He is fatter and bigger than an average Galvan and wears a plumber suit.
By Galvan standards, he is not considered to be very smart, though he and Blukic were shown to be intelligent enough to repair the Omnitrix in Outbreak. He is somewhat more level-headed than Blukic, though that isn't enough to keep them out of trouble. Like his partner, Driba is quite fond of Mr. Smoothy.
Powers and Abilities
Like all Galvans, Driba is small enough to enter machinery and tight places that larger beings cannot.
By Galvan standards, Driba and Blukic are not considered as very intelligent, he is still able to understand scientific theories and complex machinery far better than any scientist or engineer on Earth.
Like Blukic, Driba is able to improvise repairs and devices during dire situations and they were also able to repair the Anihilaarg and the Omnitrix.
Both he and Blukic were once part of the Level 1 Science Team, which causes Driba to shudder in fear of being demoted back down to. In Evil's Encore, it is shown that they had been hired five years previously to be part of the tech support of the Plumbers. One of their first blunders was when they received an order to create an escape tunnel, and they built a tunnel only big enough for Galvans and other smaller species.
