Bill Murray’s character has already been confirmed in Marvel’s newest film, Ant-Man, and the Wasp: Quantumania. Along with it came confirmation that the Marvel Cinematic Universe (MCU) has made a major shift from the comics.
In the comics, both Lord Krylar and Jarella are associated with the Hulk; they lived within the subatomic realm called the Microverse, and the Hulk was trapped there for a while.
He fell in love with Princess Jarella, a woman who accepted both the Hulk and Bruce Banner personas, Lord Krylar was Jarella’s rival for the throne of the subatomic planet K’ai, and he died in his first appearance.
This confirms that Marvel has turned the Microverse into the Quantum Realm, merging another specific dimension from the comics, making them one thing in the MCU.
Ant-Man’s Quantum Realm may have been inspired by the Microverse, but at first, it seemed to have very different properties. Initial glimpses of the Quantum Realm suggested it was hostile to life, and it wasn’t until the Ant-Man and the Wasp sequel that it started to look like that wasn’t the case.
As Phase 3 continued, more of the Quantum Realm’s secrets were revealed, and it started to look like more of a dimension in the comics called Limbo. This is a plane of existence that every time traveler accesses as they move from one point in spacetime to another, and it is the traditional home of Kang the Conqueror. Now though, it’s becoming clear that the MCU’s Quantum Realm should be seen as a combination of Limbo and the Microverse.
This confirms what Dr. Spiros Michalakis, a quantum physicist who consults with Marvel, admitted as much in a blog post in 2015. He recalls receiving an email from Brad Winderbaum of Marvel Studios, co-producer of the first Ant-Man film, asking whether he could find an alternative to the Microverse name because of the legal baggage involved (the term doesn’t belong to Marvel). “I suggested ‘nano’, ‘quantum’, ‘atomic’, or… ‘quantum realm,’” recalled Michalakis.
Ant-Man and the Wasp: Quantumania (Ant-Man 3) will hit theaters on February 16.
