HTOTM: FUSION
alter the legs to be the wheels and the body be the car with arms and head being steering and the dangly thing on the top respectively and it would work.
You don't even need that for steering. To steer, you'd just have wheels on the right turn one direction, and the ones on the left turn the other.
I know how to but i mcrap at modding you could use 2 strings on a piece going across the bottom of the car at each end of the piece theres wheel thaat spin. you pull one of the leads and it turn that direction x]
Whips
A whips mod with a curved shield so that blows will glance off instead of smashing in at a straight angle from the start. I think it would be cool because if you used the wrong angle to defend it could glance off and hit the head for a decap.
