Introduction

And there came a day, a day unlike any other, when Earth’s mightiest heroes and heroines found themselves united against a common threat. On that day, the Avengers were born—to fight the foes no single super hero could withstand! Through the years, their roster has prospered, changing many times, but their glory has never been denied! Heed the call, then—for now, the Avengers Assemble!

Countless dangers threaten Earth and her people: would-be world conquerors; powered armor-wearing madmen; invaders from outer space and other dimensions; ruthless assassins; criminal and terrorist organizations bent on world domination; mad scientists equipped with super-technology; evil sorcerers and their mystic minions; and costumed criminals of every possible description.

Fortunately, an equally diverse array of superheroes stands ready to oppose these menaces at every turn and keep humanity safe.

You are one such hero, ready to put your life on the line to defend Freedom, Truth, and Justice. Sometimes you struggle to balance your personal life and responsibilities with the undeniably important duties of your costumed persona, but in the end all the effort’s worth it… usually.
Over the past two decades, the Earth has been through momentous changes that have shattered humanity’s preconceptions and beliefs. Extra-terrestrial life exists; magic is real; other dimensions, while unseen, are infinite in number. It has been the job of all superheroes, especially the Avengers, to maintain peace and defend the Earth from all threats.

But now, there is movement in the shadows. Unknown forces are at work attempting to bring about change according to their secret agenda. Their influence extends to every part of the globe, and their agents have infiltrated every major organization.

The Avengers have never faced an enemy this well-entrenched. How can they protect the Earth from its enemies when they don’t know who is an enemy and who is a friend?
