FF #6Number 8: Fantastic Four #6
"Captives of the Deadly Duo!"  (Marvel Comics, September 1962)

Sometimes I still can't believe that I have a copy of this issue in my collection.  This issue claims the title for the most money I have ever spent to purchase a single issue.  I bought my copy the morning of my wedding day after having read reprints of the issue (in various formats) many times over. 

This issue chronicles the first super-villain team-up in the history of the Marvel Universe, pairing the Sub-Mariner with Dr. Doom.  Dr. Doom talks Sub-Mariner into attacking the FF at the Baxter Building, but Subby is double-crossed by Doom.  Dr. Doom must then face the combined wrath of Sub-Mariner and the FF in a final battle in space.

The artist for this issue is none other than the incredible Jack Kirby.



Crisis #12
Number 7:  Crisis on Infinite Earths #12

"Final Crisis"  (DC Comics, March 1986)

This issue is the final installment of DC’s groundbreaking limited series.  This issue features the remaining heroes from the old Multiverse fighting side by side with the new heroes of the revamped DC universe as they do battle against the Anti-Monitor and his hordes of shadow demons. 

The great thing about the Crisis series was the massive scale of the story itself.  The ultimate goal of the series was to reconfigure the supposedly "confusing" continuity of DC’s parallel universes (known as the "Multiverse") and pare everything down to one simple universe with a unified continuity.  Hundreds of heroes and villains appear throughout the course of Crisis, some of whom vanish into oblivion while others survive — complete with  new origins or a unified continuity based on their counterparts in parallel universes.

"Final Crisis" is full of surprises, including a temporary alliance between Rip Hunter (and other heroes) with the super-villains Brainiac and Darkseid.   The final fate of the Flash (Barry Allen) is revealed to the heroes and other characters like Robin (Earth-2), The Dove, and many more meet untimely demises.  Other important moments in the book include the team-up of all of DC’s occult heroes (led by Dr. Occult and Earth-2’s Green Lantern) and the final battle between the Anti-Monitor and Superman of Earth-2.

Crisis on Infinite Earths remains my favorite comics series of all time.  Many characters and features from the plot of the series are currently being revisited in DC’s long awaited sequel, Infinite Crisis.
