Alphonso Arachno is the art teacher at Fear High. He was always a depressed guy. With over four hundred siblings, he always seemed like no one noticed, or cared, about him. To be different from his siblings, Alphonso decided he would become a painter. With four arms, he could be doing many things at once and therefore made lots of paintings simultaneously. His creations were truly works of art and everyone loved them. Even his cannibalistic siblings would stop eating each other to marvel at his masterpieces. However, Alphonso was never satisfied with himself or his skill. One day, sibling #234 suggested he present his masterpieces at an art gallery. At one art gallery, he met his abusive girlfriend and at another, he met -insert teacher here- who told Alphonso they had an opening at Fear High for an art teacher and said he should apply. He applied and immediately got the job, and he still works at Fear High today. With eight eyes, he can always see what every student is doing so he always knows which ones are misbehaving. To punish kids, he ties them up in webs so they can't move. Additionally, he is never impressed with any of his student's work because he thinks their pieces are much worse than his. Mind you, he thinks his beautiful paintings are awful.
His creator made him 6 feet and 4 inches tall because the Giant huntsman spider is 4.6 centimeters tall, but if you changed the units to feet that would still be too small, so the digits were switched.
