The X-Men have long been one of Marvel’s most iconic teams, representing the struggle for mutant equality and the pursuit of justice. Their legacy is ingrained in the very fabric of the Marvel Universe, and it's a title that seems impossible to replace. However, in X-Men #15, a new team is claiming the title of X-Men, and the preview pages for the following issue give us a taste of what's to come.

X-Men #16, written by Jed MacKay and illustrated by Ryan Stegman, introduces us to a group of villains who claim to be the X-Men. The preview pages show Scott Summers identifying the group as the Santo Marco Six.

The new group of mutants seems to display impressive powers, and their nickname suggests some heavy lore implications for their origin. These villains intend to claim the X-Men’s legacy as their own while working under the shadowy 3k.

These mutants are far from typical X-Men, and their connection to the mysterious villain team 3K adds an unsettling layer to their debut. 3K is a group with a clear, ominous goal: to prepare a "crucible" for a new world by forcibly activating the mutant gene in non-mutants. Their methods are questionable, and their ultimate intentions remain unclear. The involvement of the Santo Marco Six with 3K raises critical concerns about what they intend to do next. Clearly, the group’s methods suggest that their goals may be far darker than they let on.

As the story unfolds, it becomes apparent that the Santo Marco Six seek to create controversy surrounding the X-Men's legacy.

With their bold claim to the X-Men name, this new team is setting the stage for a dramatic clash over the definition of justice in the mutant world. The X-Men must now confront a new, potentially dangerous version of their own identity.

Despite their shocking debut, much about the Santo Marco Six remains a mystery. Their powers, true identities, and motivations remain unclear, making fans intrigued. Aside from their names, little is known about these new recruits, deepening the enigma. However, their nickname offers a hint regarding their origin.

Santo Marco was once briefly ruled by Magneto and then by a ruthless anti-mutant president, Augustine Duarte. The Santo Marco Six’s ties to this country suggest their mission could be more complex than just replacing the X-Men. The organization 3K, known for forcibly activating mutant genes in non-mutants, may be manipulating these characters as part of a larger agenda. With their name connecting them to Magneto and the Brotherhood of Mutants alongside their allegiance with 3K, these fake X-Men could be a massive potential threat.

Their arrival calls into question the very image of the X-Men and whether their ideals have been corrupted or misunderstood. Though their debut may feel jarring to long-time fans, there’s an undeniable excitement about the potential this new team brings to the table.

The clash between these two groups promises an exciting future for the series, and fans are eager to see how the dynamics will unfold in the coming issues
