- Creator's Pet: With Drew Luczynski's admittance to her and Drew being amongst his favorite characters, plus Nathanoraptor's own thoughts about her, there was initially the possibility that Cynthia could end up becoming this. However, thanks to several subsequent developments she's undergone, her and Drew becoming an official couple, not to mention the heavily hinted possibility that she might be a mole, and later confirmation as a reverse mole, she appears so far to have largely shaken off this possibility.
- Ensemble Dark Horse: Nathanoraptor has admitted that he himself ended up liking Leon and Yolanda much more than he initially expected over the course of writing their dialogue in "The First Steps."
- Hilarious in Hindsight:
- Scarlett Johansson portraying Linda Eberhart (at least that's how Nathanoraptor believes it could work). This certainly wouldn't be the first time she's played a somewhat kindly character who works at a zoo.
- Turns out, Black Widow, Heimdall, and Spiderman have ended up working together at the exact same establishment; which is owned by the fake Mandarin, to boot!
- To continue the MCU related hilarity, ABOMBINATION is the head of security!
- And on yet more Marvel-related (though not necessarily MCU) hilarity, Will Simpson is the head of the park's research department and Cannonball is the leader of the rescue team!
- And for that matter, we also have Kaa and Shere Khan working on the same team once more.
- Jerkass Woobie: Leon and Jack somewhat qualify depending on point of view. Jack qualifies in that he's a confirmed Stepford Smiler and secretly feels very lonely and friendless. Leon also qualifies in that he was bullied in school before ever making any friends, and can somewhat hold sympathetic value in autistic readers who may or may not know how he feels and understand him. While they both are very jerkassy to each other in Life in Transition, it is not hard to feel sorry for either of them or side with one or the other.
- Pandering to the Base: The viewpoint some might have over the inclusion of Will and Matt at the moment they made their first appearance. Drew Luczynski didn't want them to be included at that particular point in the story, but Nathanoraptor convinced him into putting them in at the cost of developing Cynthia due partially to reader demand and partially to their importance to Alice's character.
- The Scrappy: Cynthia, when she was first introduced, was not liked by the readers, with many citing her lack of substance compared to the other characters and her being immediately shoved into a prominent role as failings. Even Nathanoraptor has stated he did not like the character. However, in Phase Three, she largely got Rescued from the Scrappy Heap.
- Strangled by the Red String: In a sense, Collete and Jack. While the relationship is admittedly teased more than once prior to hooking up and shown to be quite compatible in its own way through what development ''is'' shown, a relative lack of focus on their relationship's development (and that of Collete herself as a character) between the first moment of Ship Tease between them and the moment they hook up can give off a rushed feeling.
- Unexpected Character: As Liliensternus has only previous appeared in Walking With Dinosaurs: The Arena Spectacular, the appearance of a pair in Degrees Of Greatness definitely counts as this.
- They Wasted a Perfectly Good Character:
- Will and Matt. First introduced in The New Rulers and teased by Nathanoraptor to have major importance to Alice's character arc later in the story. So far though, they have made only a select few appearances, made scarcely any impact on the plot since introduction, and have yet to reach the point where they showcase the promised importance, until Phase 3 that is.
- Khatin has had very little (if any) major appearances or moments in the story since he first helped Squishy overcome his initial loneliness at the park.
- In a way, Adrian. He is best friends with Leon and Drew, but has since become very out of focus and later ends up very abruptly going full Chuck Cunningham immediately after his one single appearance in A Glorious Dawn in favor of Jack unofficially taking his place. That being said though, Nathanoraptor has since stated that several developments that unfolded while the story itself, plus several chapters that were later being written for release, were in development caused them to give Jack the more prominent role initially considered for Adrian on account of just how much more interesting Jack ended up becoming to the authors.
- They Wasted a Perfectly Good Plot: Adrian and the Denhams are able to escape from the fire during their time in the Jurassic Period remarkably quickly; almost anticlimactically. Then again, considering how the swamp fire in "Alien Empire" was already plenty drawn out and epic, this comparatively more swiftly open and shut case may not necessarily be a bad thing.
