Billy & Mandy's Big Boogey Adventure

A scene of Endsville two weeks into the future shows a dystopian world ruled by the "Lord of Horror", who wields the all-powerful artifact known as "Horror's Hand". At the same time, two robotic replicas of Billy and Mandy are sent into the past, to stop the real Billy and Mandy from interfering with the current events. In the present, Grim goes to reap General Skarr, who accidentally got a big wound in his torso. However, due to Billy and Mandy's meddling, Skarr escapes, and they make a big mess in the city. Following his failure to be an effective Reaper, Grim is taken to the Underworld Court, presided by Judge Roy Spleen, where he is sued for misuse of his powers by his nemesis, the Boogeyman. After the trial, Grim is found guilty, is stripped of his rank and magical scythe, and he, Billy, Mandy, and Irwin are sentenced to be exiled. Then, Boogey volunteers to carry on the sentence by taking the prisoners aboard his ship, and dropping them off in a river of fire; he plans to do this while he sails to obtain Horror's Hand, an object capable of transforming him into the scariest and most powerful being in existence. The group of Billy, Mandy, Irwin, and the powerless Grim, escapes from Boogey's ship, and set themselves to reach Horror's Hand before Boogey does. They eventually meet Horror, the guardian of the Hand, at the same time Boogey and his crew arrive. Then, in order to decide who will have the honour to battle Horror for his Hand, the heroes and Boogey participate in a challenging obstacle course, which the heroes win against all odds. After dispatching Horror with ease, Billy, Mandy and Irwin reach for the Hand, but it defends itself by making their worst nightmares come to life. Then, Boogey gets ahold of Horror's Hand, but he turns out to be the least scaring creature ever, seriously injuring himself, and being abandoned by his own crew. Then, Grim recovers Horror's Hand, and at the same time his sentence is revoked, becoming the Reaper once again

Billy & Mandy: Wrath of the Spider Queen

On a rainy day, several giant spiders appear in Billy and Mandy's school and start kidnapping the children one by one. Grim presumes this is somehow related to his past, but doesn't figure it out until he receives a message saying that Velma, the Spider Queen, an old friend from high school, is responsible for it. Meanwhile, Billy meets with his "son", Jeff the Spider, who informs him that he is precisely marrying Velma. After trying to recover a talking carton of chocolate milk from Jeff, Billy and Jeff get into a fight, and Jeff looks angrier than ever before. Upon meeting in the school's football field, Velma tells Grim that she has finally come to devour his skull and absorb his powers, since one hundred thousand years ago Grim cheated and robbed her from the possibility of becoming the Reaper. Converting the school into her own palace, and with help from the Dark Elves, Velma captures Mandy, Mindy, and Grim, and proceeds to devour the latter's skull. However, when Velma cracks open Grim's skull, his thoughts start coming out, and she is able to see his memories. In the following, Grim's skull is connected to a screen, and the story on how he became the Reaper is shown. It is revealed that an election was held in the Underworld's high school to choose the Reaper, in which students had to vote on the scariest participant. Velma was the scariest contester and she was getting most of the votes over the pathetic Grim and the Boogeyman. Then, Boogey decided to tamper with the ballots, and Grim in turn decided to help Velma, but she got the impression that Grim was the cheater and ran away. Then, in a fit of anger, Grim used the prototype scythe in a spectacular fashion to scare Boogey off. In consequence, the people that hadn't yet cast their vote, voted for Grim, who thus became the new Reaper. While the story is being told, Mandy and Mindy form a temporary alliance to fight the spiders, and also Billy reconciles with Jeff, and fights the spider-cow centaur-li

Mandy takes over the KND by fooling Numbah 363 and the rest of the KND, but Numbah 5 knows she's not Numabh 1, but is taken to the med lab.
