So you could think: I should take Kratos, or Duke or any character that simply doesnt care about me and problably will murder me...
If i bring someone it will be either: Megaman, Link, Lara Croft or Alyx...
Megaman is a super friendly robot, very protective and powerfull... Link is a corageous hero, that saved the world countless times, Lara Croft is a super smart and friendly person... good wingmen... or wing-girl... and alyx is smart, a good fighter, awesome personnality, and i can definitly count on her has my backup...
