The X-Men's Krakoa Era is so great because it digs into every facet of the team's history. No one character has always been in the lead. Some characters are more popular than others, obviously, but the era has been stronger because of how many different characters it's showcased. Krakoa has redefined many characters, but few have been as changed as Apocalypse.
