It starts with Spider-Man and Nomad versus Taskmaster.
Everyone loves Taskmaster. Tasky is recruiting henchmen to serve a new villain named Black Abbot. It will take three issues to defeat Abbot.
He’s forcing scientists to work for him and manufacture a machine that enables Abbott to control peoples’ minds. Turns out, one of the scientists thinks Peter Parker would be a good addition to the team. So, Abbott tries to kidnap Peter and Human Torch comes along to help.
There were much better ways to have Spider-Man continue to be involved with Black Abbott following issue #146. This was pretty contrived. Similarly, Thor gets involved because Abbott commits a crime near the construction site he works at in his secret identity.
Also: Superman reference.
Twice.
