Season 1

After causing him nothing but trouble, Stanley Ipkiss gets rid of his mask by burying it in quick-drying cement, but must retrieve it to save Peggy and Milo from Pretorius.

Pretorius tricks Stanley's friend and co-worker, Charlie, into building a "house of tomorrow". The Mask must stop him and save Peggy, Charlie and Milo.

When Stanley reluctantly agrees to baby-sit for his neighbors, the mask somehow gets on Baby's face...producing Baby Mask!

When Lt. Kellaway suspects that Stanley and The Mask are one and the same, he handcuffs himself to Stanley in order to keep an eye on his every move.

Stanley discovers a fabled "sister" mask that, when joined with his mask, allows him to control his wild alter-ego.

Shadows are being stolen from all over Edge City! And everyone whose shadow is stolen loses his or her youth and starts to age rapidly.

Stanley falls in love with a very shy woman...but her shyness evaporates when she accidentally dons the mask.

Stanley tries to add some excitement to his life by using "reverse psychology" to let the Mask's personality come out of himself.

Stanley's psychologist, Dr. Neumann, won't believe that Stanley is The Mask. Out of frustration, Stanley shows his therapist the mask, not expecting the doctor to put it on.

Stanley is so upset with Edge City's government that his alter ego, The Mask, campaigns for mayor!

When a top-secret government agency believes The Mask to be an alien, Stanley must not only contend with his nemesis, Lt. Kellaway, who believes The Mask is a criminal, but also Agent X.

Milo dons the mask to go after an evil dogcatcher who turns out to be a wanted felon.

Skillit returns on Halloween! He's back to claim the mask and pay Stanley back for being put in a school for delinquents.

Kablamus, Walter, and the Terrible Twos are all disguised as Santa Claus to commit crimes. It's up to the Mask to clear Santa's name.

The Mask breaks in half during Walter's attempt to retrieve it. Now both Stanley and the Mask are existing at the same time. Chet Bozzack, an old high school bully of Stanley, gets and puts on the other half of the mask.
