These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Broken Base: Albeit not as bad as its sister show, the older fans that are outside of the target demographic have made numerous complaints about how the 2nd season wasn't as serious as the 1st. The younger fans within the demographic, on the other hand, are completely fine with the show's current state.
Van Kleiss is the ruthless dictator of Abysus who uses propaganda to claim he's trying to build a better world for EVOs, while in actuality Van Kleiss cares only for his dream of world domination, and nothing for his subordinates. Van Kleiss makes a habit of petrifying EVOs by sucking the nanites out of them, or turning regular people into EVOs to act as muscle for him, not caring that such an action could leave them permanently transformed. In his bid for power Van Kleiss murdered Rex's parents, experimented on his Woobie, Destroyer of Worlds follower to amplify her powers while causing her excruciating pain, and threatened a little girl to force her father to turn the people of New York into his zombie army.
Branden Moses announced a breakthrough in nanite research that allowed him to dramatically reverse E.V.O. mutations and gave a faux demonstration using an E.V.O. and either an actress with a set of prosthetic tentacles or an E.V.O. with tentacles, playing the part of the "cured E.V.O." Having convinced hundreds, possibly thousands, of people (including Dr. Holiday, who added her sister Beverly Holiday to Brandon's ranks) that he had made a breakthrough, dozens of intelligent but physically deformed, incurable E.V.O.s lined up to be cured. Instead, they were kidnapped and brought to a lab in the Arctic circle where their mutations were amplified and were ready to be auctioned off to the warlord with the deepest pockets.
There also seems to be a good amount towards Rex/Breach.
Foe Yay: Gatlocke and Rex. Every other sentence in Gatlocke's fight with Rex was something like "Oh, I like that!" or "I've got a serious case of Evo-envy!"
Growing the Beard: Many feel that the show has been getting better since the second half of season 1 started.
Harsher in Hindsight: At the end of "A Family Holiday," after Six nearly dies, he and Rex have a Heartwarming Moment in which Rex tells him, rather affectionately, never to do anything like that again. Seems like a throwaway line until "Six Minus Six," when we see what happens the next time Six jams his magnetized blades into a machine.
This pops up every time Van Kleiss apparently dies, due to obvious reasons, but the best example is Breach. When you apparently kill off the Ensemble Darkhorse, you better believe this'll happen! Note that while Dr. Holiday is skeptical that she's dead, Van Kleiss seems to have moved on and is looking for a replacement.
Some may be hoping that Rylander is still out there.
He is...though he's currently a deformed subject in a lab tank.
Characters increasingly get critical and distrustful of Providence despite the fact that EVOs present a clear danger to the entire world, Providence has two EVOs working for them (one with a criminal record), and Cure, contain, or kill really does seem like the only viable approach to problem EVOs. Not to mention we never see Providence so much as threaten to cure, contain, or kill a human EVO that isn't threatening others.
It's mainly due to White Knight's Jerkass tendencies.
Jerkass Woobie: Breach gets this status in her title episode. Sure, she's an evil, possessive kidnapper, but when her pocket dimension is being trashed by Rex and the Creepy Girl, they're essentially tearing her mind apart. Regardless of the situation, you had to feel sorry for Breach there.
Magnificent Bitch: Black Knight, full stop. From posing as a Reasonable Authority Figure, keeping her own true power hidden to use at later date when necessary, playing politics with the Consortium, and pulling off a success starscream to gain supreme power, she's fit the bill big time.
Memetic Molester: Van Kleiss is very creepy when he tells Rex how "special" he is or how much he needs him.
Moral Event Horizon: Providence under Black Knight crosses it in "Back in Black" when they employ Mind Control technology to deal with EVOs, even sapient ones.Cesar Salazar definitely crosses it when he tries to use this technology on Rex, his own younger brother.
Van Kleiss' treatment of Breach is definately this for him.
