Mine is easily Mr House dude reminds of tony Starks dad so much...I do feel like he could've been written a lil bit better tho at the same time it's probably hard to write a character who is leaps and bounds more intelligent than everyone else

I agree, mr. House has a lot of character.

Again with the tough questions. John Cassidy is quite awesome, and well Rose of Sharon Cassidy then goes without saying. Owyn Lyons is interesting because of his different look at how the Brotherhood could function in society, which makes his downfall all the more tragic. I would probably pick one from each game, as its much easier.

I'd have to go with Joshua Graham. A tough-to-kill Man of God with a history that is both twisted and tragic, I really liked both his character and his story.

Come on guys, you know that nothing beats this suit

in bethesda's fallout, the tunnel snakes

in black isle/obsidian's fallout, boone

The character I was excited most to meet was President Eden, and got even more excited when I learned he was an AI. He's not really "cool" though.

I have to say Boone,

Weird story, I had a squad leader named Boone, playing NV got weird after that.

I'm boring. Mine are a toss up between Moira (FO3) and Veronica (NV), with Veronica first by just a smidgeon

Lots of good NPCs I enjoy speaking with in both of those games, though

Many of the characters of New Vegas take the cake, and its hard to really choose between which one I liked the most. Mr. House, Caesar, Joshua Graham, Elijah, every character from Dead Money, basically all of the companions.

Harold.

Top ones are (random sequence)

Harold (''Don't know, didn't live!'')

The Master

Mr. House

Arcade Gannon

The whole Think Tank

Raul THE GHOUL

Frank Horrigan

There are probably more. Yes, I know, they're too many. But the series is full of so many good characters.

Dude, just one?! This is tough.

Fallout 1- The Master (DUHHHHH).

Fallout 2- Frank Horrigan, John Cassidy, Marcus, Tandi (I like seeing who she's become since F1), Goris, The Brigde Keeper (I laugh every single time I ran into him).

Fallout 3- John Henery Eden, Augustus Autumn, Liberty Prime (DEMOCRACY IS NON-NEGOTIABLE!).

Fallout NV- Cass, Boone, Veronica, Mr House, Vera Keys, Father Elijah, Joshua Graham, Randall Clark, Caesar, ED-E, Yes man.

Fallout 4-

Three-dog

Pff just one is impossible lol. Let's list some candidates first:

Cait

Dean Domino

Father Elijah

Robert House

Butch DeLoria

Joshua Graham

John Henry Eden

Veronica Santangelo

Caesar

Christine Royce

Nick Valentine

Ok I think those are my favorites. If I have to pick one I'd probably say Butch DeLoria. Guy was the definition of cool.

Fallout 1: Killian Darkwater

Fallout 2: Cassidy

Fallout 3: Ashur

Fallout: New Vegas: Rose of Sharon Cassidy

Fallout 4: Cait and Deacon

If "coolest" is the descriptor, then it is Boone. Hands down.

He is like the Fonz of the Fallout Universe.

with that avatar, how you can not vote for the King? =p

I forgot one- The best of the best, https://www.youtube.com/watch?v=EkKkHmFOfKE

Raul the Ghoul as well, boss.

Oh no question here... and I know a lot of you people that know me here will groan and roll your eyes... Ulysses!!! Oh and yes, Joshua Graham was an epic, awesome NPC as well!

I liked Cass, too in Fallout NV, I could totally see me hang out with her in RL.

Meet Cait in FO 4 yesterday and just love her Scottish Accent, I'm sure she will be a hoot to travel with. Paladin Danse is very impressive and I can't wait to learn more about him.

Also, don't forget Goris from Fallout 2... nobody could wear a trench coat like that Deathclaw!! He was just too cool!

Deadeye Ricky from Honest Hearts. The guy grew up in Vault Two-Two, owns a Pitboy, killed a Brotherhood of Steel Paladin by shooting him through the eyeslit of his helmet with his 11mm machine gun, he's killed four Deathjaws. I dare you to name a cooler character.

Dornan.

Ricky may have done all that stuff but god help him if Dornan ever catches him out of uniform.

Not sure if he qualifies as "coolest", but Killian Darkwater is the NPC that I remember most. He was the first real exposure I had to what Fallout was all about, and served as an abject lesson in "reroll a character with some social skills, you stupid D&D-addled combat monkey".

Honorable mention goes to Christine Royce. Again, once I got to talk to her with a character who wasn't a social orangutan (this time knowing full well what that means in a Fallout game) she was one of the deeper and more interesting characters in New Vegas.

How about punching?!? It's the gift that keeps on giving!

I do have a soft spot for Veronica. She's like the overeager pet chipmunk I never had.

Fallout 1: The Master, Harold, and Lou

Fallout 2: Frank 'punch a deathclaw in half' Horrigan, Goris.

Fallout 3: President Eden, Fawkes.

Fallout New Vegas: Mr. House, Caesar, Ulysses, and Legate 'The Monster of the east' Lanius

Fallout 4: Kl-e-o

Fallout 1: Harold
Fallout 2: Harold
Fallout 3: Harold

Not that there aren't other cool characters, just ... Harold is really one of a kind.
