Iron Mam somewhat resembles an armored baby, with two blue plates above and underneath her head and Kirby-like eyes and blushes. She has blue spiked balls for shoulder pads, giant pink balls for hands, pink metallic shoes, and a pink bow atop her head.
Iron Mam attacks by using the two fist-like balls at her sides. She gives the Fighter ability when swallowed. Sometimes, she'll jump and make a star at her front which Kirby can inhale (though the star only appears in the remake).
Iron Mam also appears as the final competitor in the Megaton Punch sub-game.
Iron Mam appears as a keychain in Kirby: Triple Deluxe.
While Iron Mam does not appear in Kirby Star Allies, there is a bigger version called Grand Mam which appears as a boss.
