Shapemaster 

One who has mastered the art of forming shapes.

This is derived from the supervillian of an educational comic series that teaches math to children. He wears a blue morphsuit and can transform himself into a wide range of geometric shapes that are always blue and always have the same volume.

Last night Andrew turned into the Shapemaster again and entertained the crowd by forming a variety of hexagons and parallelograms.
