The past issue of Captain Ms. Marvel #3 had a one page throwback featuring Captain Marvelous aka Ms. Marvel and "Mister Marvelous."
Now, I really have no idea what's going on here, but Wendell Vaughn Quasar fans know that he debuted as Marvel Man in Captain America #217. There's some chatter in the forum as some folks thought this might be Quasar.
I do like what Dave Williams had to say in that it might be a throw away hook up between Carol and Wendell.
And regarding Captain Marvelous, that's either some sort of Power Ranger or something from an Australian soap opera.
I don't know, so what's Kelly Sue Fraction trying to say here?
