Darnold

"PRESS ALL BUTTONS TO UNLOCK  DEVIL GUN MODE!  " -Darnold The eccentric head of the Black Mesa Mixology Department, Darnold specializes in making potions and new brands of Powerade, though Gordon points out that potions are not real and are primarily associated with wizards. Darnold gives Gordon a potion contained within a barrel that causes a large gun to grow on the stump of his arm, and he decides to join the main cast shortly afterwards; however, upon realizing their violent nature and his own inability to handle danger, he immediately decides to leave them and flies up an elevator shaft on his rocket boots. He later returns in AI Crushes All Banks as “the guy in the chair,” and indirectly aids the crew in their bank robbery. Darnold is voiced by Logmore.

Trivia

 * Darnold has a computer with a pirated copy of Grand Theft Auto: San Andreas and Team Fortress 2.
 * Strangely enough, he hasn't downloaded the Pyro update for the latter, despite it coming automatically installed with the game when purchased.
 * When he is first seen, he is counting near his computer up to 23 (although he is not seen counting the other numbers). When he stops at 23, he then says '23 unique flavors!', which may suggest the mixture he was making was either inspired or is Dr. Pepper.
