At the same time that I was witing the Protectors, a friend of mine decided to start writing his own team. he called them the Vindicators, but I presume they went nowhere, as I never got to read a single story he wrote about them. However, because we were doing them at the same time, I decided to have my first "crossover" event in the second chapter. So the Vindicators mentioned there is his team. I just have them join up with the Protectors on a mission.
