List of Grim & Evil characters

Billy

William "Billy" is a human boy with a profound intellectual disability, having been outperformed by a shovel and two candy bracelets on an IQ test, though he acts like a smart-aleck. Mandy is Billy's best friend, though she treats him more like a servant than a friend. It has been hinted several times that Billy may have underlying feelings for Mandy that he not fully realize. Billy is far kinder to Grim than Mandy is; while he almost always goes against Grim's advice and uses him as a plaything, he appears to genuinely like him and often tells Grim that he is his "best friend".

Due to Billy's foolish desires, which he orders Grim to bring about, he is often the cause of Grim and Mandy's mishaps. Although good-natured, he has occasional fits of stubbornness and rage, which shows insanity that even Mandy seems to fear. Billy is also scared of clowns and spiders, resulting from a childhood incident where Bun-Bun snuck into his room and tormented him with spiders.

Mandy

Amanda "Mandy" is a human girl with a sinister, manipulative nature despite her appearance. Mandy has been known to domineer everybody around her without fear, and the few things that she likes include junk food, television, and all things dark and melancholy. She also possesses a strong lust for power as revealed in an episode providing insight to the future of the town of Endsville, in which Mandy has enslaved all of its citizens and evolved herself into a large caterpillar-like creature. In Underfist: Halloween Bash, after the Underworld invades Earth, Mandy seizes power as the new President of the United States, with Grim and Billy serving as her weapons experts, the trio rewarding Underfist for saving the world.

Throughout the series, Mandy rarely smiles, and her facial expression remains perpetually disgruntled. Mandy smiling is shown to be the end of the world; in the episode "My Fair Mandy", all of reality is distorted, resulting in the series swapping premises with that of The Powerpuff Girls, another Cartoon Network animated series.

The Grim Reaper

Evergrimskull "Grim" Death a.k.a. the Grim Reaper is the personification of death appearing as a skeleton wearing a black, hooded cloak and armed with a scythe, who serves as a psychopomp between the realms of the living and the deceased. Grim was born around 137,000 years ago at the time of the Stone Age and speaks with a Jamaican accent. The continuity of how Grim gained his status and powers varies between episode. In the television film Wrath of the Spider Queen, Grim was elected to his position as the Grim Reaper while in middle school; in "A Grim Prophecy", it is shown that he has been the Grim Reaper since childhood. His long scythe is the source of nearly all his supernatural abilities, and possesses many magical capabilities and qualities; although he is still capable of using some incredibly powerful magic spells without it, these instances are quite rare.

After losing a limbo contest to Billy and Mandy after they cheated, Grim is fated to be their "best friend" forever. A contract legally binds him to them, such that if he were to ever break his friendship with them prematurely, he would be forced to spend eternity in a jail in the underworld. as a result of violating his contract. Despite this however, he has often tried various ways to get out of this servitude. Though Billy is friendly towards him, Mandy treats him dominantly, and this angers and irritates him to the point where he constantly fantasizes about killing both of them. However, there have been instances that show that he does indeed care for them. His adaptation to daily life also leads him to neglect his duties as a Master of the Underworld and, eventually, not even care about who uses his scythe.

Irwin Dracula

Irwin, later Irwin Dracula, is a nerdy boy and a close friend of Billy's. Unlike Mandy and Billy, who show no signs of fear for the frightening, supernatural and magical beings and settings around them when using Grim's magic to venture into the underworld, Irwin has displayed more signs of cowardice in such situations and seems to be more easily terrified than his friends when he accompanies them on such trips. Irwin's mother and maternal grandfather are mummies, while his paternal grandfather is Dracula.

In rare instances Irwin is shown to have an evil, darker and power-hungry side to his personality. In the episode "Heartburn", Mandy discovers everyone's true heart through the use of Grim's special camera, but is greatly shocked when she discovers that one side of Irwin's heart looks like hers in a creepy way. Irwin explains that he was born evil, but had a change of heart when his father showed him the meaning of respect, friendship, and love.

Billy's family

• Harold (voiced by Richard Steven Horvitz) is Billy's equally dimwitted and idiotic father.

Despite his low IQ, Harold was accepted in Harvard and is a former Navy Seal.
• Gladys (voiced by Jennifer Hale) is Billy's mother. She is a loving, tolerant, and patient, yet mentally unstable woman. This is brought on by having to deal with her family, and Grim as a guest. She has a severe facial tic, which usually appears when Billy is misbehaving, when her authority is challenged, or whenever Grim is present, and has also developed nervous breakdowns. Despite so, Gladys cares deeply for Billy and Harold, although when Harold gets fired for doing something so stupid or whenever Billy is really disobeying her or acting up, she does have large outbursts of rage.
• Milkshakes (voiced by Grey DeLisle) is Billy's cat. In spite of his lack of significance in the series, on a couple of occasions he has played a key role; his body has been overtaken supernaturally on two occasions in the past; once by a bookworm to help Billy in school and on the other instance by an enraged, vindictive Mandy, whose body had been possessed by a clowning Billy earlier in the episode.

Like his father, he has the power to shapeshift and most of the time he appears in the form of a child.

Irwin's father insists that their unusual pairing leaves "a lot of questions that don't need to be answered".
• Judith "Judy" Lockin' Dracula is Irwin's mummy mother and wife of human/vampire Richard Dracula. Since Judy is undead, she lives in the basement (resembling an Egyptian basement).
• Tanya "Grand-mama" Dracula (voiced by Phil LaMarr) is Dick's mother, Judy's mother-in-law and Irwin's paternal grandmother. Despite her angry demeanor, she seems to care for Irwin, but will sometimes embarrass him. In "Dracula Must Die!", it is revealed that when she was young, Tanya was a very lovely young woman who could really kick-butt with karate and that she married Dracula because he was a great dancer despite him being a vampire.
• Lord Dracula (voiced by Phil LaMarr) is a vampire, Irwin's paternal grandfather, and Grim's childhood hero. When he danced for Tanya she instantly fell in love with him, but he ran away from her when she beat him up, thinking he was a bat. Dracula's appearance and mannerisms are patterned after the blaxploitation films of the early 70's, most notably Blacula, as well as Fred G. Sanford of Sanford & Son.
