Kind of a hard one, I would really enjoy removing a head of a Thousand Son, though punching the smirk off an Eldar face is always a good feeling, again ripping the beating heart from an Orks chest would satisfy me

You, i like you.

This man knows where it's at.

Killing Ultramarine with Eldar's dead body will be a great option for me

DEM ELDRAD... ELRAD... DRAL... DEM PINK SOFT SKINNY UNS, I LIKES DAT NOIZ DEM BONES MAKE WHEN DA TRUKK HITS EM LEGS ! WAAAGH !!!

Nothing shall bring greater pleasure in the game than to bring a heretic to his knees and to give them their reward for heresy, a blade.

Tyranids. there are so many ways they could go with this I almost came when i was reading the wiki

Maybe ripping off the bunny ears of Khorne Berzerkers. Thats above the average joy of annihilating the enemies of the Imperium.

Being one of many of the Emperors, and Sanguinius, warriors in this galaxy... I won't discriminate, I'll kill everyone equally...

I will slaughter every enemy of Imperium, especially orks

Orcs and Chaos Space Marines
