Tetsuwan Birdy
(Birdy the Mighty)
Young Senkawa Tsutomu doesn't know what hit him. After being duped by a shape-shifting alien into becoming a human shield, Tsutomu finds himself killed at the hands of Space Federation office Birdy Altirra Cephon... The problem is, the interstellar police force takes responsibility for their actions, and having innocent bystanders die by their own hands just won't do. But, Tsutomu's own body has been electrified beyond hope...
The end result is that Tsutomu must now share a body with officer Birdy. Unfortunately for Tsutomu, this also means that he isn't always himself (literally) when Birdy is tracking down criminals...
Based on a manga series by Masami Yuuki.
