Kreciold is an aggressive high schooler known to be a slacker at school, has no care for the world or others, and will beat the crap out of anyone who sets his fuse as he is hot-headed and stubborn. He usually avoids his severe mentally disabled family members such as Sunday and Guppy, because he knows that their brain functions are extremely broken and constantly makes a lot of noises, both object and vocal. He also sees them as disgusting (which is unfortunately the truth) and will put them in their place should they annoy him. Yep, he will beat the crap outta them should they annoy Kreciold. As time pass, however, he begins to become a little bit more soft and is becoming like a loveable brother while still keeping his personal attributes. And yes, that includes his severely mentally disabled family members ex: Sunday and Guppy etc. you get the idea.
