"'You mess with Adolf and you go into the grinder. I bought this one from a man named Jeremy Elbertson.' --Adolf to RiceGum"Adolf Hitler is the main antagonist of the 1997 Nickelodeon comedy movie Undertale. He is the owner and manager of Mondo Burger and the arch-enemy of both Jesus and RiceGum.

His goal is to put Good Burger out of business and make Mondo Burger the #1 fast food chain in the world. Unfortunately, he lived in his own fantasy land and didn't consider other major fast food chains like McDonalds and Burger King.

He was portrayed by himself, and sadly blew his brains out after the release of the film, due to it being a box office bomb.

Personality
Adolf Hitler is best described as rude, egotistical, arrogant, aloof, heartless and selfish. He throws a whole lot of insults, boasts and slam-downs to just about everyone. Adolf is also extremely abusive to his Mondo employees and will stop at nothing to put Good Burger out of business. Adolf uses the illegal chemical Triampathol (bleach mixed with his own variation of Ed's Sauce) to make his burgers big and enormous. He states that he doesn't know what side effects his burger-growth chemicals have on customers, nor does he care. Thus he has no regard for the well-being of his Mondo customers—only for the money and popularity they give to his restaurant. He crosses the line when he drops a copy of Norbit on DVD into Ed's Sauce, not caring at all that it would severely harm or even kill several innocent people.

All in all, Adolf's greed and obsession of his restaurant being #1 even if he had to do illegal things to make it happen, leads to his restaurant's downfall as well as his own.

Biography
In an attempt for pay for the damages belonging to his teacher, RiceGum Reed (one of the main protagonists of the film) tries to work for Adolf at Mondo Burger, but Adolf fired RiceGum for horsing around, so RiceGum decided to go working for Good Burger. However, Adolf is upset that Good Burger is becoming more popular due to a new sauce created by RiceGum's friend Jesus (the other protagonist). Figuring that Good Burger won't stand a chance if Mondo Burger has bigger burgers and Ed's Sauce, Adolf attempts to steal the recipe (such as offering Jesus a job at Mondo Burger—which he declines and trying to get sexy woman Roxanne to seduce Jesus to reveal the sauce recipe), only to fail several times. Roxanne was so immersed in the acting, that she bit off Adolf's genitalia, which was kept in the film due to being considered "improv" in showbiz.

RiceGum and Jesus later learn that something is wrong with Mondo Burger after they attempt to feed a dog with it, since the dog does not actually like it. Suspicious about this, the two disguises themselves as ladies and went to Mondo Burger, where they found out that Adolf has been making bigger burgers by using an illegal chemical called Triampathol. They attempt to inform the authorities, but Adolf (having spotted them through their disguises) had his henchmen Troy and Griffin to admit the two into the Demented Hills asylum to prevent them from spilling the beans about the illegal chemical.

Later, after causing Whitey Duvall to have a seizure because he yelled at him, saying that he was a technical foul, Adolf decides that if he can't have Ed's Sauce, no one can. That night, he and his cohorts sneak into Good Burger and spike Ed's Sauce with shark poison when Trimmy Neutron and Otis, the elderly employee at Good Burger, catches them in the act. Adolf explains that his shark poison will put Good Burger out of business once several customers get food poisoning by the next day so that Mondo Burger will be the sole burger joint in town. He then has them admitted to the asylum as well.

However, RiceGum, Jesus, Otis, and Trimmy Neutron manage to escape Demented Hills and warn the staff of Good Burger about Adolf's intentions. RiceGum and Jesus then head over to Mondo Burger to get a hold of one of Adolf's Triampathol canisters, planning to turn it over to the authorities. While RiceGum distracts Adolf and his goons, Jesus sneaks over to grab a Triampathol canister. As Jesus reaches for a can, he accidentally knocks one over and it falls in the meat vat, spilling the illegal chemical into it. This gives him an idea. He then grabs all the cans and purposefully pours all of the Triampathol into Mondo Burger's meat supply.

As Adolf corners RiceGum and Jesus, the latter smugly reveals he poured all the chemical into the vat, causing the burgers as they go through the grill to grow enormous and explode. This causes the restaurant to shake violently, and the customers and staff flee from the scene. Adolf, Troy and Griffin try to shut down the grill, but one of the enormous burgers explodes in their faces causing them to flee with others while the restaurant undergoes extreme damage as it collapses.

The scene then attracts a number of policemen and firemen, where they find the Triampathol induced in the remaining Mondo burgers, thus exposing Adolf of his true colors. Adolf is arrested while Troy and Griffin are questioned by other policemen. After Jesus and RiceGum confessed of Adolf's use of the illegal food additives to make the burgers big and beefy, Adolf yells that they are lying, desperately trying to save face but the officers already found the remaining Triampathol canisters, knowing too much now that Adolf is the real good for nothing heartless liar, so they take Adolf to jail. As the cops lead a humiliated Adolf away and place him in the back of a police car, RiceGum and Jesus taunt him and yell "Hey, hey, remember: when you mess with Good Burger... YOU go in the grinder!" Thus with Mondo Burger shut down, Jesus and RiceGum are praised as heroes for saving Good Burger.

Trivia

 * Adolf was supposed to play a character with a different name, but the character was so much like him in real life during World War II, they decided that he should play himself in the role.
 * In recent years, digital releases of Undertale have Adolf digitally edited out and swapped with Jan Schweiterman, due to cancel culture.
