Who am I?

Who am I you may ask
I am an angel
A blessing in disguise
I am the one who pulled you from hell

I have no filter for the words I speak
I am brutally honest
And can’t think on my feet
I was sent from heaven above
To rescue the world you all grew to love

I am dashing and smart
Yet am stupid at times
So have you figured it out
Who I am from these rhymes?

If not that’s okay
I have more clues to give
I have to protect them both
Make sure they continue to live

In the beginning
It was just a job
now I can’t imagine life without them
even though they sometimes think I’m a knob

travelling around
in the blink of an eye
although I do sometimes enjoy the road trip
this is cannot lie

We go looking for trouble
To fight off the bad
From vampires and demons
To get revenge for their mom and dad

Black eyes or yellow eyes
Sometimes even red
We don’t care who they are
They all end up dead

Who I am or what I do
now do you know
Do you understand yet
or have you guessed the show?

PS. No guessing Craig!!! you already know haha and no hints to people!
