The two takes the appearance of a dual-headed pale blue Serpentine-like dragons with dark red eyes. They both have two spikes on their heads and spikes running down their backs. They also possess a pair of pale blue dragon wings and four legs.

Hong and Jiang also possesses the power to temporarily turn into two human twins with spiky pale blue hair and red eyes. However when in this form they couldn't get very far apart without being forced back together into dragons.

Trivia

 * I didn't want to go with the whole good twin, bad twin thing because that's stereotypical and has been done to death so I went with both twins having both good and bad traits.
