This entirely theoretical build is designed to teleport the sun offensively. In theory, it steadily destroys the universe, or instantly destroys the planet. For less violent options, you can merely teleport your enemies into space, onto visible stars or the moon, or to remote mountains.

Requirements:
Cosmic Connection (Cosmic Soul's L30 feature) changes all ranged powers to ranged sight.
Space Vortex (L23 Psion attack) teleports your target to within 5 squares of you. It also incidentally makes a basic attack at +8 to attack and damage. In case the Sun has a pretty good basic attack.

Optional (make everything more awesome):
Mirror Darkly (L6 Warlock) allows you to originate attacks and other effects from it, instead of yourself.
Paladin’s Truth (Paladin feat) allows you to ignore immunities on targets marked by you.
Horns of Balinor (Holy Symbol) makes space vortex mark your target, so that paladin’s truth lets you ignore immunities (in case your DM claims stars are immune to being teleported).

Note that these are all easily combined, via multiclassing, hybriding, or being a tiefling for secrets of belial. For example, be a tiefling psion/paladin.

Process:
1. Pick two stars in the sky that you can see. Create a mirror darkly near one. Use Space Vortex on the other one, teleporting the second star close to the first star. This should steadily destroy the rest of the universe. Supernovas may accelerate the process.
Repeat Step 1 every 5 minutes.
2. Attack the sun overhead and teleport it to within 5 squares of you. Use “Merge with the Cosmos” (L26 Cosmic Soul) to avoid death, achieving immortality now that _everything_ is inside a star.

Special: If anyone attempts to interfere with your plan, teleport them onto the sun (save or die) or, more reliably, somewhere they won’t get a save, like a distant mountain or the moon if it has an atmosphere and isn’t hindering terrain.
