I personally would like to play as McGyver - Imagine the crafting possibilities.

I'd like to see Rex Power Colt from Blood Dragon as a companion, he has hilarious one-liners, it would never get old hearing those after eliminating a Legion assassin squad.

I would like to see solid snake from metal gear solid 3 as a companion, it would be awesome having him fight by your side. Also if he held a pistol and knife the same as he does in mgs3 that would be cool as well.

This is just because i love "Red Dead Redemption" but Irish would be a hilarious companion. He would be constantly drunk and always be using those witty Irish analogies!

Joel and Ellie from the last of Us would be nice or some ODST Troopers from Halo

I think Chumbucket from Mad Max would be fun to have a little hunchback follow you around

1. Morgan Freeman (why not? lol)
2. Eli (Denzel Washington's character)
3. HUNK (Resident Evil)
4. Ash Williams (The Evil Dead)
5. John Marston (Red Dead Redemption)
6. Pvt. J. Vasquez (Aliens)
7. Adam Jensen (Deus Ex: Human Revolution)
8. Captain Price (Call of duty)
9. Revolver Ocelot. (MGS series)
10. Big Boss. (MGS Series)

Probably been said before, but Max form the new Mad Max game.

Iggy Pop, David Bowie, Charles Bronson, William Shatner, Hugh Hefner, Ripley.

Well, of course, I would go for a Big Boss companion.

Mad Max would be awesome.

I would love to maybe see uhhhhh Hayley Willams just because she's awesome. If not her then Preston Garvey in fallout New Vegas.

Harold from fallout 1,2 and 3

Greta or any of the normal dogs in the Wolfenstein games as either a replacer of Cyber Dogs or a new sort of cyber dog

Captain Martin Walker from Spec Ops The Line I freakin love the game ! And character is Kewl

A SC drone from Iain M Banks "The Culture" series, demilitarized for balance.

Maybe this is dumb, I've ALWAYS wanted to see Bane from The Dark Knight Rises as either a mod, or a companion. He's menacing while being somewhat lore friendly as well. And if his dialog could somehow be extracted through voice clips and used in game I think you'd have the perfect character mod.

The fallout narrator voiced by Ron Perlman.
He could just say "War... War never changes" and shoot people and would still be great.

Aaesith,

Hahaha! Yeeah, I could see that. If they could make it a parody like giving him a robotic Ron Perlman face and a huge weapon and making him say "War never changes" everytime he shot someone..
That would be

Mad Max(Tom Hardy) Companion. I just fell as if he belongs in this universe. So does Eli, and many more people. I'll come back to this thread when I can name my top interests.

Cyrus from Dawn of War II. Invisibility, an evil powerful sniper rifle, advanced C4 charges, land mines, demolition packs, and two scout teammates with bolter and shotgun? Yes please.
I'd also want Tarkus from the same game. Tactical advance to raise ranged damage resistance, break suppression, inspire teammates to do the same, and stay alive until the ability expires. The magical art of grenade fu, throwing three frag grenades with a cooldown between uses. Plus three teammates, with the potential to be Sternguard veterans with plasma guns and relic bolters. Sign me up.
I already play as a pseudo force commander with a super sledge, blood ravens veteran armor, energy shield, and Astartes healing kits.
