I have some theories:
1. Metsu could have the shape of an S which looks like a spiral.
2. Dr might be called Drill. That would fit the spiral driver.
3. Zwei might have 2 dragon heads with metal on them. This could be an homage to L2 since it was the first Bey in the Dual Layer System to have additional Metal on the layer of the Bey.
