Chief (Armored core 5)
"Human beings are just so damn interesting!!!" (My favorite line from the game)
Chief is generally sadistic and rude, constantly acting on his own desires than orders
It is hinted at, but never blatantly stated, that Chief is an AI, completely self-aware.
Sam (Vanquish)
Smoker,gunner,runner. he is so badd ass when the bullets are flying he'll take a smoke break behind some cover. (those who played the game know what im taking about)
