I had an idea for a riddle yesterday. Here it is.
I am a horned and hooded figured, bearing a shield and blades.
The ability to control great power is in my clutch.
If you find yourself under my boot, you will discover that I am exhausted.
If I am not tired, then my boot may spare you.
You can easily choke me to death.
Does this shock you? I am shocked, too.
What am I? (and why?)
