YMMV / Ultraman Gaia

  • Bizarro Episode: Episode 29 "Distant City, Uqbar" is one serious Mind Screw.
  • Crowning Moment of Awesome:
    • Gamu schooling the Ace Pilots in how to properly operate their fighters, something they weren't very competent at prior, due to the simple fact he invented the tech they use.
    • Gamu figuring out a way to counter Mezard on their way back to base and having a fully fleshed out plan and method to force it into the physical plan where it can be attacked.
    • The Earth monsters teaming up with humanity and the Ultramen in the Grand Finale could certainly count.
  • Crowning Moment of Funny: The entirety of episode 35 "Ransom for a Monster". A group of Dumb Crooks find the Monster of the Week's egg and decide to hold it for ransom, pretending to be aliens. They accomplish this by barely changing the name of the iron working company they work for. The funniest part is GUARD plays the entire situation completely straight, unaware it's a scam.
  • Ensemble Darkhorse:
    • Ultraman Agul and by extension, Fujimiya. In fact, the two were supposed to be retired when Gaia obtains Agul's power but the sheer amount of Popularity Power allows them to return.
    • Gan Q for the series' monsters. He ranks up with the likes of Gomora, Baltan, Pigmon, and Dada in sheer recognizability amongst Ultra monsters.
    • The series has more recurring non-Japanese characters than any other Japan-produced Ultra Series, so not surprisingly, they've nabbed quite a bit of attention amongst western fans.
  • Fan-Preferred Couple: Gamu and Atsuko. The fact that their relationship never resolves by the end is a major disappointment amongst fans.
  • Hilarious in Hindsight: Chiaki Konaka goes into Kaiju-writing business again three years later.
  • Tear Jerker: Tsuchikera's episode "The Lake of Sadness" is one of the biggest in the Ultra series.
    Kondo: Thank, you, Hirano. Because you were there for me, I managed not to lose my heart. Now I'm ready to go to where Chei is. Thank you, Hirano.
  • They Wasted a Perfectly Good Plot: The relationship between Gamu and Atsuko is this towards most fans, since they never had a resolution in the end despite a lot of plot buildup in-between them. Such examples can be shown on their similarly Friendless Background, Atsuko growing from a Tsundere towards a more warming personality to Gamu and a minor Clingy Jealous Girl moment in episode 42. The OV (taking place sometime after final) has Gamu resuming his life as a university student and Atsuko returns to her Tsundere mode again.
