Cyandog

As its name implies, Cyandog is a blue Medarot that resembles a dog. It has a lightning bolt symbol on its forehead. The rifles on his arms allow fast shooting attacks. While not a particulary powerful Medarot, its high speed can be used to its advantage. Cyandog is Iwanoi's signature Medarot for the first half of the series. Iwanoi's Cyandog uses a Monkey Medal, which isn't compatible with its shooting parts. Cyandog, though, was loyal to Iwanoi, similar to a dog being loyal to its owner. Later its parts were replaced with the DOG-1 Bluesdog parts.
