 * Gemini - A two headed, six legged reptilian creature. It has feathered manes around its heads and its bite and breath have so much bacteria it can cause things to decay and/or die. It can also instantly regenerate any part of its body (even being able to regenerate a third of its heart, its eyes and less vital parts of its brain), similar to an axolotl.
 * The Night Terror - Resembling the cross of a pterosaur, bat and penguin, it appears at night in fear of the sun’s heat (which will cause it to heat up so much to the point where it is unable to regulate its body temperature). It causes the water vapour around it to freeze instantly when it flies, causing massive hailstorms.
 * The Green Lion - A green, metallic lion, it secretes a liquid which dissolves all matter except gold. It has a violent and destructive nature, attacking and destroying anything in its path. It derives its energy from the sun, essentially “devouring it”. Any living being which enters the radius of its path will be overwhelmed with violent and frustrated desires for a period of time (prolonged the longer the organism remains in the radius).
