Tipped off that the Avengers have been abducted by Kang, Hawkeye rushes to the Avengers Mansion, to be met by the Swordsman and Rama-Tut.
It seems Rama-Tut's a later version of Kang who, tired of endless conflict, returned to Ancient Egypt to reclaim his throne before deciding to prevent his former self from acquiring the Celestial Madonna. For that end, he had himself sealed in his tomb, in a state of suspended animation, until the time was right for him to awaken.
The trio set off to stop Kang's attempts to start World War Three but first have to defeat Kang's Macrobots, each of which contains and is powered by a paralysed Avenger.
Mantis who's destined to be the Celestial Madonna.
The villain decides that if he can't have her, no one can and tries to kill her but the Swordsman flings himself at the shot and, as Rama-Tut and Kang vanish, fighting, the Avengers are left to ruminate on the death of their fallen colleague.
Hooray! Hawkeye's back! He may be the second-least powerful member the Avengers have ever had - and not always have the best of attitudes - but, like Hank Pym, he's always felt like one of the things that makes the Avengers the Avengers. Although I suppose the fact that he returns in an issue whose cover promises us the death of an Avenger tips us off as to who that Avenger'll be. Let's face it, they're not going to bring Hawkeye back as the natural replacement for Thor, Iron Man or the Vision.
That means it can only be the Swordsman who cops it and, at last, the poor sucker gets to be the hero he's dreamed of being. And finally, after spending chunks of the issue insulting him, Mantis comes to appreciate him.
PS. Does anyone know if Neal Adams had a hand in the inking? Dave Cockrum gets sole art credit in the issue but there're certain panels where the inks have a noticeably Neal Adams vibe to them, not least in the last three panels and also the full-page splash where the Avengers combine to attack the Thor-powered Macrobot.
