* ClicheStorm: A humble farm-boy discovers upon reaching manhood, that he is [[LastOfHisKind the last of his line]], related to a villain by blood, is destined to take the throne, quickly becomes a total badass, inspires people to rebel against a corrupt king, even ends up winning the heart of a princess he rescues... fortunately that's just the first couple books. [[RealityEnsues Book 2 begins with him being given all sorts of crash courses in history given that he never grew up educated and learning actual fighting techniques, and people getting in trouble when he goes out recklessly]].
* CompleteMonster:
** [[TheEvilPrince Prince Lucas]] the werelion is Drew's [[CainAndAbel half-brother]] and everything Drew is not. Always a SpoiledBrat and an apprentice {{Necromancer}}, he began to [[SanitySlippage lose his sanity]] after he murdered Lord Broghan in front of his cousin, and former fiancée, Lady Gretchen under Opal's instructions. He goes downhill the moment he murders his [[{{Patricide}} father]] Leopold under the other Catlords' orders. His interest in BlackMagic leads him to work with the Wylderman Darkheart to create the [[AnimalisticAbomination Wyld]] [[SavageWolves Wolves]], who slaughter the Sturmlands' army, an act that [[EvenEvilHasStandards disgusts the other Werelords]]. He then murders Duke Henrik to "[[UnwantedRescue save]]" [[BloodKnight Lord Onyx]] after he [[HonorBeforeReason honorably accepted]] his defeat at his CombatByChampion. When he finds out that Gretchen's in the Dalelands he leads his Wyld Wolves in a [[RapePillageAndBurn bloody campaign]] to get her, killing several innocents in the process. He undoubtedly crosses the MoralEventHorizon by [[WouldHurtAChild killing Lord Milo]] in [[YouSaidYouWouldLetThemGo front]] of Trent, partially [[ImAHumanitarian eating]] him. When his grandfather Leon punishes him for killing his father and tries to get him to regain some honor, he murders his grandfather as well. When he arrives to Icegarden to kill Hector for [[YouKilledMyFather killing his mother]], [[SplitPersonalityTakeover Vincent of Redmire]] retorts that he's only here settle a [[EvilIsPetty petty grudge]] towards Hector for always being smarter than him. Vicious and [[AxCrazy insane]], throughout the books he devolved from a simple RoyalBrat, to a cannibalistic SerialKiller.
** The aforementioned Vincent the wereboar, initially the scheming twin brother of Baron Hector who inadvertently causes his father's death and ends up dead in an attempt to murder Hector for the throne of the Dalelands, ends up becoming far more evil than even his brother could have predicted upon becoming a [[OurGhostsAreDifferent vile]]. Haunting Hector and [[DrivenToMadness driving him to gradual madness]], Hector [[TheCorrupter turns his once-noble brother into a murderer and a torturer of innocents]], eagerly convincing him to slaughter his former allies and all the witnesses to this—including, in one case, a harmless [[WouldHurtAChild cabin boy]]-- ultimately precipitating Hector's betrayal of the Wolf's Council and sell-out of the Dalelands to the evil Prince Lucas. Upon devouring the spirit of Hector's old mentor and seizing Icegarden, Vincent becomes far more proactive in his brother's schemes, eagerly [[ColdBloodedTorture torturing]] Duchess Freya for weeks on end in order to wrestle the Wyrmstaff out of her and accidentally influencing his murder of Queen Amelie, of which Vincent cruelly taunts Hector about. Eventually, tired of his brother's unused potential, Vincent overtakes and [[DemonicPossession fully possesses]] Hector himself, keeping his brother's mind aware and helpless as he slaughters and resurrects even his own allies, keeping their souls tortuously bound to their dead bodies for his own advantage. Rechristened Lord Blackhand, Vincent starts [[{{Necromancer}} resurrecting the dead]] by the thousands to slaughter all in their wake, decorating Icegarden's walls with the bodies of those he's slaughtered and driving his legions in a crusade to destroy whatever cannot be dominated. Vincent goes from a smug, would-be warlord to a corrupter, a literal monster, and an eventual tyrant who becomes a greater threat than even than Prince Lucas himself, and eventually dies as one of the greatest threats to have ever scourged the Seven Realms.
** [[SnakesAreSinister Vala the wereserpent]], from the first two books and the fourth book, is the [[AGodAmI self-proclaimed goddess]] of the cannibalistic Wyldermen, who [[ImAHumanitarian offer]] her human and werecreature alike. Defeated by [[TheHero Drew]], she plotted her revenge against him and those he cares about. First she [[DeadPersonImpersonation killed and impersonated]] the [[EvilOldFolks crone Baba Korga]], pretending to be an ally of Whitley and using her to enter Five Oaks unnoticed. During her "[[FauxAffablyEvil friendly talk]]" with Whitley, she revealed her biggest atrocity: during the journey she [[EatsBabies devoured]] innocent Romari [[WouldHurtAChild children]] when no one was watching. She then explains her intentions of turning the Dyrewood into her realm, where she and the Wyldermen can kill and eat with impunity. She also mentioned her plan of using Whitley as bait to attract Drew, and in an act of "[[CruelMercy mercy]]", she promises to kill Whitley quickly after she had dispatched Drew. [[{{Pride}} Prideful]], [[EvilIsPetty petty]], and convinced that she had the right to kill and devour whenever she wanted, she [[FantasticRacism saw humans as nothing but food and other Therianthropes as weaklings]].
** [[ThreateningShark Deadeye the wereshark]], the captain of the ''Hellhound'' in the employ of Lord Ghul in the 5th book ''Storm of Sharks'', makes a name for himself on the White Sea as a practitioner of brutal violence and rampant [[ImAHumanitarian cannibalism]]. Attacking the smuggler ship ''Lucky Shot'' upon learning of the presence of werelords on it, Deadeye slaughters many of the crew himself and eats its captain alive before taking those who remain as his prisoners and slaves. Holding a [[StalkerWithACrush special affinity]] for the werelord Whitley, Deadeye subjects Whitley to his perverted attentions whilst keeping her collared, informing Whitley's intention to make her his bride in between subtle hints of violence. Upon being attacked by the ''Maelstrom'', Deadeye snaps and starts massacring both enemy soldiers and [[BadBoss his own men]], brutally tearing apart Captain Ransome's young friend Hob shortly before his own death.
* CosmicDeadline: The ending can feel rather sudden, with just about all the greater threats being dispatched at the end, and only two chapters after the climax really gives a resolution, complete with [[spoiler: Trent's infection being cured entirely offscreen]].
* MoralEventHorizon: [[spoiler:Hector either crosses it when he tries to kill Vega, or when he changes his mind about sparing 9 year old Pick]].
** While Lucas is no stranger to this (and likely crossed it within book one), in-universe, he seems to cross it when he [[spoiler: mauls Milo to death]].
* TheyWastedAPerfectlyGoodCharacter: The other lions - Leopold's father, during his brief screentime, shows that he is as passionate as all the other Catlords, but has far more reason within him than his son and grandson. Sadly, [[spoiler: Lucas kills him]], and we do not get to know of things from their point of view.
