You must assemble a 7-person team to combat attacking aliens.

[siahsargus]

Jason Todd (The best Robin, also, sexy.)
The Medic (keep the group alive)
Heavy Weapons Guy (for Tanking)
Master Chief (for luck)
Yahtzee (for snark)
The Flash (INFINITE MASS PUNCH!)
Gordon Freeman (prior experience, good references)

 

[AlexLoxate]

OK, I choose:

Batman,
Commander Shepard,
Ezio Auditore,
Pikachu,
The Mask,
Cole Phelps (so he could go apeshit during the interrogations of captured aliens), and last but not least, Special agent Dale Cooper

 

[X_Kill]

The first bridge crew of the Enterprise. Problem solved. Engage !

 

[Zarthek]

Gordon Freeman - Don't even need to explain this pick.
Barney Calhoun - Tactical leader of the Resistance, experience fighting aliens.
Adrian Sheppard (Half-life: Opposing Force) - About the same, if not more experience than Gordon with aliens.
Dog - Considering the damage he causes in the Half-life games...
Jim Raynor - Loads of experience fighting aliens, and connections to a pretty well organized fighting force doesn't hurt at all either.
The Heavy - Big Russian dude with a minigun.. what else needs to be said?
The Medic - Keeps said Russian dude (And everyone else) alive and can temporarily make him immune to... just about everything.

 

[Corey Longest]

Superman- near indestructible, great leader, prior experience with aliens
Captain America-indestructible shield, expert tactition
Master Chief- prior experience, really lucky
Reed Richards- prior experience, super genius
Batman- prior experience, incites fear
The Doctor- prior experience, and bow ties are cool
Red Hulk- military experience, Omega level strength

7 Space Marines from the Warhammer 40k series. At least 2 of them from the Grey Knights chapter.

 

[GreyKnight3445]

Star Killer (Close quarters combat guy)
Megatron (heavy weapons guy)
Omega Supreme (anti-mothership guy)
Master Chief (ground combat specialist guy)
Shaun from Assassin`s Creed (hacker guy)
Linda from Halo (sniper gal)
Farseer Taldeer (access to Black Library gal)

Best tag team ever.

 

[TheCrapMaster]

Well the easy choice would be to take pre-heresy emperor and 6 primarchs from warhammer 40K universe. But that would be to easy.

But game characters would be.
Commander shepard: For brilliant tactics + he got a nice ship that would come in handy.
Kratos, we want a melee monster to jump in and cause chaos.
Duke nukem, number 1 alien killer.
Master cheif, number 2 alien killer.
Ryu hayabusa, another melee monster but needed for possible required stealth.
Gordon Freeman, the teams scientist who can adapt alien technologi AND handle himself more then enough in a fire fight.
The medic from team fortress 2, my boys aint got time to bleed so he can heal them on the move.

StarFox, Goku, Batman, The Invisible Woman, Commander Shepard, Mace Windu, and last of all! Bruce Lee.

 

[Rack]

Goku
Gohan
Trunks
Superman
Piccolo
Bayonetta

Dull but should be pretty safe, an insanely overpowering level of strength backed up by tactical genius.

Urdnot Wrex.
Spike Spiegel.
Batman.
Jack Churchill. (Real life [http://en.wikipedia.org/wiki/Jack_Churchill] British Soldier who made the only verified kill with a Longbow in WW2)

My Seven
1) Duke Nukem, cause well, this is just wat he does, other then chew bubble gum. And i won't give him bubble gum.
2) Chuck Norris, cause he's CHUCK FUCKING NORRIS
3) Rambo, because apparently he never dies, he just reloads
4) Kratos, because, well, he's the Greek GOD OF FUCKING WAR, if the games are to be believed
5) The White Death, sniper from Finland, just before WWII. Read it and weep---> http://en.wikipedia.org/wiki/Simo_H%C3%A4yh%C3%A4
6) John Marston, because, well, let's face it he's awesome
7) Rob Roy, Navy Seal representative from Deadliest Warrior. That dude was crazy!!!! To see in action, click here---> http://www.youtube.com/watch?v=IPM1TO_al84
