This article is about a Alien Planet with Element Humanoids and/or other Intelligent Lifeforms affiliated with our Planet called Earth and they have a Terran Colony in the other zone in that Element Humanoids' Home Planet

The Planet Mewni is Star's home dimension. It is a land with a kingdom ruled by the King and Queen, and their daughter, Princess Star Butterfly, is the heiress to the throne.

General description

Mewni looks like a typical fairytale locale, with various magical creatures and a royal family. So far, the only notable nobles are the Butterfly family.

However, as seen in "Diaz Family Vacation", outside of the castle, Mewni's citizens don't seem to have the best conditions of life: the streets are rather dirty, with seemingly widespread poverty.

Beyond the Butterfly family's kingdom is a swampland, where Mewni's indigenous monster population were forced to flee after the first settlers forced them off of their land.

In Star vs. The Forces of Evil: Siege on Mewni, they've stolen Moon Butterfly's Wand and they're using it's power in the Giant Laser Planet Cannon at the Death Star to destroy Mewni for keeping Human Race out of their range from extinct Mewmans, but Carlos Omar Barrios is the Chosen One and Leader of The Midnight Resistance Ops who must infiltrate to the Death Star, put the Resistance Piece into the Stolen Royal Magic Wand and Save Mewni from the dangerous COMMANDARMY-ism Act and all Adriehl Concepcion INC. for the future of Mewni and the Inhabitants.

After AWESOMEADRIEHLX's death by a Laser Shot or a Magnum Bullet, Mewni will have a Human Colony in the Eastern Hemisphere for the new Global Military Service Agency called "MFATFSC" (Acronym for Mewnian Fairylanders Action Task Force Space Command on COMMANDARMY-ism Act and Alien Invasion, replacing the defunct AMS (Aiding/Anti Military Services)) when always ready to help, serve the rich, the poor, weak, defenseless and the innocent protecting Mewmans from the cruelty, evil and tyranny of the Alien Monsters of Haunted Wasteland Forest of Ludo's Empire, because those battles are Sci-Fi-Fantasy-Like battles between Alien Mewnian Monsters and Mewnians-Terrans.

But Connor Clayton Robinson/Warrior X now an Almighty God in enrage of AWESOMEADRIEHLX's death lead a Huge Armada Space Fleet by surrounded the planet with AWESOMEADRIEHLX's Firends and armies to bring mewmans and his enemies to extinction by glassing it, bomb it and more in Starco Kids' Adventures: Heroes of Tomorrow with his new sidekick with artificial life, Gunner-Bot
