Odin is quite presumptuous, discussing the distribution of the power of the holy halo even before obtaining it. It's a stance of assured victory.
The situation is quite simple.
The Divine Alliance has to divide its powers among various forces, including Zeus's Olympus with its 12 gods, each acting independently, as well as the power of God.
If these forces were united, they would undoubtedly be invincible, but scattered, they are nothing more than a rabble.
Their Ultimate Force Alliance, with most races looking up to Odin as the leader, aims to harness the collective strength of the Alliance.
Could they not secure even a strand of the holy halo's power? If not, the Ultimate Force Alliance might as well disband.
Most importantly, Forseti is a Shapeshifter who receives special attention from William the Obliterator!
