I wouldn't call this a custom , since I didn't make anything , thus in my mind this is a diorama (a combination of various things to make a scene or picture) , basically I used a New Marvel Legends Ghost Rider and gave him a ride in this case a Megabloks Ice Dragon (since it look skeletal and the blue detail match my Rider who also was blue), play a little with the dragon to make figure fit and look more natural and finally gave them a Halloween Skull necklace so serve as the GR's chains and the Dragon reins , again not a custom , but a nice combination worth seen , Enjoy !!
