I was reading an article in USA Today about the top grossing movies of that time. One was Teenage Mutant Ninja Turtles and the other was one of the Batman movies. Inspired, I set out to create my own superhero. I liked the word ‘ninja’ it just sounded very mysterious. He needed a weapon, and a baseball bat came to mind (maybe an influence from the original Walking Tall movie starring Joe Don Baker) and he was a man. So there it is — Ninja Baseball Bat Man!
Now that I had the name, I need to develop his universe. I knew that baseball was the national pastime in Japan and being a baseball fan myself I started to draw the Ninja Baseball Bat Man character in a baseball uniform with his weapon being a baseball bat. After I finished, I needed to think of his enemies, that’s when it really started to roll. Enemy #1 Double Header (a bad guy with two heads), #2 Bat Boy (a Bat wielding two dangerous bats), #3 Spit Ball (a baseball spitting fire), Pinch Hitter, Fowl Ball, Screw Ball, and on and on. So I incorporated Baseball terminology to the characters and the framework for the game was complete. I submitted my character sketch to Irem Japan, and to my surprise they liked it. I was then asked to develop a storyline. I developed a plot in which a criminal breaks into the Baseball Hall of Fame and steals 7 valuable artifacts. The Commissioner of Baseball hires Ninja Baseball Bat Man to get them back. He will do this by completing several levels in the game and after each level return the stolen items.
