The Mighty Avengers Vol. 1 (2007-2010) #3

Plot

Nick Fury is back! As the war with the Skrulls reaches a fever pitch in SECRET INVASION, MIGHTY AVENGERS answers many of the event's most compelling questions: Where is Nick Fury, and what has he been up to? Who are the mysterious "Caterpillars"? What's keeping the Sentry from taking out the shape-changing aliens single-handedly? And Hank Pym's a Skrull... how the heck did that happen?! Featuring Fury, Sentry, Pym, Spider-Woman, the Wasp and the Avengers, these four stories excite and unnerve at the same time!

Collects MIGHTY AVENGERS #12-15.
