Alternative Versions

Caspian is not like Tyneras; he is not omniversally unique. Since there are an enormous (perhaps infinite) number of alternate versions of many dimensions (including Earth's), there are likewise an enormous (perhaps infinite) number of alternate versions of most important people (if not everyone). These alternate versions may be significantly different (such as “evil” versions of good characters, people being of different races or coming from wildly different backgrounds, and the like), but they’re still recognizable versions of the same person.

There were many others.

Most of these are weaker than the "true" Caspian, a few are even stronger. But none of them have encountered any other versions.

On Earth 3625, Caspian is more self-centered, short-sided and malevolent. His first act was to reduce the world to a barren wasteland where the survivors must live and die at his whim. He travels the world within a massive pyramid on enormous stone rollers, constantly on the move and pursued by throngs of ragged worshipers. The interior of his pyramid has become his sole obsession, and he cares little for the world outside. This Caspian is equal in power to the 'true' Caspian.

On Earth 4567, Caspian's offer to guide the world was accepted, and so no transcenion occurred. This is the world of "Citizen Caspian" storyline. Caspian has taken up residence in the city of Washington DC, specifically the White House. He is still in the process of seizing complete control of his world while terrified populations dread his next terrifying move. This Caspian, being relatively young, is weaker than the main timeline Caspian.

On Earth 8578, a version of Caspian was granted powers far greater than many of his counterparts. His first act was to transform his entire solar system into a immense Dyson sphere, with all attention focused on his throne comprised of every ounce of gold in the solar system. All life within is subject to his merest whim.

On Earth 7181, Caspian with far lesser powers lives a quiet life. He has secured a mansion and grounds for himself, and merely uses his godlike abilities to run his world secretly behind the scenes.

On Earth 467832 the first use of his power killed everything on Earth. Caspian was forced to start again, resurrecting humanity one at a time. This Caspian is more compassionate than any other.
