I always like bringing Arcade Gannon with me as I roamed the wastes.

Good question as there have been many great companions. I'd say Sulik from Fallout 2. He is a very interesting and unique companion seeing as how he keeps one of his grandfather's bones through his nose and regularly converses with spirits. Not to mention he slays with a ripper and .223 pistol.

Fallout has been long overdo for another good tribal companion.

Boone is a close second though. Out of all the NV companions he had the most fleshed out back story and quest. And give him an anti material rifle and say bye bye to those pesky deathclaws. Plus I always love his end slides when you get the best ending for him.

I love having Danse and Dogmeat as companion but right now im getting into playing with cait, she has a very dark past, but taking her to the right path makes her a nice companion to fight with.

Fallout New Vegas: Boone - He is probably the best companion in vanilla Fallout. His story is so saddening when he tells you everything. He is pretty much a must have partner if you're doing a NCR playthrough. I love all of NV's companions, but he is definitely up there. For modded, it would definitely have to be Vincent Vincent. He is such a well written character. I am always excited about what he's about to say when I talk to him. I still haven't heard everything he said, too! That's how in depth of character he is. Just play the mod and you'll see.

Fallout 3: Charon - This guy is so badass, especially if you get the Charon Improved mod.

Fallout 4: Danse - I loved all the companions in Fallout 4, but Danse was my favorite. The big twist in the main quest was what made him one of my favorite characters in Fallout. It was really one of those choices that conflicted with you.

Cass is my favorite or Veronica) (Sorry that I can not take both of them with me)

Boone. He's the most interesting and very useful.

ED-E is also good because he is very useful as well. Enhanced radar, reloading bench, workbench, free daily repairs, and free energy ammo. He is definitely practical.

Mine would have to be Dogmeat, because no matter which dog accompanies you throughout the Fallout series, Dogmeat lives through them. My favorite non-animal companion would probably have to be Nick Valentine, it's like he's ripped straight out of an old Noir detective film and I love it.

Butch, he stabbed a deathclaw to death with his switchblade, he won my heart that day.

It would probably be Dogmeat in FO3. I keep treating Dogmeat as my pet beagle Overly protective and I get really mad fast when the raiders shoot him to near death. It just grinds my gears. Shoot me instead, not my pupperino.

Umm, is every companion in New Vegas allowed as an answer? It's really hard for me to choose between Raul, Cass, Veronica, Arcade, Boone, Dean Domino, Christine, God/Dog and ED-E. They're all just such great and interesting characters for me, brought to life by great voice acting and perfect lines:

"Thumbs down you son of a bitch."

And fully fleshed out backstories that you so rarely get in games (hence why I'm still playing New Vegas six years after its full release).

With the original Fallouts I guess I'll say Dogmeat in Fallout (god bless, you wonderful mutt) and Marcus and Cassidy in Fallout 2.

And for different reasons, I love Myron. Not as a companion, though. I just get a lot of satisfaction from blowing his brains out.

I'd say that E-DE was my right hand man. That little bot never failed me in combat and was always by my side. I like how deep their story was.

Veronica. Interesting faction and backstory. However all companion in NV are great lol!
