When your Childhood Friend/benevolent pet gets brainwashed into a menacing beast.
All spoilers will be unmarked. Beware!- 1:
- The Downer Beginning of the entire series starts with the Ultra Flare, which caused a worldwide monster attacks. So how does this happen? When Ultraman X hurls his enemy towards the sun.
- The first monster attack we were treated with is the Molten Iron Monster Demaaga (an original monster), which is said to be an ancient evil. This thing simply made its way to attack the nearby city in sight and would have killed Daichi had not for Ultraman X's appearance.
- Bonus: According to Word of God, Demaaga comes from the hell, making this monster no different to a demon.
- 2: Birdon creating its nest by taking random objects and have several people trapped within it.
- 3:
- The legend of Underground Woman, a "rumored" ghost which was said to lurk within the subways and forces the ground to eat anyone she came across. Considering the last line, this may refer to her summoning Telesdon to gobble her victims.
- The Underground Woman's banshee scream, it is enough to cause disruption in electricity and summons Telesdon from underground. According to Daichi's scanning, her scream indicates sorrow, referring to her dissatisfaction for humanity polluting the night sky with city lights.
- So what was the human disguise of Underground Woman? A long-dead beautician named Ryoko Mabuse. Fridge Horror if one assumed that she may have killed and replace the former.
- 4: Alien Zarab himself. A mad bomber who have destroyed several planets and resort to attack the Earth after that. He summoned a Bemstar to make things worse. Said monster can also be declared as one, having devoured Ultraman X and would have almost digesting him until Xio members freed him.
- 6:
- tE-rU's flashback of Gargorgon's attack on Planet Gold, where he stumbles upon a petrified victim. Said victim was frozen in a state of agony.
- It got worst: Gargorgon had once went down to Earth and petrify an ancient civilization before sinking it. Fridge Horror has it that its the legendary city of Atlantis.
- 7: X sacrifices himself to spare Rudian from being petrified by Gargorgon. Good thing he's brought back later.
- 8: During Zetton's appearance, Ultraman X dons the Zetton Armor in hopes of fighting the monster in equal ground but Dr. Touma, who reveals to be an evil Alien Sran activates the Villain Override function to enslave the Ultraman in against Ultraman Max. Good thing that Daichi managed to expel the malicious programming eventually.
- 10: Although being a breather episode, it just can't escape the trope. Houlinga, a benevolent monster whose in the verge of becoming a mountain as part of its life cycle was mistaken for being ill and nourished with the antidote that forces the widespread of pollen and caused the monster to go on a rampage.
- 11:
- Daichi presses himself so hard that it strains himself into a fatal body fatigue when trying to connect with Cyber Gomora.
- In addition, the original script has it that spoiler:King Joe Custom was captured by Xio members and tried to study its technology, before the robot's own AI hacked the entire base. Good thing that the original plan was scrapped.
- 12: A proper introduction to Dark Thunder Energy, a strange energy source from atop the sky which mutated its targets into rampaging monsters and weaken their Ultraman target. We've seen how it affects Demaaga, as well as X being forcefully separated from Daichi.
- 13 & 14: Mold and Gina Spectre in general. They are the siblings of Juda (who was killed in Ultra Fight Victory). Their plan was to re-awaken all the Spark Dolls in XIO's collection with Dark Thunder Energy to make them into a makeshift army of mindless rampaging beasts to conquer Earth, and that's without mentioning their plan to bring their armies from another dimension into X's world.
- 21: Literally everything about Greeza. It's just so alien and wrong it's like reality can't handle it existing. Its entire existence is otherworldly and unsettling as it appears to phasing in-and-out of reality at random intervals and causes destruction by walking near things without even attacking. It's laugh is probably the worst part, as it is low pitched and echoes all over the place, making Greeza sound like it is everywhere.
- Zaigorg, the Big Bad of the movie. He's a sadistic monster who desires nothing else but to bring about Hell on Earth. Worse yet Word of God, things mentioned In-Universe, and his title Enma Beast (literally Ruler of Hell Beast) implies he's quite literally the Devil himself.
