Making its first appearance at the end of the "Believe" arc, the Space Armor MK III was designed by Stark to enable him to travel into outer space. The suit sports back-mounted rocket thrusters and a redesigned helmet, which looks different from the faceplates featured on the previous armors, though the thrusters were gone by the second issue in which it appeared. The new armor - which caused Veritina, a member of the extraterrestrial race the Voldi, to refer to Stark as "Space Knight" - also contains an A.I. named P.E.P.P.E.R., which is modeled after Pepper Potts. The armor has advanced propulsion options, being capable of inter-atmosphere travel at Mach 10, or warp speed travel for outer space which translates to about "one trillion times" the speed of light.
