Samurai

Toshiro Eto is a history teacher at a secondary school in Japan by day and the superpowered hero known as Samurai by night.

History
Samurai first appeared when Manhunter went to Japan. The two of them teamed up to fight the assassin Bronze Tiger, who had been hired to kill Manhunter. They were able to prevent Bronze Tiger from completing his mission, but he escaped being captured.

Samurai continued to work with Manhunter in Japan up until they were contacted by the All-Star Squadron and asked to join.

While most of the Justice League was away fighting Superboy-Prime for the second time, Samurai and his fellow All-Star Squadron members helped Aquaman and Supergirl fight the rampaging Tornado Tyrant. Samurai's wind manipulating abilities proved to be helpful in combating Tornado Tyrant; however, his power over the wind was much weaker than the villainous wind elemental's. Tornado Tyrant would ultimately be defeated thanks primarily to the help of the former supervillain El Dorado.
