Star Brand
Essentially the Star Brand is a zero-point energy collector, drawing power from the fabric of space-time itself. It is unlimited in potential, though the upper limits of the star-like tattoo of power are determined by the imagination of its wielder. A paradox, the Star Brand came into being when the universe was compressed into a single point of space for a mere microsecond. It has been wielded by several people in various realities.
Stark Satellite (Satellite Armor)
After the events of the "Civil War", Tony Stark became the director of S.H.I.E.L.D.. To protect planet Earth from an attack that Earth's heroes won't be able to deal with, so he designed and built a secret satellite station that is also an armor in order to protect the earth. The satellite armor is so secret that even shield doesn't know it exists.
Starwheel
The Starwheel was a massive device with large red tentacles and the capability of sending out red force bubbles that the tentacles attached to. The bubbles could turn transparent and engulf over its target before turning solid. The Starwheel would then absorb the attacks, whether mystical, cosmic, or physical, and turn it against the captive.
