Diamond: It looks as if it is always crying. It is actually adjusting its body’s fluid levels by eliminating excess.

Pearl +2: It prefers arid environments. It leaks water from its eyes to adjust its body’s fluid levels.

Platinum +6: It prefers an arid atmosphere. It leaks water that looks like tears when adjusting its moisture level.

HeartGold / SoulSilver: In order to adjust the level of fluids in its body, it exudes water from its eyes. This makes it appear to be crying.

Sun: It does not deal well with water, so it lives in dry locales. Since its surroundings tend to lack greenery, it stands out noticeably.

Moon: From its eyes, it can expel excess moisture from its body. This liquid is similar in composition to human sweat.

Ultra Sun: It discharges moisture from its eyes, making it look like it’s crying—apparently an effective way of getting enemies to let down their guard.

Ultra Moon: If its body gets too damp, it will die. So, in a process reminiscent of sweating, its eyes expel moisture.

Sword: It expels both sweat and tears from its eyes. The sweat is a little salty, while the tears have a slight bitterness.

Shield: This Pokémon lives in dry, rocky areas. As its green spheres dry out, their dull luster increases.

Legends: Arceus: Its tears elicit sympathy from those who see them, but do not be deceived! This expulsion of body water is merely a physiological mechanism for keeping itself in good health.
