Joshua Graham is not a complete stranger to any Courier. Legion characters know him only as the Burned Man, the disgraced, almost mythical ex-Legate who cost them victory at Hoover Dam in 2277, the first (and only) real defeat the Legion has suffered since its founding by Caesar. You can talk about him with Caesar, Lanius, Lucius, Vulpes and the slave Siri (who describes him as a 'vengeful spirit').

To the NCR Courier, he is the former head of Caesar's military forces who blundered when attacking Hoover Dam, falling for the Chief's trap in Boulder City (although the Legion's aggression still resulted in a bloody battle, as evidenced by the memorial). Even in the NCR he is near-mythical, as many NCR Rangers/Snipers have reported killing him. You can chat with the Chief about him, who says that it's not 'clear cut' whether he's dead or not.

Even Independent/House Couriers know his name as a part of history, given the importance of the First Battle of Hoover Dam (and its continued importance - the game ends there for a reason).

We haven't met him, but we know him by his deeds and reputation.

Basically, he's a big sodding deal.

He survived being thrown over hover damn on fire so i dont think a bullet to the brain will do much to him.

Nitpick; The Grand Canyon, not Hoover Dam. Besides, if he bleeds, we can kill him.

If hes nice he will live
If not ill shall set him alight with a flame thrower

He helped found the legion. So he will die for his past sins

God forgives your sins for vast amounts of bloodshed

Entirely depends on the context of Honest Hearts, I'd say, and which of my two characters I'm playing. I'll likely exhaust his dialogue thoroughly before making any decision.

depends, if i get morecool stuff if he gets killed then he shal die but if i get more cooler stuff he is alive, then he shal live, depends. :shrug:

he is only a commander, he did not help found the legion,

He sort of did.

I hope he has 6500HP and has a a form of the Monocyte Breeder.
