Acclaimed TV veteran Allan Heinberg and superstar artist Jim Cheung's complete YOUNG AVENGERS collaborations - in a single Omnibus for the first time! When the original Avengers disband, costumed teens Patriot, Asgardian, Hulkling, Iron Lad, Hawkeye and Stature unite to fill the gap. Their first order of business: surviving the wrath of Kang the Conqueror! Second? Weathering the disapproval of the adult Avengers! But when their teammate Billy's magical powers spiral out of control, the Young Avengers set out to find the one person who might help: the Scarlet Witch, who might be Billy's mother…and whose own uncontrollable powers caused the Avengers' dissolution! Once the young heroes find her, nothing will ever be the same!
