Pet name: Knyle Ryvir
Personality: Being the middle child of an odd union, Knyle never ended with with the parental attention he desired. Not that he was ignored completely, but with his sister's want to be a warrior like his mother and his brother being sicker then the average kit, he always felt like he got the short end of the stick, but felt that his siblings were more noticed for a reason, so mainly just stuck to the shadows. He's quiet but overly confident in himself and his abilities, and likes hitting on guys, mainly to get a rise out of them.
Why would he/she want to join the family? Despite being the least noticed child, he's drawn to families, and would find Bryson's slightly reminiscent of his own odd family. That, and he finds Bryson very attractive. He has a thing for spots of any sort. That and Bryson and he would probably play argue half the time (which I myself find adorable, but I'm weird)
What could they bring to the bloodline? Edits, shadow/ghost and fairy type abilities, a new bloodline (he is the son of a pokemon and a fairy warrior after all)
