Wario Castle

Wario Castle is the castle that serves as the home of Wario in several games. In Super Mario Land 2: 6 Golden Coins, it was Mario's own castle which Wario took it to himself when Mario was away. During the events of the game, Wario cast an evil spell over Mario Land, brainwashing its inhabitants into becoming his mindless followers and ultimately transforming it into his own fortress.

After losing the castle to Mario, Wario was more determined to have a castle in Wario Land: Super Mario Land 3. The ending of the game depends on the amount of money the player earns in the game. Collecting a certain amount of treasures grants Wario an early version of the castle, but other outcomes include the smallest home which is a bird house, or the largest possible home which is an entire planetoid with Wario's face on the surface.

In the SNES version of Wario's Woods, a version of the castle makes a brief appearance in the heart of the woods. It is first seen as the final level of the game as it is the setting in where Toad, the game's protagonist must fight the other bosses, including Wario himself. The castle also appears at the end of game after Toad clears all rounds. As Wario rages on by plane, Toad throws one final bomb at his castle. The explosion of the bomb causes the castle as well as Wario and his plane to go crashing down in defeat. Unlike the NES version (which has a different ending), it is discovered that Wario's Woods has returned to peace, implying that the castle's construction was the source of the corruption of the forest.

In the first proper appearance of the castle, Wario Land II, Captain Syrup seeks her revenge and sneaks into it, stealing massive amounts of treasure from Wario early in the morning. She floods the castle and he spends the game in search of his treasure and the crooked captain which he eventually recovers.

In Wario World, Wario has fully finished the construction of his castle, now renovated with gold. His happiness with his wealth are short lived when a mysterious treasure that he stole named The Evil Black Jewel awakens. Black Jewel destroys Wario Castle and turns it into its own world in its own dimension, all connected through Treasure Plaza. To get his castle and possessions back, Wario traveled through the four worlds the Jewel created, which includes: Excitement Central, Spooktastic World, Thrillsville and Sparkle Land. Wario eventually manages to defeat Black Jewel and rebuild his castle, but its quality is determined by the number of Spritelings that are saved by the player on the adventure.

It has yet to reappear in later titles, although Wario Palace from Mario Superstar Baseball is a similar location. Wario is instead shown spending time in his smaller home.
