These two issues feel like fill-ins. Certainly #34 is, because the artist isn’t Roth and it has nothing to do with Professor X being kidnapped. Instead, it features Mole Man and his ongoing adversary Tyrannus. It’s bland and forgettable. But Cyclops does karate on Mole Man. That’s cool. Plus, they encounter him via a new vehicle.
They’re searching for a dude named Tyrannus, who lives underground.
But they should be searching for Professor X, which they do in issue #35, when they meet (and of course fight) Spider-Man.
But still, the kidnapping of Professor X, which happened in #33, but it still feels like a sideshow to the main event. A spider-robot attacks X-mansion (sent by the Factor Three band that kidnapped Xavier), and Peter Parker is vacationing nearby so we get a Spider-Man/X-Men team-up.
But of course a fight first, where Spidey literally kicks Beast’s butt.
Seriously, though, who vacations in Westchester? Issue #35 also introduces Changeling–an extremely minor character.
Also, we see that Banshee is also looking for the good professor.
