Mohn. The guy who handles the Poke Pelago.
I wonder if he is somehow related to Lusamine, Gladion and Lillie.
He's got the same hairstyle and color, especially to Gladion. Not sure about the eyes if it's blue or green though.
I agree and his eyes are green. Maybe it may confirm Lusamine, Gladion and Lillie are not ultra beasts since Mohn may be the father?
