If Mastermold can control Nimrod, that means that there may be other weaknesses that Nimrod has. Just because Venom beat down Super Man in a cross over, does that mean that we shouldn't have threads such as "Super Man vs Juggernaut" since Juggernaut beat Venom?
Such as what I said, Mastermold mass producing 1000s of Sentinels to attack Nimrod.
