Lady Di Archer (pronounced Ar-SHAY) is a villainess from the '90s cartoon Bruno the Kid. She is the main villain of the episode "The A-maze-ing Adventure".
Lady Di is an old enemy of Bruno's partner, Jarlsburg. Long ago, she stole a Hope Diamond, and Jarlsburg wasn't able to stop her. In the present day, she is now the powerful owner of a diamond mine. Not wanting it to be mined, she steals a ceremonial scepter so war between Jumai and Bakare will continue.
Lady Di hosts an archery contest. Bruno enters undercover and wins the shooting part. Lady Di, wanting to see if Bruno can bag live prey, has Jarlsburg brought as prey. Bruno avoids shooting him and wins, so Lady Di invites him to a feast. She locks Jarlsburg in a cell and later reveals her plan to kill him, but not before learning if Bruno is working with him.
Later, Lady Di traps Bruno in a maze and promises to let him out if he can brave three dangers. After braving the first three dangers, however, Bruno falls into a trap, whereupon Lady Di reveals she lied about there being three dangers.
She traps Bruno along with Jarlsburg and chains them with diamond chains. Fortunately, Bruno remembers that diamonds have air pockets and has Jarlsburg lift his hands, reflecting light off of glass and into Bruno's chains, freeing him. Bruno frees Jarlsburg, and the duo escape (with little difficulty, as Bruno had jammed the door with gum earlier). They use dry ice to lure Lady Di out, and when she tries to grab it, Bruno intercepts the scepter and hurls her against her henchmen. Lady Di and her henchmen chase Bruno and Jarlsburg just as the duo jumps out of a window, but Bruno flashes the scepter at them, enabling him and Jarlsburg to return the scepter and end the war.
Lady Di Archer is one of the villains recruited by Von Trapp in the three-parter, "Bye Bye Jarly". She is put in charge of finding the most flawless diamond to operate Von Trapp's lasers. She finds Bruno, Jarlsburg, and Harris in a shed and attempts to grind them on a grindstone. After Lazlo Gigahertz turns off the power, Di and her fellow villains corner Bruno and Harris into an electric fence to electrocute them. Fortunately, Jarlsburg comes in and destroys Lazlo's device. Di and the other villains turn on Von Trapp and go chasing after him.
