The Gentleman Headcrab is a funny enemy from the Crack Life mod for Half-Life 1. The Gentleman Headcrab is dapper, fancy, and goofy, and its diet mainly consists of flesh. The Gentleman Headcrab is silly in its dapperness and fanciness, but is still aggressive like normal headcrabs. However, the Gentleman Headcrab tends to make very fancy quips even when it is being aggressive. The Gentleman Headcrab denies its aggression in a humorously dapper manner even when it's attacking. Fancy and vicious.
