Here is the final round of thumbnails, I think I found a couple of them I like and I am going to iterate more detailed images on. I like the idea of him having ski poles to assist him in turning and to use as a weapon. I imagined that the ends of the poles are like tesla coils.
Another idea was that the cycle was actually a hoverboard, giving him a Green Goblin posture, but then I lose the leg action of the unicycle.
Lastly, I thought what if the cycle wasn't a wheel but a ball. There would still be the pedaling action but the "feet" or metallic ends of the legs would enter the ball to pedal for motion, and to attack he would kick from the ball, pulling energy with it for like an electro-kick.
