- Contested Sequel: To Goranger.
- Ensemble Dark Horse: BIIIIGGGG ONEEE!!! Seriously, this is the guy from a cancelled Sentai series, yet he's the closest the series can get for a mascot (Well, his actor being Hiroshi Miyauchi plays a lot of factors for this). And he's not even amongst the initial lineup!
- Oddly enough, while the show was airing, he was actually considered something of a Scrappy, due to the fact that he made the series considerably Lighter and Softer, and because he replaced Commander Kujirai. Some even point to him as a principal cause of JAKQ being the only Super Sentai to be canceled. Of course, the reason why he was introduced in the first place was because kids were avoiding JAKQ because it was getting too much Darker and Edgier for them.
- Guess who represents JAKQ in both Gaoranger's and Gokaiger's anniversary teamup movie? Not bad for a guy who was originally part of an unpopular Retool.
- Harsher in Hindsight: JAKQ is funded by an organization called ISSIS. One less "S" and it becomes REALLY uncomfortable.
- Hilarious in Hindsight: An extra Ranger that's colored white later joins the team as their new leader.
- As noted on the Trivia page, Spade Ace and Dia Jack were originally planned as the Blue and Red Rangers respectively, which would've also resulted in their roles being swapped but had their colors and roles switched in the final product. Take a wild guess what colors the Spade-themed Blade and Diamond-themed Garren from the aforementioned Kamen Rider Blade are.
- Memetic Badass: Big One again.
- Most Wonderful Sound: BIIIIIGGGG ONE!
- Replacement Scrappy: Big One, at first.
- Rescued from the Scrappy Heap: Big One. Notice a trend on this page?
- Retroactive Recognition: Eagle-eyed viewers may be able to spot one Hiroyuki Sanada as Katsuya in episode 9.
- Tough Act to Follow: This series is an attempt to gain the same popularity of its predecesor Himitsu Sentai Goranger, unfortunately, it didn't last long.
- Vindicated by History: ...We're not even going to say who anymore...
- The series itself. Back in the day, it started as too much Darker and Edgier than Goranger for the kiddies, and then when its tone and direction swerved, it lost what those who did enjoy it liked about it, ultimately pleasing no one and having its episode count slashed; its predecessor went 84 episodes while it went 35. Today? Pre-changes, it's the dark sentai that adult fans love, and post-changes, it's the sentai that has you-know-who.
YMMV / J.A.K.Q. Dengekitai
