Beauty Mark: A quite noticeable one under his right eye.
Boring Invincible Hero: Averted in GP 8 as an Aesop. While helping Speedor recover from a bad rust, Sosuke kept believing that a miracle will happen, since they're the heroes; nothing happened. In the end, he decided to make miracles happen, rather than waiting for them.
Mr. Fanservice: Oddly enough. Throughout the season he appears in various states of undress, most of them Played for Laughs given the nature of the show.
Serious Business: Though not to the extent of some other Rangers, since he does it mainly as a parody of 60s' Japanese daytime dramas.
Ship Tease: An early episode hinted that he might have romantic interest in Saki when he became worried about her spending time with a man outside the group (who, it turns out, she was asking for advice on how to defeat the Monster of the Week). He eventually gets heavy BST with Miu.
Beware the Nice Ones: Ren may be sweet but is not to be trifled with, as seen during GP 25 when he defends a Gaiark that he had believed for years was a sacred family statue, and in GP 35-36 following Sosuke's Disney Death
Idol Singer: GP 11 shows that this is a secret dream of hers. In GP 31, she forms an idol group (G3 Princesses) with Miu and Kegareshia in order to defeat a MOTW that functions on sound waves.
Ship Tease: It's occasionally hinted that Hanto has a crush on Kegareshia (in GP 14 he falls for her while she is disguised as "Rena", and in other episodes he seems to find her attractive even in her usual form.) Some fans also interpret his relationship with Gunpei this way.
Wholesome Cross Dresser: In at least two episodes. Later, in GP 47 Gunpei wants Hanto to dress as a girl and pose for fake wedding photos to deceive Gunpei's mother, despite the presence of two actual women on the team.
Cloudcuckoolander: Somewhere down the road, a few braincells dropped dead. By Shinkenger vs. Go-onger, any sanity he might have left was apparently on vacation.
Jumped at the Call: Desperate to become a Go-onger to the point of stealing the Engine Casts. It's only when he agrees to hand them back that Bomper decides Gunpei has a strong sense of justice, and allows him and Hanto to become Go-on Black and Green.
Ki Attacks: Ganga Ganga Dan, during the events of Go-onger vs. Gekiranger.
Terrible Artist: He is terrible at drawing. In GP 16, we see his drawing of a penguin, which looks like anything but.
Hiroto Suto/Go-on Gold | Actor: Hidenori Tokuyama
The Ace: One episode has a bunch of Hiroto's groupies saying he could master anything, and I mean anything, if he wasn't devoting his time to fighting Gaiark. And you get the feeling they're right.
Hey, It's That Guy!: Hiroto's actor, Hidenori Tokuyama, had previously played Sou Yaguruma/Kamen Rider TheBee/Kamen Rider Kick Hopper in Kamen Rider Kabuto.
I Work Alone: Initially. He later warms up to the rest of the team, but he and Miu live separately from the Go-ongers.
Spotlight-Stealing Squad: He and Miu got a lot of screentime for just two people. Justified because the Wings function as a separate unit from the Go-ongers
All Girls Want Bad Boys: While Sosuke is brainwashed in the Straw Banki episode, he begins acting like a gangster/Yakuza and offers Miu a stolen ring, which makes her happy. Later, after he has returned to normal, she admits that she preferred him brainwashed.
Aloof Ally: At first, but she warms up to the Go-ongers much faster than Hiroto does
The partners of the Go-Ongers, hailing from the Engine World. In order to survive on Earth they need to separate into Engine Casts, miniature versions of their true Engine forms, and Engine Souls, which are cartridge-shaped objects that store the soul of an Engine. When the Engine Casts are reunited with the Engine Souls, the Engines are brought back to full size for ten minutes, after which they risk rusting.
Verbal Tic: Either a syllable of their respective names or an associated onomatopoeia. Even the non-speaking Prehistoric Engines hsve their roars counted as these by their verses in the ending.
You Look Familiar: In the final episode, Nao Oikawa appears as a customer at the bakery where Saki now works, reminding the audience eerily of Kegareshia...
Air Pollution Minister Kitaneidas | Voice actor: Mitsuaki Madono
