Review/plot:
Not sure if this was a rush issue or what. The credits don't distinguish between what Buscema and Kane did, but looking at the issue again it's pretty clear that Kane draws the first half of the issue and Buscema draws the second. The Unofficial Handbook of Marvel Creators also says that John Romita Sr. was given a belated art credit as well (in the lettercol for issue #20). As Jesse notes in the comments, Kane is later given a plot credit for this issue as well.

The art certainly isn't very good, and neither is the story.

It is a pretty important issue, though. Captain Marvel has his final showdown with Yon-Rogg and kills him. During the battle Carol Danvers is exposed to Kree radiation via Yon-Rogg's Psyche-Magnetron that will eventually turn her into Ms. Marvel.

You can see the shift from Kane art to Buscema.

And here's a nostril comparison. Kane's Rick Jones from the first half of the book...

...and Buscema's Captain Marvel from the second.

Also in this issue, Rick Jones meets the ridiculous Mordecai P. Boggs, who will become his agent in the music business (art is from Kane's first half).

Quality Rating: D+

Shouldn't we track the Psyche-Magnitron? It's pretty important in Operation Galactic Storm.

I don't have tags like the Characters Appearing for objects/artifacts, but i've listed the Psyche-Magnitron in the Historical Significance since you're right that it has multiple appearances.

The layouts (and the nostril shots) scream Kane as the primary artist. Maybe Buscema inked?

I don't have this issue so this is secondhand info, but according to the GCD, the pencils were split this way: Gil Kane, pp. 1-11; John Buscema, pp. 12-20.

Thanks guys. Was looking through the issue while Shar posted, and it's pretty clear to me now that Buscema takes over with the second half. I've reversed the credits and added some more Buscema shots.

The letter column in issue 19 mentions that Gil Kane plotted this issue along with writer, Roy Thomas.

I just saw this splash page in Sean Howe´s Tumblr today but i can´t place it. Could you guys tell me where does it come from?

It's part of the unpublished Starhawk story meant for an issue of Marvel Super-Heroes v.1.

Thanks, Omar. So, i take this "Mandroid" the title mentions never made it into the Marvel Universe? Was not therea Kree Mandroid?

There were 3 different Mandroids. There were the Mandroids in the unpublished Starhawk story (no relation to the Guardians of the Galaxy Starhawk), there was the Kree Mandroid in this story (it's the golden robot with the eye beams), and the Mandroids from Avengers 94-95, which were men in armor, not androids in any real sense. All three types of Mandroids are completely unrelated. Roy Thomas just came up with the term, and kept using it until it stuck. The Avengers Mandroids showed up again in X-Men 118 and have become recurring characters (sort of) in the Marvel universe. The Kree Mandroids showed up again in Kurt Busiek's Iron Man, but are otherwise forgotten.
