Andromeda Key

The Andromeda Key was under the possession of Omega-Xis in the first game. In the games, it looks like a glowing key with a red gem. The anime's depiction of the Andromeda Key is an orb with a claw on it. It is used by the FM to delete a planet (Earth and the AM Planet). It actives the Andromeda.

But even so, it was taken from Omega-Xis helpless and battle weary he could not retreave it. (At the moment).
