The Infinity Gauntlet. An ageless weapon of immense, maybe incalculable power. Once worn, its owner essentially becomes a god. They control the elemental forces of space, time, reality, mind, soul, and power. One Infinity Gem wields unlimited energy. All six combined cannot be stopped by anything or anyone in the known universe.
In the year 2014, a single comic book selling 300,000 copies in a single month is a very big deal. For perspective, the top comic from March was Batman #29, which sold just about 117,000 copies. April's top seller was Amazing Spider-Man #1, which managed a jaw-dropping 532,000, but was bolstered by numerous retailer incentives tied to variant covers.
The first issue of Skottie Young's new Rocket Raccoon series is a bit of an anomaly, though. Yes, it has reportedly sold 300,000 copies according to Marvel Editor-in-Chief Axel Alonso, and without much in the way of arcane retailer incentives, but it seems that about 100,000 of those comics were all ordered by one source: Loot Crate, a service that sends subscribers monthly boxes of "geek and gamer" merchandise.
