Smithy Gang

The Smithy Gang is an evil criminal organization that is located on the Mushroom Kingdom continent. They are led by the evil Smithy, and he leads a large army of mechanical monsters that he uses to attack the Kingdom, Toad Nation, and Northern Wastes. He also steals some of the Airships that Bowser and the Koopa Troop use, and used them to get to other places, such as Yoshi Island, Sarsaland, and Koopa Kingdom.

Invasion
Smithy, leader of the Gang, was a thief who led a small group of bandits when he found a large mechanical robot factory in the northwestern Toad Nation. He turned it back online and created a large army of mechanical creatures. Smithy made all of his bandits commanders and advisors. Then, he conquered the nearby villages and attacked the capital, Toad Town. Toad Town was only guarded by a few Toad soldiers, sense most of them were off at war against Bowser. After conquering Toad Town, he started his campaign to take the rest of the continent.

He used the factories to make more robots and gave them mounts, which were tamed creatures. By this time, only a little bit of the northern part of the Nation was unconquered by Smithy. They informed Princess Peach, who sent a message to all other nations, including the Northern Wastes, Bowser's domain. Smithy sent in hordes of robots and other minions that took the half the Mushroom Kingdom.
