Bula is a green alien and one of the main protagonists of Zula Patrol. He always desires to help others on their tasks, including his crew which help himself as well.
Bula is compassionate, patient, and likes to assist other characters in the series. He can worry a lot, though, and likes things to be set on a schedule. He is fairly intelligent like Zeeter, and has an interest in the solar system and constellations. He is best friends with Zeeter, and he can remember the time when he, Iris Bloodshot, and Zeeter were in Zula Scouts. While he is often the one trying to keep his teammates (especially Zeeter) out of trouble, his own cluelessness can often land him in trouble of his own. He is known to be quite serious when it comes to missions, and never backs down in the face of danger. In "Bula's Heroes: The Great Camouflage Caper", he had a fear of bugs, but later came to love them after they saved his life.
Bula is a bright-green alien with a dark-purple zipped-suit that serves as the main outfit for the Zula Patrol. He has thin arms that reach down to his legs, eight fingers (four on each hand), and a short-stalk of red-hair. He also has two green antennae on his head.
However in the fourth season, Bula's appearance has changed drastically due to his growth. He now does not have the original suit he had in the first 3 seasons. Instead, he wore more of an armor-fashioned space-suit, and he is much more muscular in the upper body as well. His hair has also changed; instead of the bright red stalk he had originally, it is now curlier and browner than before, looking almost maroon in color.
