Tear Jerker / Ultraman Tiga

• "The Man Who Came Down to Earth": Rena's strained relationship with her father, Omi. The former promised to her father a lipstick as a gift to her 9th birthday, but duty calls on that day where he rescued survivors from his ship 13 years ago and fired the Valkyrie Cannon to neutralize the ship trying to collide on his space station. When Rena gets kidnapped by Alien Reguran, Omi finally realizes how he has been missing in her daughter's life and willingly takes the risk of rescuing her with help from GUTS. Eventually, both father and daughter reconcile at the end of the episode.
  • On that same episode, we find out Reguran's family board were inside of the ship destroyed by the TPC's defense cannon. The fact Omi gave the call to open fire, and Reguran in response, kidnapping Rena as revenge and was about to make him pay with his daughter's life doesn't help matters either.
• "The Phantom Dash": Mayumi's boyfriend Takuma Aoki (played by the actual namesake motorcyclist himself) among those who died when his plane attacked and destroyed by Gazort. However, before his death, he still holds his necklace with Mayumi's picture, which made his soul come to help Daigo and Shinjoh distract Gazort II timely, which give Shinjoh enough time to get his younger sister away from the monster. Poor Mayumi didn't take his death too well towards the end of the episode. It still haunts her in the sequel.
• "The Devil's Judgement": Captain Iruma is revealed to be a widow, and not only she is busy as captain of GUTS, but she could also barely keep in touch with her son Tomoki, who lives with his paternal grandmother. Then again, being an Iruma-centered episode (the other being "The Devil's Prophecy"), her mother-in-law falling prey to Kyrieloid's manipulations does not help matters either.
• "I Saw Obiko!": The titular Monster of the Week, Obiko while harmless, yet but a Cloudcuckoolander of a trickster disguised as a noodle vendor who spends the entire episode giving GUTS a wild-goose chase in broad daylight, Mood Whiplash finally sets in midway when Daigo figured out why he enjoys playing around the darkness and scaring a number of people is because that he [Obiko] did not want to be forgotten, and the poor guy decided to go Suicide by Cop by letting Tiga's Hand Slash destroy him and dying on the Ultra's arms made the ending to the episode all the more, if not entirely bittersweet.
• "The One Who Inherits the Shadows": Guardi's death at the hands of his former master Evil Tiga may be an emotional blow for dog lovers.
• "Let's go to Kamakura!": Where to begin? The episode begins with a cameraman taking pictures nearby the Enoden while searching for this episode's Monster of the Week hiding around the railroad. However, nobody believed in him, even GUTS (except for Daigo and Rena) dismissed his sixth sense as merely crying wolf or he's simply lost his mind, so much so that his relationship with his son is further strained. What's worse, the said cameraman started turning to the bottle after his wife passed away, leaving the poor guy to work for his son's needs. Hell, even the kid is bullied by his own friends as if they believed his father is becoming insane over his obsession.
  • On that same episode, it turned out that the MOTW ended up stranded on Earth as the alarm made by the Enoden sounded similar to the Taraban's cries. As Horii discovered that there's also another Taraban prowling around in space, which happens to be the mother, coming into conclusion that the Taraban on Earth is actually a child separated from its mother. Luckily, Tiga managed to bring the child back to its mother.
• The Final Episode: "To The Shining Ones". ALL OF IT. Gathanozoa has put Tiga under the ropes on the wrong end of a Curb-Stomp Battle, and one he lands that final blow, Rena calls Daigo out of worry and fear that he will never come back. Not once, but twice as Tiga once again becomes petrified and he sinks to the bottom of the ocean, trapping Daigo in the statue. Many tears were shed for the fallen hero, and for some time it almost seemed that Tiga was going to have a Downer Ending and that GUTS' efforts were All for Nothing.
  • Just... Rena's face and voice which convey her anguish while she screams Daigo's name. Ouch.
  • Even if Tiga won against The Prince of Darkness, there's still the fact that Tiga has to go back to rest forever as the petrified Spark Lens fades away, but there's a silver lining that Daigo reassures Rena that he will come back if the need arises once more.
  Daigo: Any human... has the power to become a being of light.
