Quite a few years old, but I still really like the concept. Someone challenged me to design rotom...but rat. It's a long story. (shiny form)

Alt text: A drawing of the shiny forms for a rat fakemon with six forms named radapt. The base form (bottom right) is a normal/poison type grey rat with multicolored eyes. The lightbulb form (top right) is a yellow electric/poison type with a broken lightbulb on its head and a bolt of electricity between its ears. The bottle form (middle) is a blue water/poison type with its lower body stuck in a water bottle, turning to liquid. The match form (bottom left) is a red fire/poison type with flame-shaped fur and a used match in its tail. The skull form (middle left) is a purple, levitating fire/ghost type anchored by a skull in its tail. The banana form (top left) is a green grass/poison type with an darker green banana peel on its head.
