A revolutionary, Escuella was a firm idealist who held loyalty above any other virtue and could passionately devote his life to a cause. This allowed him to connect with Dutch, who Javier remained unwaveringly loyal to throughout the time they knew each other.

However, Javier is shown to be quite vain and loves to flirt with women.
