well, Obviously, no one here acutually knows the facts, so I present them to you uncensored.
1) a light saber is generated by a rare substance, known on the planet earth, as "kryptonite"...but known in other parts iof the universe as "light sabor generating stuff"...(true)
2) Superman IS A JEDI KNIGHT, (true), became so as a birth right, generated by his fathers past...and therefore, the question you are asking, is mute.
3) superman needs the radiation generated by a yellow sun, to be superman in the first place
and finally;
4)I am superman, I am a jedi night, I am dealer, I am a moderator at xper-ience.org...
and most impressive of all,
I am perris
