The Reflector Sphere is 2 thin metal plates that orbit a specific bloon that it has been randomly assigned to, upon contact with these plates most projectiles bounce off and continue with their path in that direction, still capable of hitting and dealing damage to other bloons/blimps. On the other hand, certain explosives will explode and deal damage to the actual bloon. And if a shot gets in between the plates it will hit the bloon as normal, and larger bloons will have larger gaps as the sphere stays the same size at all times.
