Vitriolic Best Buds: They will insult each other every now and then but when shit hits the fan, they will stick up for each other.
Sean O' Callahan / GPX Red
Nationality: AmericanHometown: ChicagoThe leader of the GPX Rangers, Sean is the former captain of a junior ice hockey team. Due to the fact that he became Red Ranger instead of Daisuke, the two have a hate / hate relationship. Initially skeptical, he eventually warms up to his job and comes to embrace it (or, in his words, "have hot, sweaty sex with it"). Unlike many Red Rangers, he's hot-headed, temperamental, foul-mouthed and rude. However, he makes up for it by being not just an inspiring and effective leader, but by warming up to his teammates.
A Man Is Not a Virgin: Hilariously averted, since he is a virgin and only had one kiss in his entire life (Maria did kiss him in an earlier episode, but it was a "Shut Up" Kiss and Maria says it doesn't count).
But also a positive aversion, since even though he's a virgin, he still kicks ass.
Break the Haughty: Prior to episode 13, he had been a jerk to everyone else, and even Daisuke, but Daisuke's mutiny and eventual beat-down by Phaedos forces him to undergo obvious Character Development.
Nationality: IrishHometown: DublinA friend of Sean's prior to coming to Tokyo. He is a former member of the Irish Defense Forces. He acts sort of as a counter for Sean. He's a good second-in-command who has good leadership skills, although the others don't follow along, much to his irritation. Recent Character Development is showing his intellectual side, including his becoming a teacher in an alternate universe.
The Aragorn: Has shades of this in SIU due to his job as a TA, which prevents him from seeing the others outside class, so he's not with them as much except on Ranger duty. He also gave orders when Sean was incapacitated.
Nationality: South AfricanHometown: JohannesburgDaisuke's replacement as the Green Ranger. He's a college student who seemed reluctant to be a Ranger. He wants to help out the people of the townships, but Ranger duty interrupted it. He tends to be more sarcastic and irritating to Sean, more of a combative Lancer than Kevin, but unlike Daisuke, he's not rebellious.
Achilles in His Tent: He temporarily leaves the Rangers and lets Daisuke take his place. Then he comes back and helps the Rangers out in the climax.
Nationality: JapaneseHometown: KyotoThe older of the Miyazawa siblings. The son of a wealthy family, Daisuke had been promised a position of leadership in the Rangers. However, he is angered when Sean is made Red Ranger. Eventually, after the other Rangers are nearly killed, he recognizes his flaws and leaves the team. Due to his upbringing, he's aloof and looks down on the others until his departure.
Politically Incorrect Hero: Played with. He doesn't like Westerners and it's emphasized a little more in the reboot, but his hatred of Sean for taking his Red Ranger spot is still his main reason for hating him.
Pride: Arguably his Fatal Flaw. He believes he should be the leader, and thinks that a middle-class fool like Sean does not deserve to be leader.
Small Name, Big Ego: A less comedic version. he thinks he can lead, but he freezes up whenever something bad happens. This allows Sean to become leader.
Spoiled Brat / Royal Brat: He's a modern, non-royal version of this trope. Possibly deconstructed, since his selfishness not only splits the team up, it nearly gets them all killed.
Take That: He's pretty much a Take That aimed at Japanese nationalists and entitled rich folk.
"The Reason You Suck" Speech: Gives one to Sean and is on the receiving end of one from from his sister. He's later on the receiving end from Sean.
What the Hell, Hero?: On the receiving end of several of these. The first is when he he nearly fires on civilians, the second is when Hitomi yells at him and third when Sean decks him for his behavior.
Would Hit a Girl: Especially if they're a complete bitch and she's threatening his sister.
Maria Aparicio / GPX Yellow
Nationality: VenezuelanHometown: CaracasFull name Maria Juanita Aparicio Rodriguez. The first lady to be introduced. She's a tough, no-nonsense lady from Venezuela (but has been living in Brazil for the past 3 years for unknown reasons) with a sarcastic streak. She acts as the reasonable figure of the team. She acts as Hitomi's best friend within the team and acts a third leader at times. She's also Bi.
