Project: Wideawake (MHAC5), softback supplement for Marvel Super Heroes, by Jeff Grubb
“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-Men’s mansion, important non-mutants, and the fearsome Sentinels — mutant-hunting robots created by the United States government to deal with the mutant menace.”
