Another great two part story with Sub-Mariner is in IRON MAN 120-121, a story that protrays Namor sympathetically, despite his general scorn for humans.

The IRON MAN run in 115-156, by Michelinie/Romita Jr./Layton is one of my favorite runs, that ran concurrent with the Claremont/Byrne/Austin X-MEN run. And IRON MAN was my favorite in that period, even over that great X-MEN run.

Among many other great runs in that era, such as Stern's DOCTOR STRANGE 46-73, Duffy/Gammill/Villamonte's POWER MAN IRON FIST 48-84, Mantlo/Hannigan's SPECTACULAR SPIDERMAN 60-72, Shooter/Perez and Michelinie/Byrne's AVENGERS 141-202, Moench/Sienkiwicz MOON KNIGHT 1-30, Moench/Day's MASTER OF KUNG FU 102-120, Mantlo/Golden and Mantlo/Broderick MICRONAUTS 1-12, qnd 19-36, EPIC ILLUSTRATED 1-34 and BIZARRE ADVENTURES 20-34, plus many others.
