Marvel Team-Up #89-90, Amazing Spider-Man #203

Marvel Team-Up #89, Spidey & Nightcrawler At The Circus: Nightcrawler and Amanda Sefton find out that a guy named Jardine is trying to stiff Arcade and back out on a deal to kill Spider-Man because he is going to do it himself. Jardine is some asshole Circus guy, and Nightcrawler knew him from his circus days. He goes to the circus to warn Spider-Man, there is a big fight where they fight against the assassin Cutthroat. There is a big fight and the heroes capture both Cutthroat and Jardine (with a little help from Arcade)

Marvel Team-Up #90, New York vs Television: Spidey and Beast team up to fight Killer Shrike and the Modular Man. Modular Man is going to use some weird device from a science exhibition in combination with the new broadcast TV power to supercharge himself. Spidey and Beast stop him by using the knocked out Killer Shrike's lightning powers to disrupt it.

Amazing Spider-Man #203, Trying To Make Dazzler A Thing: Some villain named Lightmaster is trying to use Dazzler to come back from some weird "Light Dimension" or something like that. Spidey and Dazzler team up to stop him from doing it. Yeah, I feel like I didn't have nearly enough context to understand this one.

X-Tra Notes: Some more throwaway crossovers. Team-Up #89 is the best of them, just because Nightcrawler and Spidey together is always fun.
