- Cute Machines: They're essentially chibi versions of Garagon that sing and dance in an adorable voice.

- Applied Phlebotinum: Garagon is actually a giant brain for the Gara Q. When all the toys are gathered together, they gain a malevolent sentience under the command of Garagon.
- Continuity Nod: Professor Watarai explains that Garagon is essentially an "evolved" version of Garamon — a bigger, better, and stronger Garamon.
- EMP: Produces this from its body in the form of an aurora that causes computers to stop working. It's actually how Garagon controls the Gara Q.
- Hoist by His Own Petard: The second Garagon is destroyed when Ryo's Gara Q manages to reflect the giant's forehead bolt back at it.

- Spiritual Successor: of Garamon, being essentially a rotund version of the classic Ultra Q kaiju.
- First Appearance: Graffiti
- Crop Circles: Goichi hears a story of one in the shape of the aliens' mysterious graffiti symbol, suggesting the aliens do this as well.

- You Know Too Much: Implied to be their reason for targeting Kayoko.
- First Appearance: Who Are You?
- All Just a Dream: Turns out Yamazaki really isn't a brain in a jar...

- Brain in a Jar: Yamazaki actually died when he was just a child. His brain was then kept alive in a lab for decades.
- Dead All Along: He's actually been dead for twenty-five years. His friends and wife are actually the scientists who monitor his brain's status.

- Ambiguously Evil: As a whole.
- The Deliverer helped Goichi escape when the Rat Catchers came after him, but she otherwise leaves hints for him to never return or else. And the Rat Catchers showed no qualms about attacking camp refugees waiting to go to Paradise as they try to capture Goichi.
- Additionally, the true identity of Paradise is never revealed as the refuge camp is destroyed and all its denizens are killed by the Rat Catchers, while Tatsumi mentions that those who are brought to Paradise never return. It's implied something far more nefarious may have been going on.
- Ambiguously Human: The Rat Catchers. Their bodies are fully covered by their white hazmat suits and gas masks, and while they do speak Japanese, they show no other evidence suggesting a human underneath the suits.
- The Dog Was the Mastermind: Goichi recognizes the Deliverer as an incidental office lady he noticed being shouted at by her boss when he was visiting Tatsumi's old workplace to ask around.

- First Appearance: KiaraPlayed by: Arisa Nakamura
- Ambiguously Evil: She may have appeared to help Sakaguchi pursue his dreams of becoming a Jazz star, but there are hints that she may not really be benevolent. She's followed by five ghastly specters that attack people when she wills it and her manipulations of Sakaguchi ends with him dead when she leads him away; not to mention Karkland is shown to have gone insane after meeting her (and one of her ghost servants looks suspiciously like him).
- Our Angels Are Different: Her true identity is an angel who helps Jazz musicians reach their potential. She had previously appeared to Buster Karkland and now appears to Sakaguchi to help him get his career off the ground.

- Amusing Alien: At times.
- Heroic Sacrifice: He plans to use his rebuilt spaceship to do one in order to destroy Sabikong. He survives instead.
- Innocent Aliens: Unitoroda came to Earth to fight of the Sabikong menace, and when he is brought in to be cared for the Tokusuke and his family, his gratefulness cannot be understated (and that is taken Up to Eleven by Tokusuke and his factory workers fixing up his spaceship!).
- Meaningful Name: His name is a combination of the Japanese words for "tuna" and "sea urchin", which also happen to be his favorite types of sushi.

- First Appearance: Temptation at 2 AMPlayed by: Yamaguchi Edo

- Honest John's Dealership: He's basically an extraterrestrial version of your classic fast-talking TV salesman, and although his products actually work, his customers usually wind up demanding the antidote. And it turns out he isn't the only one of his kind stationed above Earth...
- Human Aliens: Really the only indications he's an alien is that he does his work on a space station for a TV channel called Cosmo Shopping and refers to his human customers as Earthlings.

- Psychopomp: He's an ordinary human gifted with supernatural powers in order to help the dying transition to the "the Mother Land" (an individual's happiest memories). However, this gift comes at the cost of his childhood memories.
- Touch of Death: Is able to perform this to help the dying pass away peacefully.
Three-Eyed Totem Pole
- First Appearance: The Eyes of the Totem
- Jackass Genie: It grants wishes alright, but it will take away something you deeply cherish in exchange for each wish granted. The bigger the wish, the more precious the loss.
- Sealed Evil in a Can: The totem pole was created to imprison a demon that feeds on desire. Its twisted wishing-granting power comes from the trapped fiend.
- Shout-Out: Inspired by The Monkey's Paw. Mai's last two wishes are almost the exact same as those made in the story as well.
- Your Soul Is Mine: The final wish takes away the wisher's soul to be devoured by the demon inside totem. The totem then vanishes and reappears elsewhere to await the next victim.
- First Appearance: The Dream Stone
- Jackass Genie: His meteorite perverts wishes as his way of punishing the selfishness of the wishers. The adults of Tsukizuki all wished to become children again — he makes them mindless zombie-like children.
- Human Aliens: He seems to be such, with only his tongues giving away his true identity. However, his upon death, a tentacled creature can be seen trying to escape his mouth, suggesting this was just a disguise.
- Overly Long Tongue: Has several lengthy tentacle-like tongues. They're actually the tentacles of the real Alien Utsugi that lives inside his body.
- Solid Gold Poop: His tongues allow him to vomit out a small green stone that puts one to sleep when consumed. He uses this to ensure the children of Tsukizuki don't see the adults-turned-children frolicking at night.
- Soul Jar: He dies when his meteorite is destroyed, suggesting this to be the case.
- First Appearance: Invader from the Shadows
- Evil Twin: Varno creates these using the Mirror of Darkness. However, they're less evil more unable to tell apart right from wrong, so Goichi was able to teach one about compassion and give her an understanding of morality.
- Hoist by His Own Petard: He and the Mirror of Darkness are destroyed offscreen by Anoru, one of their very own creations.
- Mirror Monster: Exists in the mirror realm and controls a giant reflective crystal that replaces people with mirrored versions of themselves.
- Vader Breath: Makes these as he steps forward from the Mirror of Darkness in search of Anoru and Goichi. His armour and sword add to the effect.

For the original Lilly, see the Ultra Q character page
- Astral Projection: Like the original, Lilly has this power. A phantom duplicate of her manifests whenever she goes to sleep, causing her to enter into a trance.
- Creepy Child: Her evil twin starts of as merely mischievous and a bit of a kleptomaniac, but like in the original Ultra Q story, she's leading her good twin to be hit by a train in the end.
- Evil Twin: It's the result of Lilly's abusive father using her to perfect the separation of body and mind with sensory deprivation tanks. He had tried it on himself earlier and it ended with him being led off a rooftop to his death.
