Uniformly depicted as a horrible, lecherous doctor, Dr. Iwata owes his prominence in the medical profession mostly to family influence. His most distinct physical feature is the X-shaped scar across his entire face, which was given to him by a four-year old Norikuni Iwata, his cousin, whom he has come to hate since then. His likeness and character are parodies of Osamu Tezuka&#039;s Black Jack. Although several chapters of the manga revolve around him or his hospital, he only has cameo appearances in the anime.

Excel Saga is a one-of-a kind work of art that can only be described as the ultimate parody of anime. From the opening credits - a rather odd spoof of Japanese pop videos - to the ending song featuring Menchi the dog singing/barking a plaintive ballad while a human interpreter translates for viewers, nothing is sacred in the world of Excel Saga.

Earnest young girls Excel and Hyatt (both codenames) hold down minimum-wage jobs to support their true avocation: trying to conquer the city of Fukuoka for the secret organization ACROSS and its dreamy dictator, Il Palazzo--a man whose dignity is such that he could never acknowledge that ACROSS consists of himself, a leaky basement, two unpaid teenage interns, and a stray dog. But society is all to blame, as creator Rikdo Koshi takes aim at everything from organized religion to public television, in a manga that makes reindeer spit blood and puts puppies on the dinner menu.
