Death

Appearance
In his wolf form (Grim), Death looks well... like a wolf. He has black fur and blue eyes in that form. In his regular form, he has a white skull for a face and a black body.

Personality
Grim was very tricky and chaotic. He tried to murder Kate many times, and earned the trust of Glitter, Kate, and even Blaze, though not all of it was a trick. He didn't want to cause Kate pain when and if he murdered her, and showed compassion and pity for the ogres, killing all of their zombies because he knew they were hard to maintain.

Kate
Kate had started to trust Grim, even though he had tried to murder her countless times. Grim earned a little bit of compassion for Kate, but since she was Providence and he was Death, he felt he had to kill her, so he wouldn't die.

Pestilence
The Horsemen all had their turn to reign terror on the world except Death (and Kate, but she was young and didn't even know she was a horseman yet). This is because Death made a deal with Pestilence that he could keep reigning terror on the world and infecting people. Death wouldn't interfere. The apocalypse was suspended only to cause more pain.

Episode Three
In this episode, Glitter is shown walking past a bunch of cars that are tilted taking up lanes, and not in a correct position. She is dripping blood from her mouth. Kate tells her that zombies were going to find her trail of blood 'magically delicious', and Glitter argues back that she doesn't think zombies are very good at tracking. Then you hear Grim's howl, and Kate asks 'how about wolves?'. Glitter decides that they should find a space to stay for the night, and puts Kate in a car. Kate wants to help Glitter fend of wolves (if they come), but Glitter forces Kate to stay in the car. Then glitter faints, and you see a flashback to when she was young. There was a little girl in a garden holding up a flower, with two adults (probably her parents) sitting on a bench watching her. The little girl sniffs the flower, and then we see a unicorn who I think is commander telling Glitter that they should go as Glitter happily watches. A butterfly flies by, and the girl catches it... buts it's not a regular butterfly. It's a DEATH BUTTERFLY. It turned the girl into a zombie, and Glitter shouts 'NO!' as it charges at her. Then, Glitter wakes up to see Grim in front of her, and Kate shouting for her to open the door. Grim tells glitter that she's in the way and that the girl is his, but Glitter refuses. Grim attacks her, and you see Glitter lying down with a huge splotch of blood on her, and the car, while Grim claws at the door. Blaze comes to the rescue, lifting up Grim with his magic, and telling Grim to get away from her, flinging him far into the forest.
