What's batmans greatest prep feats?

I mean, he is categorized a prep lord in battle forums, but best thing I can think of is those plans he had in tower of bable that apearantly work to beat each JL member alone(weren't excecuted by him though). However, that doesn't put him on the league of people like Reed, Doom, or even Majestic. Also, I read on the top 100 event here once about him beating 4 white maritans or something(can someone provide a scan for that too, pleas?).

Anyway, what is your answer to the question in title.(And no, shooting DS with bullets made out of his weakness amterial doesn't count).

bump?

I personally don't believe he is a prpe lord. He is just really good. He is often mistaken for the best because he has the most talked about prep, also due to him already have done the prep its like he has done a months prep in an hour. He just needs to get the prep he has already done ready.

He beat Amazo.
