Fullmetal Alchemist: Brotherhood - episode 60 - 05 Jun, 2010

Edward and Alphonse battle against Pride, as May tries to take on Father by herself, all while the Ishvalans lay out alkahestry transmutation circles throughout Amestris. In his fight against Wrath, Scar reveals a reconstruction transmutation circle from his brother's research now tattooed on his other arm. Just as Edward's group starts to gain the upper hand, and despite the arrival of Greed, Father grabs the four sacrifices and uses them along with Hohenheim for his transmutation circle, absorbing all the souls in Amestris. This gives Father enough power to open the earth, allowing him to unlock the heaven in the sky and absorb the being within, referred to as the Eye of God. (Source: Wikipedia)
