One of the best things that superhero comics do are massive team-ups where all of your favorite superheroes get together to kick butt against some horrible force that is about to destroy everything. Both Marvel and DC have no trouble with creating these types of tales, but Marvel seems to have become addicted to them. These superteam-ups force readers to buy issues of so many titles to get the "complete" story and guarantee stronger sales for the whole franchise. Marvel pretty much does one of them every year lately. It is getting old ... not because the stories aren't interesting. It is just a really cheesy method to bring about sales.

"Secret Invasion" introduces a story that actually has its roots in some of the earliest issues of the Fantastic Four comics from the 1960s. The Skrull are a race of shapeshifting aliens that have repeatedly challenged Earth in the hopes of drestroying humanity in order to keep us from interfering with their need for total domination. Fortunately, the worlds superheroes have risen to the occasion to fend of their schemes.

Now, the Skrull are taking on the form and skills of these heroes in order to strike at them directly in order to try and remove them as a threat. In the process, they remove the ability to fully trust those you are working with. The problem is that Earth's heroes better figure something out or lose the planet to the enemy.
