Need some assistance

So for my story I'm writing I need some help, Guy meets Girlfriends father, I've come up with three things that he could say, but I need help deciding

How these are said is an icy Malice overtone with a Russian Accent
Option 1:
If you ever intentionally hurt her, I'll have your balls on a silver platter.

Option 2:
You break her heart I'll break your legs

Option 3:(Courtesy of my friend Alex)
you break her heart, you'll be watching yours on a flagpole

Whell what kinda character is he? <_<

I'd suggest that the threats of violence comes later. Or that the boyfreind does something stupid at first, to make the father hate him.

Appearance wise he's 'A tall slender man with graying hair'

Personality wise, the back story is he's raised Valkyrie all alone since she was 3(I'll explain the back story later in the story). He's your normal protective father, the mayor of the town, and outwardly a kind man, He's also Russian.

Then I suggest giving him intimidating body language, but still be neutrally friendly with the boyfriend.

That is generally how I picture him but then when this is said the precursor is as follows.

'He turned and looked at me, the warmth drained from his eyes replaced with an Icy coldness and malice intent.'

Option 4.
if you hurt her,i promise i'll make you never see the sun rises for eternity.

I like the idea, but then how about altering it, to something like

If you hurt her, I'll make sure you never see the sun rise again.

If you hurt her, I will break you. (courtesy of Rocky)

I have a little motto. You fuck her, and my gun fucks you.
