Look like 20yr human man but is can turn into a Samurai Dragon (https://www.dragon-mania-legends.wiki/wiki/Samurai_Dragon), gender is male, his Hair color is Royal Blue, his Eye Color is brown gold, covered in a lavish set of lamellar armour. Rich tones of gold, deep red, and creamy white are used to create a suit worthy of a traditional Samurai warrior, without his helmet, he has sworn an oath to protect his Emperor (https://www.dragon-mania-legends.wiki/wiki/Emperor_Dragon). Everyone finds its loyalty an endearing quality... up until it tries to defend his Emperor from bath time,
