He became a chimera when he was still in the womb. However no one, not even Stiles himself knows about this. Stiles is a mix of 4 creatures a werewolf, werecoyote, werejaguar and part kanima. He has the venom in his claws but can't grow a tail or get the scales.
He is the son of Sheriff Stilinski and Scott McCall's best friend. He was the first member of the Teen Wolf Pack and continued to help Scott throughout high school as he faced the various complications of being a young werewolf.
Stiles returns to Beacon Hills after being missing for two years, following his traumatic and secret transformation into a vampire.

Stiles's aptitude for learning and putting puzzles together is where most of his power comes from. These abilities are what draw the members of the McCall pack to him. They trust Stiles to form their plans and figure out their next step, despite him not having any supernatural abilities.
Stiles Stilinski is actually Mieczyslawa Mikaelson, one of the Original Vampires. She had been living a relatively calm life but that was until her twin brother, Kol came back in her life asking her to finally return to their crazy, diabolical family.
Stiles gets infected by vampire blood. According to a really old Russian text, he could become a blood-sucking monster like Bram Stoker's Dracula, an incubus-like blood-sucker who needs blood and sex to survive, or he could literally drain people's souls.
In Season 3, the Nogitsune is a 1000-year-old Void kitsune spirit that takes possession of Stiles Stilinski as 'Void Stiles' to cause chaos and strife throughout Beacon Hills, California.
Stiles and Allison move to Beacon Hills where they discover family secrets. Madness ensues. Stiles finds out he is one of a set, and his twin is a total player. Stiles has a twin named Genim.

His sacrifice during season 3A resulted in a change within him that let in a dark entity. It wasn't until a few episodes into season 3B that we got confirmation of Stiles' nogitsune possession, but once it was revealed, it was no holds barred from then on.
Stiles is a new witch, living with his cousins, Allison and Lydia, at the Deaton Manor.
Humans. Humans do not possess any known resurrection power, but it is possible for them to be resurrected through the Surrogate Sacrifice Ritual. This is best shown by Stiles and Allison both being resurrected through the use of the ritual, alongside Scott when they were trying to discover the location of the Nemeton.
He ended up having to take a lot of time off to recover and his shifting schedule caused him to miss out on taking part in much of the final seasons of Teen Wolf. Fans have missed Stiles' awkward and witty personality SO MUCH.
And considering that he has purposefully designed a world where we're asked to judge people with no underlying assumptions; it's completely logical to gather that Stiles is indeed bisexual.
When Stiles was possessed by the Nogitsue he presented with many of the same symptoms as his mother with the terminal condition frontotemporal dementia. Frontotemporal dementia has an hereditary element, but it missed a generation in Stiles. This was proven when he had a brain scan which was negative.
Scott is undoubtedly one of the strongest werewolves in Beacon Hills, something he's proven to his adversaries on multiple occasions.
Nogitsune. The dark kitsune ranks as the strongest creature in Teen Wolf simply because it has more abilities than any of the others. Despite being a variety of kitsune, it clearly has much more power than both Kira and her mother.

“I was looking for a Polish name that was incredibly difficult to both spell and pronounce. Mieczyslaw sounded like 'mischief. ' It seemed like a perfect word to describe Stiles -- both as a mischievous child and equally misbehaved adult." So there we have it -- this lingering case is closed.
