Mighty Avengers #28 (2007)

Guest-starring the YOUNG AVENGERS!
When the adults are away, it's the perfect time for VISION and STATURE to sneak a few friends into the Avengers new headquarters and throw a party. No, not that kind of party. It's a hunting party-- and the target they're after is...THE SCARLET WITCH!
Also: QUICKSILVER and US AGENT face off against a longtime Avengers villain and their new team. All this and the start of a strange cosmic odyssey for HANK PYM.
