Crouch Sr. makes his first appearance in the series at the Quidditch World Cup in "Goblet of Fire", when he attends the Quidditch World Cup with his house elf Winky as well as Crouch Jr., who is hidden under an Invisibility Cloak. Due to Winky's fear of heights, Crouch Jr. is able to slip away and steals Harry's wand to conjure the Dark Mark. When Winky is subsequently caught by Amos Diggory with Harry's wand, Crouch Sr. angrily dismisses Winky on the spot for failing to keep his son under control, as it was her idea to let Crouch Jr. attend.
