Fantastic Four 186

FF #186 from Sept. 1977.  "Enter: Salem's Seven" by Len Wein and George Perez.

Let's take a moment to enjoy some violence against the Impossible Man.

Fantastic Four 185

FF #185 from Aug. 1977.  "Here there be Witches" by Len Wein and George Perez.

Impossible Man's life and my childhood...pretty much identical.

Fantastic Four 184

FF #184 from July 1977.  "Aftermath: The Eliminator"

Tigra and Thundra don't exactly part on the best of terms.   Nothing seems to come of this so-called "war" either.

Fantastic Four 183

FF #183 from June 1977.  "Battleground: The Baxter Building" by Jim Shooter, Len Wein, Roger Slifer, Roger Stern, Ralph Macchio, Bill Mantlo and Sal Buscema.

Thundra throws around Impossible Man.

Fantastic Four 182

FF 182 from May 1977.  "Enter: The Mad Thinker" by Bill Mantlo, Jim Shooter, Len Wein, Archie Goodwin and Sal Buscema.

Evil Reed sends the Terrible Trio on their own mission.   Nothing comes of it.

Fantastic Four 181

FF #181 from April 1977.  "Side by Side with Annihilus" by Roy Thomas and Ron Wilson.

Annilhus is scared of a guy in his underwear and a little fire.  What a wimp.

Fantastic Four 180

Despite the cover...

..this story does not feature Thundra, Tigra or Impossible Man.   Just imagine the disappointment of the readers of 1977.  Who found a reprint of FF 101 instead.
It does feature the first (and only) appearance of the Top Man.  I'm guessing the readers of 1977 were just begging to see the Top Man.
