>>45083365The amount of grasping at straws you're performing right now to avoid recognizing something so obviously simple is frankly ridiculous.
Togekiss, the Jubilee Pokemon, has multiple dex entries expressly related to it's abilities of offering blessings and avoiding strife. Milotic is said to arise during times of strife, and then remove said strife by calming the hearts of the people involved. The connection is there, and obvious, that a key theme behind many fairy types and fairy-adjacent pokemon is either the avoidance or quelling of negative emotions, something that shows up in their type effectiveness as having the advantage over dark.
To spell this out for you in the plainest terms-
>SylveonBy releasing enmity-erasing waves from its ribbonlike feelers, Sylveon stops any conflict.
>MiloticIt's said that a glimpse of a Milotic and its beauty will calm any hostile emotions you're feeling.
You're wrong about Heal Pulse in either case, as nothing about Milotic's dex entries refers to it being capable of healing other pokemon, only calming them.
