Compared to his hot-headed brother, Lauda normally maintains a cool and rational demeanor, though there are still times when he lets his emotions get the best of him. Despite being an illegitimate child, he is fiercely loyal to his family, especially to Guel. However, because of this, he tends to let his brother off the hook for some of the latter's more unsavory behavior. It also caused him to develop a grudge against Suletta Mercury, unfairly blaming her for all of Jeturk House's troubles. On the other hand, he is also capable of being grateful to others for their assistance, thanking ChuChu for defending him during the Open Campus Attack despite her being an Earthian.
