In #2, it's implied that this happens whenever he panics at all; it just so happens that chickens freak him out.
And in #3, just the word is enough to cause some difficulty. While not freezing him up completely, it does slow him down, resulting in more effort being required in order to move.
Ryūji Iwasaki/Blue Buster | Live Actor: Ryouma Baba
Cunning Linguist: He is apparently fluent in French (as he can understand Enter perfectly) and English (he can effortlessly read an e-mail written in English). Frequently translates for Enter to the rest of the team.
MMA Fighter in All of Us: When fighting the Copyroid, Ryuuji applies a cross armbreaker to disable the Metaroid's camera arm (and thus, its copying abilities).
Overheating: What happens if he uses his Super Power too much. Which then causes him to go into his...
Superpowered Evil Side: Overheated!Ryūji can curb stomp a Metaroid single handedly. He also has a noticeable sadistic streak and no qualms about attacking his teammates.
Also doubles as a Heroic RROD because of the strain on his own body.
It's reflected in his fighting style. Normal!Ryūji has a very elegant and technical fighting style. Overheat!Ryūji goes more into strength-based attacks that take advantage of his super power.
Just a Kid: Initially defied when Miho expresses this reaction only to have it made very plain to her that Yōko is in fact a crack agent. However, later episodes do portray her age and naivete as a weakness.
Good Is Not Nice: #4 has him make it very clear that he has no belief that the people trapped in hyperspace are still alive, and further is entirely willing to risk the lives of or outright sacrifice the Go-Busters if it would give him an advantage against the Vaglass to do so.
Operator Miho Nakamura | Live Actress: Fūka Nishihira
Promotion to Parent: Has been Hiromu's main parental figure since their parents were killed 13 years ago, explaining her over-protectiveness of him in not wanting him to join the other Busters.
Millennium Bug: It's not mentioned, but if you do the math, he was born towards the tail end of 1999 in December, though an exact date wasn't given.
Psychopathic Manchild: Is an extremely dangerous computer virus who, if released, could threaten the entire world, but he's also quite childish and tends to throw temper tantrums if he doesn't get his way.
Rule of Symbolism: His "birth" appears to have happened on Christmas Day.
Sealed Evil in a Can: Is imprisoned in subspace. His goal is to steal enough energy to finally be free.
Enter | Live Actor: Syo Jinnai
Beleaguered Assistant: Enter is quite competent in his job, but he has to constantly put up with his master's temper tantrums and some of his genuinely good plans tend to go ignored by Messiah. While loyal to Messiah, Enter has shown annoyance at having to essentially babysit him.
Berserk Button: As shown in #9, the man DOES NOT like being tricked.
Faux Affably Evil: Seems genteel and cultured, but when something's in his way, the gloves come off.
Shown in episode #4 when he is just sitting around, eating pizza when they show up. He proceeds to politely offer them some before creating a Metaroid to try and kill them.
French Jerk: Sorta. He may not actually be French (it's ambiguous whether he's even human), but with his heavy usage of Gratuitous French and his overall nastiness, he counts as one.
For the Evulz: Outright admits that while stealing enough Enetron for Messiah to escape subspace is the primary goal, some attacks are simply to amuse Messiah by causing human suffering. Enter himself seems to really enjoy what he's doing.
Genre Savvy: In the opening of #3, he proposes sending several Megazords at once to steal Enetron from multiple locations; however, because Messiah is throwing a temper tantrum (which threatens to collapse portals out of subspace), Enter drops his plan in favor of trying to kill the Go-Busters in a more conventional way.
He tries for the same general idea again in episode 7, creating a Metaroid that's specifically designed to gather a massive amount of Enetron, enough to send multiple Megazords at once. Furthermore, he specifically states that this plan is designed to combat Go-Buster-Oh.
Villain Exit Stage Left: In EVERY single episode. The Go-Busters never stood a chance fighting him directly.
Villainous Breakdown: In #9, he loses his cool for the first time so far when the Go-Busters outsmart him.
Vaglass Mecha
Averting the best known ofSuper Sentai tropes, Vaglass always deploys a man-high Metaroid, used to summon the massive Megazords from hyperspace while feeding them with vital data from the field.
Appropriated Appellation: The Energy Research group assigned their own classifications to the Megazord types, as seen below.
Pokémon Speak: Averted. That's just what the summoning process sounds like.
Shapeshifter Baggage: The resulting Metaroid will always be about the size of an average adult human being regardless of the size of the object it was transformed from.
Taking You with Me: The Sprayroid in episode 6 has no qualms about the fact the hangar he and the Busters are in exploding would kill him along with them, in fact he seems almost excited about it!
Verbal Tic: There are some Metaroids that imitate the sound of the objects that they are made from, like the Densharoid's clacking and Drillroid's whirring.
Made of Explodium: Averted with CutterZord as a way to indicate just how narrow the victory actually was. Played Straight when it's defeated by Go-Buster-Oh later on.
Wake Up Call Boss: The first Gamma to appear severely damaged Go-Buster Ace, successfully stole quite a bit of Enetron, and required Hiromu to take several potentially fatal risks in order to just barely defeat it. And even then it survives, allowing Enter to reactivate it, requiring the first formation of Go-Buster-Oh to finish off for good.
