Panser

Pansers are enemies commonly found in Super Mario Bros. 2. Along with Pokeys, they are the only known hostile plant species in Subcon, although Pansers were created by Wart. There are four types of Pansers: red, green, gray and pink. The red version stays in one place and shoot three fireballs in the player's direction, green and gray variants (or just green in the remake) patrol an area and shoot fireballs straight up, and the most powerful, the pink (blue in the remake), chases the player and shoot three fireballs. These enemies can only be defeated by throwing another enemy or a Mushroom Block at them, and are sometimes an excessively annoying enemy.

They are much like the Volcano Plant and the Lava Lotus of later games. A key difference between Panser and the Lotus enemies is that the former walks and is more aggressive, whereas the latter are immobile and seem to be defending themselves. The Pompon Flower of Super Mario Land and the Pollen Plant of Virtual Boy Wario Land are also similar.

No actual Panser is found outside of Super Mario Bros. 2, its remakes, and other related media. Nonetheless, in the racetrack titled Shy Guy Bazaar from Mario Kart 7, many stalls (and even part of the track itself) are decorated with red carpets, all of which feature Panser sprites as motifs, along with Phantos and Cobrats.

In the NES version, they have black stems, but in the SNES version and other subsequent remakes, they have beige stems. The red ones are always depicted as having green stems in artwork.

Trivia

 * Excluding Wart, Pansers are the only enemy from Super Mario Bros. 2 to not appear in The Super Mario Bros. Super Show!.
 * Pansers likely get their name a combination of the word, a type of flower, and , a German tank, perhaps in reference to the plant's ability to throw fireballs.
 * In Super Mario Bros. 3, the game's sole Fiery Walking Piranha at the end of World 7-8 acts similar to a red Panser but shoots four fireballs instead of just three.
