Yay I've argued in more Gundam Vs Evangelion threads than I have toes and fingers
Anyway I don't have much time
Devil Gundam
Practically cannot be defeated by Evas. While AT-Field can protect it from Devil Cells, there's no weapon that an Eva has that can defeat the Devil Gundam since all attacks will instantly regenerate because of Devil Cells. Meanwhile, the Devil Gundam will take over the planet by BECOMING everything on Earth!! If the Eva's are stupid enough to EAT Devil Gundam, then the Devil Cells will be inside them and VOILA! Devil Eva Army
Just keep watching G Gundam if you don't believe that

the devil Gundam is the most powerful Gundam unit in the entire series though the Turn A Gundam would turn it into scrap striaght away if it wanted to....
