Logan

Logan is a Robo-soldier from the 5th Universe. He is the first adversary to be seen against Kino and his friends and continued to be until the second half of the series. However, during the second part of RevEvolution, it is revealed that he is not as "evil" as previously thought. His main motivation is to atone for not being able to protect 'his lady' Phoenix, the wife of Hades, and has had a strong desire to become stronger ever since.
