Calyrex has two other forms, which are activated by using the Reins of Unity on it and either Glastrier or Spectrier, resulting in a process that removes Glastrier or Spectrier from the party until the fusion is undone. It will then become Ice Rider Calyrex (Psychic/Ice with Glastrier) or Shadow Rider Calyrex (Psychic/Ghost with Spectrier).

Cinderace is a bipedal, lagomorphic Pokémon with white fur, a red fur tuft on its head, and large ears, each with yellow insides. On its torso, there are black "shoulder bands" over the arms and a "cleavage marking," which gives the impression of a tank top. On the bottom, it has red haunches with one yellow stripe on each side and fluffy cuffs, which give off the appearance of shorts. Its legs are mainly black with red-tipped toes.
