Dr. Zed

Dr. Zed Blanco lost his medical license for unknown reasons. Currently, he maintains the medical vendors around Pandora, more or less. He spends much of his time in the infirmary in Fyrestone (and later New Haven (and later still, in Sanctuary)) chopping up corpses for unknown purposes (perhaps related to his loss of medical license).

Involvement
Dr. Zed is the only human resident of Fyrestone met by the Vault hunters. After Marcus Kincaid the bus driver, he is the second friendly human NPC met in the game. He gives out some of the initial missions. Additionally, he (more or less) keeps the Med Vendors running.

Between the events of Borderlands and Borderlands 2, Roland contacted Zed, asking him to move to Sanctuary. Zed initially declines, preferring to live and die in Fyrestone, but quickly changes his mind when Hyperion attacks the place in the middle of the conversation. Mr. Blake contacted him, informing him that Hyperion assassins were on their way to Fyrestone, as well as secretly helping Zed evade the assassins and reach Sanctuary.

Trivia

 * Dr. Zed is introduced waving a "buzz axe". This same type of melee weapon is later encountered in the hands of Psychos.
 * His name is strikingly similar to "Dr. Ned" a mad scientist that is the main character of the official add-on content "Zombie Island of Dr. Ned". During the Zombie Island of Dr. Ned storyline Dr. Ned calls himself Zed's brother. Humorously, in the intro of The Zombie Island of Dr. Ned Marcus Kincaid says that Dr. Ned is "totally not Dr. Zed from the last story at all". Similarly, Ned himself will repeatedly deny being Dr. Zed in disguise.
 * Dr. Zed has his own white and red Claptrap in New Haven. Ironically, he doesn't seem to even notice that the Claptrap is there, besides the fact that the Claptrap will try to communicate with him.
 * Dr. Zed has an invisible barrier spreading a few feet in front of him which protects him from grenades, but bullets can pass through.
 * Dr. Zed's design is based off of the initial concept art of Roland.
 * Zeds are a common term for a zombie and ironically it is Dr Ned who raises a zombie army instead of Dr Zed.
 * In Borderlands 2, it is revealed that he is actually born in Fyrestone.
 * In Borderlands 2, when shopping from Dr. Zed in Sanctuary directly, it still plays audio clips from the vending machine. He also shares items with the vendor on the left of where you enter.
