Shyster

A Shyster is a mechanical Shy Guy that hops on a sword-tipped pogo-stick. They appear in Super Mario RPG: Legend of the Seven Stars and work for the Smithy Gang. Shysters formed the bulk of Mack's forces during his invasion of the Mushroom Kingdom. After Mack conquers the peaceful kingdom, the Shysters are allowed to terrorize the townsfolk as they please.

A Shyster attacks by jumping on top of his opponent with his sword-tipped pogo-stick. Additionally, Shysters have limited proficiency in magic. As such, Shysters can use the weak fire-based attack Drain to shoot a small fireball at opponents. Shysters can be easily defeated with lightning magic.

During Mario and Mallow's battle with Mack, the knife monster summoned four Shyster Bodyguards. These Shysters are slightly stronger than the normal variety. However, they still can be defeated with lighting magic. Several stronger varieties of Shysters exist, including the Springer, the Machine Made Shyster Bodyguard, and the Shyper.

Shysters love nothing more than hopping around all day long.

Shy Guys riding pogo-sticks also appear in Yoshi's Story. However, these Shy Guys took advantage of normal-tipped pogo sticks rather than the seemingly stronger sword-tipped ones. They were most likely not mechanical creatures as well.

Trivia

 * Shyster's name, in addition to being a pun on "Shy Guy", is likely derived from the actual term "shyster", which really means "conman".
