The Mass Production Evas were used for "evil" intentions. The Mass Production Models all had wings to of course, fly with. Their grin and their spears give them an ominous appearance.

The Mass Production Models were incredibly strong. But not strong enough that Asuka couldn't handle them! However, when she "destroyed" all the Mass Production Models, they all regenerated and one punctured Eva-02 through the head with the Lance of Longinus and the rest ate Eva-02 alive. They are also the main cause of the Third Impact!
