Mutant X #25

Mutant X #25, released in 2001, serves as the final issue of the series created by Howard Mackie. The comic occupies a unique space in the Marvel Multiverse, following an alternate reality version of Havok as he navigates a landscape where his brother, Cyclops, was raised by Mr. Sinister and he himself leads a group of super-powered outcasts. This issue was written by Mackie and featured art by Tommy Lee Edwards, concluding a narrative arc that leaned heavily into the darker, more speculative tropes common in the late 1990s and early 2000s Marvel output.

The creative direction for the series aimed to provide a self-contained environment distinct from the primary X-Men continuity, allowing for significant character shifts that would have been prohibited in the main books. While the series was generally viewed as a commercial experiment in world-building, the conclusion of the twenty-fifth issue provided a definitive end to the Havok-centric storyline. It is often noted by collectors for its distinct stylistic departure from the house style of the era, reflecting an effort to distinguish the 'Mutant X' universe from the rest of the X-Men franchise.
