The clockwork varanius is a very limited adoptable that has only been given out to the winners of the first Official Fanart Contest.
The clockwork varanius is similar to the original varanius adoptable, but is not "skinned", the mechanical parts of the construct visible. There is no difference between the three omega forms aside from the metal they are constructed from-- the natural is made of brass, the vital of copper, and the tainted of iron.
In-Game Description Edit
"Crafted of the finest metals, the clockwork varanius is an industrial-grade model of the popular robot series. Housecat-sized, unskinned and extremely durable, they are part of a super-limited production run!"
