The Ultimate Universe's first-ever event series! Universes collide -- with Miles Morales caught in the middle! Before the Maker remade Earth-6160, he left Miles Morales the key to reach his new universe -- but when Miles' baby sister, Billie, uses that key to travel to the Ultimate Universe, it's up to Spider-Man to save her! The problem is that the Ultimate Universe is never safe for any Spider-Man! And when the Spot attacks, Miles meets an all-new Peter Parker -- and that's just the start of his journey across Earth-6160! Next, he teams up with fan-favorite ULTIMATES team members Giant-Man and the Wasp -- but the Black Panther isn't happy about these terrorist interlopers in Wakanda! Two of today's most exciting writers, Deniz Camp (ULTIMATES) and Cody Ziglar (MILES MORALES: SPIDER-MAN) join forces with rising-star artist Jonas Scharf (ULTIMATE UNIVERSE: ONE YEAR IN) for an adventure that will change Miles Morales -- and the Ultimate Universe -- forever!
