Ass Pull: Colonel Shadam being revealed to be a clay doll replica upon his death, despite being responsible for all the Gorma clay dolls (which also qualifies as an Ass Pull on its own, and to a lesser extent, a Shocking Swerve).
Awesome Music: When they pull their roll call, one of the most awesome songs played in Sentai history is played. It really fits the scene.
Harsher in Hindsight: After the suicide of his actor Tatsuya Nomi in May 18 2017, Daigo's status as an Iron Woobie character and being an old man 50 years later has become much sadder in retrospect. note Old Man!Daigo is probably Daigo's around twenties age plus 50 years old. Tatsuya Nomi never reached that age.
Turns out Iron Face Chouryou was in a past team of Dairanger with four other warriors — were they named Ukin, Gakushin, Choukou and Jyokou?Explanation Those are the Japanese names of Wei Kingdom's Five Generals that Zhang Liao (Chouryou) was part of: Yu Jin (Ukin), Yue Jin (Gakushin), Zhang He (Choukou) and Xu Huang (Jyokou)
It turns out that Dairanger preceeded the whole "X years after" trend in Super Sentai that started with Zyuden Sentai Kyoryuger.
The Gorma Emperor mostly appeared to be a fairly harmless Cloud Cuckoolander, until he sees Daijinryu's rampage and makes it clear he doesn't care if the dragon kills all humans on Earth as long as he can rule afterwards.
If Shadam's treatment of Akomaru wasn't enough for this, he definitely crosses with his Evil Plan to become the Gorma Emperor as he doesn't care if his actions bring about Daijinryu's return.
Never Live It Down: Kou stopped fondling Rin's breasts and flipping up her skirt within five episodes of his introduction. But because those five episodes were chock full of instances of him doing it, and because what he did was completely inexcusable, he's become mostly known for this in retrospect.
Surprisingly NOT the monsters, but Ryou's Training from Hell. Imagine you are attached with A LOT of steels that makes your whole body bleed, and you're supposed to go through an extensive training while doing that, and all the while, your body just go through pains and through. Ryou's screams of pain just sounded off... creepy...
Daijinryu's rampages sometimes turn out this way. When he's rampaging across the globe we see an unlucky news caster reporting on it, and when we cut away we hear him screaming implying Daijinryu killed him. Later when he returns he mind controls dozens of people to climb to the tops of buildings. When he looks like he's about to attack them, instead he makes them jump to their deaths.
They Wasted a Perfectly Good Character: Daigo. In the sense that despite being in every episode and having plenty of focus episodes, he remains woefully underdeveloped in the character growth section outside of a romantic subplot. Despite being second-in-command and arguably the best fighter on the team after Ryou, Daigo pretty much wound up as a Satellite Character to Kujaku for all intents and purposes and got little development or characterization beyond being the ranger who loved Kujaku but couldn't be with her.
Vindicated by History: It was, due to a Tough Act to Follow by Jetman (in spite of Zyuranger being chronologically sandwiched between them). This generation seems to be more forgiving, since Kung Fu and Martial Arts are awesome, mix that with Sentai and whoooah.
The Ryuseioh puppet remains one of the most impressive mecha models in Sentai history. There's a reason why it gets shown off so much in the opening credits.
The Dairen-oh outfit also looks very easy to move in. The movements are surprisingly fast, smooth, and impressive.
What An Idiot: Shadam. If you accept the explanation that the return of the Gorma Tribe is a case of "revenge from beyond the grave", where the clay dolls were intended to destroy the Dai tribe. Shadam's golem-clone ends up killing Kaku, the last legitimate claimaint to the Gorma Tribe throne, thus precipitating the extinction of the line. Of course, Shadam might just be hiding.
The Woobie: Love him or hate him, Kou has been through a lot of bad situations whether it be his father Shadam, his twin brother Akomaru, being branded as a kindergartener by his own mother, or that awful prank Rin and Shouji use when we first met him.
