Combat Pragmatist: The aforementioned using a Humvee on a demon (yes, on his first day as a Ranger, the first thing he does is ACTUALLY trying to run over the Batlings and the demon using the Humvee), and actually bringing a gun to shoot down mooks in "Forever Red" (thus averting Why Don't Ya Just Shoot Him?).
Thus, it can be argued that in comparison to most of the Red Rangers, he's the one that took the most initiative and he was a quick-thinker (by no means does that mean that the other Red Rangers were dumb — but, most of them tend to be very indecisive, become very neurotic when they despair, and/or be very impulsive and wreckless). If anything, he actually kept a fine balance between being headstrong and using his brain.
Law of Chromatic Superiority: He gets a special sidecar to his bike, a special vehicle (see above). Somewhat subverted when Joel and Chad get their Super Modes ahead of him, but played straight when he gets a second Cool Bike (which doubles as a Battlizer) near the end of the season.
'90s Hair: "Curtained hair", to be specific; kinda like Leonardo Di Caprio's in Titanic, or Nick Carter's 90s BSB hair. Though the show originally aired in 2000, "90's hair" was still in style (given that we had just came out of the 90's when 2000 came) in the early 2000's. Sean CW Johnson no longer sports this hair, of course.
Odd Friendship: With Kelsey. Pretty reminiscent of the friendship between Billy and Trini from the Mighty-Morphin' days. Coincidentally (or not), the color of their respective suits match that of Billy and Trini.
Out-of-Character Moment: It was well established that Dana was an intellectual and was level-headed. However, she is given her out-of-character-moment in the episode, "In the Limelight", where she suddenly becomes narcissistic... as if she made a complete 180. It was highly unusual because past episodes have never implied that she had such tendencies. Of course, it would be very understandable how she might become anxious and desperate about getting into med school considering how she is an A-student and cares a lot about her studies, and the fact that she is balancing her Ranger duties on top of that. But again, her insecurities (assuming that she did have some) and the pressures she could be feeling were not given much focus; instead, we get what looks like a rushed, let's-just-throw-this-in job on the writers' part. Here, she is just simply made to look like someone who is very quickly taken over by vanity.
Near the end of the episode, however, she realizes her mistake and genuinely feels bad, subsequently ditching her modelling (finding that it really wasn't for her) and everything going back to normal.
Reports of My Death Were Greatly Exaggerated: Everyone thought he died in the car crash. Except for Captain Mitchell, who remembers watching in horror as Diabolico's spirit comes in to save Ryan from falling to his death from the cliff — only to raise him so that his mind is poisoned, is added to the list of henchmen, and so that he turns against his father and sister.
Retired Badass: he used to be a firefighter, and once saved a young Carter from a burning building. In "A Face from the Past" he demonstrates that, despite being retired, he still got the skills for the job.
The Only Way They Will Learn: At times, it can be a bit frustrating when he doesn't always give straight answers, especially when he is being vague. But in the end, he does want the Rangers to learn and to think for themselves. Notable examples:
In "A Matter of Trust", rather than letting her go with the rest of the team on a mission, he sends Dana on an seemingly unimportant errand to pick up a fishing buddy of his. Naturally, she gets mad since he doesn't explain why right then and there. But then... perhaps it was best that she and the team find out later that his friend was the one who was actually carrying the real fuel cell — while her friends were guarding (albeit, unknowingly at first) a decoy. Why, you might ask? Well, since he planned for the other four Rangers to act as distractions, to help buy time, they had to do their job very well to pull it off; and to do that, they had to act naturally (by thinking they have the real fuel cell) and as if they are guarding the real thing — that way, they don't look suspicious. Think of it as being akin to Enforced Method Acting. And boy were Vypra and her henchmen in for a surprise when they find out too late that they've been chasing after the wrong car. More importantly, however, Dana learns that sometimes you just have to go with your gut when some answers just aren't always obvious or when some things just seem to defy logic.
In episode 3, "Trial By Fire", Carter gets the fastest time on the stopwatch but the lowest score during a training session. He begins to question his abilities as a Ranger and starts losing confidence. Later in the episode, Carter gets mad at first when he is told, without explanation, to put out the fire first before rescuing a kid. Turns out, there was some combustible gas in the building, which could have exploded and killed a lot of people. He then goes back to re-examine his training spots, where he [blindly] shot targets, and sees that a lot of his shots had landed dangerously on, you guessed it, combustible materials. Overconfidence seems to have gotten to Carter for a while there and it almost impaired his good judgement. From then on, and thanks in part to Captain Mitchell, we see Carter consistently keeping a cool head for most of the season.
Dr. Angela Fairweather | (Actor: Monica Louwerens)
Fake Boss: Rangers thought he was the true leader of the demons when it looks like he's gone for good, they thought wrong. Interestingly, it parallels how they thought the first monster they fought was him too.
Hoist by His Own Petard: That Star Power he was so fond of got turned against him, when he blasted the Lightspeed Solarzord and it absorbed all of, and sent it right back at him.
Magic Staff: Wields a big one. He drops it when he dies.
Ascended Extra: After all of Banshera's main generals were defeated/killed, Jinxer were briefly promoted to become this thanks to the fact that he still have use before he was destroyed along with the Omegazord.
Weaksauce Weakness: Like all of his kin, to water. It takes away most of his powers, forcing him to relay on the usual Rangers villain tactics.
Queen Bansheera | (Voice actress: Diane Salinger)
Ascended Extra: Her counterpart, Gradienne, was (at least physically) destroyed by the Go Go V before the series finale. Instead of her, a revived Salamandes and Zylpheeza served as the final opponents (though they were controlled by Gradienne's spirit during that fight). In Lightspeed Rescue, Bansheera stays around till the very end and is actually the final villain the rangers have to fight. She plans to use an eclipse to open the gateway to the Shadow World before being sent their too by Carter(and Diabolico).
Bad Boss: One of the worst bosses in Power Rangers history.
One-Winged Angel: She becomes this after absorbing Vypra near the end of the series.
Orcus On Her Throne: Subverted. She doesn't do anything directly against the Rangers until the very end of the season, but it's because she can't. The Rangers interrupted the demons' ritual to bring her back, leaving her in a deformed, far less powerful body. It is not until she absorbs Vypra in "Wrath of the Queen" that she regains her full body and powers, and it is then she begins to take a far more active role in achieving her goals.
