X-MEN #261 (1990) – 1ST FULL APPEARANCE OF MARROW & THE MORLOCKS!

X-Men #261 (May 1990), a key Copper Age issue featuring the first full appearance of Marrow, one of the most recognizable members of the Morlocks and a character that would go on to play a major role in X-Men storylines for years to come.

This issue delivers everything fans love about late 80s/early 90s X-Men—gritty storytelling, intense action, and the darker tone that defined this era. The introduction of Marrow and the Morlocks adds depth to the underground mutant world, expanding the X-Men universe beyond the core team and into more raw, street-level conflict.

The cover is absolutely iconic—featuring Wolverine front and center in a brutal, chaotic battle scene, surrounded by danger and tension. This is peak Jim Lee-era energy building toward the explosion of X-Men popularity in the early 90s.
