Trivia

 * It is the only spin-off manga in the  Silver Side Story  series that takes place before  Silver.
 * The Tournament of Silver's Past  was originally going to be part of  Silver, being before the Beast Saga and it would've set up more background information about Silver. However it was scrapped and instead reworked into a spin-off manga.
 * Since the story takes place before  Silver, Colonel Red is the first villain faced by Silver, chronologically predating the Beast.
 * The Evolutionary is mentioned in the story, as Colonel Red explains that he is working for the group and is a high-ranking member. This explains why in  Silver NX, when the Evolutionary's name is said out loud, Silver becomes shocked, stating that the name sounds very familiar.
