|Underfist: Halloween Bash|
|Season||Special / Pilot Episode|
|Cartoon Network US Premiere||October 12, 2008|
Underfist: Halloween Bash (shortened to Underfist) is a spin-off special of The Grim Adventures of Billy & Mandy. It aired on October 12, 2008. The special was going to be the setup for a new series, but the contract of Maxwell Atoms with Cartoon Network expired and the special was the finale of the franchise.
On Halloween night, Irwin, Billy, Mandy and Grim are trick-or-treating. Billy, Mandy and Grim decide to go home after having no success with Dracula, who rudely hands them pennies. Irwin realizes that his life is passing him by. Mindy (secretly turned into a witch by an evil marshmallow bunny named Bun Bun) fools Irwin into opening an Underworld portal releasing an army of evil candy warriors and Bun Bun, where they start terrorizing the neighborhood. Irwin gets attacked and contacts Hoss Delgado, who helps him with the battle. The warriors take down Hoss with soda-candy guns, which if Hoss gets sticky, he gets a rash. When they kill Skarr's winning purple pansies, he comes out of his garage with a robot, joining the battle. Soon it's an all out war, with no mercy, no rules, no nothing. Mindy again tricks Irwin, but this time, pretending she is being kidnapped by Bun Bun, taking her into the Underworld.
When the candy level gets to high, Hoss clicks his car unlock system, which a giant saw car (spoof of the Gotengo from Godzilla: Final Wars) comes drills out of the ground. They escape and start to plot their attack to the Underworld.
Soon they find a portal to the Underworld in the rain, which Hoss and Irwin jump in first (because he does not trust monsters and says to Skarr that he doesn't trust one eyed weirdos), but the portal turns off, because it is controlled by a diamond, which Mindy (in her witch form) smashes. The candy warriors try to sacrifice Hoss, by pushing him into hot coco, but they want to leave Irwin alive. This is because he has the powers of a mummy, which they need to keep the balance of the Underworld in place, and to become stronger warriors to eat the trick-or-treaters.
Mindy creates a potion which turns all the warriors into candy monsters, and all she needs now is Irwin's powers to create the candy warriors ultimate monster form. But Irwin refuses.
Soon Jeff, Fred, and Skarr find out a way how to get to the Underworld by using Hoss's car to drill into the Underworld, and they rescue Irwin and Hoss.
But the army of candy monsters hasn't given up yet. They head to the city and attack. Irwin and Hoss get into an argument, leading into a battle, turning on each other. While the battle is going on, the monsters suck up Irwin's power (but not all of it) and transform into one giant candy monster. Jeff and Fred try to escape, but they fail. Soon Hoss and Irwin see the monster and start to fight it, beating it. Irwin discovers that Hoss is scared of monsters, because he was haunted as a kid.
Soon Bun Bun admits his history. He cut off Fred's tusks, he made Billy scared of spiders, he haunted Hoss's childhood, and turned Mindy into a witch. Skarr joins Bun Bun's team (but not really) and kicks Bun Bun into hot coco, melting the marshmallow bunny.
Soon Underfist gets an award for saving Halloween that year, but they hear something outside and investigate. It's soon revealed that there is an army of squid warriors who have found their way to the surface world that the team made while trying to escape from the Underworld.

- When Hoss comes out of his trailer, he punches Perkins's face off, but later Perkins is fine.
- He also has a different voice actor.
- It might just be a different candy soldier.
- Hoss is stated to be 48 instead of 33. Although it could be due to a time skip between Grim Adventures and Underfist, it's unlikely as no one else has aged. Or Hoss possibly lied about his true age.
- Chowder and Courage the Cowardly Dog made a cameo on a Halloween float
- Thromnambular makes a cameo in Grim's lab but with 13 wishes not 9.
- This is technically the series finale for The Grim Adventures of Billy & Mandy.
- This special was also the pilot for the planned Underfist series, but due to Maxwell Atoms' contract with Cartoon Network ended around the time of the special's premiere, as well as Cartoon Network wanting more live action shows than animated shows at the time, the plans for the rest of the series was cancelled.
- Fred was redesigned to a peanut size. He is more green, smaller, and has a higher-pitched voice.
- Chowder makes a brief appearance in the film in a pumpkin when Hoss Delgado is seen looking around Endsville.
- There were supposed to be more sequels shown at the ending credits of Underfist: Halloween Bash. The sequels in order are "Underfist Vs. the Dinosaurs", "Underfist Against the Astro-Vampires", "Underfist: Easter Beatdown", "Underfist: Return of the Spider Queen", "Underfist: C.S.I. Miami", "Underfist Teaches Traffic Safety", and "Underfist Babies". However, none have ever been produced.
- Maxwell Atoms has stated that some of the sequels were simply jokes, but that at least the first two were actually planned.
- General Skarr seems to show signs of aging, as he now has a beard, mustache, and his military clothes are absent in the film (he's either in his underwear or in his Underfist uniform).
- Additionally, Hoss has also aged: he has grey streaks in his hair, he's put on weight, and it's confirmed that he's 48 years old in the movie (as opposed to being in his thirties in the series).
- Baron Von Ghoulish, from the episode "Billy and Mandy Save Christmas", makes a brief cameo in the film. He is seen being scared by Trick-or-Treaters in costumes, and falls back into his coffin.
- We learn how Hoss lost his hand, leg, and eye; he explains the he was running with scissors, despite what his mother told him.
- The science clothes Billy is wearing look similar to Dexter's clothes from Dexter's Laboratory.
- The characters who make up Underfist are all secondary characters who started gaining popularity after appearing in the series (sometimes called "Ensemble Darkhorses"). This is most likely why they were chosen as the main characters and Grim, Billy, and Mandy, are secondary characters this time.
- Irwin was, arguably, the most popular of these characters, and played a more significant role in later episodes of the series. This is probably why he is the main protagonist.
