I know Batman 1 million is a super smart Batman, with highly, highly advanced technology. His IQ and technology dwarfs original Batman. Ummm... you all know Hal Jordan, he's just a regular GL, NOT Parallax or Spectre, and Supes 1 million is like strong, has some for of 5th dimension imp powers(magic), ummm... you'd need a DC fanboy to tell you more on these characters. Or someone more knowledgeable than me. I'm a marvel fanboy.
Here's a short description of the Keeper:
As many rivers and streams flow from a great body of water, so are the currents of time. Many different channels flowing to an endless sea of destiny. And as a river may change its course turn one way when once it traveled another, so to the path of our heroes life. There is no telling for certain what fate may bring The Silver Surfer. In one of these streams of time the cosmic entity Eon has chosen the Surfer to wear the quantum bands and become the Protector of The Universe! He has volunteered to once again lead the awesome force of nature known as Galactus to his next meal. But this time not as his servant but as his Keeper! Never again will a planet of sentient beings fall before the great hunger of the World Devourer. The Keeper learned to unlocked the power of the quantum bands far beyond Quasar's knowledge of their use. These combined with his innate cosmic power have made him a brought him to a level of power unprecedented for a being born mortal.
My sig is a picture of him. Surfer with the quantum bands.
Here is a descrip of Supes 1M
"The sum of the abilities of the Superman Dynasty as displayed by Superman M* is quite impressive. He is capable to travelling faster than the speed of light (but only under the influence of the Super-Sun), he is also strong enough to punch through the time barrier, leap between planets and invulnerable to practically everything. Along with the traditional Kryptonian senses ten new abilities were added to the Dynasty by the marriage of a Superman to Queen Gzntplzk of the Fifth Dimension. These new abilities include techno-rapport (the ability to control computers), limited control of magnetism, genesis level intellect, super-ESP (a form of super-hypnosis), no longer as susceptible to magic, the ability to think billions of different lines of thought at the same time, etc. However all these abilities are dependent on the covenant with Supermen Prime, they are his gifts to give or revoke at will.
