Warning! This post contains SPOILERS for Spider-Man: Across the Spider-VerseWhile the fate of Micheal Keaton's Vulture in Morbius made zero sense at the time, Spider-Man: Across the Spider-Verse has finally explained what actually happened to Adrian Toomes. While a villain being transported to another universe wasn't all that strange after the events of Spider-Man: No Way Home, Vulture became this unique exception whose experience couldn't be explained the same way. However, it looks like Sony actually had a plan (or at least found a solid explanation to course-correct).
As seen in Morbius' post-credits scene of Morbius, it was implied that the events of No Way Home caused Keaton's Vulture to end up in another universe beyond the MCU. However, the explanations given in No Way Home involving the spell cast by Doctor Strange couldn't be used for Vulture. Instead, Across the Spider-Verse reveals a better explanation, solving a mystery that would have been a major plot hole had it been left unaddressed.
Vulture Moving To Morbius's Universe By Doctor Strange's Spell Never Made Sense
Following the events of Morbius starring Jared Leto, Adrian Toomes' Vulture was transported from his prison cell in the MCU to one in Sony's shared universe of villains. Due to the similar purple rift in the sky, it was implied that this was the result of the spells Doctor Strange cast in Spider-Man: No Way Home. While the first spell brought villains from other universes to the MCU, the second spell sent them back to their own realities. Seeing how Vulture is from the MCU, Doctor Strange inadvertently causing his multiverse jump to the Sony Universe didn't make sense.
Because Vulture knew Spider-Man's secret identity before Mysterio outed Peter Parker in Far From Home, it was theorized that this could have led to the magic misfiring, shunting Vulture to another reality rather than the one he's meant to be in. It's also possible that Strange knew even less about the multiversal spells he was casting than he let on, not knowing that Vulture and perhaps other villains would be randomly thrown across dimensions. However, both solutions are rather flimsy based on the established logic given in No Way Home.
Across the Spider-Verse's Multiverse Anomalies Explained
Thankfully, Spider-Man: Across the Spider-Verse provides the perfect explanation for the MCU's Vulture. According to Miguel O'Hara's Spider-Man 2099 (Oscar Isaac), multiversal tampering such as Kingpin's super collider and Doctor Strange's spells in No Way Home create holes in the stability of the multiverse itself. This results in beings becoming multiversal anomalies who get thrown into other realities at random. Sending those anomalies home is the mission of the Spider Society formed by 2099, as those anomalies have the potential to disrupt "canon events" which could unravel the stability of the multiverse itself.
As a result, it seem as though the reason behind MCU's Vulture getting sent to Sony's reality is less about Doctor Strange's spell and more about what the spells caused in the aftermath. Because of these holes in the multiverse, Toomes is likely one of these multiversal anomalies. However, it's yet to be explained why so many of these anomalies just so happen to be Spider-Man villains, though perhaps it's because of their place on the Great Web of Life and Destiny connecting all Spider-Man variants together across the multiverse.
Michael Keaton's Vulture Is A Multiverse Anomaly
Micheal Keaton's Vulture being a multiverse anomaly makes way more sense as opposed to Toomes being sent to the Sony Universe via Doctor Strange's spell in the MCU. Being a random casualty of multiverse tampering in general certainly helps explain his new status and reality. However, there are still some lingering questions about Vulture in the Sony Universe that have yet to be explained.
A big question is how Toomes was able to build a new Vulture suit in the Sony Universe when the original was made using alien Chitauri tech. Likewise, it's odd that Morbius would have an interest in ing Vulture seeing as how he currently has no inherent connection to Spider-Man. While those questions will hopefully be answered in the near future, it's good that Spider-Man: Across the Spider-Verse was able to explain the biggest point of confusion as to why the MCU's Vulture was set to the Sony Universe in the first place.
