- Battle Couple: He and Ashley Collins become this over the course of the first book, and stay together throughout the series — though they don't get married until late in the series.
- Cannot Spit It Out: He can't bring himself to propose to Ashley, mostly due to him being unsure of whether he'll be a good husband or remind her of her abusive ex.
- Crouching Moron, Hidden Badass: He's a government agent, but his slacker attitude initially belies this. Getting thrown into crises increases his competence, which he himself acknowledges in later books.
- Deadpan Snarker: He responds to most situations with sarcasm.
- Enemy Mine: He and Endo are forced to work together on multiple occasions, and Jon hates it.
- Hijacking Cthulhu: He temporarily takes over Scylla's body with Maigo's help.
- Nice Hat: Jon's trademark headgear is a maroon beanie which he uses to hide the fact he's going bald.
- Not So Different: He narrowly avoided being killed by his own father when he was a child, an experience that enables him to emphasize with Nemesis when he learns the truth of her past.
- Promotion to Parent: He takes in Maigo's clone at the end of the second book, and formally adopts her at the end of the third.
- Psychic Link: Following the end of the first book he possesses one with Nemesis, which is transferred to Maigo.
- Sex for Solace: How he and Ashley consummate their relationship, to recover from the trauma of Nemesis's first attack.

- Fiery Redhead: At least in the heat of action, she tends to be action-oriented.
- Literal Ass-Kicking: When pinned down, she knees Lilly in the backside to knock her off.
- Mistaken for Pregnant: Jon finds a positive pregnancy test in her trash and immediately assumes it belongs to Ashley. He berates her for trying to hide it from him in front of everyone before she manages to inform him that it actually belongs to Cooper, who wanted to keep it a secret from Watson.
- Sex for Solace: How she and Jon consummate their relationship, to recover from the trauma of Nemesis's first attack.
- Teeth-Clenched Teamwork: Initially she didn't care much for Jon, but surviving Nemesis' rampage together caused her to fall for him.
- Cowardly Lion: He's not a field man but ends up tossing bricks at a super-powered Gordon when he attacks their headquarters.
- Geek Physiques: He's quite obese and is their tech support.
- Mission Control: He stays at the HQ coordinating the on-field agents.
- The Smart Guy: He keeps the technology up to date and running, along with being closer to a sterotypical geek.
- The Lancer: While Collins is Hudson's hypercompetent fighting co-worker in the field it's Cooper that makes sure things run smoothly behind the scenes and handling, or cutting, red tape.
- Defrosting Ice Queen: As the DHS-P goes through its first real case, Nemesis, Hudson starts to see a softer side to her.
- Sugar-and-Ice Personality: She's normally aloof, but has a softer side that occasionally shows through.
- The Stoic: While she does have emotions, she doesn't usually show them.
- Ace Pilot: Dude can fly helicopters like nobody's business.
- Cool Old Guy: At sixty he's the oldest of the team, had a few tours in Vietnam, and is not afraid to constantly flying his helicopter very close to Kaiju. He also seems to respect Lilly more than Maigo, teaching her how to pilot the Cool Plane between books.
- Cool Plane: Well, helicopter. At first it's an old red-painted chopper, but after it's destroyed he gets a gift-wrapped military helicopter, painted red. In the third book he gets his hands on a prototype supersonic VTOL.
- Dirty Old Man: He started teasing Maigo about being a woman and is labeled 'dickhead' in her head when Jon and Ashley are 'father' and 'mother.'
- Older Side Kick: Sometimes gives advice like a parent, has first say when it comes to piloting but mostly follows the younger Jon's lead.
- Technologically Blind Elders: Averted he easily keeps up with different types of helicopters and has zero issues with a supersonic secret jet.

- Innocently Insensitive: He accidentally insults Lilly when they meet for the second time, prompting her to coldly leave him for dead.
- Promotion to Parent: He takes Lilly in after the events of Island 731.
- Properly Paranoid: He's paranoid that the DARPA and G.O.D. won't stop looking for him and Lilly. He's right.
- Scarily Competent Tracker: He was thoroughly trained in tracking and hunting by his foster father, and became a park ranger.
- Suicidal Overconfidence: He took on a grizzly bear that he could have let walk away. He won, but the bear nearly killed him and gave him a nasty scar on his chest as a reminder. Howie gave him a What the Hell, Hero? speech that led to him taking a sabbatical to find himself.
- The Straight and Arrow Path: Used a bow and arrow to fight Gordon in Project Maigo seemingly useless but each arrow was actually explosive.
- Action Girl: She has superhuman strength, speed, and durability, and is not afraid to use her powers to protect those she cares for.
- Armor-Piercing Response: When Endo bullies Jon and talks smack about Hyperion, Maigo shuts him up by pulling rank as Nemesis's first Voice and making it clear that her being Hyperion's Voice is the only reason Nemesis is still alive.
- Bash Brothers: She and Lilly make an effective team, both of them possessing superhuman combat abilities. They also consider each other sisters in all-but blood, and frequently hang out together outside of missions.

