The X-Verse is filled with fearsome foes, and these are some of the fiercest villains of all! Magneto, the Master of Magnetism, has world domination on his mind and the power to achieve it - but not if the X-Men can stop him! When the savage Sabretooth crashes Wolverine's birthday dinner, it puts the love of Logan's life in danger! As the ages-old history of Apocalypse is told, he unleashes his Four Horsemen on X-Factor - and one of them is frighteningly familiar! And the scheming Mister Sinister cooks up a deadly threat in his cloning vats that even the combined might of Spider-Man and the X-Men may be unable to stop!
