David "Dave", also known as Accordion Dave, is a member of Der Monster Klub and a student who attends Norrisville High.
Appearance[]
Everyday[]
Dave is a brown-skinned boy with a thin build, soft black hair, some mustache above his lip, and slanted, droopy dark green eyes. His normal attire is of a black T-shirt, green pants with red accents and white suspenders, and black soled white shoes.
Monster Form[]
When stanked by the Sorcerer, Dave turns into a light blue, human-like monster with pale yellow eyes. His muscular, accordian-like arms can shoot out far distances at a fast speed to punch things.
Personality[]
Dave plays the accordion, and is rather talented at playing it. He speaks with a Hispanic accent.
Personality-wise, he doesn't seem as over-dramatic as his fellow classmates and seems to handle things fairly well, but gets stanked anyways, most likely due to internal panicking that he doesn't show too much on the outside.
While quieter and less expressive, that doesn't mean Dave doesn't get along well with others, and he actually has a good amount of friends, including his Klub pals and Howard.
Relationships[]
Der Monster Klub[]
Dave is generally good friends with the Klub, who are fellow outcasts. However, he was emotionally hurt by Julian exposing his secret enough to get stanked, although he seems to still be on good terms with Julian afterwards.
Randy Cunningham/Norrisville Ninja[]
Dave doesn't have any particular opinion towards Randy, other than knowing Randy is Howard's best friend and vice versa, even though they sometimes get along and hang out together. Nevertheless, after being trapped on the school roof by Randy, he knows that Randy isn't someone to be messed with, and that he shouldn't interfere with Randy's friendship with Howard.
Like the rest of the town, Dave is unaware of Randy being the Ninja, but still treats the masked hero with admiration and respect. But there are instances of him teasing the Ninja, such as in "To Smell and Back" when he and the rest of the school laugh at and make fart jokes about the Ninja.
Howard Weinerman[]
Dave and Howard don't have much bad beef, even though Howard usually finds him uncool and only hangs out with him for benefits. Dave does find Howard's gross sense of humor disgusting at times, as seen in "To Smell and Back".
Bash Johnson[]
Dave was once played like an accordion by Bash because he resents Dave's skills. Due to this, he resents Bash, and he enacted revenge on his bully after he got stanked in "Der Monster Klub".
