Heartbroken Badass: He never knew his parents and eventually realizes that they're dead. Still, he never stops fighting for the good of mankind and nature.
The Hero: Leader of the Wild Force Rangers and the first 26 episodes mostly revolve around him learning what happened to his birth parents.
Hurting Hero: He grew up in the jungle, knowing nothing about where he came from. As a Ranger, he later learns his parents are presumed dead. He then learns they are dead and were killed by their friend, Dr. Adler (who became Master Org). Cole demonstrates considerable restraint in killing Adler when he had the chance.
Idiot Hero: To be fair, he grew up in village as far away from modern civilization as possible so such things like not knowing motorcycles are not alive is justified.
Large Ham: He stands out with his overly serious lines during the Red Ranger Reunion episode, in stark contrast with his predecessors' more relaxed deliveries. Even Carter was more laid back in comparison.
What Kind of Lame Power Is Heart, Anyway?: Played with. He realizes as early as the first episode that his abilities to commune with the hearts of creatures isn't especially useful in battle. That said, it does come in handy a few times during the course of the season.
You Killed My Father: Averted. Probably because he never got to meet his parents, he chooses not to kill Adler for it because he doesn't want to be obsessed with someone he hates like Adler was.
Taylor Earhardt / Yellow Eagle Ranger | (Actress: Alyson Kiperman)
Ace Pilot: She was one in the air force before becoming the Yellow Ranger.
Action Girl: The most experienced of the main five Rangers. She lasted longer than any of the others when Zen-Aku first appeared.
Faking the Dead: Her backstory for how she became a Ranger. The Animarium called her by crashing her fighter jet, and the only way she could be a Ranger (due to her status as a military pilot) was for her to let everyone think she had died.
The Lancer: She used to be the leader until Cole arrived. She doesn't like it at first until Cole proves he's capable of leading the team.
Meaningful Name: She shares the same last name as Amelia Earhardt, a female pilot who disappeared after her plane went missing. In this case, Taylor had to fake her death to become a Power Ranger.
Military Brat: Her Air Force days left her very devoted to rules and regulations.
Quickly Demoted Woman: The series started out with Taylor as leader of the team. When Rookie Red Ranger Cole shows up and is declared leader, Taylor isn't thrilled and spends at least another episode still trying to hold on to that command before giving up and letting Cole take control.
She's a Man in Japan: Along with some other Yellow Rangers in the franchise - in her case, her counterpart is male Air Force AWOL Gaku Washio. She is, so far, the last one.
Shipper on Deck: Is the first one to point out the tension between Princess Shayla and Merrick. Then ends up on the other side of this with Eric in "Reinforcements From The Future."
Tsundere: Watch the crossover with Eric from Time Force, "Reinforcements from the Future", and you'll understand. This was her attitude with the other rangers at first before eventually calming down. Complete departure from the Yellow Rangers before and after her, who are usually cheerful and friendly.
Max Cooper / Blue Shark Ranger | (Actor: Phillip Jeanmarie)
The Big Guy: Even without his ranger form's bison strength, he's physically stronger than his friends.
Did Not Get the Girl: For two episodes he's in love with a florist he used to work with named Kendall. In that second episode, she finds out he's a ranger, fully supports him and returns his affections. Unfortunately, because of his ranger duties, she turns him down.
Well Done Daughter Girl: Her father wanted her to inherit the dojo, but she wanted to go to College to be a teacher. Despite this, she wants her father's approval. He stops regretting his decision to let her go when he finds out she's a Power Ranger. Unlike other times in the series when this happens, she doesn't find out.
Merrick Baliton / Lunar Wolf Ranger | (Actor: Phillip Andrew)
Aloof Ally: Out of shame (and some general stoic-ness) rather than any actual dislike.
Greater Scope Villain The original Master Org doesn't confront the rangers due to his powers being used by Adler. After Adler is killed by Mandilok, he grows a horn and comes back to life. He eventually returns and kills Mandilok in revenge. He then talks as though he and the original are now one and the same.
Roaring Rampage of Revenge: His backstory has him murdering Cole's parents out of jealousy, which he called his "rightful revenge". Toward the end of the season, he also engaged in this to make those who betrayed him pay.
Was Once a Man: Early on, subverted; but then the real Master Org came and took over Adler fully.
We Used to Be Friends: He used to be good friends with Cole's birth parents and fell for Cole's mother. He wanted to propose to her, but Cole's father beat him to it. Neither were aware of his feelings for her or that he grew to hate them for what he perceived as stealing his love and his work long before he became Master Org.
Took a Level in Badass: He starts out as a manipulator who remains in the shadows. By the end of the series, he destroys all of the wild zords and comes very close to winning.
Villainous Breakdown: Desperately trying to get the favour of her master, General Mandilok, she's convinced of cutting her own horn in order to succeed in kidnapping Princess Shayla without fearing being killed by the Animarium's fountain. She later learns that horns don't grow back, yet still pledges loyalty to her master, obsessed with his approval. Then her efforts are dismissed as Mandilok uses her to shield himself from the rangers' attack.
Woman in Black: Her usual attire and her stealth suit from "The Master's Herald". Even her human disguise featured black.
Zen-Aku | (Voice actor: Dan Woren before being separated from Merrick, Lex Lang later)
Enemy Within -> Enemy Without: He was the spirit of a mask that Merrick stole from the Org General Nayzor to battle Master Org, knowing full well wearing it would turn him into Zen-Aku. Wearing the mask is while trapped in a tomb is what kept him alive. After the mask is destroyed, Zen-Aku reveals he no longer needs a host and starts going after Merrick.
Lightning Bruiser: Zen-Aku is capable of moving at lightning speed and uses his crescent blade to slash the Rangers. It seems to be his signature attack.
Noble Demon: When Alyssa was injured, he nursed her back to health instead of attacking her.
Noble Wolf: While an antagonist, he is not out and out evil as the orcs and instead is a Noble Demon. He never causes public chaos, did not destroy an unconscious Alyssa, doesn't allow the rangers to interfere with a duel between Taylor and another org, and even protects a dog. At the end of the series, he and Merrick are traveling buddies seeking redeemtion.
Savage Wolves: An antagonistic wolf and, when Merrick first puts on his mask, he says "Evil spirit of the wolf..."
Mandilok | (Voice actor: Barbara Goodson as the female voice, Esra Weisz as the male voice)
Ambiguous Gender: Since Mandilok has two voices, one male and one female. Lampshaded when Jindrax doesn't know whether to use "sir" or "ma'am" when addressing.
Big Eater: It's overall goal is to eat whatever it finds, whether it be be buildings, food or even people.
The Starscream: Took over as leader when Master Org turned out to be a fake, and killed him. It doesn't last.
Ungrateful Bastard: After Toxica and Jindrax free it, Mandilok treats them with no respect, even temporarily replacing them with new duke Orgs.
Greater Scope Villain: They gave Ransik his powers in Time Force, which led to his rise as the greatest criminal of the future.
Original Generation: They are made of bits from suit of previous Ranger villains and monsters. Originally, they were to be represented by Orgs from the Gaoranger movie, but the suits were destroyed in a fire.
No Name Given: They aren't referred to by name in the show. They are revealed in the end credits as Takach, Kired and Rofang (named after three Power Rangers fans who ran a website).
