It's Personal: Meander's father was wild. Rule and Polarizing are exploiting wild coyotes. You do the mathematics.
Loss of Identity: When Meander's halo brain is destroyed by Rule, the construct that was Meander dies, even if his body and its base animal instincts survive him. The court case that follows factors this heavily.
Meaningful Name: "It means to worm around kind of leisurely." Turns out Meander chose that because his mind is constantly wandering.
Jerk with a Heart of Gold: Sure, she isn't the nicest animal around, what with beating up and yelling at other people more than once. However, when it counts, she's willing to stick up for her loved ones. Yes, even those accused of murder.
Meaningful Name: Subverted! "Quintet" refers to the "main cat" and the cats created by her metanoia... but in fact, those cats are four different reflections of herself. So she's actually a "Quartet".
Meander's teacher. Works with Polarizing to exploit "wild" animals for things like slave labor and meat, an extreme taboo in their society.
Hero of Another Story: On page 183, Fiat mentions that she was born with dextrocardia. When asked about why she mentioned this detail, Braun said that it's actually important to her own story (if it ever does get told). And by story, he means, well... this:
Fiat's story would be a full-blown NofNA storyline, since it would have its own plot. She just happened to be enough of a character to have a foot in this story.
One of the many children of the crime lord Keratin. He (alongside a long tract of land) was sold to Rule and Polarizing in exchange for wild coyote slaves. A major source of comic relief for much of this arc's conflict.
Abusive Parents: His father has so many kids, he didn't think twice about offering one in exchange for valuable servants.
Break the Cutie: the pile of coyote pup corpses and the death of Rule will likely haunt his dreams forever.
Chekhov's Gunman: Ultimately subverted. His testimony doesn't swing the ruling in the case of Rule's murder one way or another.
Head Pet: Technically, Keratin did sell him to Rule....
The Mafia: His father is more or less a bunny don.
Royal Brat: he constantly refers to Meander and the coyotes as "bugs", due in part to the way he was raised. his father asks him not to say anything to Rule's detriment, but it's clear he'd no intention of doing so, anyway.
SV / Marigold / Malice (Degu)
The protagonist of Secretary. An ambitious and impatient student out to prove he has something of worth to add to the world.
The protagonist of Lycosa. At the start of the arc, she's searching for her lost eggsack. When she finds out that Venom 8 have taken it, she goes on a Roaring Rampage of Revenge. And that's the basic plot of the arc... but it wouldn't be NofNA without a twist at the end, now would it?
One Spider Army: She takes on the entire Pisaurina clan by herself. And wins.
Talking to Themself: What we're initially led to believe Gulosa is doing at one point, albeit with her unusually argumentative inner doubts instead of another personality. The reality of the situation is quite different....
The antagonists of Lycosa. The Venom 8 team is a group of eight (actually nine) spiders who aim to create a spider equivalent to the internet that all spiders are always connected to. This requires egg sacs from every spider species, which kicks off the arc. One by one, we meet them, and one by one, Lycosa kills them off.The members of Venom 8 are, in order of appearance: Deinopis spinosa, Antrodiaetus unicolor, Argiope aurantia, Scytodes thoracica, Mastophora cornigera, Patu digua, Theraphosa blondi, and Nephila clavipes... with the ninth being Gladicosa gulosa.
The Beastmaster: two of their number are adept at controlling praying mantises and hornets, respectively.
Dark Action Girl: All of them except for the ninth, Gladicosa gulosa. They are spiders, after all.
Giant Spider: Theraphosa blondi. That species is called the Goliath Birdeater for a reason.
Abusive Parents: It's implied that Hector's birth father was one of these. Removing your son's tail because he "didn't deserve a 'tale'" is harsh.
Amazing Technicolour Wildlife: Strelka - ever seen a green border collie before? (Even her nose is green!) Given that this arc is set so far into the future, it's possible that genetic engineering had a hand in this.
Ambiguously Brown: Deliberately in the case of Yuri; Word of God has stated that he's supposed to look a little bit like every race. That said, judging by the name, he's probably Russian (or of Russian descent).
Ambiguously Human: Evander and Diana have pointy ears, but otherwise appear completely human.
