The Hero: Although he rarely, if ever takes on the dominant role of leader, and even then under protest.
Law of Chromatic Superiority: Averted - despite getting a Cool Bike only for himself, he's the first Red Ranger in years to not get a Super Mode. He gains a second master last and earns his Master stripes later than Lily and Theo.
Took a Level in Badass: In the finale, he takes down a crowd of Mooks. While unmorphed. And proceeds to go one-on-one with the Big Bad without dying horribly.
Theo Martin / Jungle Fury Blue Ranger | (Actor: Aljin Abella)
My mind is a well-oiled machine. It can juggle two jobs, read a book and save the world - all before the lunch rush.
Actor Allusion: Possibly unintentional. In Jungle Fury Theo has a twin brother. The actor who played his Gekiranger counterpart has a twin brother himself. He even appears in an episode as an evil mirror version of his brother's character.
Ascended Fanboy: "No way! Ever since I was a little kid, I always wanted to be a — if that's what it takes."
Composite Character: of Gekiranger's Gou (Geki Violet) and Sha-Fu even though the latter's counterpart is Master Mao but since Mao dies in the first episode many of Sha-Fu's early stuff gets shifted to R.J.
Big Brother Mentor: He's far more social and "one of the guys" with his charges though, possibly because he was probably the youngest Mentor until Power Rangers RPM.
Iron Woobie: Non-dramatic version: she goes through a lot of work-related crap even before learning who her workmates really are. While a straight comic relief would either laugh it or be ignored by karma, she does get the chance to vent her frustrations.
You Have Failed Me: He strips Whiger of his Rinzin, title, and rank and banishes him from his temple as punishment for his defeat by the hands of the Jungle Master Stampede Formation.
You Have Outlived Your Usefulness: He allows the Rangers to destroy Carnisoar and Grizzaka and the Phantom Beast Generals to destroy Jellica because they are no longer needed by him now that he has learned to harness his hatred and deceit thanks to Carnisoar and Jellica and has learned Zocato on his own.
Smug Super: His arrogance about his immense power and his claims to be completely invincible are good reasons why he counts as one.
The Starscream: He steals Dai Shi's throne from him because he blames him for losing the great Beast War, and even more for inhabiting a human body. Dai Shi later returns to take his throne back.
This Cannot Be!: He screams this after the rangers destroy him with the Jungle Master Stampede Formation.
This Is Unforgivable: Before his huge battle with the Rangers, he declares to them, "You destroyed all my warriors, my royal guards, and the great Overlord Carnisoar. Finally, I shall destroy you!"
Unstoppable Rage: Even Dai Shi and the other villains are wary of pissing him off.
We Meet Again: He says this verbatim to the Rangers before their huge fight in his last episode appearance before the finale.
