Rezdas are Aurum enemies in Kid Icarus: Uprising. They can't attack Pit unless he runs into them. They make an unbreakable force field that cancels Pit's attacks upon contact, but their allies' attacks go right through it. The shape of its force field is a square, unlike the breakable spherical force fields of other enemies that Pit has encountered throughout the game. Thus, Rezda force fields can be ignored, and Pit can attack Rezdas where they are placed—in the center of their own force field. It is recommended to attack Rezdas with ranged shots because melee attacks are somewhat useless as Rezdas tend to float slightly too high from melee range for most weapons.
These Aurum forces defend their allies by erecting shields that prevent everything but other Aurum and their shots from passing through. This defense exposes their cores, so a careful aim should be enough to take them out.
