Mack

"Listen up, gang! These guys are gonna put a stop to OUR party! Are we HAPPY about this?!"

- Mack

Mack is a member of the Smithy Gang and one of Smithy's lieutenants. He appeared in the game Super Mario RPG: Legend of the Seven Stars. Mack is in command of an army of Shysters, pogo-stick riding Shy Guys. Mack also wields powerful fire magic. With his army of soldiers, Mack attacked the Mushroom Kingdom and occupied it. Mario, conveniently, was in Bandit's Way with Mallow, chasing down the thief Croco. Mack allowed his Shysters to overrun the town, causing chaos as they wished.

When Mario and Mallow returned to town, they were shocked by the sudden appearance of the Shysters. Together, they rescued townspeople and fought to the throne room of the castle, where they confronted Mack and his elite Shyster Bodyguards. After a long battle, Mario emerged victorious, driving Smithy's forces out of the Mushroom Kingdom. In the aftermath, Mario earned his first Star Piece. On a related note when Mack is destroyed, the two remaining Shyster Bodyguards will leave to inform Smithy of Mack's demise.

Mack would return in Smithy's Factory, in the form of a gray mass-produced copy of the original.

Mack appears to be a large knife with floating eyes. However, there is also a red-colored figure on top of the knife holding the handle of the same as if it were a pogo-stick. When attacking, the red figure begins to shake its "head."

Trivia

 * Mack's name comes from the song, "Mack the Knife" (originally "Die Morität von Mackie Messer" in German). The song was composed by Kurt Weill, with lyrics by Bertolt Brecht, for the music drama Die Dreigroschenoper, or, in English, The Threepenny Opera. "Mack the Knife" was later covered by both Louis Armstrong and Bobby Darrin.
 * Jack the Knife, a character from Wario: Master of Disguise, has a name very similar to Mack the Knife. It's possible that his name also comes from the song "Mack the Knife".
 * When Mallow uses his Psychopath ability on the Machine Made version of Mack, he will say, "Mario! I'm BAAAAAACK!". This implies that one of the Machine Made versions of Mack is actually a rebuilt version of the original, rather than a copy like all the others.
 * Strangely enough, the ending seems to imply that the original Mack apparently survived after his defeat, as he, along with Bowyer and Yaridovich, were last seen in the ending parade getting pounded by Smithy's hammer.
