Its true. I swear it. I just saved him from that virtual reality vault when I found out. I was going to fast travel to Rivet City, but.....I felt kinda uneasy about him so I decided to follow him. Something about him just didn't seem right. Out of nowhere a Death Claw attacked him. I was going to help him, but then I just couldn't stop thinking of how he abandoned me to deal with that psychopath overseer. Wait.... what's this? Dad is busting out a ........ crowbar? Really, a crowbar? Dad is supposed to be some super smart scientist & the best he can think of is a flippin' crowbar? He must be a masochist & like the pain. Dad falls down. I waste the Death Claw with my Harkness Plasma Gun. I go over to loot Dad's body, but what's this? Unconscious? Unconscious? He's not dead? I thought I saw that Death Claw dismember him. Wow, I guess not. Dad gets up. No blood & full health. I go to initiate dialougue with him & he just acts like nothing happened. Creepy.

Just a little further up the road 3 dogs attack Dad. He says something stupid like, "I didn't want it to come to this". Like the dogs were gonna understand what he's sayin'. Out comes the crowbar. Come on Dad, you can do better than that. Surely he can defeat three dogs. Nope they munch on his nuts until they see me with my Chinese Officer's Sword. One hack each & the dogs are dead. Once again Dad is not dead, just unconscious. What's it take to kill this guy?

Getting closer to Rivet City a giant Radscorpian attacks Dad. Once again same thing all over again.

I'm flippin' scared crappin' muh pants. Dad is an Immortal Masochist!!!!

Obviously, Dad is Gordon Freeman is disguise.

But... he doesn't have his glasses!

Hmm... maybe that's why he tried to crowbar a Deathclaw to death... he thought it was a Vortigaunt!

Or, his NPC is tagged as "essential" so that you won't fail the main quest if he dies.
You're amazed at him being invincible (not immortal) then you'll probably overdose in Skyrim, every 3rd NPC is an essential character and cannot be killed.

Haha. Nice Grouse. That made me chuckle this morning, thanks.

And yet this bastard sends his only son into the purifier to clean it out because "he's not a fighter", yeah right you jerk.

Dad has a feign death perk.

I cant remember exactly wahat happend ... but I did that too after that place.

Which is a new thing Ive decided to do , Im gona follow all my slaves back to PF also.

Excuse me dude, but if the mutants changed him, you'd have an essential Super Mutant. One that you could not kill. He was really thinking in your best interest there.

And on a slightly more serious note, I got tired of seeing dad get K.O'd by every dog, mole rat and protectron out there, so I waited until he was in combat and dropped a Tri-Beam Laser Rifle with plenty of ammo for him. It worked.

That SUX. I really hate un-killable characters. I understand the reason behind it, but why not just write-in a new character? For Dad/James that would be extremely difficult, but for everyone else it should be feasible. I haven't got Skyrim, but the mo I read about it the less I like it.

Some characters are essential despite not even being important.
I think there is a woman in Whiterun named Ysolve, and the only thing you can do for her is bring her Sleeping Tree Sap, which is a really really really minor unmarked quest, yet, she cannot be killed.
So there are a crapload of characters with really minor involvement that still cannot be killed for some stupid reason, even after you complete their quests and they are no longer really needed.

Following Dad on his journey has become one of my favorite parts of the game. I always lag way behind him so as to maximize the giggle factor. He rushed a Mutie Overlord with his bare fists while I peeked out from behind a highway divider. Once he stormed a Mutie camp and being a good daughter, I shot one of the Muties who was trying to kill him. Dad looted the minigun and went to spraying bullets but somehow managed to get the backpack of the gun hung up between two pieces of the metal spiky architecture pieces. He was stuck there dangling in the air while the rest of the camp wailed on him.

Gabe- Kinda takes sum o' the fun away eh? It's like I like enslavin foos, but since sum folks are immune I have to look on the internet to see if its even possible. Bumma.

Ghouls- Good story. Dads a crazy-ask foo.

Crazy dad is crazy o.o
But yea I love dad he is freaking awesome
He punched every single enemy to death on the way to Rivet.
