Really? I swear there was a line in zOMG where X mentioned he built NeXus by embezzlement...lemme see:
Quote:
...solidifying my power base from assets I had hidden while I ran 'his' businesses.
So yeah, he did take some of Johnny's assets
(...erm...) in order to fund NeXus, although one could argue that that technique was only used to build up the company rather than to sustain it.
Which still leaves the question of what it
does other than research the Animated to its own ends.
However, in Manga Zero, it's pretty strongly implied that Edmund's retirement was what allowed Johnny to put the "mad" in "mad science", so to speak. This happened in 1999 (the article is "from" 1/1/00), long before any of us were around to see what G Corp was really meant to do. So that one's easy to explain away: all the awesome world-changing scientific advancements happened when the company was run by someone sane.
