Ryusoulger's combination of a brand-new production staff, particularly a new writer known for J-dramasnote the act of bringing in new head writers from outside tokusatsu rather than continuing to reuse the same group of in-house writers is often credited as a factor in Kamen Rider's growth in strength as a brand in the 2010s and a rising star director, with a time-tested theme being reused after an unusually short amount of time, is generally taken as a sign that it's supposed to be this for Super Sentai as a brand after many years of financial underperformance and its predecessor in particular being an unmitigated disaster.
Ryusoulger has also made numerous moves to avoid the pitfalls of its popular but flawed older brother series Zyuden Sentai Kyoryuger. Two of these are an emphasis on the Ryusoulgers actually working together instead of having the Red say they're working together while doing everything himself, KishiRyuOh being modular enough to have a proper full team combination mecha instead of being stuck with only three at any given time by design like the majority of the Zyuden Giants and the Ryusoulgers who aren't in the mecha are still able to contribute in the battle through advice or help from outside through their usage of Souls.
Gaisoulg is an intimidating, mysterious Black Knight (well, purple knight) and it's hard not to be engaged in the scenes where he shows up.
Wizeru can be rather silly, but his flamboyance, massive ego and surprisingly ruthless deviousness make him very entertaining whenever he appears.
Genius Bonus: Towa gets bitten by a dog-like Minusaur and is taken ill with a high fever, which actually mimics the effects of rabies (which thanks to widespread vaccinations are all but forgotten by now).
In 2018, the mobile role-playing game Brave Frontier 2 had a collaboration event with Zyuden Sentai Kyoryuger, with a promotional parody commercial released featuring the main cast of Kyoryuger as knight-like members of a fictitious Sentai based on the RPG, Yuukan Sentai Brave Frontier. Come 2019, and we now have a Sentai series that combines both dinosaurs and fantasy RPG/knight elements into one.
Fans had gripes over the DX Ranger Key toys from Kaizoku Sentai Gokaiger being unable to one-flick change into key mode as it does in the show, which led to the release of a limited-edition "One-Click Ranger Key Set" that introduced a side button that triggers the flick into key mode with a push. The said "one-click change" gimmick was eventually reused for the similarly-shaped DX Ryusoul toyline, and it has now become one of their key selling points.
The Ganglers have the same motif and the same powers like the Ryusoulgers.
Before the reveal, Ryusoulger was thought to be a dragon-based team. Come first episode, and the very first Monster of the Week they have to fight is a dragon.
The Deluxe Megazord released for Power Rangers (2017) was heavily criticized for being basically a "partsformer", with its transformation limited entirely to detaching and reattaching all its parts a different way. The DX Kishiryu take it Up to Eleven with a modular system that's been compared by many to Lego.
The concept of mythological creatures born from/having powers based on a human's psyche was a long running theme in the Persona series of video games. This series takes it particularly akin to Persona 5, where most of said mythological creatures represent the evil side of one's psyche and are the enemy monsters to defeat. Not helping it is that TV Asahi's character pages for the Minusaurs gave them an "experience points" stat, which adds to the overall videogame theme. In that sense, one could say that the Ryusoulgers are fighting against Shadows.
The title of episode of Ryusoulger is "Hell's Watchdog". Guess which voice actor appeared in three episodes as the third Druidon general?
The title was already known due to trademark filings, and its use of "ryu" (dragon) suggested that the season was to be Dragon Knight-themed, which many fans are excited about, since this would be the first time there's a fully dragon-themed team. The revelation that it was actually short for "kyoryu" (dinosaur) was an unwelcome surprise.
The team setup was uncomfortably reminiscent of the most recent previous dinosaur series Zyuden Sentai Kyoryuger: the team colors were the same (Red, Blue, Pink, Black, Green, and Gold; with Pink as the only girl and Green being the youngest), the mecha had the same construction (Red makes the main body, Blue and Pink make the arms), and the Ryusouls act just like the Zyudenchi (not only in providing random extra powers, including a few that were seen in Kyoryuger, but being stored in the belt buckle, in summoning weapons that cover the Rangers' right arms in armor, and in being activated by having the 'mouth' of the weapon all the Rangers share bite down on it). Even those who preferred Ryusoulger's execution of these elements didn't really like that a recent previous season was being rehashed to such a degree.
It continues with the Gold Ranger's introduction. Guess what power his go-to Ryusoul grants?
Gaisorg's reveal also made some fans comparing his armor with Goblin Slayer's.
Bamba murder Explanation A few streams for Ryusoulger show a few comments about how Bamba has been known to kill Minusaur victims as his solution to killing the Minusaur itself, even if the victim was just a box or a rock.
Visual Effects of Awesome: The suit of KishiRyuuOh lacks the blocklike and bulky look its many predecessors have, but in exchange for that the suit is a lot more streamlined which gives its suit actor more freedom to move in and allow more amazing stunts. For example:
While it's just part of the promo. It's amazing to see KishiRyuuOh Three Knights running at full speed against the enemy, but what makes this so amazing is the fact the shot is not made of CGI, instead it's the suit actor running with full force while wearing the heavy costume, something rarely seen in previous Super Sentai. Then there is the full fight, which is almost all practical effects and it's a glorious sight after years of mostly CGI.
KishiRyuOh Five Knights is even more impressive, adding parts of Mirneedle and Tigerlance to the mix in a way that doesn't make the suit feel cluttered and still allows for an impressive amount of movement.
Win Back the Crowd: For Sentai as a brand and as a franchise, since Toei decided to recruit big names outside of Tokusatsu and newcomers like Junpei Yamaoka (the man who wrote Majisuka Gakuen) and Kazuya Kamihoriuchi (the man behind the success of Ex-Aid and Build) in an attempt to bring Sentai back to its former glory after nine consecutive years of TV ratings decline. This also extends to the franchise's toy sales too due to Lupinranger vs. Patranger doing horrible in toy sales and its earnings are just as bad as (or even worse than) the likes of Fiveman and Timeranger.
Also, bringing back the dino theme is an attempt at this. Dinosaurs are always a big seller, and as mentioned before, recent series, even the ones the internet likes, aren't sending toys flying off the shelves back home.
Woolseyism: A lot of Ryusoulger's naming conventions and puns don't translate well into English, so Over-Time's subs substitute those names for these. Expect to see both versions used by editors.
In episode 13, the Ryusoulgers misinterpret the Minusaur's Catchphrase "Wannada" as "It's a trap" (wana da in Japanese), with Asuna remarking that announcing it beforehand defeats the purpose of setting a trap. As the pun would not have worked in English, Over-Time changed it to "Won a ton", with Asuna replying that the Minusaur has to beat them first before saying it.
Mosa Blade insertion announcement = Mosa Graciasnote The phrase in Japanese is "itadaki mosa", which is a play on itadakimasu (loosely, "Thank you [for the food]"). Over-time's translation is also an additional play on the Spanish muchas gracias ("Thank you very much").
