Dreamer is a highly ambitious Salamence, true to her name. She quickly evolved and achieved her initial dreams of flight, gaining a reputation as one of the most fierce, skilled Salamence who ever lived. Eventually, she recognized her talent, and, thinking her own kind too lowly, sought to gain more power, even seeking fights with legendaries.

However, she soon encountered Dialga. She challenged the time lord to a battle over his power - and lost. She was turned into a Wurmple as punishment, but, seeking out Darkrai, regained her old form, and still plots against Dialga as Darkrai's servant.
