Here's a favorite from my captioning past. I love using pre-determined transformation universes as a good background for my captions. However, rather than explain the universe within the caption, I write under the assumption that the transformation method is understood and the situation takes front.
So here's the question -- Do you like captions that make use of pre-determined TF universes (Such as Medallion of Zulo or Spells 'R' Us), or would you rather see something more original?
Feel free to discuss the question or the caption!
