To me, my X-Men!

Mutants

Human Mutants have many distinctive traits in regards to biology, physiology and genetics from other humans. Mutants can have wildly varying biologies depending on the nature of their mutation. Mutation is caused by the X-Gene in the mutants' DNA. Mutations normally manifest themselves during puberty, often as a result of a traumatic event. Some mutants exhibit their mutations at birth, however, while others do not manifest their powers until adulthood. Secondary Mutation is a phenomenon in which an existing mutant gains additional powers, or a change in their appearance due to a second mutation. The mutants can be divided into multiple categories, regarding to their origins, genetic status, powers (e.g. Omega Level Mutant), etc.
While in most Marvel universes the X-Gene was presumably a result of modifications on early man by the Celestials, in Earth-1610 the X-Gene is a creation of the US government weapons project in Canadian facilities. This reality's Wolverine was the first of these mutants, and was called the Mutant 0. This mutation is similar to a virus, infecting the population slowly and turning them into mutants.

• American Mutants: Mutants who are home in the United States of America.
• International Mutants: There are also mutants the world over, obviously. This is a sample of them, organized by their countries.
• Mutant Superheroes: Mutants who use their gifts for the greater good. Ar, at least, profit while doing the right thing and helping others.
• X-Men Members: The X-Men, Mutants who use their gifts to protect a world that fears and hates them, defenders of Professor X's Dream of Human and Mutant Coexistence.
  • Xavier Institute Student Body: Students of the Xavier Academy.
• Evil Mutants: Evil is a pejorative term, but these Mutants use their powers for Crime or Terrorism, or at least inflicting misery to others and enforcing their will.

Mutates

A mutate is a being who acquired a physical characteristic through exposure to one or more mutagenic agents such as chemicals or radiation. Superhumans who were not born with the potential to access their innate superhuman powers are mutates.
Mutates are typically characters that have been somehow genetically mutated in order to attain their superhuman abilities, for example by exposure to magic, radiation or toxic waste, through the bite of a genetically-engineered spider, et cetera.
Human mutates are sometimes called altered human or non-mutant variant.

• Note: Mutants that were given a Genoshan Mutate number, or used one to conceal their identity were called "Mutates".

Xavier Institute

This mansion, located at 1407 Graymalkin Lane in Salem Center, New York, had been inherited by Charles Xavier and has been in his family for a 100 years.

The saying of the Institute is 'Mutatis Mutandis', which is Latin meaning 'with those things having been changed which need to be changed'.

Located at 1407 Graymalkin Lane in Salem Center, New York, the Xavier Mansion has been home to the X-Men since their inception, and has always been a school and safe haven for any mutants in need. The mansion has been the subject of damage due to battles and has even been destroyed twice. Once during the events of Inferno, in which Mr. Sinister destroyed the whole mansion, except for its underlying basement (which included the X-Men training-ground; the Danger Room). After some time the mansion was rebuild with funds from investors in Xavier's school.

The mansion was later badly damaged during an attack by a former instructor, the mutant known as Xorn, who was posing as Magneto. The end of the battle left long time X-Man Jean Grey dead at the hands of the mad mutant. The mansion got a large renovation after these events, in which almost nothing of the original school could be rebuilt. The school was now in the shape of a giant "X". In the middle, there was a courtyard, where mutants could pay respects to the deceased Jean Grey.

X-Men

The X-Men are a team created by Professor Charles Xavier as a response to the emergence of naturally occurring super-humans known as mutants among the baseline human society. Seeking to promote his dream of peaceful coexistence between mutants and humans, Xavier trained his X-Men in the use of their powers at the Xavier's School for Gifted Youngsters, training them to become defenders of a world that hates and fears them. Over the years, the heroes of mutantkind found their mission constantly endangered by both reactionary humans and fanatic mutants.

Xavier Institute Student Body

Mutants could train their unique abilities in the a training-room known as the Danger Room. There also resides other high-tech equipment such as Cerebro, a mutant tracking device utilized by telepaths like Professor X. This device is in a highly-secured room and is available for only select few people such as Charles Xavier and the Stepford Cuckoos

X-Men Antagonists

Mutants in general, and the X-Men in particular, face a different type of enemy than other metahumans. First of all, the primary enemy of the X-Men is not a greedy plunderer, or an insane tyrant, or an omnicidal alien. The true enemy of the X-Men is Hatred. Hate and Fear of the unknown, the different.. the mutant. Protecting mutants from persecution and misunderstandings, and protecting humanity from the depredations of Evil Mutants, the X-Men stand united against this one pervasive adversary.
More interestingly, the X-Men and most of their rivals tend to share cultural and genetic origins. The Brotherhood of Mutants, the Mutant Liberation Front, and several other people whom the X-Men have clashed over for noble reasons over time, have time and time again sided with the X-Men when the threat came for their race as a whole. Sentinels. Friends of Humanity. The Phalanx. The one unifying tread all mutants have, their need to survive past being the subjects of hate or convenient scapegoating.
As such, very few 'Evil Mutants' actually exist that have not, at one point, sided with the X-Men against their shared common enemy. This is why over time, practically everyone of the X-Men's enemies have worn an X somewhere on their costume, or have been otherwise associated to the Xavier Institute.

• Evil Mutants: The most common enemy of the X-Men are those Mutants who seek profit, or power, or terrorize humanity, making the X-Men's Dream of peaceful coexistence a harder goal to achieve. There are many of these, over a lot of time, with conflicting goals and motivations. Not every "evil Mutant" shares the same goal. Many are enemies to other Mutants, even other "evil" mutants. Several Mutants were also one-time enemy of the X-Men, and are located in another area, due to fighting only over a disagreement. Regardless, the X-Men oppose these Mutants, and are often the only reason some of these have not taken over the world, or committed a genocide.
• X-Men Other Enemies: While somewhat generic, these so-called "Other Enemies" are opponents of the X-Men, from all other walks of life. Greed, hate and fear, lust for power or control.. some of these are even, by all accounts, mutants, but operate under a larger group, following orders. This section also includes aliens, from space or other dimensions as well.
  

The World at Large

The World of the X-Men, also known as Earth-616, has many other superheroes, and other races, similar to, or offshoots of Mutantkind, or Humanity. While it is generally comparable to the real world everyone reading this is familiar with, massive leaps in technological advances have been made, by Mutants and Humans of note. Living Islands, quaint European hamlets doubling as World Superpowers, an isolationist African nation which gave the cure to Cancer.. it is not simply 'our' world but with Mutants in it. However, by and large, it is. Most of this world does not affect the situation or plight of Mutants, and as such, the X-Men interact with it peripherally. There are, however, things that affect their existence.

• New York City: The largest city near the X-Men's main location at the Xavier academy. The largest city in the United States, and due to the number of superheroes present there, the location for many major events, due to the idea of added multi-layered security. It is also the only location, since the Genoshan Massacre, to have a central mutant city-wide hub.
• Government Agencies: The governments of the world have to take Mutants into account. For good or ill, countermeasures to Mutant terrorists have to be prepared. Threats, both from within and without, must be accounted for, by individual countries, as well as by the world community. These groups will just as often work alongside the X-Men as they will butt heads with them. Whatever the situation, no expectations should be held.
