Raptus' sudden HeelFace Turn during the Season 2 finale is rather sudden that it brings to question; was Raptus always evil, or did his constant defeats at the hands of Off-World entities fuel a rash decision?
Striker's willingness to kill Raptus. Black and White morality, or belief that Raptus was too far gone and had to be put down before others could be harmed?
Ass Pull - Some viewers saw Raptus' sudden FaceHeel Turn a random and poorly added device meant to simply further the plot.
Broken Base - Raptus' betrayal and overall fate. Some viewers felt his unprecedented turn to villainy was an excellent plot point to further Striker's story, and that Raptus deserved to die for his actions in stealing the power nodes of Stikbot prisoners. Other viewers felt that Raptus' betrayal was horribly executed, with it being too sudden and having very little context or decent motivation, with Raptus' later actions opposing his prior character traits; additionally, Striker's quick willingness to kill his war comrade has caused conflict, as it clashes with his ideals of helping others. Most viewers have practically forgotten Raptus by now, while only a few viewers hope the character will make a return in future seasons.
Season 1, Episode 1 - the series begins with Stikbot citizens gathering over the disappearances of other Stikbots within the GRID, when suddenly one pink Stikbot starts screaming "WE'RE ALL GONNA DIE!" before being knocked out by Striker. Shortly after Striker calms the citizens and everyone leaves, the pink Stikbot just as suddenly regains consciousness and resumes screaming "WE'RE ALL GONNA DIE!" before realizing everyone's gone.
Season 1, Episode 7 - one of the Stikbot prisoners attempts to escape his captors by playing dead, only for the Predator to unsheathe its blade, prompting the Stikbot to quickly recover.
Season 1, Episode 12 - Striker has finished going through a Lock and Load montage in preparation to play Cecilia's game, thinking they will be fighting to the death. Cecila surprises him by revealing that they WON'T be fighting to the death, pointing out that Striker can't harm her in any way, thus rendering a fight pointless.
Ask Your Questions! - When Striker proposes that viewers ask the heroes (i.e. Raptus, Pixel, Shift), cheers are heard. When Striker proposes that viewers ask the villains (i.e. Vamprah, Regalius, Cecilia), a fake scream effect is heard.
Q&A with the Cast - reading a comment regarding whether Raptus and Shift will come back for Season 2 prompts the two to point out that answering said comment would be a huge spoiler.
Pixel and Striker begin talking about the process of becoming "Spark Mates", causing Shift to exclaim disgust, claiming the content to be "lovey dovey", with Striker accusing Shift of being jealous due to not having a Spark Mate. Shift then asks Raptus is he has a spark mate, to which Raptus responds in his most deadpan voice, "My spark mate is dead". Cue silence and cricket chirps.
Hearing Striker say he'd want the power to shoot lasers and Raptus complain that nobody's asked him what powers he'd want is humorous to hear.
Season 2, Episode 1 - Striker's interactions with Off-Grid individuals gives off an awkwardness due to their difference in size, along with Striker's over-friendliness in comparison to the individual's cold cynicism.
Highlord Vamprah's introduction has her brutally dismember a rebellious Stikbot prisoner in a Kylo Ren fashion.
The reveal that all Stikbots that are captured have their life force practically sucked out of them through a very excruciatingly painful electrocution until only a hollow, soulless shell is left behind.
Season 2, Episode 5 begins with a flashback to the Great Stikbot War in an infirmary full of wounded Stikbots, with Striker tending to one who's essentially had his hands and feet amputated; said-Stikbot keeps saying he's so cold before eventually dying from his wounds.
Tear Jerker - Striker finding the abducted Stikbots in Season 2 Episode 11, all dead save for one who dies anyways after thanking Striker for finding them. Striker's cry of anguish as he angrily beats down a Metalbot afterwards adds to the emotion. The fact that Raptus betrays him seconds later doesn't help either.
The Woobie - Raptus. It's obvious that being the sole survivor of the Off-GRID exploration team has taken a toll on his mental state, and being constantly beaten by off-GRID entities has taken it's toll. Turns into a Woobie, Destroyer of Worlds by the Season 2 finale, after being tired of his weakness.
