Strengths and Weakness
This fruit has an odd strength, the user will produce a certain wave of light that hasn't been yet discovered by scientist. In doing this, this light affects different people and their perception of the user. Thus why it is called the Mary-Mary fruit, because of how the user would see them.

Such examples as, the user can give off this "light" and as the wave lengths go through the eyes and into the brain. It can create illusions by which the user can manipulate, so this is fruit is one of the rare devil fruits that don't have much purpose for either defense or offense.
