God ULTIMO is awful. Take every manga cliche, put it into one series, and there you go. I personally blame Stan Lee. Comic Books have to be very unoriginal to appeal to the mainstream, but the same mentality does not apply to manga. All shonen manga needs is an unoriginal theme - get strong and beat the bad guys - and you can do whatever the hell you want with the plot (see Yu-Gi-Oh and Bakuman).

I'm going to assume you read book one and quit. In book two, one chapter in, our cute little good guy Ultimo goes bat sh*t insane. By book four, the plot gets very in depth and interesting. It's not a 'get strong and beat the bad guys' manga it's a 'stop the fight from ever happening' manga.
