Take the dragon balls. Make sure they are the Namekian Dragon balls and you are granted 3 wishes. Use the first wish to become a Jedi. Use the second wish to become a witch/wizard. Use the third wish to become a Green Lantern. With your new-found powers and abilities, you can craft The Ring and create Pokemon.
The green lantern ring is litterally the most overpowered thing out of all of this. So I choose that 1 dragon ball wont do shit other then get you in trouble.
The One Ring will corrupt you like it did to Golem. It gives you invisibility but I mean, did you see the pain it cause Frodo in the movies?
The pokeball wont work because there are no pokemon to catch and you would look like an asshole using it on normal animals and would probably get sued for animal cruelty. Also a single pokeball isn't all that great.
The light saber is a good second choice, but I without the force its not like were going to be jedi's or something.
The wand may be interesting if any of us had any magic potential, but the books say that not everyone has it.
It would still be useless when you can just use the ring to imagine a cage around any wizard you want.
