This is another series from the 1990s. The story arc starts after the conversion of Jean Grey into the Phoenix, and ends just before the Dark Phoenix Saga begins. There’s actually a lot that happens in this arc, including the Mutant-X  and the debuts of Kitty Pryde and Dazzler. Jason Wyndgarde, Sebastian Shaw, Emma Frost, and the Hellfire Club are also introduced. Even though the artwork leaves something to be desired, this arc represents a fairly important segment of X-Men lore and was certainly worth reading.
