... You should actually slow down, and listen to the story. That's what the series is mostly about. Heroes and Villains who I think are based off REAL people in REAL events, fighting for dreams and visions they see fit.
He's the only real hero in the MGS series in my view. Solid is simply passive and does what he's told, Liquid is intentionally malignant, Big Boss was simply self-centred, but Solidus cared about his people and wanted to free them, like he said, it wasn't about power. He truly wanted to liberate America. The fact that he is completely ignored in MGS4 is the key reason why I will never buy that game. Solidus was the only one with the vision and guts out of the Snakes.
