- ❝ She ruined my bar mitzvah, I want her dead! Dead! Dead! Dead! ❞
- — Joshua Cobblepot
Joshua is Oswald Cobblepot's nephew. In the episode "A High Bar" when he turned 13, his family held a bar mitzvah for him and invited the Legion of Doom members to celebrate. Unfortunately, Harley crashed the bar mitzvah and since then he wanted her dead.
Joshua is a typical skinny white teenager, with three of his teeth being extremely misaligned and hanging over his bottom lip with braces connecting them. He has green eyes, three freckles on each cheek, and short brown hair worn in a comb-over-like style. He can sometimes be seen wearing a Kippah as he is Jewish.
- He claimed to have fingerbanged a girl at camp but he actually never did that.
- He is known to be quite impulsive.
