The lion was constructed for the prototype. 3D Studio Max was used to build the wire-mesh frame, and then Adobe Photoshop was used to skin the creature. The skeleton was added, which was used by an animator to perform movements. The good creatures' appearances were the most problematic, and the transformation between alignments was also thought to be "a huge challenge". Each form was built from seven meshes and three texture sets. This enabled subtle variation. The eyes were originally painted as a texture, but this was deemed "unsatisfactory". Later, the eyes were built using separate geometry that moves independently, and were added using the game's creature editor.
