Dragoon is a series of Dragon type monsters. They vary in color and design but the regular monsters are usually smaller looking and the fusions are huge. They're multiple colors and colors fuse together to create new ones.
Play Style Edit
Dragoons focus on fusion summoning and increasing the ATK and DEF of one another to get a beat down strategy going as well as good protection and recovery. Later, the "Dragoon Nova" monsters were released. Which are upgraded versions of the Dragoon fusion monsters used by using "Dragoosion II".
