Iron Man "Igor" suit from Iron Man 3

Large mechanized full-body suit of armor and weaponry that is able to be launched out of spit-tubes on spaceships in orbit around a planet.  When launched through atmosphere, the starShells are covered by a layer of friction armor which burns away during entry from heat generated between the armor and air molecules.  Landing is achieved with gravBoots that are part of the armor.  StarShells are generally used during an Iron Rain (and are where the Iron Rain gets its name from - a figurative rain of soldiers in suits of "iron").  They are incredibly strong - able to withstand attacks from most weapons short of railguns and razors.  They're also incredibly heavy, without the battery packs contained within (or if an EMP disables the electronics) the occupant would be unable to move.
