dragon lore

Did you see the earlier commens, the ones just before you?
The one you marked as YELLOW is Tiamat, check the game and the picture again and you will see very cearly evidences. Mouth, horns, and scales behind the face.
The one you marked as PINK is the unknow dragon. It has to many inconsistentces with Tiamat on Hw.
And no if you watch Main Scenario, the primitive images of Ratatoskrshow show that she doesnt have enormous peak, she has 4 horns behind her face. On may opinion Ratatoskr would be the one you marked as LIGHT BLUE.
With the images of Bahamut, the one that most look like him is the one you markes as GREEN. Bahamut doesnt have 2 horns on that form.
