Transformation Sequence Types

World of Light
The transformee rubs the Chris McLean Brand Ring (if they have one), and light shines from it. The light engulfs the user, with the shape of the light twisting and reforming until it creates the shape of the user's mon form. The light then fades, revealing the user has become the mon that represents them best. This is used from Welcome to the Wawanakwa Region! to DJ's Trial!.

Full Sequence
We actually get details of the transformation, kind of like one of those TF stories or TF comics you'd find on Deviantart.
