Pyre is a fire-breathing dragon, if you couldn't tell. He has unlimited energy, does not need to rest, and doesn't need to eat. Water does not kill Pyre. While being a slight annoyance- if not enough water is supplied (a spray bottle's worth is insufficient, while a fire hydrant is enough), that specific section of their body will burn brighter.

Pyre is energetic and chaotic. He does not act aggressively, but he doesn't see the point of making friends.
