Lethal Chef: She doesn't think so, but the rest of the Rangers attest otherwise - though like with Mako, they're too polite to do so to her face (Kevin, for example, has the decency to throw away her burnt chicken while she's not looking). Fear is another possibility. We've seen her use her Samurai katana to slice a squash to bits, they might just feel it's not smart to offend somebody with samurai training and easy access to knives.
Negatron proves she is at least afraid she is. The insult he used to send her flying was "lousy cook", and she later asks everyone if she really is that bad. As stated before, they deny it not to bring her down more.
Even Emily is wary of her cooking (remember that, in the original, Kotoha thought Mako was flawless even in this department); in "Team Spirit", she goes so far as to cautiously ask if it was Mia who baked her birthday cake.
Noodle Implements: We never learned what she was planning to cook, but we do know it involved combining oysters, chocolate sauce and Brussels sprouts in a very specific way.
This Is Unforgivable: In "Deal with a Nighlok", she and Kevin both hear Doubletone out when he explains that his plan was to get Ryan to give up on his dream of baseball by convincing him that doing so was the only way for him to see his daddy again, just so he could get him to cry and enjoy it. Not one to take that well, she says this trope to Doubletone himself.
It's Not You, It's My Enemies: A platonic case. Because of his Ranger duties, Mike has to tell his friends he won't be able to hang out with them for a while. Additionally, it's implied that all the Rangers are forbidden to see their families until the enemy is defeated for this very reason. It's mentioned he even had to skip his graduation.
Iaijutsu Practitioner: Antonio mastered this way of fighting - self-taught with a Reverse Grip no less. It's taken Up to Eleven here: his quickdraw ability is such that by resheathing his sword after each strike, he is able to spam it, making a dozen strikes before he even appears to have done anything.
Eleventh Hour Ranger: An odd variation, as she actually replaces Jayden as the team's leader, rather than straight-up joining the team. Subverted when she's hurt and gives the job back to Jayden before the true final battle.
The Spartan Way: Emily remarks that she must have 'trained night and day' to become so skilled a samurai. She replies this was more or less the case: train, exercise and practicing the sealing power was her life from early childhood.
Butt Monkey: Poor Bulk. He just doesn't catch a break sometimes.
Both of them, really. Bulk tends to abuse Spike and the universe tends to abuse Bulk. Skull gets in on it, too, both giving and receiving abuse in his cameo scene.
Call Back: In episode 3, Bulk wears clothes similar to what he wore in the old days, namely a jean vest and a bandanna.
Demoted to Extra: At least, in comparison to Bulk with Skull in the good old days. They've only occasionally gotten caught up in monster attacks and have almost never interacted with the Rangers in their civilian identities. That said, it's still better than Bulk's handful of cameos in Power Rangers Lost Galaxy.
Hopeless Suitor: Spike likes the Pink Ranger - like father, like son. Only in Skull's case, he had a crush on the girl not knowing she was the Pink Ranger. Spike initially focuses on the Pink Ranger herself without knowing who is wearing the helmet and suit. He later meets and gets a crush on Mia out-of-morph, forming a Two-Person Love Triangle of sorts... with Mia herself being none the wiser.
Secret Keeper: Knows why Mia had to leave home, and who the other Rangers are. While it's been unusual in the past for siblings to know that their brother or sister is a Power Ranger, it's explicitly a lineage-based thing this season, so it's not so out-of-place.
Scott Truman / Ranger Operator Series Red | (VA: Tobias Reiss aka Eka Darville)
Authority Equals Asskicking: He's dealt with Nighlok trying to usurp his thrown with relative ease, has proven more powerful than Serrator, and when he finally comes out himself in "The Master Returns", he beats the hell out of the Rangers with absolutely no effort. While drying out! It's clear the Rangers would be in deep trouble if he could actually leave the Sanzu River.
Big Entrance: In "The Master Returns", his arrival on the human world is accompanied by a storm blacking out the sun, and rocks assembling themselves into a door with red light shooting out of the gaps that explodes when he emerges from it.
Orcus on His Throne: Normally he doesn't do anything except yell at people. The Rangers don't even seemed all that concerned with him in particular even though he's supposed to be the Big Bad. This is completely in-character with his Sentai equivalent. He has gotten off his duff and attacked Deker for "meddling in his affairs" that concerned the Red Samurai Ranger, if that counts for anything and he also attacked a Nighlok who had been scheming to overthrow him.
In "The Master Returns" we find out why he's not taken action himself: the moment he steps foot on the human world, he begins to dry out so badly it takes him out of commission for some time.
Roaring Rampage of Revenge: After learning Serrator had been deceiving him, he comes to earth himself and proceeds to go on one of these. The only reason he didn't wipe out everyone then and there was he dries out much more rapidly than a normal Nighlok, forcing him to retreat.
Sealed Evil in a Can: Was sealed in the river by Jayden's father. Due to the seal being done wrong (which stems from the previous Red Ranger having insufficient power at the time), it causes him headaches.
"The Master Returns" seems to imply that he's still trapped to some degree, as flashbacks show he could previously leave the Sanzu River without drying out, a problem he has now.
Villainous Breakdown: Nearly tears the ship apart in a blind rage when he discovers the Red Ranger is the one who sealed him away and Jayden could do it again. He gets so furious, it causes enormous numbers of Mooks to spawn and it takes a much larger dose of his "medicine" to settle him down.
Octoroo | (Voice actor: Jeff Szusterman)
Badass: Held his own in a straight up fight with both the Red and Gold Rangers.
