Miles Morales is unique as one of the two survivors of the original Ultimate Universe. This makes him a figure of interest to the other survivor, a villainous Reed Richards variant known as The Maker, A new teaser confirms the two are destined to interact again in the upcoming Ultimate Spider-Man: Incursion miniseries.

Written by Deniz Camp and Cody Ziglar, with art by Jonas Scharf, Ultimate Spider-Man: Incursion will center around Miles Morales. The early press revealed that Miles would be drawn into the new Ultimate Universe, chasing after his baby sister. However, it now appears that this chain of events is the work of The Maker and is tied to a scheme to free himself. This, coupled with the title, suggests The Maker is intentionally trying to collide the new Ultimate Universe and Earth-616.

Ultimate Spider-Man Incursion explained
In the cosmology of Marvel Comics, an incursion occurs when two universes collide. This subsequently causes the boundaries between realities to erode. Sometimes, this results in one universe being absorbed into the other. Most times, however, it results in both universes dying.
Incursions figure prominently in the plot of Doctor Strange in the Multiverse of Madness. However, they first appeared in the comics building up to the 2015 Secret Wars event. There, incursions were used by the cosmic Beyonders as part of a plan to destroy the multiverse.
It is suspected the upcoming Avengers: Secret Wars movie will be adapting that storyline. Given that, it makes sense that Marvel might use Ultimate Spider-Man: Incursion to refresh the concept for current comic readers. In any case, Miles Morales will have his work cut out for him trying to save his sister and two worlds.
Ultimate Spider-Man: Incursion #1 arrives in comic shops everywhere on June 4, 2025.
