How do you beat serenade in megaman battle network 3

It seems impossible doesn't it? But . . . well, it's just really hard. Or, to be more accurate, it takes a really LONG time, making it nearly impossible to S rank him. What you need to do is basically just wait, and dodge his attacks, until he puts his hand out, a green burst of energy comes out, and your squares get riddled with hits. At that point, hit him with something like 2xhero or Masterstyle (2xhero preferred). Repeat this process, and eventually you'll kill him. More of a stamina battle then anything else.
