Shadow Sirens
A name you'll only meet on fan pages — Nintendo never gave this group a single sprite, a line of dialogue, or an in-game mention.
Zero official appearances. Nintendo has never shipped a game, published a story, or filed a document that names a faction called the Shadow Sirens. You won't find them anywhere in the lore built around Mario, Luigi, Princess Peach, Bowser, or any of their allies and enemies. This isn't buried canon waiting for a data-miner — the name simply doesn't show up in any source material Nintendo has produced. What you're seeing is straight fan fiction, or a muddle with some other entity someone half-remembered. The Koopa Troop, the Shy Guys, the assorted alien armies — those are the antagonistic groups Super Mario actually runs with. Shadow Sirens? That chair is empty.

Lore & Background
Because the Shadow Sirens are not part of the official narrative, there is no canonical lore to recount. The rich tapestry of the Mushroom Kingdom includes the ancient history of the Star Spirits, the recurring conflicts between the Koopa Kingdom and the Toads, and the cosmic adventures involving the Lumas and the Power Stars. In contrast to these well-documented elements, any story attributed to Shadow Sirens would be purely speculative. The official canon is careful about its magical entities; while there are ghostly figures like Boos or spectral warriors in specific games, no organized siren-like group with shadow powers has ever been introduced by the creators of the series.
In Their Own Story
The wind howled through the empty castle halls, but it carried no song. Mario stood alone, expecting a challenge that never came. There were no sirens in the shadows, only the familiar, friendly ghosts of the past and the distant roar of Bowser's army. The silence confirmed what every true fan knows: some stories are simply not written in the stars of this world.
Reader's Guide
Since the Shadow Sirens do not exist in official Super Mario media, there is no leadership structure, defined goals, or member composition to detail. No conflicts have been sparked by this group because they have never appeared in any game, comic, or movie produced by Nintendo. Any attempt to describe their impact on world conflicts would be purely imaginative and contradictory to the requirement of sticking to widely-known facts. The real factions that drive the narrative are the Koopa Troop under Bowser, the Star Spirits who grant power, and the various alien races from the Luma or Luminoth traditions. Fans may encounter this name in fan fiction or community role-playing scenarios, but it holds no weight in the actual history of the Mushroom Kingdom. The true story remains focused on Mario's rescue missions and the eternal battle against Bowser.
