Howard can be described as a loyal, loud-mouthed lazy guy. He is also very emotional when his food is ruined or damaged. It is also revealed that he is aware he is less intelligent than Randy, since he laughed with Randy when Randy suggested for Howard to try and come up with an idea, though he has shown some intelligence, as he knew how many Scoville units a Habanero pepper was in "McFists of Fury". He can also be a jerk, as shown in "So U Think U Can Stank" when he aggressively rejects participants for little to no reason, thus turning them into monsters. He also gets angry at Randy often, since it appears that his fault is the cause of their arguments.
Howard, unlike Randy, is somewhat more chubby, which comes from laziness. He has orange hair like his sister Heidi. He is almost always wearing a T-shirt with a squid on it.
Role in the series
Howard has been Randy's best friend for a long time. During the summer vacation before school began, they both played Grave Puncher, Grave Puncher II, and Grave Puncher 3.
Last Stall on the Left
When they first came to school and had to write a 500 word essay, Howard asks Randy if he can copy his. Randy says no because he does not want them to turn in the same essays. Mr. Bannister then throws his right shoe at Howard because he talked.
The next day, they get out of class, and he starts talking about how the ninja had not shown up yet. Randy says that it does not really matter, but then Howard states that they are his number one fan.
During lunch, Randy goes to the bathroom. Howard then yells to him that he will eat his tater tots if Randy does not get out. Randy then Smokebombs in wearing the ninja suit. He tells everybody that he should be able to fight a monster anytime. He is about to leave when Howard holds onto him and tells him to wait until Randy gets out of the bathroom.
Krackenstein then attacks, and Randy gets knocked into a locker. Howard texts Randy that the ninja was getting pwned.
When class begins again, Howard tells Randy that they were supposed to meet the ninja together. He also says that he thought the ninja was terrible. Randy states that there is no encyclopedia of how to be a ninja, which gives him the idea that he should look in the NinjaNomicon. Randy says that he has to go to the bathroom, but actually goes home to check the NinjaNomicon.
When class is over, Howard finds the Krackenstein and releases it so he can see the ninja again. He meets Randy and tells him about what he did. Krackenstein destroys the wall, and they both go out to see Krackenstein destroy Principal Slimovitz's car. Randy gets away from Howard and turns into ninja mode. Howard then watches Randy fight Krackenstein and this time win.
They then meet behind the school, where Randy tells him that he is the ninja.
He and Randy are best friends, although they have arguments, and they always forgive each other.
