Why the hell would the strength be shown before? Envy hasn't fought that much. Only once with Ed, and they wanted to keep him alive. The second time with Greed, and Envy didn't even try to hit Greed. There was no POINT to show it. It was a hidden ability.
And I fail to see how Envy is adrogynous. It didn't even cross my mind that Envy might be (but obviously is not) a girl, the first time I saw him. -.-;;
