Serialised last year (but collected in March), this was easily the biggest superhero event weâÂÂd seen in quite some time, and probably the most seismic shift in the status quo of MarvelâÂÂs mutants since Grant MorrisonâÂÂs explosive run nearly 20 years ago. Jonathan Hickman, along with artists RB Silva and Pepe Larraz, simultaneously embraced and turfed out recent continuity with this meticulously plotted tale that sees Charles Xavier execute a bold, potentially crazy plan for mutantkind. With story threads running in the past, present and far flung future, itâÂÂs both a gigantic reset button for a corner of the Marvel universe that had been overlooked for some time, and an exciting, original story filled with the kind of jaw-dropping beats that you want from top-drawer superhero entertainment
