All the characters in the Fallout universe are pretty interesting. I like Veronica. Also I laughed so hard when I first found FISTO in the game. lol

Caeser has some of the best lines and backstory in the game. I couldn't help but keep listening to his wisdom and history and beliefs.

I like lieutenant Carry Boyd because she doesn't put up with [censored] people like the quarter master guy, those kind of people who ruin everything for everybody els just for there own selfish things.
I like Sunny smiles just because reasons.
I like boxcart because of his colorful dialog.

Dude, have you met the Toaster that will end all life on the planet?

So far, Cass - I love some of her lines. "What are you doing here?" (Me) "Just looking around.". She says "well keep those eyes up and turning or I'll set them spinning".

Red Lucy. Am I the only one who loves her?

I don't see the fasination with her.
She's a bit of a [censored].
She wants eggs.
She gets impressed I can do a farmers job.
She [censored]s me.
She knows how to use a light switch.....

.....SHE'S GOLD

The survivalist is the most bad ass character in the game, seconded by Daisy Withman.
