I'd definitely say more fans, as a whole, know who he is. Casual players are NOT fans. They are people who casually pick up the sticks and play with their buddies every now and then. Fans are people who know the lore and can tell you more characters than "the guy who does freeze balls" or "that one guy that says GET OVER HERE!" I think you have the two confused. If you're a fan of Mortal Kombat, you know the games and most likely look stuff up on YouTube. Chances are, you've probably run across a mugen video that had Tremor in it since a lot of versions do feature him. Also, if you're looking up Mortal Kombat games, you'll run across the ones that weren't featured in the main storyline arc, including Shaolin Monks, Mythologies, and Special Forces. Just because you dislike a character, that does not mean he is not well known. Again, the guy was in the Vita version of the last game...be serious.
