This "Dark Avenger" treatment for 4E may remind you of someone, but I'll let you figure it out on your own. A pretty good treatment of an iconic superhero character for 4E - but I can't figure out how JLA is supposed to stand for Judicial Society of Adventurers...

A 30th-level Batman for D&D 4th edition … it's as simple as that. Quinn Murphy does a good job of modeling Batman using D&D mechanics. I also had fun remembering my AD&D attempts to gather just the right magic items to turn my paladin into Iron Man. The writeup does need a few grammar fixes, and the publisher apparently used a 4e icon font that isn't embedded in the PDF, causing power names to read "m Heroic Fighting," "r Throwing Disc," and so on. It's a lot of fun. I doubt I'll ever actually put the Dark Avenger to use in any D&D campaign, but a dollar is not too much to drop on an entertaining diversion.
