Like the rest of the Alien Rangers, Cestro shows a logical, rational demeanor when dealing with others and a respect for water-life. Cestro, like Billy Cranston, seems to enjoy tinkering with machinery and act as the Aquitians' machine-manager. In battle, Cestro shows the tactful elements of a strategist; particuarly when it comes to his hydration management.
