He's a Spider-Man vigilante, 
He's Mexican and Irish, his dad is Irish and his mother is Mexican, he speaks Spanish fluently.
He's mean, a bully 
the genetic mutation that made him Spider-Man gave him fangs.
He responds to any and all insults with sarcasm. He doesn't take shit and doesn't like to play games so is straight forward.
He's calculative, doesn't trust easily and doesn't give out his identity. He's got black eyes and curly brown hair.
