When two people fuse through the fusion dance, or the potara earrings, the newly fused product leans to the characteristics and personalities of the two former subjects, but they do not submit to their control. The only character who ever submitted to control was super Gogeta, who had no choice.
The pupil is a hole located in the centre of the iris of the eye that allows light to strike the retina. It appears black because light rays entering the pupil are either absorbed by the tissues inside the eye directly, or absorbed after diffuse reflections within the eye that mostly miss exiting the narrow pupil.
The pupil acts as an entry point for light to enter your eye. Surrounding muscles in the iris, called the pupillae, adjust the pupilâs size automatically depending on light conditions. In light conditions, your pupil will probably be around 3mm in diameter. In total darkness, this diameter can extend to over 6mm.
