Reprint from TALES TO ASTONISH #16 (1961) in this issue. The story was originally titled "Here Comes Thorr, the Unbelievable", but for some mysterious reason was renamed "Thorg" (okay, not so mysterious). A 7-page Kirby/Ayers effort.
This is one of many examples of Kirby using large stone creatures (including, oddly , the first Thor story soon after this), specifically Easter Island types, in stories. I think there was an article in TJKC about it. Anyway, in this one Linus, an archaeologist, and his wife Helen go to a recently discovered remote volcanic island in the Pacific to examine some giant stone heads. He finds a hidden room and trips an electric eye, which brings one of the heads to life, digging itself out to reveal a giant figure. Turns out Thorg is part of an advance team for an alien invasion. Linus convinces Thorg that he can conquer Earth solo, without activating the other heads, and calling his people to the island. Naturally everyone else assumes that he's betraying humanity.
But after the other aliens arrive, Linus sneaks away and uses dynamite to trigger the volcano, destroying the island, knowing that the aliens rocky bodies would sink in the sea. Everyone else flees, but they return for Linus when they realize what his plan was. The natives don't seem too upset by him blowing up their island, but he did save humanity.
Lots of common plot points from several other stories, like man pretending to sign with the invaders and the advance force to the invading army, but as usual put together in a clever way, and great looking artwork. This story also features another of the "world balloons" often seen in stories of this era.
The cover is a modified version of the Kirby/Ditko TTA #16 cover, with various figures added, as well as some boats and water across the bottom.
