Gilbert Huph is cold, cruel, greedy, selfish, 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. He always seems to have an excuse for getting angry, and only cares about money.
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. Hugh 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. Bob then sees a man being mugged through 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's apathy) snaps and loses his temper, brutally grabs Huph by the throat, and in his rage, throws him through 5 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.
- Mr. Huph's obvious disdain from helping his clients is in stark contrast to his voice actor, Wallace Shawn, who apart from being a playwright has studied economics and political science, and knows full well of the dangers of extreme capitalism. Shawn makes an appearance in Capitalism: A Love Story, directed by his good friend Michael Moore, and with Moore discusses this subject.
- 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".
