Martin Coslaw (Cycle of the Werewolf)

All of those, and one ten-year-old boy named Martin Coslaw in the doghouse until Christmas, most likely. He pushes the Black Cats further up on his lap, gropes happily in the bag again, and comes out with the biggest twizzer of all - a World Class Twizzer if ever there was one.

Blaze's abusive adult arithmetic teacher and Cycle's ten-year-old boy share Martin Coslaw's name but are different depicted identities.