Nightmare Retardant: The series is pretty on-and-off on how seriously it treats its premise (which honestly sounds like something from a post-apocalyptic horror movie), but it definitely butts heads when the hero is fighting Lovecraftian horrors to a rock theme and stock sound effects.
In the show's universe, they're everywhere, in everyone, and at any second you or someone you know could end up an EVO. Pleasant dreams!
Things go From Bad to Worse: The nanites infested every living thing. Meaning anything from algae colonies on up to trees and animals (this actually happens!) could turn into an Eldritch Abomination out to waste you. Suddenly your backyard looks a little more worrying...
Or if the symbiotic bacteria that live in someone's gut suddenly went EVO without the person going EVO... considering how EVOs tend to get big and go on destructive rampages... *shudder*
Eggs are a reproductive cell, so there's the horror of the implication of reproductive cells going EVO. But then this is taken a step further. It's common practice for some egg farms to incubate all their eggs for 3 days after Laying, those that show any kind of development get sent to hatcheries, those that don't get sent to market. it's not uncommon for a developing egg to slip into the market batch (it's not unheard of to find half developed chicks in grocery store eggs). So think of the implications if this practice is still in play in the Generator Rex universe. Those eggs seen in "Moonlighting" could have been EMBRYOS. Think of a world where embryos could go EVO at anypoint in their development.
Then consider the implications of a pregnant mother going EVO. What happens to the fetus?
What happens when the fetus goes EVO and the mother doesn't?
Despite Circe and the rest of the Hong Kong gang denying it, they do seem to get awfully close to each other WHILE they're proclaiming themselves as 'just friends.' It helped that the boys decided to make their move after it, though.
Certainly intentional, as the Running Gag in that episode was basically them confusing the hell out of Rex.
Then Played Straight, because in that episode, Circe was trying to get over her troubled past life, changing her appearance, and flirting with Sqywid, when Rex brought up their past, she got a little upset, and by the end of the episode, it appears She and Sqwwid are going to become an item, and she seems to end her relationship with Rex. In later episodes her appearance is back to normal, and she still likes Rex, her relationship to Squwid is never brought up, outside of a throwaway line where he tells her to escape and leave them.
Some find Bobo difficult to tolerate because he's more a liability than a help usually and he does a lot of questionable things that he is never reined in for by Providence. Plus a talking, smartmouthed monkey seems a bit out of place at times when the show is dealing with some pretty serious and disturbing things.
Rex's nanite overload and the nanite monster in "Frostbite".
A bit of unintentional squick, that hopefully the creators did by accident. ZAG-RS is programmed with the voice of Rex's late mother. He also has the hots for Doctor Holiday. Both are voiced by Grey DeLisle. So, when you think about it Rex has the hots for a chick who sounds exactly like his mother.
In Heroes United, Ben uses Upgrade to merge with Rex, becoming a full-body suit inside and out. One hopes his tactile sensation as Upgrade is rather low.
They Wasted a Perfectly Good Plot: "Operation: Wingman": Who else thought that Annie was the EVO-Bunny, and all of her "accidents" during the date were genuine attempts to kill Rex? Jossed since it was stated that she's like that with every date, but still...
Rex's two giant robot builds. The first form is obscured in shadows, and is only alluded to about twice in the series outside of flashbacks. He never uses it. It would have been nice to have a few episodes showing Rex being forced to use it in a desperate situation, and fully considering the ramifications of it, rather than seemingly rushing it in the final episode. His second giant build seems to be less a full use of all builds than a generic giant robot, which doesn't use any of his Omega-Nanite builds.
Of course, we also have things like Providence (the name suggesting divine intervention, if not outright God) and an infection of Nanites that is in everyone and everything (much like sin, in the orthodox Christian sense).
The Woobie: Holiday after we find out what happened to her sister, especially in "A Family Holiday."
"Lions and Lambs" turns Breach (formerly a Jerkass Woobie) into a full-on Woobie. Oh so very much.
