Below is a list of known Alternate Realities that the Exiles have traversed through over the course of the series. They are listed in the same order in which they were first appeared in their adventures, with the exception of 616 which will be reserved for the Normal Marvel Universe. This could give you a few ideas to run an Exiles' adventure.
Zero Tolerance
The world has Zero Tolerance for Homo Superior and Super Beings. There are no X-Men, no Fantastic Four, no Avengers... They have all been jailed, executed, or aborted as per the policy enacted 50 years ago.
Dark Phoenix Saga
Jean Grey becomes the Phoenix Force in this reality and changes into the Dark Phoenix. In our reality, the Phoenix Force impersonated Jean.
Wolverine's Alpha Flight
On this world, Wolverine never joined the X-Men and instead remained in Canada to lead Alpha Flight. When the Hulk entered Canada, he became Canada's problem and Canada's problems are Alpha Flight's problems. This paved way for Project Goliath, a mission headed by our Favorite Fur Ball for the capture of the Green Menace.
Skrull Gladiators
After a major shift in the Skull-Kree War, the Skrull Empire decided to set up an outpost on Earth just before the Industrial Revolution. Humanity was less than helpless. The Skrulls leveled the planet to make room for military outposts that were converted into Skrull colonies. Though the tide of the great Skrull-Kree War eventually turned again and Earth's military usefulness became outdated, the Skrulls remained on Earth for the mild climate, good agriculture, and continued to rule over and oppress the weak inhabitants.
Mutant Registration Act
It's a world that has been long at war. Years ago, the Mutant Registration Act was passed and the creation of an army of giant mechanical warriors was green-lit. The Sentinels were born. At first, mutant all over the globe were imprisoned or massacred. Then, all beings with greater powers were targeted. It went on for years. New alliences were created as the war stretched on and on, but it became hopeless. Eventually, any and all people with even the remotest genetic indicator of possible mutant or advanced-human ability were removed from society to ensure what was percieved as safety.
Atlantis/Latveria War
The city of Atlantis and its inhabitants were the victims of natural disasters and interloping nations. It hardened them into a warrior race. No longer will they wait to be the prey of surface dwellers. They plan to conquer it and the small European country known as Latveria will be the first to fall.
Attack of the Lizards
When Dr. Curtis Connors lost his arm to a war wound, he focuses his studies on understanding the regenerative properties that reptiles possess in order to tap into that process and make himself whole again. He succeeded, but his celebration was short-lived as the mutagenic qualities of the serum he created also transformed him into a human-like lizard. For reasons unknown to us, either out of maliciousness or loneliness, the Lizard transformed his wife into a creature like himself. They then infected the entire neighborhood. Ten years later, the entire West Coast of the continental United States was overrun by the Lizards. The only solution was containment and so they built The Wall.
Vi-Locks
In an effort to save Cypher who has contracted the Legacy Virus, the sentient, alien computer called Warlock bonds to his friend creating an unexpected effect. The virus evolved. It made all those infected into something else, something evil. They grew into a race, one intent on becoming the dominant species on the planet. They are the Vi-Locks and they control Earth.
Heroes for Hire
Because nearly every major super-human on Earth is employed by Heroes For Hire, Inc., no one is willing to lend a helping hand to Japan when it is threatened by Moses Magnum unless some compensation is granted.
The Vampire Avengers
Captain America, the Vampire King, and his band of damned Vampire Avengers are well on their way to making over a million people into their mindless minions.
