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-favourite 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!