- The Conscience: She tried her hardest to temper Nemesis' Black and White Insanity with compassion and empathy.
- Deadpan Snarker: She picks up on Jon's wry sense of humor. For example, in Project 731 when Woodstock wonders why Nemesis hadn't eaten them over the course of the first two books, Maigo mutters that she thought he wouldn't taste good.
- Fighting from the Inside: Throughout the first book she struggles against Nemesis' bloodlust, and despairs when she fails to stop herself from eating people.
- Genetic Memory: Presumably how she possesses the original Maigo's memories, as well as those of Nemesis Prime. She retains a psychic connection to Nemesis that is only severed when Endo takes her place as the Kaiju's Voice.
- Half-Human Hybrid: Despite being physically human she retains superhuman strength, speed, and durability surpassing even that of Lilly.
- Heroic Host: She tried to temper Nemesis's rage with empathy to the point where when she was expelled Nemesis felt incomplete without her. In Project 731, she attempts to return to Nemesis and function as this again, but Endo takes her place instead.
- Im A Monster: While she's a little smug about her powers, the fact that she was once a part of Nemesis and remains mentally connected to her causes her a significant amount of grief. Specifically, she's terrified that she'll undergo a metamorphosis like General Gordon did.
- Literal Split Personality: She originally existed as a voice in Nemesis' head, until she was given a body of her own.
- Lovely Angels: In the epilogue of Project 731 and the early part of Project Hyperion, Maigo and Lilly team up due to both of them possessing superhuman abilities.
- Necessary Evil: Maigo is livid that Jon would readily agree to kill Nemesis, arguing that her former self is capable of defending mankind from threats nothing else can, even if it means sacrificing those caught in the crossfire.
- Plot-Relevant Age-Up: Her original self died at the age of 13. Nemesis metamorphosed into a monster at approximately the age of 18, and Maigo 2.0 is physically 16 when she's expelled.
- Pro-Human Transhuman: Despite retaining superhuman abilities as a result of having once been a part of Nemesis, she fights on the side of the humans.
- Psychic Link: She possesses one with Jon due to his actions at the end of Project Nemesis, and well as with Nemesis. The latter is mostly severed by Endo becoming Nemesis's Voice.
- Sharing a Body: Maigo's relationship with Nemesis up to the end of Project Maigo, where she is reborn as a human.
- Supernatural Angst: She's physically 16 in Project 731, with all the teenage issues that go with that, but not only does she have to deal with puberty but the memories of having been a 350 foot-tall revenge-obsessed monster with a taste for human flesh.
- Vague Age: Hudson's best guess regarding her physical age when she separated from Nemesis is 16, though he admits that's only an estimate, and several years pass between then and the end of the series.
- Woobie, Destroyer of Worlds: Her rage over her past self's murder occasionally synchronizes with Nemesis' bloodlust, and when it does, look out.
- Anti-Villain: He's an assassin, but not completely remorseless. That said, he suppresses whatever remorse he feels to get the job done.

- Chronic Backstabbing Disorder: He's willing to betray anyone in order to facilitate his goals.
- Corrupt Corporate Executive: Alessi reveals that Katsu became the chief shareholder of a company. Said company was Zoomb, which he used definitely illicit means to seize control of. However, he's a rare benevolent example, since he makes Jon his successor before merging with Nemesis.
- Friendly Enemy: To Jon, and to a lesser extent the other DHS-P personnel. He doesn't think of them as enemies per sae and genuinely respects them.
- HeelFace Revolving Door: Kendo works alongside both the villains and heroes to achieve his goals, changing sides like shirts. Ultimately, he proves a force for good.
- Hidden Agenda Villain: He keeps his true loyalties secret from everyone, though Jon eventually figures him out.
- Professional Killer: In the first book, he works for General Gordon. In the second book he works for Zoomb. In the third book, he works as a double-agent for GOD. His job: disposing of people.

- Cloning Blues: He has a number of clones.

- Beware My Stinger Tail: Her tail is tipped with a trident-shaped spike which she uses to stab and/or slash her opponents.
- Black and White Insanity: She has Nemesis Prime's torture-induced instinct to punish all injustice, no matter how minor. Those who get in her way are expendable.
- Bloody Murder: The glowing orange blood-like fluid contained in the membranes explodes with the force of a small nuke when it reacts to oxygen.
- Breath Weapon: She can vomit globules of the explosive orange fluid, an ability Hudson dubs "Scorching Contempt".
- Clipped-Wing Angel: Nemesis's "Stage 4" form has wings that she can use to refract and focus sunlight into a deadly weapon, but in order to do so she has to shed her "Stage 3" form's exoskeleton and becomes vulnerable to attacks.
- Dark Action Girl: She is a female kaiju driven to punish those she deems guilty, no matter how minor the crime.
- Dark Is Not Evil: If anything, she's the lesser evil of the dangers she faces.

