Grebleips was the senator for the planet of Brodo Asogi in the Galactic Republic from the years leading up to the Battle of Naboo until shortly after the formation of the Galactic Empire. When, in 32 BBY, Queen Amidala of Naboo called for a Vote of No Confidence in Supreme Chancellor Finis Valorum, Grebleips and his delegation were present, joining the fracas that ensued throughout the Grand Convocation Chamber. Shortly before the Clone Wars, Grebleips funded an extra-galactic survey. As the war neared its end, he became part of a Delegation of 2000 legislators who filed a formal protest against Valorum's successor, Palpatine, for actions they perceived as unconstitutional. When Palpatine turned the Republic into the Galactic Empire, Grebleips was arrested by Imperial Intelligence on charges of conspiracy and treason, for plotting with the Jedi Order to remove Palpatine from office.
- "Grebleips" is "Spielberg" spelled backwards, a direct reference to director Steven Spielberg.
