I am faster than you can run,
so abandon me, go home and have fun.
I live where the moon rise from above,
so abandon me, get rid of the hands in glove.
I am soft like a kitty and hard like a rock,
without any warning we come in flock.
Who am I that you might ask?
a symbol of fear, hidden in a mask!
Hints:
Every line is a hint, there are no word plays and there are more than one references. Also, I bold and italic some lines for a reason~
Hint #2:
2 words from the first 2 lines gives you enough hints when combined with the lines
