The Monday Family (named by Zak Saturday, see above) are evil doppelgangers of the Saturday family from an anti-matter universe. The only one to be totally physically identical to her real world counterpart is Drew Monday, though the evil Drew has an extremely long snakelike tongue. The other family members all have external differences- Zak Monday’s hair that is the inverted version of Zak Saturday’s, Fiskerton’s double has horns, Komodo has spots and the ability to turn into stone, Doc Monday has an eye patch over the opposite eye to Doc Saturday, and a fingerless version of the glove, and Zon’s double is shown to have eyes on her wings.
