Gilbert Huph is greedy, impatient, and self-centered. Despite being the boss of an insurance company, he is more focused on gaining more money than providing clients with the insurance they need and scamming them out of their insurance money. As such, it is heavily implied that he has no qualms about illegally denying his clients aid. He always seems to have an excuse for getting angry, and only cares about money. Gilbert Huph also seems to talk down to his employees, as evidenced by his conversation with Bob in his office, treating him and possibly everyone under his employ like children who don't know what they're doing.
He has no concern for anybody's well-being other than his own, as shown when he stopped Bob from helping a man being mugged with the threat of being fired. He is obsessed with bureaucracy, furious when clients (Bob's) use loopholes to circumvent various technically legit methods of denying them claims of insurance.
He is always annoyed that Bob keeps authorizing payment on insurance policies to different clients, even if it is part of their coverage. He reprimands Bob, asking him how Insuricare can remain profitable when Bob writes checks to every "Harry Hardluck" and "Sally Sobstory" that gives him a phone call.
Mr. Huph figures out that Bob has been guiding customers through the legal loopholes to get the insurance they need, and calls him down to his office. During this discussion, Bob sees a man being mugged just outside the window, and tries to alert Mr. Huph to the man being mugged, but when Huph sees that the man is getting mugged, he nonchalantly remarks that he hopes that he isn't insured. Bob tries to go and save him, but Huph threatens to fire him if he leaves his office. Bob then sees the mugger running away and succeeding. Mr. Huph then tries to tell Bob that he was close to losing his job, but Bob (enraged that he failed to save a citizen and disgusted by his boss' callousness) snaps and loses his temper, brutally grabs Huph by the throat, and in his rage, throws him through five walls, severely injuring him.
Huph is then hospitalized, in traction, and possibly mind-wiped by Agent Rick Dicker. However, Mr. Huph survives and tells Rick that Bob is fired.
It is unknown what becomes of Mr. Huph after The Incredibles, but he most likely recovers from his injuries and goes back to work. It is also implied that his company went out of business or himself ends up getting fired due to his illegal practice of denying people rightful insurance claim.
- He is the second Pixar character to be voiced by Wallace Shawn. The first is Rex in the Toy Story franchise.
- On the "October 2005 WDW Pin Releases" website, there is a pin called "Boss's 2005 Day", where Bob is in Mr. Huph's office giving a present to his boss (whose arm is in a sling, presumably after the freak accident he had in the movie) for Boss's Day 2005. The words said "Bob Parr is presenting a gift to Mr. Huph for Boss's Day 2005. Remember your boss in 2005 with this unique Limited Edition pin featuring characters from The Incredibles. Boss's Day is celebrated every October 16. The pin was designed by Disney Design Group Artist Bret Melvin".
