Harold Pontiff Coomer, more often known as just Coomer, is a sentient scientist NPC from a special copy of Half Life 1, a version that found itself in the hands of a streamer who played the game while acting in character as Gordon Freeman. While he can be a bit cuckoo and violent at times (most frequently shooting random scientists dead), he sports a happy go lucky attitude and optimism, being a very loyal friend even after finding out that he's merely a video game character.
