- Bizarro Episode:
- "Monster Drama" is a complete Mind Screw from start to finish, complete with one of the weirdest fight scenes ever. Appropriately, the episode was directed by Akio Jissoji, maverick of the Ultra Series.
- "Ephemeral Dream". Let's see: Mai pilots a giant robot, Captain Munakata and Shinjoh are now pirates (they converted the Artdessei into a pirate ship!), and a completely random scene of Asuka being kicked by a mob of Alien Regulan. Perhaps unsurprisingly, it was All Just a Dream.
- Ear Worm: Whoa, whoa, DYNA
- Ensemble Dark Horse: Often tied with Evil Is Cool:
- Neosaurus, as well as Reicubas, Monsarger, Sildron, and Darambia.
- Imitation Ultraman Dyna/Gregorl-Man, due to the gold and black on the blue details other than his eyebags. 10 points if you include his trademark Ass-Kicking Pose.
- Terranoid. Despite appearing only briefly its debut, the robot's appearance was enough to gain it quite a bit of popularity.
- Harsher in Hindsight: In episode 19, Mai joked that Asuka would never get a girlfriend since he always thinking about monster. With the final episode has Asuka (as Dyna no less) absorbed into a wormhole created from Gransphire's destruction, he won't have a normal life because Asuka is now hundreds of years old (per his actor's words), having travel through various dimensions and fight evil due to his dedication as an Ultraman.
- Hilarious in Hindsight: Aside from Shin Asuka sharing his name to a Mobile Suit pilot, his actor is also a fan of the original Mobile Suit Gundam!
- Tough Act to Follow: Dyna's fall into obscurity seems to be attributable to this, given that as the Lighter and Softer Sequel Series to Ultraman Tiga, one of the best-loved Ultra series, it didn't quite win over fans quite like Tiga did.
YMMV / Ultraman Dyna
