"I'm only carrying out orders, Zorran can't blame me!"
Zug in, Trapped

Zug is an ambitious, young tug who is Captain Zero's fourth tug, and one of the Z-Stack switchers. He is usually seen working with Zip. He is used for a wide variety of tasks around Bigg City Port. He speaks with an Estonian accent.


Zug mainly works with Zip, and likes to think of himself as the intelligent one. Compared to Zip, he certainly is intelligent and practical, but he is not as smart as the other tugs. He comes up with devious plans for him and Zip to use when faced against the Star Tugs. He is a scheming sort of tug, though his plans rarely if ever work as planned. With Zip, Zug basically commands him, who's too frightened to make any good suggestions.

Zug's capabilities range from the towing of barges to liner docking operations. Like the rest of the Zero Marine, he is based on the Moran Fleet tugs of the 1920s.

Zug is sneaky, cowardly and he needs the other Z-Stacks around for courage. He is intimidated by the main Z-Stack Zorran and has a tendency to be somewhat nervous and jittery around him and the other harbor tugs. However, as seen in Trapped, he did initially keep his cool while around Zorran, only to panic when Zorran's impatience landed the smaller tug in trouble.

However, like most of his crewmates, Zug is shown to have a good streak in him somewhere. At one point, Zorran callously abandoned him trapped Up River (with seemingly all the Star Tugs, but it turned out only most of them were trapped) when they accidentaly crashed an old tramper across the river. Zug worked with the Star Fleet to get it out of the way since he was stuck on the other side, but he never complained. He was also shown to be very supportive towards O.J.'s plan to ram it with a line of barges, despite it not working as expected; he even helped out in the attempt. After they were all freed when Billy Shoepack effortlessly helped by blowing up the tramper with dynamite, Zug laughed at Zorran with the Star Tugs.

Zug has also proved to be suspicious and brave when trying to figure and capture the pirate after Ten Cent's barges keep disappearing. But when following Ten Cents, and Sunshine to see what they're up to, he and Zip end up finding a fright when they are chased by two green-eyed tugs.

Zug and Zip are the Z-Stack equivalents of Ten Cents and Sunshine, in that they are the smaller tugs of the fleet, who work together and are plotting against the other two. Zug has major roles in most episodes, and a majority of stories focus on him as a major character in some way.

Zug's whistle has a hooting quality that sounds very much like a squeeze horn, but deeper.
