This is Chaos, from the 'Journey on series'.
Chaos is ''The grim reaper in training'' as he puts it. However he opts for a hoodie instead of 'the hood'. Chaos, being a teenager, naturally pays more attention to other things, instead of his work. He first met Montell and Jack when their pet worm died, and Chaos came as their grim visitor.
Chaos has often been described as an emo. (which isn't suprising seeing as he is a walking skeleton.)
