Tubal

Tubal is the commander of Prince Leontes van de Montague's personal guard and a supporting antagonist in the anime Romeo x Juliet.

History
After Romeo left to run away with Juliet, Tubal was ordered by Leontes van de Montague to track him down. Tubal discovered the two in a remote village and took Romeo to bring him back to Lord Montague. Upon discovering that Juliet was the surviving heir of House Capulet Tubal captured her too to bring her to Lord Montague as well. However, with help from Romeo Juliet managed to escape.

Later, when Juliet and Romeo led an uprising against House Montague with the support of most of the civilian population, Tubal and his guard protected the palace. Despite being ordered by Lord Montague to kill any deserters, Tubal allowed his men to leave if they wanted and let Juliet and her forces go past.
