Zip was born in 2268 and acts as one of the occasional scouts and scavengers for Little Lamplight, which perfectly suits his speedy and hyperactive nature. As a bonus, it allows him to have first dibs on any Nuka-Cola he can find, a drink he's quite addicted to. When he's not out finding resources for the town, he runs around town, pestering people and generally being feisty. MacCready insists that Zip doesn't get to keep his gun when he's back in town...not since that accident a while ago.
He isn't sure why he is called Zip. In his own words, "Why Zip? Or why do I have a nickname at all? I mean, why don't people just call me Ricky? Or Yancy? Or Eustace P. Vanderbanger the Third? People say it's because I'm so fast. But, I don't think I'm that fast, it's just they're all slow."
