You're in LUCK!!! So much luck!! Listen, after you finish reading Secret Invasion and his Avengers run during that time, go back and re-read everything from Avengers Disassembled on. There are hidden clues EVERYWHERE!!!! No one in comics has ever done anything like this to this level. It is his Masterpiece.
I'll give you some hints. They are not so SPOLIERY, they are just hints. Avengers Disassembled, during the battle scenes, there are Skrulls in the explosions for seemingly no reason. Wrong. They are purposefully planted there. The skrulls were behind the disassembly. It's part of the war tactics the Skrulls enacted, secretly infiltrating positions of power. Skrulls caused the Breakout. Skrulls caused the kerfluffle in the Savage Land and Japan. Skrulls were in the Civil War. (Hank Pym, issue #1 final page) And there's lots more to see.
More hints: Iron-Man in Disassembled mentioned how Ultron could inhabit new forms and technologies, creating a clusterphuck of a problem for the Avengers, which he later did in Mighty Avengers. Ultron appeared again in the Avengers first arc where they fight the Ultron of the future! Look at the battle scene, you will see the "Young Cyclops" that Bendis years later put in to his brilliant "All New X-Men." In the scene where they talk timelines, there's lots of X-Men and Secret Wars hints. In Age of Ultron, this is actually the 3rd/4th time the Avengers fought Ultron. Age of Ultron is his 1 epic finale. His other finale is Avengers Vs. X-Men, where removing Professor X was a brilliant move.
Hint: Read the Secret Invasion Directors Cut, issue #1 contains 8 extra pages.
Extra Reading: Civil War The Confession is the finale to Civil War and is critically rated as Bendis's best written comic. It's a must read. Illuminati #1 is the prelude to Civil War. There's an Avengers comic you may have read in the omnibus that was only available to US Soldiers where the Avengers fight the Kree. Read the Initiative after Civil War. Read the Illuminati mini series before Secret Invasion. Read Sentry, The Hood, Alias, Young Avengers, Daredevil for extra fun. Especially Sentry and Hood since they tie in HUGE. HUGE! Read Secret War by Bendis, its a fully painted book and ties in as well. House of M ties In.
See, when you consider all these books as 1 big run, it's clear that this is the ALL TIME BEST run on Avengers ever. (Of course, after Stan & Jack for establishing it) Don't let detractors fool you, they don't know shit.
Look me up on Facebook or YouTube, we'll talk more. Look up his bibliography on Wikipedia and try and read everything in order by date.
