Very little is known about Application Nine and most of his background is still kept in secret. His first appearance was in Soldier Zero #5 - Code Icarus, Part One in a hospital at Los Alamos, New Mexico. The purpose of his visit was focused on retrieving Solider Zero's exotech under Code Icarus, a procedure "The Company" takes in order to extract or recover alien technology from a particular place.
His character revolves around the fact he's an agent for "The Company" and that he's an specialist in alien technology, also claiming his suit is a reversal engineered model of exotech similar to Soldier Zero's, improved through a significant amount of patented proprietorial software.
"The Company" and its moral alignment is still a mystery but Application Nine made it pretty clear it is of very important for Soldier Zero to keep the Exotech off the government's hands and in the best of cases, to hand the technology to "The Company".
Application Nine features an advanced presentation of alien technology in the form of a suit which grants him super human physical attributes and defenses against very specific situations like suspended animation. Coupled with this, a multi-task device that grants him the ability to cast "apps" that allow him to bring force fields up, amplify his strength further, telekinesis, holograms, voice changers, technopathy, energy projection and constructs.
