Selene

Selene is one of Serena Millicent's three wolves, along with Echo and Helios, who were presents from her her aunt Anita and cousins, Ruby and Dorothy.

Regina and Robin were hesitant to accept the gift because they were afraid that Selene and her brothers would attack the younger children of the town, as well as Serena's younger siblings. Anita assured them that all three were the docile kinds of wolves and that they behaved just like the average dog when trained. Serena named her Selene after hearing the species of the wolf as well as the moon goddess. Selene is a rare Moonlight Wolf that unfortunately transforms into another mythical beast, such as a dragon or a hydra. The wold its self can not control this, even with the proper training. So she and her brother Echo (He's half Moonlight Wolf) unfortunately transform from wolves to another creature some nights.

But, she has been trained to do other things. Basic things like "Sit", "Roll over", "Lie down," and to not go to the bathroom in the house. Buts he's also been trained to hunt alongside Serena, her brother and their father, fetch her potion ingredients and to be calm during fireworks on the 4th Of July or gunfire during hunting season. Selene has had addition training so she can point out constellations in the night sky.
