I created this using Mother 3 soundfonts (instruments used: Celesta, Piano 1, Harp, Pipe Organ), church bell soundfont from the SJO (Saint James Orchestral) Soundfont collection.

Comment: Ahhh... The theme song for children and short people in general. Allister is just a child aged between 6-12 (in my view) who prefers to be alone in cemeteries or ruins. In my view, he is just concealing his huge powers as an embodiment of the Christ, waiting for the right time to perform a miracle where he resurrects the dead in the ruins or the cemetery he visits. Sounds illogical to you, but for me, it is entirely possible (Due to the cursed image comparison of him to the Jesus-inspired character, Iesua Nazarenus).

Speaking of ghosts, they are just spirits of the dead who have yet enter Heaven because of their tight bond with the mortal life. Allister, being able to talk to ghosts (especially that of deceased Pokemon), he understands their wish to fulfill something that they have missed out in their life, and sympathizes with them (but for evil spirits it is the reverse) and loves them with all of his heart.

I make this track sounds both spooky and majestic at the same time, using instruments most commonly found in music heard in churches (i.e. pipe organs, church bells). It sounds like a piece of music for a teeny child who can speak to ghosts but also emanates spooky and majestic divine auras at the same time. The parts that I use the Celesta and the Mother 3 Piano instruments represents his childish part, as it sounds like twinkling stars in my opinion, and due to the song "Twinkle, Twinkle Little Star", I associate the sound of twinkling stars to children as well, and the piano instrument I used in this track sounds a bit "childish" as well. The rest represents his dual nature of spookiness and majestic divinity.

Overall, this is a track that combines the divine sounds of church music and the spookiness of stereotypical horror music, to portray my view about Allister - a child who is secretly an embodiment of a divine being (just my opinion, nothing serious here (but I'm secretly an Allister worshipper (believe me, video game characters can sometimes gain parody religions IMO))) who can speak to ghosts and have pity on many of the ghosts' impossible wishes when they were still alive.

To @LUKELCS with L.O.V.E. Hope you enjoy this (amazing and spoopy) music video. But it's a bit cursed, so I hope you do not get mad because I portray a video game character as Jesus.
