Suggested by Sonic Magnetman is a fairly powerful navi. He never got into the high end level of fighters like Protoman, but he is considerably stronger than Whaleman. Whaleman was taken out in a few seconds by Sharkman and electricity is just a bad match up for him. I expect Whaleman may last a few seconds by running, but Magnetman is also pretty fast with his energy ball technique so Whaleman wouldn’t be able to buy all that much time. Magnetman wins.
