The Lava Dragon is a Fire/Earth hybrid dragon in the game DragonVale.
The lava dragon was the first to undeniably establish that some dragons use magic to fly. While its wings are more than enough to bring it aloft as a juvenile, they remain the same size throughout its life. This creates a somewhat awkward looking adult appearance that it probably wouldn't enjoy you pointing out.
The Lava Dragon can be bred by using any two dragons, in either order, containing the Fire and Earth elements.
