Death Battle - Casshern vs 8-Man

In recent years I took interest in this internet show called "Death Battle", which crosses characters from many different franchises, and puts them in one on one battles. I have seen matches like He-Man vs. Lion-O, Fox McCloud vs. Bucky O'Hare, Ryu Hayabusa vs. Strider Hiryu, etc. And so I decided to make my own idea for a death battle. And I chose these guys; Casshern, and 8-Man. I think this would be an epic battle because 8-Man and Casshern share a lot in common; they're both cyborg superheroes who use their powers to fight evil, they both struggle with their emotions on whether or not they're man or machine, and they even share some of the same abilities. But while 8-Man is super strong, super fast, and super agile, Casshern has a few accessories and abilities that he could use to his advantage. 8-Man first debuted in 1963 with his own self-titled manga and TV series. And many years later, he got his own live action film in 1992 called "8-Man: For All Lonely Nights", and a 1993 OVA series titled "8-Man After", both of which I reviewed earlier. In most versions of the story, 8-Man's real name is Hachiro Azuma. While in "8-Man After", he was succeeded by Hazama Itsuru as the cybernetic superhero. Casshern was created by Tatsunoko Productions, and debuted in 1973 with his own TV series. Like 8-Man before him, he was once human who had his essence transferred from his human body into a robotic body, therefore making him a cyborg similar to 8-Man. And also like 8-Man, Casshern got his own OVA in 1993, and a live action movie that was released in 2004. It's come to my complete shock however, that 8-Man and Casshern both share the same surname. Casshern's real name is Tetsuya Azuma. And mind you, 8-Man came a full decade before Casshern. Not that I have anything against Casshern. In fact, I think Casshern is awesome. But since he and 8-Man seem so similar, I figured it'd be awesome to see which of these two cybernetic superheroes would come out on top if they ever crossed paths. Though, to be honest with you, I don't know who to route for. This fight could go either way.

8-Man belongs to Kazumasa Hirai and Jiro Kuwata.
Casshern belongs to Tatsunoko Productions.
