The Spider-Verse movies bring together different versions of Spider-Man from various media formats to celebrate the character’s history. In Across the Spider-Verse, the appearance of Insomniac’s Spider-Man helps explain why Miguel O’Hara believes Miles Morales’ dad must die, as he did in that particular version. The movie avoids directly referencing game plotlines and other versions of Miles Morales to focus on the franchise’s main character and preserve the impact of how special Miles is.
The Spider-Verse is now a multiverse, with multiple versions of Spider-Man existing across different media. Across the Spider-Verse showcases various Spider-Man variants and combines different animation styles. Insomniac’s Spider-Man, from the Insomniac Spider-Man game, makes a cameo appearance alongside other Spider-Man video game cameos, providing a deeper connection to Miguel O’Hara’s theory about Miles’ dad’s death. Miles’ father died in the game, so this version of Peter Parker supports Miguel’s belief that canon events cannot be changed.
Miles Morales becomes Spider-Man in Insomniac’s Spider-Man game, although his origin story differs from the Ultimate Comics or Into the Spider-Verse. Insomniac Peter Parker knows and is friends with Miles, whose father died in the line of duty. While this is just one instance of Miles’ dad dying, it strengthens Miguel O’Hara’s conviction that certain events are fixed in the Spider-Verse.
Despite the connection, Across the Spider-Verse does not acknowledge that Insomniac Peter Parker has fought alongside Miles Morales. The movie avoids focusing on versions of Spider-Man who should already know Miles Morales in their universe to keep the worldbuilding simple. The story of Across the Spider-Verse is centered around Miles Morales being special and an anomaly, as the spider that gave him powers came from another universe. Referencing other versions of Miles or a plotline from a game that not all viewers may be familiar with would complicate the narrative and potentially confuse audiences.
Overall, Across the Spider-Verse maintains its focus on Miles Morales as the main character and avoids referencing other versions of him. The exception is the revelation of Miles Morales from Earth 42 during the movie’s ending.
