With all the Star Wars figures I had of course I inserted myself into the Star Wars universe. I was a rebel and often flew the Y-Wing.
I was also a Colonial Warrior flying a Viper when Battlestar Galactica first aired back in the day.
Not sure how many people remember when there was only one monthly X-Men title but that's when I use to hang with the X-Men. I don't recall what my powers were.
