This is Sapphirus's New Look, her true form (the facial face and a little redo to the horns). This is a WIP, she's basically bigger than planets, her length is long enough to wrap around the sun almost twice. She's a Feathered Chimera Easter dragon. She's a planet repairer, etc.

She can take an earthly form of this, would be the length of the wall of china. Weight is unknown in both forms.
