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.
Alternative Character Interpretation: Nigel Brightmore is either a Well-Intentioned Extremist who truly believes in Kaijudo traditions, or a Jerk Ass who wants nothing but power and control. Made even more debatable following his Face Heel Turn.
Nigel's views on creatures can either be interpreted as him having a superiority complex or that he is simply mistrustful and resentful of creatures due to having seen the worst from creature kind such as when Toji lost his leg to a creature after attempting to ride it and when Master Tiera was betrayed and killed by her creature partner. In addition the incident with Sasha at the prom seemed to reinforce this as well. He probably has come to expect the worst from creatures. However due to his personality and him usually appearing harsh it may not seem like it that also maybe where his Control Freak tendencies come from. The fact that he joined a man who represents all the worst aspects of humanity that is motivated purely by his own lust for power and ruling two worlds doesn't help. This is something he acknowledges but is desperate enough to do for the sake of not having to completely relinquish his beliefs; it has been a point throughout the show that The Choten's way and Kaijudo aren't all that different simply varying in extremes, he most likely felt that The Choten and his ways were the closest he would now be able to come to Kaijudo. His growing resentment of the kids may also have been the trigger for his action seeing as how they perverted what Kaijudo was.
Arc Fatigue: Over the course of season 2, it's become clearer each episode that Nigel doesn't approve the Choten's methods, and will probably turn against him eventually. Sadly, this doesn't happen until the finale.
I Knew It: Thanks to the early emphasis onRay's missing dad, Saguru's true identity was, if not completely obvious, at least a confident guess for trope-savvy viewers. Luckily, this didn't make The Reveal any less impactful.
Similarly, it became clear quite quickly when Allie's mother came back that she actually was Megaria in disguise, but thanksfully the episode didn't waste time on this by having the characters figure it out quickly and the plot move on.
Lawful Neutral By episode 24, Master Nigel has sided with The Choten. In episode 25, when the other Duel Masters confront Master Nigel about his betrayal, Master Nigel replies that it is the other Duel Masters who broke the rules of Kaijudo. While Master Nigel does not agree with the morals of The Choten, he allies with The Choten to ensure the Kaijudo code and his own personal code are enforced.
Magnificent Bastard: Few tropes could better define The Choten. He is an extremely sick person, but there is no doubt about him being incredibly Bad Ass. As he shows at various points in the series, but especially the first season finale, he knows how to roll with defeat like a real chessmaster too.
Villain Sue: He sadly tends to go more toward this in the second season: so far, absolutely none of the episodes involving him has ended with him really losing, most of them actually concluding in his favor.
Moral Event Horizon: Assuming he didn't cross it before, The Choten would have done it when he wiped out Ken Okamoto's memory and used him to do his job in exchange for giving him his memory back piece by piece, for the sole sake of being sadistic.
Moorna crossed it by the past when she faked accepting Tatsurion as her brother by inviting him to a hunt, only to lead the hunt on his Quillspike family, for the sole sake of hurting him. Even Brutalus, her own betrothed, was shocked and disgusted by this act when he learnt the truth behind it, and Alakshmi turned against her upon hearing this story.
Alakshmi: "I think you have betrayed enough of us in one day!"
What an Idiot: Carny in Caught in the Spotlight. Mere moments after his father advises him not to do anything stupid, he summons his creature in a public venue to show it to his friends, and he starts indiscriminately using its attack to show off. Not only does he almost cause an accident, but a picture of him ends up on the Internet, his father is enraged, and the Choten is after him.
The Woobie: Ray, Gabe, and Allie. Ray because of his Disappeared Dad, his being bullied for his mixed heritage, and his over-all nature lending to him not making many "normal" friends.note He had no problem not going to the school dance, not that he had a date for it anyway. Gabe for being an overweight nerdnote a self-proclaimed nerd at that who has no friends outside of Ray and Allie and for being constantly picked on at school and by his brothers at home. Allie seems okay at first glance, but she actually has some deep-seated mommy abandonment issue.
Iron Woobie: Tatsurion: he was constantly bullied and belittled by the dragon side of his family, with his father never raising a finger and refusing to acknowledge him as his son; the Quillspike side of his family mocked him and gave him a silly nickname, and after he grew up, he ended up a wanted criminal of the whole Fire Civilization, with his dragon sister, Moorna, trying to kill him. Yet don't expect him to even shiver about it.
Carny, of all people, turns out to be one when we find out about his father. Tatsurion was disgusted by how his father treated him.
Roaming Bloodmane when he first appeared. He was trapped on this side of the Veil, thought he was the last of his kind, was ruthless to his human prey, and completely distrustful of the Duel Masters. Yet all he'd ever wanted to do was go home.
