Which Fictional Power Source is the Most Powerful?

Title says it all.

Rate these fictional powers sources in regards to would make each being generally the most amped.

- Your free to just rank the ones you know, or a top 5 and bottom 5 sorta thing.

Round 1: Batman

Round 2: Thanos

- sometimes power source amps would manage to amp a lesser being differently compared to a mighty one in nature.

POWER SOURCES

- Infinity Gauntlet

- White Lantern Ring

- Odin Force

- Phoenix Force

- Anti-Life Equation

- The Power of Cosmic (Marvel)

- Speed Force

- Uni-Power

- The Heart of the Universe

- Omega Effect/Force

- Power of Cyttorak

- Cosmic Cube

- Power of the M'kraan Crystal

- The Omnitrix (Ben 10)

- Toon Force

I welcome anyone to add in any additional sources of power if they want to, if I like the source of power you add I'll add it to here to expand the topic beyond the 15 i started with.

The White Lantern ring should definitely provide the most amp here.

@xearesay: For both combatants?

Any reason . . .

Well, the combined powers of Owen Reese and Beyonder would be the power of a single Cosmic Cube...

Thanks for reading,

The Source >>>>>>> everything else

maybe except the Dunamis Demiurgos
