I took the liberty of dirty-sketching my basic Idea of how I'd imagine it's position.
The elements would be Ice, Metal, Electric, and Terra.
The jacket would be Light blue, the scarf and boots would be Black, The dragon itself would be a Neon Green or Lime with Golden Horns. The eyes are blue, the underbelly is yellow, and the pants are Dark Grey.

This Dragon's rarity is VR.
