Dark Layton, Dark Phoenix Wright, and Level-5-style Dark Phoenix Wright, scrapped designs from the Professor Layton vs. Ace Attorney artbook. These images were posted by @RyougaSaotome and are awesome.
I want to live in the alternate universe where this is the game. I can kind of visit that universe by searching Tumblr, where Dark Layton fanart is starting to show up in surprising amounts. Warning,
sometimes almost always, searching Tumblr for fanart results in hella NSFW stuff.
