A comic book
published by Marvel Comics
until the late 90s
. Originally, it stared the five original X-Men
pretending to be human
s specializing in the neutralization
of dangerous mutant
s. After a while, they dropped the mutant-hunter act and reveal
ed themselves as mutants themselves. They had helped save New York City
and were heroes
for a few years.
After a while, the five members rejoined the X-Men and the team name passed on to a new group -- Havok, Polaris, Multiple Man, Quicksilver, Wolfsbane, and Strong Guy -- who were employed by the United States Government to protect the nation and generally be poster boys for mutants everywhere. Peter David created and wrote this team for a few years, doing a spectacular job until he got fed up with the constant deluge of editorially-imposed crossovers and left the book. The title went downhill from there, finally passing into Marvel limbo while Havok was transported to an alternate universe as "Mutant X". The storywriting still hasn't improved.
