MarvelComicshas a history that spans decades and consists of thousands of stories and characters that have changed dramatically over the years; with so much content, continuity is hard to keep in order. WhileMarveldoes not go the reboot route as often as its fellow comic book company, DC Comics, from time to time they do hand out a retcon or two.When things just get out of hand, or a particular character needs new life breathed into them, a retcon of their history, origin, and even original abilities is implemented.

The changes can vary depending on the writer involved and can work out a number of ways, some good and some bad. More often than not, these changes are for the better to bestow some much-needed clarity for fans or to progress a character without moving him ahead in time and space. Here are some Marvel Comics retcons that were for the best.

6The Green Door

For a long time, the Hulk archetype has been one of the most unique and somewhat confusing groups in Marvel Comics. Since Bruce Banner originally became the Hulk, several new individuals have appeared as Hulks, spawning an entire faction called the Gamma Corps.Jennifer Walters as She-Hulk, Betty Ross, and her father have both emerged as Red Hulks and, with numerous others, have all appeared on the battlefield and even died in battle.

However, once a Hulk, always a Hulk, as each who perished has returned to the world of the living with no memory of their absence. How the Hulks constantly reincarnate has been a long-time question that was recently answered inAvengers#684, which expanded on the Hulk’s constant cycle of life and death. When a Hulk dies, they go to their own afterlife where they must fight their way to the Green Door, which allows them to come back to life. This paired well with the new mystical powers of Gamma energy as the Incredible Hulk himself underwent several drastic changes in terms of his abilities and origin.

However, Jean’s first resurrection of many was revealed: the phoenix who died was, in fact, a copy created by the Phoenix Force itself. The real Jean Gray resurfaced five years later after being discovered by fishermen trapped in a psychic cocoon. Her resurgence continued Jean’s popularity and made her a mainstay on the team.

Wolverine’s healing factor is constantly at work, keeping the adamantium infection at bay and healing his countless battle wounds, including the extension of his claws. However, Wolverine’s claws were not always one of his mutations. Initially, they were planned to be a part of the gloves he wore, but this was quickly changed as the character became more fleshed out. This change made a big difference throughout the character’s future that defined him in the comics, especially afterMagneto ripped the unbreakable metalfrom his bones.
