Marvel Two-in-One #26-33
In order, it's the Thing teaming-up with Nick Fury, Deathlok, Sub-Mariner, Shang Chi, Spider-Woman, "Mystery Menace", Invisible Girl and Modred the Mystic.
It all starts when Mentallo and the Fixer bring Deathlok to the present and brainwash him with plans to assassinate President Jimmy Carter (in one of his many Marvel appearances). After that's resolved (note: Carter didn't get killed), the Thing is sent to England to get Deathlok repaired. On the flight over, he and Alicia Masters run into the Sub-Mariner for a quick fight with Piranha.
Once in England, Thing runs into a plot with Hydra to abduct the doctor who can fix Deathlok. Shang Chi makes this appearance, but then it's a whole lot of Spider-Woman for the next few issues (from 29 through 33). This was probably only her second real appearance and she still has the full hooded costume. Her connections with Hydra are played up, as they turn Alicia into a super-spider. Sue Richards arrives to help and it's finally resolved.
Issue 33 is the final "Thing in England" story, as he and Alicia do some sight-seeing at Stonehenge. Spider-Woman follows because...uhhh. Modred pops up in a VERY heavily worded story about three elemental demons.
This was an attempt to make the team-up format into actual story arcs with a flow and not just "one and done" issues. It's a very meandering plot, but fulfilled the wishes of 70's fanboys to have SOME connection. The real problem is the scripting, as the Thing makes several pop culture analogies that don't flow into the situation and REALLY run on. Like: "you look like one'a them Bruce Lee types from those Kung Fu movies that Torchie tried to get me to see a few years ago. I had enough of that kind of action with Iron Fist".
The Thing whines a lot about his appearance and how Alicia's "the best gal in the world", but he's glad she can't see him. His "woe is me" attitude gets tiresome, as it's brought up at least twice per issue.
Art-wise, it gets pretty terrible, especially in issue 33. There are so many word balloons, that we just see profile shots of most characters.
The last stinky point is the "British" dialogue. Lots of "'ello" and "ruddy" type of stuff. Several British bobbies make analogies to WWII, which seems dated even by 1970's standards.
The Fury/Deathlok/Carter story is vintage Bronze Age Marvel fun, but the rest is junk. Spider-Woman (whose origin hadn't been determined yet) is the only mildly interesting thing in the mix. You have to wonder if someone was throwing darts and dared a writer to connect all these characters in a loose story arc.
