What is the card that you get when you fuse the god cards?

Answer 1

Actions that appear in the anime do not necessarily reflect real-world game mechanics. In the anime, Pharaoh Atem fuses all three God Cards to create The Creator God of Light, Horakthy. It was the only Monster Ka that could defeat Zorc Necrophades (also known as Zorc the Dark One). Although this monster appears in the anime, it has never been released as an official card by Konami in either the OCG or the TCG.

Currently, only two of the three God Cards have been released as tournament-legal Effect Monsters (The Winged Dragon of Raand Obelisk the Tormentor). Silfer the Sky Dragon is the only card that has yet to be released. This alone, makes it impossible for The Creator God of Light, Horakthy or any similar card to exist.
