Grim

The Grim Reaper is a character from The NEW Grim Edventures of Ed, Edd n Eddy, which is a crossover between Ed, Edd n Eddy and The Grim Adventures of Billy & Mandy (often shorted to Grim Adventuers or Billy & Mandy).

Personality
Despite Grim being, well, the Grim Reaper, he is shown to enjoy things mortals might, such as coffee or automobiles. He is usually quite serious, but can also do comedic things, (usually because of something the Eds do). He is in later chapters a broken down man, because of the Eds' problem-causing nature.

Grim is also a bit competitive, as he accepted Eddy's challenge to a game of "Yo Mama" joke-telling. It will be revealed in later chapters that Grim has been this way for quite some time.

He's also a man of his word, as he continues to be "best friends" with the Eds despite hating them. He also promised Jack eternal life, and kept his promise.

Supernatural Powers
Grim, being the Grim Reaper, has several magical powers; though, almost all of these powers come from his scythe, so he is almost defenseless without said scythe. Grim always seems to have some sort of new power. These powers include, but are not limited to, shooting lasers from his scythe, controlling someone's mind, magically fixing something with his scythe, giving someone superpowers, playing guitar so well that the neighborhood burns down, summoning mystical creatures, and most importantnly, creating a vortex to other realms with his scythe.

History
Grim had a rather cruel mother, and a neglectful father. He was often bullied by other creatures in school and elsewhere, until one day he won the election to become the Grim Reaper. Grim remained a large celebrity in the underworld, until one day, he lost a bet to three mortal beings named Ed, Edd n Eddy, making him the laughing stock of the underworld.

Trivia

 * Despite Grim being a skeleton, he is able to do normal things, like drink coffee or eat mortal food.
 * Grim's age is always a mystery.  He might claim his scythe to be two thousand years old, yet when he was a teenager in the Earth's Prehistoric times, he was given a prototype scythe.  It could be possible that not even Grim knows how old he is, because he is immortal and could easily loose track of years.
