Issue: Avengers # 11
Writer: Stan Lee
Artist: Don Heck
Publication Date: December 1964
Giant Man shows a little grumpiness about having to deal with his fellow Avengers. But then, Giant Man is always kind of a pain in this ass.
Kang monitors the Avengers from his headquarters (you know, in the year 3,000) and decides the best way to defeat them is to send a robot of Spider-Man to fight them. There's got to be some sort of super villain training camp where they can show aspiring do-badders the moves not to make when plotting against one's enemies. If there isn't, someone should start one. Hey, you'd stand to make a decent amount of money.
So the Avengers fight a Spider-Man robot, and then the real Spider-Man shows up to set things straight. The team figures out that Kang is behind all this villainy, but their next confrontation with Kang will have to wait for another issue.
Spidey on Spidey combat! Now I'm going to use exclamation points for all my sentences like Stan Lee! Huzzah!
