DC Special resumes with issue 16 (Spring 1975), continuing the numbering from the earlier series. The first issue, which contains all reprints, is given the theme of Super-Heroes Battle Super-Gorillas, and has reprints of Superman vs Titano, and Flash vs Grodd, as well stories of Batman and Wonder Woman fighting gorillas.
This pattern, of collecting reprints of different heroes under a larger theme, would run through many issues of the revival. Issue 18 (Oct/Nov 75) had Earth Shaking Stories, with reprints of Superman, Captain Marvel, and Flash and Green Lantern teaming up against Major Disaster.
DC Special 19 (Dec/Jan 75/76) was given War Against the Giants as a theme, and had Superman, Wonder Woman and Green Lantern reprints, as well as a story from Strange Adventures.
The last of these appeared in DC Special 21 (April/May 1976), with Super-Heroes War Against the Monsters, and included reprints of Superman, Green Lantern, the Marvel Family and the War That Time Forgot.
On a side note, the Super-Heroes Battle Super-Gorillas issue was clearly a success, as a one-shot reprint collection with that title was released for Winter 1976. Unlike the other books I mentioned in this entry, I actually owned this one. It featured Superman with King Krypton and Flash taking on Grodd, but the story I really loved was the Batman one, the Gorilla Boss of Gotham City, from 1953.
