I don't know how everyone else think.. but the min I saw the 2nd episode of Seed Destiny, I realized that Phantom Pain's voice was the same voice has Muu... So only one question.... Is he really Muu? Or is he a clone???

What I think....
His mobile armor.. if u want to call it that... Looked just like the ZERO moblis...
Hair color same....
Has NewType ability...
