The Avengers Omnibus – Vol 04 by Thomas & Engelhart

The merciless Kree and the shape-changing Skrulls have gone to war and humanity is on the front line. It’s Roy Thomas and Neal Adams’ classic Kree-Skrull War! Then, every Avenger from day one returns – to battle Ares and the Enchantress! And there’s no time wasted upping the ante when the mutant-hunting Sentinels return from the heart of the sun. Next, enter: Steve Englehart! The Avengers’ new writer doesn’t miss a beat as he builds up to Marvel’s first hero-vs.-hero epic – the Avengers-Defenders War! Also featuring Mantis’ first appearance, Vision and the Scarlet Witch’s growing romance and a battle with Magneto alongside the X-Men.
