Ruffnut and Tuffnut are Berk’s chaotic twins, bringing equal parts mayhem and misplaced confidence to the dragon training arena. Wildly competitive yet equally unskilled, they turn even the simplest drills into spectacles of absurdity. They throw themselves into every challenge with reckless enthusiasm, convinced that confidence alone will carry them through—despite all evidence to the contrary. Their relationship is a constant battle of one-upmanship, driven by rivalry yet bound by an unspoken loyalty. They bicker endlessly, but when it matters, their bond is unshakable—though admitting it would be out of the question.[src]
