The mutants are known to sometimes develop further abilities and appearances. In some instances, those changes are named Secondary Mutation. That page concerns both the referenced Secondary Mutation, named as it, and other further mutations, including those stated to be Secondary Mutations by fans without editorial or canonical confirmation.

Emma Frost and Beast's hands, after their Secondary Mutations

The Secondary Mutation[1][2][3][4][5][6][7][8][9][verification needed][10][11][12][13][14][15][16][17][18][19][20][21] (or "Second Mutation")[22] is a phenomenon in which an existing mutant gains additional powers, or a change in appearance.

Secondary mutation is noted as the appearance of new powers, or an increase in existing powers.

The phenomenon was quickly a subject of public knowledge, as during the first days of Kitty Pryde as an X-Man, Professor Xavier attended a conference on this topic at Johns Hopkins University in Baltimore.[21]

It was stated by Beast that the secondary mutations usually occurred in the twenties of the subjects.[4]

The Secondary Mutations generally appear in time of great stress.[10]

It has been shown that secondary mutation could be triggered by more or less natural means, like Beast's mutations coming from his initial experimentation on himself,[23] Elixir's triggered by healing himself (though it was suspected to not be a Secondary Mutation by Dani Moonstar),[4] Quentin Quire's by his overuse of Hypercortisone D,[8] or even created, as for Emma Frost's diamond body somehow " "created" " by Cassandra Nova.[13]

There is some beliefs and hinting points that the Secondary Mutation are linked to the mutants population state: Beast stated that his feline form was possibly linked to that year's mutant baby boom.[24]

However, since the Return of Hope Summers, Husk's powers were somehow jammed,[25][26] later diagnosticed by Beast as a Secondary Mutation.[16]

Confirmed and suspected Secondary Mutation subjects

As far as we know the first Secondary Mutation witnessed and stated as such is Emma Frost's diamond body, " "created" " somehow by Cassandra Nova.[13]

After the Stepford Cuckoos demonstrated the ability of flight, they were diagnosticed a Secondary Mutation by Kitty Pryde and Beast,[10] but regarding to the following events and the revelation of them Cuckoos' origin, that statement can be strongly contested as being in fact the doing of Phoenix.

Fan-stated and unreferenced Secondary Mutation subjects

Many occasions of further mutations has been shown, without the statements of Secondary Mutations.

The "first known subject" is Polaris.[27] Beast "is actually the second"[24] and it is he who named the phenomenon.[3] (Actually Beast "had his first (unnamed this way) secondary mutation years before"[23]).

If you have a reference for one of those mutants, feel free to add it and make the changes.