Deal with the Devil: Sold her soul to save Deker's life. She wasn't told until after the deal was complete that she doomed Deker to become a half Nighlok and forget her forever.
Despair Event Horizon: After Deker is killed for good, she loses what little hope she had left of being with him again. In response, she uses the sadness in her music to revive Master Xandred so he can destroy humanity, as she has lost everything but her status as a Nighlock.
Happily Married: She and Deker were a married couple until a fire came down and killed Deker...and now Deker doesn't remember her.
Hidden Depths: In "There Go the Brides", she seems to have bad wedding memories that motivate her to carry out the episode's plot; and "The Blue and the Gold" and "The Tengen Gate" hint that she and Deker have some history.
She crosses the Despair Event Horizon when Deker is killed, causing her to resurrect Xandred so he can wipe out humanity. In her own words, it's because she's got nothing left but being a Nighlok without Deker.
Dragon-in-Chief: Takes control of the Nighlok forces for most of his tenure and is much more competent a general than Xandred bothers to be. The only catch is that Xandred remains a very, very large physical threat.
Early-Bird Cameo: Twice, oddly enough. First was in Dayu's memory/dream in "Broken Dreams", and later in the flesh in the early-aired "Clash of the Red Rangers".
Knight of Cerebus: The series wasn't exactly lighthearted, but Serrator and his Nighlok are even more viscious and vile than those that came before. Not only that, he's one of the most powerful enemies the Rangers have faced thus far.
Kick the Dog/For the Evulz: In his official debut episode, "Something Fishy", in order to show his power to Master Xandred, Serrator destroys an entire army of his own moogers.
Later admits to Dayu that he thoroughly enjoyed the Deal with the Devil he made with her to save Deker's life, ruining both their lives in the process.
Mook Maker: Seems to be able to spawn Moogers, like Xandred. Can also use his claws to cut a sheet of paper into the giant Papyrax.
Sanity Slippage: After Deker betrays him, his normal composure dissolves and he goes from a meticulous Chessmaster to The Berserker, firing randomly in all directions and single-mindedly attempting to destroy the Rangers. Even after going Mega Monster and recovering some of his composure, his voice is noticeably deeper and more unhinged.
This Cannot Be!: His reaction to Xandred coming to deal with him personally.
Has a far more serious one when Deker betrays him.
Villainous Breakdown: After Deker betrays him, he goes completely insane, firing randomly in all directions and his normal Evil Laugh becoming even more unhinged. While he recovers somewhat during his Mega Monster form, his voice becomes slightly deeper and more unhinged.
Wolverine Claws: While his fingers are pretty damn sharp already, he can also enlarge his entire hands for more power, as seen in his first scuffle with the Rangers.
Conservation of Ninjutsu: The Moogers' difficulty seems linked to the number of them. In "There Go the Brides", a small group of them are able to give the Samurai Megazord a good deal of trouble without a Nighlok backing them up, where the larger groups normally supporting the Nighloks are taken out much more easily.
Covered In Slime: Antberry, to the point where it spills over to nearly everything he touches.
Deal with the Devil: Doubletone's whole schtick is making (and later breaking) promises in exchange for his victim giving up his/her dream.
Detachment Combat: Taken to an extreme with Splitface, who can explode into dozens of ricocheting spheres. Mike described it as being "like dodgeball with teeth".
HalloweenVillain Episode: "Party Monsters", a Clip Show which focuses on the spirits of the deceased Nighloks and Moogers throwing a Halloween party and trading war stories about their battles with the rangers and how they were defeated by them.
In "Jayden's Challenge", we're introduced by Robtish to Flying Giant Moogers.
No Name Given: The umbrella-headed Nighlok in "Forest for the Trees". SamuraiCast.com lists him as Desperaino, which is used in "Party Monsters".
One-Winged Angel: In his second life, General Gut starts out like he looked in his first life, but when the Battlewing Megazord lands what appears to be the fatal blow on him, he goes from his overweight golden form to a much more in-shape blue form with a neck-extending serpent attached to his crotch.
Smug Snake: Madimot likes to call himself the "baddest of the bad." Needless to say, he's not as much of a threat as he believes he is.
Smug Super: Armadeevil loves his nearly-impenetrable shell so much that he simply won't hesitate to tell you his beliefs that he's completely invincible and tell you that you lose to him, no matter what. The Rangers prove him wrong when they destroy him both times.
General Gut loves calling himself a great leader, and it's not surprising that he's one of Master Xandred's best warriors. He even believes that the serpent attached to his groin in his One-Winged Angel form is indestructible... and the rangers prove him wrong when the Sharkzord bites it off.
The Speechless: After Arachnitor is mutated for his treason, he lost his ability to speak, which led us to a battle almost free of wisecracking.
The Starscream: Arachnitor is an interesting example of a Monster of the Week that actually tried his hand at becoming Starscreamy to Master Xandred. Sadly, his attempt to overthrow him and become the new leader of the Nighloks didn't end so well for him, and he ended up being mutated through Cold-Blooded Torture as punishment for his betrayal.
This Cannot Be!: General Gut screams this when the Sharkzord severs the serpent attached to his crotch from it.
General Gut: IMPOSSIBLE! That serpent was INDESTRUCTIBLE!
Madimot says something similar when finished off by the Tiger Drill Megazord. "I can't be beat! I'm the baddest of the bad!"
Toilet Humor: "Moogers" looks and sounds an awful lot like "boogers", doesn't it?
Threatening Shark: Sharkjaw, though he only appears in the very beginning of "Clash of the Red Rangers"
