All the taunting quotes:

Feel free to add If I missed any

And reply with your favourite one!

A son of Guilliman knows only war!

Beg your gods for mercy, I have none

Bolter and sword!

Breathe your last

By the Golden Throne

Death to the foes of Macragge

Die!

Emperor be praised!

For Terra and the Emperor!

For the Emperor!

For the honor of Ultramar!

For the Imperium

For Ultramar!

Forget nothing, forgive no one

Glory for Ultramar!

Glory to mankind!

Hail to the Emperor, heretic!

I am an angel of death

I am an executioner of the Emperor

I am cleansed in the blood of my enemies

I am hate incarnate!

I am proud to serve, and proud to die

I am the edge of this blade

I am the Emperor's weapon!

I am the point of his spear

I am the wrath of the God Emperor

I am your doom!

I care not if this planet stands, so long as you die!

I know no fear!

I purge, again!

I send you to meet your foul god

I smell demon filth

I'll cast your soul into the warp

I'll smash them to pieces

I will finish the work Captain Titus started

I will make my brothers proud!

I will purge them for the Imperium!

I will slay you

I will unmake you

I will wade through the blood of our enemies

In his name!

In the Emperor's name!

It is I, Malum Caedo

Mine is the work of the righteous

My armor is contempt

My love for the Imperium is matched only by my hatred for the heretic

My shield is disgust

My sword is hatred

No enemy of the Emperor escapes unpunished

None can stand against our hatred

None can stand against the might of the Imperium

None will survive!

Purge the unclean

Rejoice, your salvation is here

Scour the stars of the heretic

Sidonus laid down his life for this planet! I protect his sacrifice!

Stamp them into the dirt

Suffer not the heretics to live

The blood of martyrs is the seed of the Imperium

The Emperor demands your life

The Emperor guides my sword

The Emperor protects

The Emperor sent me to redeem you. In holy fire!

The Emperor's hand will touch you and you will not survive

The Emperor's will be done

The enemies of the Imperium will taste death this day!

The guilty shall be punished

There’ll be nothing left of you

Traitor scum

Triumph or oblivion

Vengeance has come for you

Whilst I draw breath, I stand. Whilst I stand, I fight. Whilst I fight, I prevail.

You die here, vermin

You will drown in your own blood

Your death is my glory
