One thing caught my eye on that video is the humanoid torso on top reminds me of Adam from the Evangelion anime. According to Wikipedia about the sword Joyeuse "Some legends claim that it was forged to contain the Lance of Longinus within its pommel". In the anime the Lance belonged to Adam and was used by the Eva's to battle the angels. The cool thing is that the Lance of Longinus is also called the Spear of Destiny. I wonder if there's a connection.
