Mack

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

- Mack

Mack is a lieutenant of the Smithy Gang and the boss of the first chapter of Super Mario RPG: Legend of the Seven Stars. Mack commands an army of Shysters and can use fire magic. Like the other members of the Smithy Gang, Mack is modeled after a weapon (in his case, a knife) and he is named after the song "Mack the Knife" (originally "Die Moritat von Mackie Messer" in German).

History
With his Shysters, Mack attacked the Mushroom Kingdom while Mario was in Bandit's Way. Mack occupied the throne room of the Mushroom Castle while his Shyster terrorized the residents of the surrounding town.

After returning to town, Mario and Mallow fought their way to the throne room and defeated Mack. Following Mack's defeat, the two remaining Shysters left to inform Smithy of Mack's destruction.

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

In the ending parade, Mack, along with Bowyer and Yaridovich, is seen being pounded by Smithy's hammer.

Battle
At the start of the battle, Mack is accompanied by a quartet of Shysters Bodyguards. If they're not defeated within one turn, Mack will jump out of the battle screen and will not return until all bodyguards on the field are defeated. When in battle, Mack attacks with physical strikes and the spells Flame and Flame Wall. After a few turns, the Shysters will return, requiring the player to repeat the process until Mack is defeated. If all the bodyguards are defeated, Mack will use Flame Wall for his next attack.

Physical appearance
Mack is a red-colored, roundish figure who holds onto a pair of handles on top of a giant knife with floating eyes (or may be the knife itself), mirroring how the Shysters and their derivatives ride on pogo sticks. When attacking, Mack shakes his head.

Trivia

 * When Mallow uses his Psychopath ability on the Machine Made version of Mack, he will say, "Mario! I'm BAAAAAACK!". However, the Machine Made versions of Mack are copies of him, not rebuilt versions of the original.
 * It is possible to skip the Mack encounter with a trick involving a tricky jump from a Shyster over to the Chancellor, who is hiding in the corner. The Shysters won't notice Mario, thus the fight will not be triggered. Mack and his gang will be gone after speaking with the Chancellor. The game will continue as normal, though the first Star Piece won't show up in the menu until after the second one is obtained since it wasn't formally collected.
 * You can sneak up behind the shysters to skip Mack and the shysters talking
