Complete Monster: Haggarty is a lone survivor of the plague who showed up at a dam where the self-sustaining community Project Evergreen was located. At first seeming kind and helpful, he waited until a large group left to scavenge and killed almost everyone who stayed behind. After killing the community's leader, he took the man's wife and daughter for his own and locked everyone else out to fend for themselves. When Jeppard's group arrives at the dam, Haggarty had taken on the identity of the friendly, handicapped Walter Fish. He convinces them that the remaining members of Project Evergreen are violent scavengers, leading to Jeppard's group killing some of them. When most of the men leave, Haggarty ties up everyone but the teenager Becky, telling her that whenever she disobeys him, he'll kill one of her friends. When the others manage to escape, Haggarty tries to kill them all.
The Show:
Base-Breaking Character: Some viewers hate Gus for being Too Dumb to Live. However, other viewers believe him being a sheltered child who was kept away from the world until being forced to leave his home justifies his poor choices as he adapts to a new environment.
Ensemble Dark Horse: Johnny has become a popular character for being nice to Adithya and Rani, and for being the Token Good Teammate of the Last Men (which he was in the comic).
Fridge Horror: So many different hybrids species. But how did their mothers give birth to them? Some hybrids are animals that would not be easy on the human body to give birth to; such as an elephant, turtle, and even a porcupine. The last one already has their quills as a newborn, so their birth might've been the most painful one out of all... unless, like regular porcupines, the baby's quills were soft at birth.
He Really Can Act: Adeel Akhtar as Adithya, who manages to give a sympathetic performance as one of the only people with morals in his community.
Narm: Nancie's death is meant to be portrayed in a serious light, but the way she went out (Adithya's horse, Trixie, kicking her) and how it's executed has resulted in one of the most unintentionally hilarious scenes in the show.
There was no way that Adithya and Rani were going up in flames in Episode 5. The show was building them up to be major characters and they hadn't even interacted with other major characters yet.
Jepperd surviving the gunshot wound at the end of the first season was a given.
Despite a lot of people dying in the Season 2 finale, obviously Gus had to survive getting shot in the back.
What Adithya and Rani's community does to those infected with the Sick is pretty horrifying. After they found out that Doug had the Sick, they refrain and bind him up to a chair in cellophane wrap and subsequently burn his house down with him inside it. It's unsettling as we hear the poor guy beg for his life as they simply ignore him and leave him to burn. They later attempt to do the same to Adithya and Rani as well after finding out that she was Sick, but they were "saved" by the Last Men. You don't want them to suspect you of being Sick, as one man was found out by not attending a community party and they responded by also burning his house down.
The Last Men in general. They have no qualms about hurting hybrids for sport and experimentation - them being children is irrelevant. Gus is nearly maimed by them in the first episode and would have brutally died if Jepperd hadn't shown up.
Ron the Death Eater: Many viewers see Adithya as incredibly selfish for prioritizing his wife over the life of hybrid children, with his dissection of a chameleon hybrid child being seen as a Moral Event Horizon. However, it's clear that Adithya is not happy about this - he more or less says that hybrid experimentation goes against everything he believes in, and earlier in the season, turns down Dr. Bells request to continue her work for that very reason. Besides, in the aforementioned scene, his captor (who's forcing him to find the cure by using his wife as leverage) is watching.
Wendy has a pig nose, ears, and is implied to have a tail. Despite these animal traits, she otherwise looks like a little girl.
Bobby is a ground-hog hybrid who can walk (albeit clumsily), is marginally bigger than an actual groundhog, the smallest hybrid, and has human eyes. Yet, fans easily overlooks those traits with his heart-melting moments and he has since become a fan-favorite character.
The Scrappy: Rani isn't well-liked by viewers. She convinces Aditya to experiment on the hybrids, stating her life is worth more than countless children(though she later changes her mind when she realizes the hybrids are actually intelligent). The fact that her sole existence is to make Aditya's Reluctant Mad Scientist situation more sympathetic doesn't make it any better.
Gus is born in a world that fears him and wants him dead for being a hybrid. When he is 10, his primary caretaker dies, leaving him alone for about a year. Then he finds out that he was a science experiment, leading to a Heroic BSoD.
Bear is an orphan whose hybrid sister was taken away from her by the government shortly after her loving foster parents died from the Sick. She was just a little girl herself and is seen giving a Howl of Sorrow as her life fell apart in a single day. While she eventually finds a new home as the leader of the Animal Army, they eventually turn against her when she refuses to execute Jepperd.
