Considered by Alex to be a rare gift, Jupiter is loved dearly.  She is dear friends with Cosira and Imber and understands the strange glances they all get, and the shyness Cosira exhibits because of it.  Jupiter is much more sociable and doesn’t mind being handled by humans other than Alex and tries to encourage Cosira to come out of her shell.

Carefree and a little cheeky she occasionally starts things with the other young foals she may not be able to finish, and as a lover of water, her as yet untrained abilities can cause havoc.
