Fear

You have nothing to fear but Fear itself. :)

[Mandatory AU: Fear is said to have blood manipulation powers and uses it to coat his scent. This sometimes works as a disadvantage as its victims are aware of his presence with the smell alerting them ahead of time. But it can also help as it can leave his prey still in fear as it awaits its fate. 

Fear created its skull artifact using Death's magic to enhance his power and master blood-bending spells. It's said anyone who touches the skull will instantly die.]
