This is in fact the second rendition of the song. This one is inspired by HK-47 and IG-88. The other version is not here because it's about a character from a different series.
Screaming terror all around
When he moves, that metal sound
Electronic glowing eyes
He's arrived to mortify
Body formed from wicked steel
Mind fine-tuned, you know it's real
There is no way for you to tell
Who he's here to send to hell
Standing tall through time and space
Hunting down members of your race
Sees no humor and fails no test
He his here to lay your soul to rest
Soul to rest
All the way from judgement day
To the dawning of your wicked ways
Threads of your mind begin to fray
It's All Assassins' Day
I love the way he gives you a fright
How those mechanical fingers grip tight
He's here to send you to the other side
Don't waste his time and put up a fight
The hunter killer brings you the end
He doesn't care about your crimes
Has no allies and has no friends
And never fears the future day he'll die
He will die
All the way from judgement day
To the dawning of your wicked ways
Threads of your mind start to decay
It's All Assassins' Day
It's All Assassins' Day
The bounty hunter bringing your death
Contains a bloodlust for evisceration
Obliterating all your final breath
Looking forward to exsanguination
All the way from judgement day
To the dawning of your wicked ways
Threads of your mind start to decay
It's the end of your days
No one left to keep the wolves at bay
Open your skin, let your blood astray
You know the price and now it's time to pay
It's All Assassins...
It's All Assassins' Day