Nationality: JapaneseHometown: KyotoThe other, younger Miyazawa sibling. Unlike her brother, she doesn't have much of an ego, instead trying to make friends with Sean, Kevin and Maria. Unfortunately, she has confidence issues that tend to compromise her fights. She's an energetic young woman who can come across as a Mary Sue, but a little push can bring out her dark side. While she can be naive, she is also a very intelligent young woman.
Cuteness Proximity: Along with Maria, she goes ga-ga over Sean's baby niece. Lampshaded by Sean.
Extreme Doormat: For some reason, Daisuke is able to get her to follow him, which shocks the other Rangers. She gets better and stands up for herself. It later turns out she was hypnotized and programmed to become this if Daisuke says a certain phrase.
Yaoi Fangirl: Implied and played for laughs at the same fucking time.
Robert "Rob" Jackson/GPX Silver
Nationality: AmericanPlace of Residence: Orlando, Florida/Carbondale, Illinois/Madison, WisconsinBridget's husband and Sean's brother-in-law. He hasn't been developed yet, so tropes are coming. Eventually, it's revealed he's the Silver Ranger. In GPX SIU, he is an SIU police officer. He tries to act reasonable, but his inexperience as a Ranger sometimes betrays him. Unlike the others, he was not trained by Project Ranger, but was considered for it, but was too old for the Project. However, Marine training more than makes up for it.
Semper Fi: Initially it makes Hitomi a little uncomfortable, but she gets used to it. He shouts "Ooh-rah" as the Silver Ranger, which tips Sean off to Marine training. In fact, his Marine experience helps the Rangers out in a way.
Shell-Shocked Veteran: Downplayed. He's suffering from PTSD, but he's trying his best to manage it. He mainly uses it to provide advice to the younger Rangers. Interestingly, the worst nightmares he's had are of the people he's killed, not his buddies getting killed.
Nationality: AmericanHometown: Chicago, IllinoisA GPX SIU-only character (at first), he's a friend of Sean's from Chicago and a former teammate. Well, not SIU-only anymore, as he now appears in Supercharged. Like Rob, he was not trained by Project Ranger and has very little knowledge of martial arts. However, he does his best to try. In Supercharged and by extension the main continuity, he is not a Ranger.
Nationality: AmericanHometown: Green Bay, WisconsinOne of Sean's teammates on the Badger hockey team, of full-booded Native American descent. He is soon discovered to be a Project Ranger trainee, although purely by accident. Just minutes after this discovery he's given the Gold Ranger morpher and joins the team. He's cold and uncaring at first, but it's later revealed that he has a more dorky and high-strung personality.
The muscle of the Zordonians. He thinks almost entirely of destruction, never thinking about anything but smashing things. He fights the Rangers from time to time, getting beat only once. Unlike the other Zordonians, he's not based on any other Sailor Moon villain.
Manipulative Bastard: If he really is behind Ben Dreck's anti-Ranger positions, then this might be the case.
Paper-Thin Disguise / Clark Kenting: Strangely averted. his German accent is mentioned to be pretty convincing. Plus, he took the place of an already-existing person named Marcus Schneider... whom he had killed.
Badass Pacifist: She doesn't even fire a shot or throw a punch and she still gets elven soldiers to put down their weapons.
Bigger Bad: Although she lets Ragnar do his job. Although, that may not be the case anymore.
Broken Bird: Her brother's death has left her depressed, lonely and suffering from Separation Anxiety.
Character Development: She's starting to outgrow her earlier depressed state, and is becoming more of a leader, as shown when she gave Sean a pep talk after he realized the Rangers were killing monsters.
A field general for the Ouroboros Society. He's the first enemy the Rangers face in the new semester. However, after failing time and time again, he tries to get revenge on the Rangers... and dies in the process.
