The Cosmic Cube is a major plot device and character in the saga of Secret Empire. It was SHIELD's use of the fragments of a Cosmic Cube in Project Kobik that set everything into motion. Those fragments reformed and took on a human persona, the young girl who named herself Kobik. SHIELD used Kobik to create the suburban prison for supervillains called Plesant Hill, using Kobik's reality warping powers to rewrite each villain's personality. SHIELD was unaware that Kobik had already befriended the Red Skull. The Red Skull set a plan into motion to defeat his greatest enemy, Captain America, by corrupting him. Steve Rogers was an old man at the time, having been deprived of the super soldier serum that had previously coursed through his blood and made him into a peak human specimen. Kobik restored Rogers to peak physical form but rewrote his entire history so that, even as Captain America, Rogers was always a double agent for Hydra.
