FillyLight: This small, rare ponymon is light-hearted and playful. They enjoy games, and honing their considerable psychic powers with their follow FillyLights. These ponymon are curious and impulsive, so trainers should keep a close on them.
 
DarkLight: When a FillyLight loses its closest companion, its grief corrupts is playful heart. The FillyLight will flee to a dark cave to isolate itself from other people or ponymon. When it emerges from its cave decades later, its bright, cheerful smile hides dark intentions. DarkLights seek out weaker ponymon, especially FillyLights, seeking to take those closest to them away so all ponymon know its pain. Trainers are advised to stay away from DarkLights, as their unpredictable nature and extreme power combined with their barely restrained emotions make them highly dangerous. DO NOT ATTEMPT TO BEFRIEND A DARKLIGHT!
 
StarLight: DO NOT ATTEMPT TO BEFRIEND A DARKLIGHT! Only by befriending a trainer, can a DarkLight start to shed its grief-fueled darkness. When a DarkLight risks its life to defend their trainer, it sheds the last of the darkness clinging to it, evolving into StarLight. You will often find StarLights carefully watching over FillyLights and other young ponymon, keeping them safe from DarkLights seeking to do them harm.
