelligent and associated with riddles/puzzles, which could go with the bomb defusal. I know Parrish is not Arabic/Middle Eastern, but I don’t think the fandom theory that people can only be animals from their culture has much sway - Meredith wasn’t exactly Celtic, and the Kanima was supposedly from South America, which doesn’t match Jackson.
Cherufe: Chilean creature of magma/fire, either humanoid or snake-like depending on the source. I don’t think this is a likely option, partly because it’s not well known enough to attract attention, but also because they’re traditionally evil creatures that cause earthquakes and volcanic eruptions unless given human sacrifices.
Salamander: For me, this was my first thought after the car fire. Salamanders are lizard-like creatures, based on real creatures also called salamanders (which are really cool and you should totally check them out). Salamanders are consistently reported as being able to live in fire, and even as gaining sustenance from it. Their whole gig is fire, as compared to the phoenix to whom this is just one part.
Dragon: We all know the drill here.
Hellhound: Traditionally associated with fire, due to the whole Hell being on fire thing. Perhaps it’s a variety of werewolf?
Cyclops: Again, a bit of an outside shot, but they are heavily associated with smithing and forges, which are obviously full of fire.
So, all things considered, I’d put my money on Kasai because of the fire thing, but failing that, salamander.
