Personality: While he is the personification of death, he is easily tricked and trolled. He is also very sensitive to being called a "bonehead." Laughs at the misfortunes of others, but definitely has a soft spot which is shown...surprisingly often. He speaks with a Jamaican accent.
Inventory: The Reaper's Scythe, which he is largely dependent upon. Grim is also in possession of a Magical Trunk, larger on the inside than it is on the outside, Grim stores a menagerie of sinister, evil, and, more importantly, dangerous magical objects for safekeeping.  Grim's Black Robe is also magical, aside from being able to expand along with him whenever he shapeshifts, Grim's robe has been seen as sustaining damage and then seen again intact

Abilities and skills:As a supernatural creature of the Underworld, Grim naturally has tremendously powerful supernatural powers of his own, such as being able to grow in size and warp his form and the ability to possess the living, (as seen in Get Out of My Head). As an 'undead, talking magical skeleton', Grim is a complete animated skeleton of bones that is able to function both as a complete skeleton or independently as individual bones. Grim has also been seen creating flames whenever his tempers flares, even his eyes will shoot out flames when he gets angry or determined. It has also been seen that Grim has telekinesis.

Beyond this, Grim has demonstrated the use of spells in earlier episodes; consulting with Underworld editions of books and manuals of magic, (such as in Tickle Me Mandy when Mandy went away for a day, Grim used some of Billy's toys to make a 'Mandy-Substitute' to keep Billy company). Grim owns copies of Underworld tomes seen in various episodes.

Other: There are, in fact, multiple Reapers, and Grim has been freed from his enslavement to Billy and Mandy, at least temporarily, to take on another assignment. Remember how Jesse's CS mentions the Reaper? That one is going on vacation and Grim is filling the role for a while. Unlike the other reaper, everyone can see Grim.
