Ryosuke is determined; he will find Bagi, and he will kill her. He has been searching for her for five years, but has known her much longer than that. Ryosuke had been a lonely child, as his parents were away working most of the time. He was given a kitten that he took quickly to, despite the fact that she didn’t look or act quite 'normal'. He named her Bagi, and they lived as best friends… until everyone around started to notice how different she really was and so she was discarded. Now, over a decade later, word has spread that Bagi has been terrorizing villages deep in the South American jungles and leaving many dead. With the help of a young village boy, Ryosuke sets out to stop her, but will he really have the heart to take her life?
Ikurou is a young man with problems: after a terrible car accident, he was captured by a seedy organization and implanted with a parasite known as Baoh -- a creature which bestows superhuman powers on its host, especially when mortally wounded. While being transported by train, he is accidentally set free by Sumire, young a psychic girl, and the two make their escape. With more of his humanity slipping away by the minute, and the organization hot on their tracks, will the two escape with their lives, or simply cause a bloodbath along the way?
Although Bagi is much more emotional and Baoh is rather action-packed, both movies have the same premise: a monster is being chased because he is considered to be a danger to people, but once you get to know them better you see that they might be more human than their hunters.
Both anime are based on characters created by Tezuka. In both anime, scientists interfere with nature in some way whether it is creating an enviroment (in JEL2009), creating mutants (in Bagi), or cloning (in both). Bagi is a bit darker (though JEL2009 has it's share of dark moments too). Still, if you like one then you might like the other.
