A False Character

Humans personify Death.
The clothes and accessories
Vary widely by culture
And technology, but bones,
Often a full skeleton
Lacking any flesh but whole,
Articulated, are stock.

Death is usually a male,
Usually dressed for a task.
Sometimes Death is humorous.
Sometimes Death rattles, speechless.
How on Earth could this be Death?
Why would angels take his place?
How does Death land speaking parts?
