Karen Sharon Nancy Lydia Guy is the current wife of Brooklyn T. Guy. She is the tertiary antagonist of "Home Alone 2" and "The Purge!", the main antagonist of The Life of Brooklyn Guy!, and the secondary antagonist of "Jeffy Goes Bowling!".
She seems to be an on and off recurring character as of Elaina's return.
Karen has been shown to be very oblivious, dimwitted, loud, and very obnoxious in all videos she's in. She always annoys her husband, Brooklyn T. Guy.
Karen also appears to be extremely whiny and childish as she complains about her mask in Home Alone 2!
Despite being very dumb she is actually mentioned to be good at making clothes as in Bowser Juniors Christmas Eve! where she made Simmons elf costume to rob Junior's apartment.
- In “Ratatouille”, her name was revealed when Brooklyn Guy says, "Oh Nancy, you can come out now," when he jokes about his wife being a rat.
- However, her name is Sharon, as mentioned in “Jeffy Has Hiccups!” by her husband and in her appearance in “Black Yoshi's Mistake!”.
- From “The Life of Brooklyn Guy!” onwards, her name is confirmed to be "Karen". Back when her real first name was not confirmed, Brooklyn Guy referred to her as Karen in Jeffy Gets Chicken Pox!.
- In many episodes she's in, such as “Black Yoshi's Mistake!”, she is seen calling her husband, Brooklyn T. Guy, "Boiny".
- It is not confirmed if that is his real name but if it isn't it is unknown why she calls him Boiny. It is likely that she calls Brooklyn Guy Boiny as a nickname for him.
- It's also been speculated that Brooklyn Guy's real name is "Bernie", since she pronounces it "Boiny" due to having an exaggerated Brooklyn accent. However, Brooklyn Guy confirmed that his full name is indeed Brooklyn T. Guy.
- There is an alternative puppet of her as a mermaid which was first seen in “Jeffy's Magical Pencil!”.
- Robbery: In Home Alone 2 and The Purge! she breaks in the house with Brooklyn Guy and Simmons.
- Lying: In Bowser Junior's House Party! She lied to Junior and Joseph that Jeffy did something he did not do.
- Cuff Abuse: In the end of Bowser Junior's House Party! She cuffed Jeffy for no reason.
