They are the children of the atom¸ the next step in human evolution. They are mutants¸ hated and feared by mere humans. Some¸ like the X-Men and the New Mutants¸ are protectors of humanity. Others¸ such as the Hellfire Club and the Brotherhood of Evil Mutants¸ want to be the masters of humanity. Now¸ the major Marvel mutants¸ well-meaning and malign¸ are collected in one book. More than 50 heroes¸ villains¸ and interested parties are described inside¸ along with notes on the X-Mens mansion¸ important non-mutants¸ and the fearsome Sentinels -- mutant-hunting robots created by the United States government to deal with the mutant menace.
