It would be funny how bad Superman would get owned if Flash had such a thing.

seriously it would

batman has the shard of kryptonite

green arrow has a kryptonite arrow

i mean hey flash in a kryptonite costume would just be crazy and funny

i think the main reason is that Kryptonite gives you cancer if you have too much contact with it, why do you think batman keeps his Kryptonite in lead

shit i forgot about that but i thought that was do to over exposure of years with it

another thing i was thinking about just now is hal vs superman in the next fight now the gl ring grants the bearer power right as long as he or she uses there imagination. now couldnt hal simply create a kryptonite bullet or create magic with his ring if his imagination allows him to in order to defeat superman?

i mean afterall hal did kill krona who btw is a guardian

Probably because DC only likes Batman to prepared for savage hero on hero combat.

as far as the voting gos i picked gl over superman since i want to see superman not win lol

also im a huge lantern fan so i had to rock with hal

Yea the cancer thing,,Lex Luthor lost his hand once because he permanently wore the ring.

but flash wouldnt because he would only use the costume 1 time lex always tended to have some form of the shit around him 247 hence why he ended up the way he did
