“After countless exposure to biotomic energy, all testing proves negative. No enhanced abilities, no physical mutations, no nothing! It seems you shall never become anything more than a mere ducky!”
Mandark, Quackor the Fowl

Quackor the Fowl, whose real name is Ducky, is Mandark's pet duck, Monkey's girlfriend, and the former secondary antagonist of Dexter's Laboratory. She first appeared in an episode named after her and is voiced by Frank Welker.


Quackor the Fowl[]

In its first appearance in "Quackor the Fowl", Mandark performs the same experiments that Dexter performs on Monkey but finds nothing unusual about Ducky and decides to bring it to show and tell. Later that night Ducky overhears Mandark's desire to destroy Dexter's laboratory, so it becomes Quackor and begins to destroy the lab. The racket wakes up Monkey, so he becomes his alter ego and tries to communicate with Quackor, but this leads to fighting. After a while it is revealed that they are evenly matched, and the fight lasts all night. Upon seeing the sunrise, Quackor turns back into Ducky and flies back to Mandark's house. Dexter and Mandark try to show off their pets' tricks in class, but they are too tired from fighting to do anything.

A Quackor Cartoon[]

Quackor returns in "A Quackor Cartoon"; the beginning is quite similar to the previous episode and it and Monkey fight until Monkey punches Quackor so hard it lays an egg, revealing Quackor to be female. Upon realizing this, Monkey falls in love with her and they go on a date at the end.


Quackor is a yellow duck with big eyes, an orange beak, orange webbed feet, and some tiny yellow feathers on top of her head. When she goes into her supervillain form, she wears a black suit with a green ring around her neck that covers her whole body except for her beak and eyes, as well as green boots. She also has a green letter Q on the front of her suit.

In seasons 3 and 4, Quackor had eyelashes that are only visible in her normal duck form and her suit is shinier.


Mandark - Mandark is the owner of Quackor, and she is loyal to him. After she starts dating Monkey, Mandark and Dexter faint in shock when they see them.

Monkey - At first, Monkey and Quackor were enemies and would fight, but later in the series Quackor revealed herself to be female and she and Monkey fell in love, leaving Dexter and Mandark in a state of shock.


  • Quackor made a cameo in the Powerpuff Girls episode "Bought and Scold". The Narrator was mentioning all of the villains and describing them in one word, and Quackor was described as "Foul".
  • Although Quackor is female, she is voiced by a male voice actor.
  • In costume, she resembles Daffy Duck from Looney Tunes.
