The Sadamoto Manga, known only as 'Neon Genesis Evangelion.'
This is the most official Evangelion manga, drawn and written by the character designer of Evangelion. While he cuts down on the number of Angels, Sadamoto digs deeper into the characters than the anime director Anno ever bothered to even try. We learn about Kaji's past and about a hundred other facts about our favorite NERV personnel, and far more depth has been handed out in 11 manga volumes over the past 12 years than those 26 episodes and 2 movies (not counting the new movie quadrilogy coming out, with the first one released...) combined - almost to the point where it gets depressing. After all, this is Anno's creation... yet someone else does vastly better than he ever could.
And while it does deviate from the plot of the anime, it's got Anno's full consent - which works great for Sadamoto.
Like always manga superior...
