They just don’t make them like this anymore. The Champions was a short lived (17 issues) series from Marvel Comics that was published from 1975 to 1978. It featured the most unlikely team you would ever imagine (Hercules, Ghost Rider, Black Widow, Iceman, and Angel).
The group was formed when the U.C.L.A. campus was attacked by the Greek God Pluto and his allies Ares and Hippolyta. It’s seems that Iceman and Angel (of the X-Men) were attending UCLA. Ghost Rider just happened to be in town. Hercules was giving a guest lecture in Mythology on campus (I don’t make this stuff up) and Black Widow was applying for a job to teach children how to speak Russian.
They’ve attacked UCLA campus to capture Hercules and force him to marry Hippolyta (Queen of the Amazons) and Pluto intends to marry the goddess Venus, who just happened to be in LA as well. The group bands together at the end of issue #1 and plans to stop Pluto and his plan.
