These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Canon Sue: Deconstructed hilariously in Jaden. Despite his constant cocky bragging about "being the best duelist", "being flawless", and winning nearly every duel (with the entire cast begrudgingly admitting that he has a point), he gets humiliated, beaten-up and nearly killed multiple times an episode by pretty much every character he pisses off (i.e. the entire cast). If there is a dog present, he will be chewed on.
