With Burai being a threat to the Zyurangers, even teaming up with the Bandora gang for a time, it makes sense that he's called the Dragon Ranger, since when you break down the word Dragon to its base katakana, you see that he fits the Theme Naming of the Dora Monsters: Doragon.
The two times where Daizyujin was ordering Geki to kill Burai seem to make him a straight up Jerkass God, but later episodes revealing he had Clotho temporary restore Burai to life hint that he was trying to teach Geki a lesson that there are some people can't be redeemed. The fact that Burai was a revenge-driven villain at the time, Daizyujin made a calculated risk that Geki would obtain Zyusouken after giving Burai a mercy kill. But Geki refused to do it and offered his life to Burai instead, causing his older's brother Heel–Face Turn while prolonging his impending death. But Burai ends up finishing what Daizyujin started during the Zyurangers' battle with Goda, who sold her soul to Bandora for revenge, by telling him that Goda is too far gone to be reasoned with.
This also plays in Daizyujin being a guardian of natural order, he tried to stall Burai's death once to arrange the conditions that would allow the Zyurangers to summon Dragon Ceasar. But refuses to interfere further in prolonging Burai's life due to the consequences in the grand scheme of life and death. Burai reaches the similar conclusion and help Geki understand what the deity was trying to teach him.
Why do Mechanical Lifeforms that are literally gods need cockpits and pilots? Considering that the few times Daizyujin operates on his own sees him going into Jerkass Gods-territory, it's obvious that he needs to kept on a tight leash (may overlap with Fridge Horror).
Mei tends to be targeted more by Bandora than the other Zyurangers, especially when she could target Goushi, Dan, and Boy since their Shugozyu are essential in forming Daizyujin and Gouryujin. The reason is due to the Lithia Tribe possessing traits that proved disastrous for Bandora. Like Mei's ancestor Lithiantheus defeated a Ladon with his archery skills or Princess Yui luring a Guzzler terrorizing their kingdom into a death trap. So the times Bandora made attempts on Mei's life was because to cover for the Weaksauce Weakness of Dora Ladon and Dora Guzzle, monsters modeled after the defeated creatures.
There is a logic gap in regards to Daizyujin and Burai.
Since Daizyujin needs Burai so badly (at least until his ability to combine with Dragon Caesar and King Brachion is restored), it makes no sense at all that initially he is adamant that Geki kill Burai. Especially since "Burai Dies" establishes that Burai can't be revived again. There are also some plotholes regarding some of the episodes after Burai joins the team. Mei is targeted for incapacitation by Bandora on a number of occasions, to prevent her from calling Pteranodon to form Daizyujin. This was done to shill Gouryuujin (who doesn't require Pteranodon).
Geki could take Burai's dragon medal, and his powers. While Burai gives them up voluntarily its hinted he could also take them by force if he killed him. In that case Geki would get Dragon Caesar from the start. But since Burai stole the Dragon powers in the past, if he'd died in that cave, they'd be lost with him.
However, Fridge Logic hits when you consider a few things.
The Guardian Beasts, and occasionally Daizyujin as a combined whole, have demonstrated the ability to appear without being called. In Episode 27, Pteranodon even appeared on its own to bail out an unmorphed Mei.
Why doesn't Bandora try targeting Dan, Goushi, or Boi? Their guardian beasts are necessary for both formations. Also, the 5 main Guardian beasts have demonstrated the ability to not only appear on their own but fight autonomously, making one wonder why they need the Rangers to pilot them.
In the final episode, how did Kai survive the Dora Talos exploding long enough to make it back to Bandora Tower?
Wait, in the final episode why did the Zyurangers entrust the baby dinosaurs to children?! Yep, no possible way that can go wrong. To be fair, the baby dinosaurs are the last pair of dinosaurs on Earth, and should the eggs they were hatched from be destroyed, then the dinosaurs would be forever extinct from the world.
To be both smart AND fair, the baby dinosaurs should've been given to scientists or the authorities.
Obviously they knew that this factoid would be completely forgotten about in future seasons, without any need to retcon this as an alternate timeline a la Power Rangers Dino Charge. In-universe, the most logical explanation would be the season's running theme of Children Are Innocent.
Why do the Zyurangers regularly try to take on Dora Monsters before transforming? You'd think after their first few attempts at this resulted in them being knocked aside, they'd stop wasting time and immediately transform.
On several occasions, Grifforzer and Lamie (either together or seperately) have been shown to be more than capable of easily overpowering the five main Zyurangers (in fact, they've never actually lost in an even fight). So why does Bandora even bother with sending Dora Monsters after the heroes, when these two have a much higher success rate?
Griffozer and Lami may be able to overpower the Zyurangers, but they are no match against Daizyuzin. The only time they overpowered it was when a solar eclipse was weakening it and they were also fighting alongside a giant Dragon Ranger.