- Pay Evil unto Evil: She is driven to kill those who she deems guilty. Those who get in the way are collateral damage.
- Puny Earthlings: Nemesis initially takes a very contemptuous view of humanity, considering them to be prey at best. Maigo's influence softens this outlook such that Nemesis begins attempting to avoid collateral damage in her fights.
- Roaring Rampage of Revenge: Nemesis horrifically kills thousands of people - innocent and otherwise - to avenge Maigo's death.

- Took a Level in Jerkass: Yes, Nemesis ate a lot of people in the first book, some of whom deserved it and most of whom didn't, but she tried to make quick kills. In the second book she's neccesary to stop the other monsters and typically disabled them with a purpose before finishing them. Without Maigo to temper her rage and bloodlust in the third book, Nemesis is suddenly a lot crueler and drags out kills.
- Was Once a Man: She started out as a clone of Maigo Tilly, which was spliced with the genetic material of an alien monster as an embryo.
- What Is This Feeling?: Initially Nemesis is defined solely by instinctual rage and bloodlust, but over time Maigo's consciousness begins asserting itself in the form of emotions like love, compassion, and kindness. Nemesis is initially confused and disgusted by such weak emotions, but by the end of the first book comes to accept Maigo's presence within her.

- Lamprey Mouth: It has a round mouth ringed with teeth.
- Shout-Out: Hudson names it after the cosmic horror author Howard Phillips Lovecraft, positing that the Ferox collaborated with its namesake's writings in an attempt to install a fear of anything with tentacles for a face in mankind.

- Metamorphosis: Like Nemesis Prime and her offering, it can shed its exoskeleton to assume a smaller, sleeker, but no less deadly form.
- Lightning Bruiser: With its thin build and sharp tail it can run circles around enemies before cutting them up.
- Shout-Out: Lilly named it as one to Hans Rudolf Giger, the artist who designed the Xenomorphs.
- Xenomorph Xerox: It bears a strong outward resemblance to the Xenomorphs from Alien, hence its name.
- Absurdly Youthful Mother: Upon reaching physical maturity she laid a trio of eggs that hatched into cat-like creatures.

- Bash Brothers: She and Maigo make an effective team, both of them possessing superhuman combat abilities. They also consider each other sisters in all-but blood, and frequently hang out together outside of missions.
- Blood Knight: She was bred to instinctively delight in combat, something she tries to suppress.
- Can't Have Sex, Ever: She angsts to Joliet that since she reproduces asexually there's no point in getting laid, and the only people who would be interested in her anyways would be "a total freak. Probably one of those Furry pervs".

- Fragile Speedster: She's lightning-fast and super-strong, but she lacks the durability of General Gordon.
- Happily Adopted: She was adopted by Mark Hawkins and Avril Joliet. She later comes to consider Jon and Ashley to be her uncle and aunt, and treats Maigo's clone like a little sister.
- Incompatible Orientation: In Project 731, when trying to convey an important message about Nemesis needing a Voice to fight effectively to the others while doped up on painkillers, she giddily quips that she "doesn't swing that way" — Nemesis having tried to choose her.
- Intoxication Ensues: In the third book, she's put on enough pain medication to make her act high out of her mind, interfering with her ability to convey an important message regarding Nemesis.
- Lady Looks Like a Dude: Justified due to her looking like a five year-old child at a time, with her fur covering her naughty parts, but Mark thought she was a boy when she first met.
- Mama Bear: She initially tried to kill Hudson and Collins, thinking they were going to hurt her children.
- Mix-and-Match Critters: She looks like a Cat Girl, but she also has webbed toes, a prehensile tail, gills, and a telescopic tongue.

- Smug Super: The fact that she's faster and stronger than everyone else on the team causes her to become arrogant when she routinely beats everyone at capture the flag. Even as a child she was confident in the inherit superiority of chimera over humans.

- Super Not-Drowning Skills: She has gills enabling her to breathe underwater, and webbing between her toes that makes her an effective swimmer.

- Younger Than They Look: She's roughly six, but appears to be in her late teens or early twenties.
- Brainwashed and Crazy: She was conditioned to instinctively obey Bennett's commands.

- Humongous Mecha: It's an alien war machine roughly the same height as Nemesis.
- Mechanical Lifeforms: It is at least partially biomechanical in nature, as its body is made up of self-repairing metallic cells.
- Robot Buddy: It's given a mind of its own in Project: Legion allowing it to act independently of Maigo.
- Shock and Awe: When it's ⅔ charged, it can swap its arm-blades out for electrified prongs.
- Wave Motion Gun: Once fully charged, its head and arms can change into weapons that have enough firepower to blow a hole through Nemesis Prime's entire body.
- Weaponized Teleportation: It can teleport anywhere when at full power.
