For the starting legions I would say El ' Lion but if you ask me about any other legions.. * in dreadnought voice HANDS DOWN MY BELOVED PRIMARCH FERRUS MANUS!!!!*
If ever there were a primarch you did not want to meet in a dark alley the wolf would disembowel you before you could shit yourself
Cus he looks like a inner city crack head? all the more reason for the wolf to show up and clean out the trash. Russ the hardest working wolf lord in the empire.
Hard working and air-headed. Still don't like the wolves for what they did to the TS. As for Curze, I think he's like the Punisher of 40k. Some people compare him to Batman, but I figure since Batman doesn't kill...
I can see Punisher of 40K I will give you that. but batman of 40K ummm hands down that would be the savior of deliverance the one and only Corax of the raven guard. tries to save everyone with "minimal" casualties (yes this is war not simple crime fighting) and has a way of coming back time and time again
Spoilers inc, AVOID - AVOID - AVOID! In the Horus Heresy novel 'Fear to Tread' Sanguinus has 3 visions of the siege, one of which is Horus choking and killing him. He knew as soon as he stepped upon the ship his fate was tied, he fully went down that path knowing that his sacrifice would save the Imperium that day. I don't think he over or under thought it, duty and loyalty is all you have left in a time of betrayal and heresy.
To be fair Ollianus Pius was the one whose sacrifice saved the Imperium...the Emperor sort of didn't really care that much that Sang died....for some reason.
