here’s a little headcanon I had about the Lake Trio’s powers, based on the myths we can read in the that tell us a bit about the trio (specifically “A Horrific Myth”)
The Lake Trio’s powers to take will/emotions/memory from people vary in severity by how much contact/time the victim spends under their control.
For example, a person who only spends a few seconds under a spell caused by Uxie would forget maybe a few things about their day, but wouldn’t be particularly affected. A person who is afflicted by Mesprit for a little while would feel varying degrees of “disconnection” from their emotions, or a hollow feeling for a few weeks to come. If someone is controlled by Azelf for a considerable amount of time (say, 15 minutes, a half hour, Heaven forbid longer) runs the risk of losing their will to move or live completely, and basically become a human shell who cannot function at all (no speaking, movement, reactions, but still breathing; alive, but not really there).
After coming in contact with the trio in any form, the victim blanks out, faints, or fall into a sleep-like trance. The time spent doing this also varying on how long they interact. If for a few seconds, the person/Pokemon may experience a quick loss of movement and seize up before coming to again, or fainting.
This also can worsen the affects for people with mental health problems. Azelf is particularly bad with people that have suicidal thoughts.
