>>56414181Personally I like to interpret her character arc as a composition of the games and anime
She starts out as an overbearing, but well meaning mother until they lose Mohn, where she becomes more distant as she focuses on bringing him home, even weaponizing Cosmogs to do so
By the game starts, she's been undergoing a sanity slip due to a combination of stress and exposure to UBs like Nihilego and ends when she snaps and fuses with one, hell maybe even Necrozma itself
By the post-game, she's steadily recovering but willing to make amends with the family she lost herself trying to save
