Mars Guo was a male Bardottan who participated in Podraces during the reign of the Galactic Republic. The thin nosed Guo preferred a very large Podracer which, despite its size, was rather fast. Guo participated in the Boonta Eve Classic during the Invasion of Naboo, and was able to stay among the leaders for the majority of the race. Guo held second position during the second lap, right behind the crowd favorite, Sebulba.
