Because of their dual personalities, Duotone Dragons are extremely nervous and indecisive. When confronted, it is often the case that one head wants to fight while the other wants to run, resulting in the dragon trying to go in two directions at once. They are omnivorous, choosing to eat both vegetation and meat—although perhaps this is just another outcome of their indecisiveness.
Both heads can control the body, with each head having only marginal control on the opposing side of the body; this works when both halves want the same thing, but does not work as well when there is a disagreement. Despite this, Duotone Dragons can fly quite well, but can crash through the trees if one head becomes distracted.
Duotone Dragons can fight, using their large claws and heavy face plates to rend and bash their opponents.
Two-headed dragons are unique enough to deserve a separate classification from “regular” dragons. They have two necks, two brains, two mouths, but one stomach and one main body. The two heads usually work together, but there are times when they will fight each other, snapping back and forth. Their unique anatomy prevents them from breeding with single-headed dragons.
Girasol and Pharalune are an interesting pair of heads. Accustomed to sharing a body, the two regularly swap between having one head control the whole thing (when the other is sleeping) or each controlling their own side; in the former case, however, movement is clumsy and so each will wake the other if a problem arises.
Pharolune, the purple head, is rather subdued. Having been betrayed by who he thought was a friend whilst Girasol was sleeping, he is distrustful of dragons besides his other half. In contrast, Girasol is an expert at communication, often acting as a peacekeeper should issues occur around them - which they often do.
Even with the personality clash, there is no doubt that they are less indecisive than a lot of Duotones, due to the simple fact that they love each other for who they are and will try their best for each other at all times.
