The Kaijin my rider has to fight are called Sprockers, coming from the word Sprocket, as they are created from Gears made from a adaptive metal that absorbs the unique qualities of what first touches it that's not natural or is alive, so if its alive, made by man, or is organic in anyway, the gear will either absorb just the properties and change into a Sprocker, absorb the very thing that comes in contact with it, or absorb the properties and become apart of a Torstage gear set, which will work in my riders driver. Defeating these Kaijin will release the gear, and turn it into a single section part of a Torstage set. These Kaijin are lead by three higher class Sprockers, the first Sprockers, who were made by humans to control these gears, their bodys are made of a fusion of the metal the gears are made of, human DNA, and the absorbed attributes that go with them.

Tentrage is the leader, extremely powerful, like to toy with his opponents and has a tendency to take thing seriously. He has the attributes of a Nuclear powerplant.

Kitsuryu is Tentrage's second in command, while not as physical powerful, she makes up for that with skill and her abilities, but she is as Frail as she is shy, which is saying something. She has the attributes of a Fox, which is why her name begins with Kitsu, from 'Kitsu'-ne.

Denshasa is the military type commander for Tentrage as he isn't very good with that type of thing, as well as a doctor, shes intelligent, skilled, powerful, and quick to tease her opponents in a playful manner. She has the attributes of a train(steam), so she'll carry her allies well in battle. Her name comes from the Japanese word Densha, which is Japanese for Train.

These three are able to use the Torstage section pieces to enhance themselves temporarily. They can only use one at a time, not a whole set. But they have to take breaks from each one.
