This might seem like a condescending question, but I only ask out of genuine curiosity:
What exactly is the purpose of rallying for unlikely characters? Perhaps for mainline Smash games I can understand it a bit more, but for DLC, character numbers are pretty limited. For me, if I want to spend hours of my time rallying for a DLC character, I think to myself "could this character conceivably be within the first ten DLC additions?" Supporting characters like K. Rool, Wolf, Isaac, Inkling, and Dixie make sense in this regard. But how fruitful is a DLC campaign for someone like Travis Touchdown going to be?
Sometimes you have characters that spike way up in popularity suddenly, like Shovel Knight, but those are very rare and incidental (and his popularity has pretty much totally died out by now). If you enjoy discussing the character and speculating about what they would look like in Smash, that's fine, but I couldn't imagine trying to run a thread and Twitter account for these types of characters on a daily basis. It'd be exhausting and mostly unproductive. Most of the time, either the character is popular and/or likely or not; very few are going to be on the fence.
