What are some of the most advanced technologies/resources that batman has made or has access to?
@veshark: I know there's the regular (green), black, red, white, and gold. Red if I recall correctly was green that passed through a crimson cloud and it temporarily took away Kryptonian's abilities. Not sure if I'm remembering that right though.
The coolest weapon Batman ever had (in the comics) was when he created Kryptonite Gauntlets out of Kryptonite Superman gave him. Which he actually used and wrecked Superman with.
Post-Crisis-wise, red kryptonite was an artificial creation by Batman as I recall. Made to overload Kryptonian cells so they absorbed too much sunlight and the target was incapacitated.
I think Batman only had the Kryptonite gauntlets in DK2, in Pre-52 he only had the kryptonite ring.
