Balthazar Picsou, best known as Picsou, is Scrooge McDuck's name in Francophone countries. One of the most popular French comics magazines is named after him- "Picsou magazine". French comics magazines have an official Facebook page too, named "Picsou et Cie". Also the Disney comics wiki is entitled to him: "Picsou Wiki" -the equivalent of the English Scrooge McDuck Wiki. Also, the French title of "Ducktales" is "La bande à Picsou" ("Scrooge McDuck's group").
Balthazar Tiberius Cavendish is a character of the Disney cartoon series "Milo Murphy's law". He's always called by surname. His first name was revealed by the creators via Twitter initially. Then it was revealed in an episode of the show's second season. In the same episode it was revealed that his middle name started with T. Because the fans were curious to know it entirely, one of the creators twitted his middle name too.

I love this name. Every since Balthazar Getty guest-starred on Roseanne as Darlene's boyfriend. I like either spelling - with the z or with the s.
Balthazar is a character in Romeo and Juliet. He has a minor role, but you could argue that the entire tragic ending is all his fault. He's Romeo's servant, who he apparently trusts enough to tell him that he's married to Juliet. When Juliet takes the sleeping potion to make her appear dead, Balthazar runs away and tells Romeo that Juliet has died. Romeo then freaks out and kills himself in Juliet's arms. And as we all know, Juliet wakes up and then kills herself. Still a cool name, though--and besides; I'm sure that Shakespeare's poor Balthazar didn't intend to cause all this trouble. :)
