I'm talking about what happened to Big Boss between Metal Gear 1 & 2. Solidus & Liquid were still alive.
I think it's Big Boss that says it at the end of 4, but body parts of Liquid and Solidus were used to heal him. It explains why Solidus had no legs when you see him (when Eva shows him to you thinking it's Big Boss)

I'm guessing after their second fight they got rid of the robot components then used human parts of his clones. It's just they never mentioned that robot stuff.
