* Drakensis' Lovehammer stories focus on Angron. It would be tempting to say that all he does is a crowning moment of awesome, but let us settle for [[http://www.fanfiction.net/s/6662343/13/Lovehammer_Drakensis Chapter 13: Question of Identity VI]].
--> "This is how I refuse."
* The final fight between the Deamon Tazabdulog and [[http://www.fanfiction.net/s/6683021/8/Lovehammer_Winged_Knight Trygg]].
* Old man Ruith's introduction to the Imperium. Where he manages to piss off Mortarion, his Astartes, Sailor Morta, and several Imperial guard regiments as he runs around as a deliberate distraction. Oh and he steals a commissonar's hat for his own personal use in the process. AND manages to get away unscathed.
* The sheer epicness of the fight scene between Huron Blackheart and The Captain in ''The Scattering of Serenity''.
