Josh, Ron, and Conor are back to the Vault, but with a twist! This week, it's all about those famous and classic stories that make up the keystones of the Marvel Universe.

Before Secret Invasion, there was the Kree-Skrull War. Does this story from 1972 hold up? Is it related to the current drama happening at Marvel? Ron's read it, and he'll let you know.

Conor had to borrow a copy of Elektra: Assassin to take part in the show, and it certainly gave him something to think about. Is the combination of Frank Miller and Bill Sienkiewicz genius or madness? Perhaps it's a bit of both.

Finally, a glove of powerful gems will rule them all, and the Marvel Universe had better stop Thanos before he really messes things up. Did Jim Starlin tell a story for the ages, or is it best to leave The Infinity Gauntlet in 1991?

So true believers, step into the Vault with iFanboy, and check out these essential Marvel yarns.
