Template:Infobox comics location Microverses are dimensions occurring within the fictional Marvel Universe. The Microverses are often visited by the Fantastic Four in various adventures. They were formerly defined as any universe only accessible through vibrational attunement (shrinking).[citation needed] The belief that these worlds exist within atoms may have given rise to the stock phrase "There are worlds within worlds". It is not actually the microverses that are microscopic in size but rather the nexuses which make them accessible. It is thus theoretically possible to enter the same microverse from different points on Earth. The volume of these microverses are contained within spacewalls which can only be breached at certain points. It is these breaches that create accessible portals.
Originally, many microverses existed within the Marvel Multiverse. The most commonly visited is the one containing the regions known as Sub-Atomica and the Micronauts Homeworld. This Microverse was populated to a large extent by a group of refugee starfarers from a doomed planet, Ithaka. Led by their leader, Wayfinder, they eventually settled on Earth.[volume & issue needed] They were displaced, yet again, by demons. With the help of The Sword in The Star, they were relocated to one of the Microverses.[volume & issue needed] They eventually became the ancestors of many of the races located there. The first multiverse visited by the Fantastic Four was one which Doctor Doom had actually been sent to. This one was like a Medieval Kingdom and Doctor Doom succeeded in taking it over after shrinking down the King and Princess Pearla, until the FF shrunk down and defeated him. It is shown that there are other worlds in this Universe including Tok, which has higher gravity and is inhabitated by Lizard Men.
These multiple microverses no longer exist. It was revealed during Peter David's Captain Marvel series that a thus far unseen conflict between Baron Karza and Thanos had resulted in all of the realms of the Microverse becoming merged into a single dimension referred to as the Microverse.[volume & issue needed]
Other inhabitants of the new merged Microverse include the Children of the Confluence of Stars and the Psycho-Man, a scientist exiled from Sub-Atomica. Psycho-Man was a recurring enemy of the Fantastic Four. This Microverse is also the "birthplace" of the Enigma Force which regularly manifests itself on Earth in the form of Captain Universe.
While on Earth, Wayfinder and his followers probably settled in what is now India. Several of his leading followers had names such as Agni, Yama, Mara, and Kali which are names out of Hindu mythology. Their presence may have inspired these myths and Dr. Strange did acquire an ancient monolith that was found in India that bore images of the Cosmic Keys that would become instrumental in saving the Microverse.[volume & issue needed] Additionally, the Micronese language (of the Micronauts' Homeweorld) bears slight resemblance to Sanskrit.[citation needed]
In the mini-series Realm of Kings: Son of Hulk, Hiro-Kala and his entourage journey into the Microverse where he landed on K'ai.[1]
