Flint (older brother)
Buck is the impetuous younger brother of Flint.
Buck appears after Platinum defeats Darach; he may have watched the battle. He says that he's been trying to find Looker ever since he caught Looker sneaking into the Battleground, and cut into this conversation because he heard them mention Stark Mountain. He tells them that Team Galactic has been hanging out there a lot recently and Buck suspects that they're after Heatran. Buck then refuses to bring Looker to Stark Mountain, telling Looker he dislikes how great the police make themselves out to be, and runs off to Stark Mountain himself, stealing Looker's photograph of Team Galactic.
He is reckless.
