Who is the alien villain of Super Mario Land?

Tatanga is the alien villain of Super Mario Land.

In Nintendo's 1989 Game Boy adventure, Tatanga invades Sarasaland, hypnotizes its inhabitants, and kidnaps Princess Daisy. Mario travels through the kingdom's four regions to rescue her, making Tatanga a major departure from the Bowser-centered plots of many console Mario games.

Tatanga is also the final boss of Super Mario Land. He appears after the preceding boss, Biokinton, and fights Mario while piloting a spacecraft. The game's unusual setting, alien antagonist, and newly introduced Princess Daisy helped distinguish it from the original Super Mario Bros.

Players sometimes confuse Tatanga with Fawful or Smithy, villains from Mario role-playing games, or with Wart, the antagonist of Super Mario Bros. 2. Tatanga later returned as a boss in Super Mario Land 2: 6 Golden Coins, where he is associated with Wario's schemes.
