Sentinel Prime suffered severe psychological damage in the incident where Elita-1 was lost. Since then, rabid fear of organics and guilt over leaving Elita-One to die have been gnawing away at his neural nets, turning him into a paranoid wreck who's convinced he's the Only Sane Man. Or maybe he's just some self-centered jerk who won't take responsibility for his actions. A slight riff on the former: Sentinel and Elita-One were romantically involved (you see his arm around her waist and he puts in every effort he can to protect her, even covering her and Optimus' retreat. When she fell to her 'death,' he's willing to throw himself into a damn inferno to save her.) Yeah, he took her death pretty hard, especially since his and Optimus' rule-breaking (going to that off-limits planet) caused Elita's death. Now, in the present, he's convinced that rule-breaking will always cause heartbreak. That's why he's so obsessed with regulations and order, to keep others from suffering that same loss. He wants to do good in that regard, but he does need a little guidance; after you realize that, it's hard to hate him. Alternate Character Interpretation, indeed.
Some more Transformers Animated specific examples: Do Lugnut and Blitzwing merely work together, or are they genuinely friends? Is Blitzwing crazy because he's a triple-changer, or is he able to triple-change only because he's crazy? Or are his nuttiness and ability to triple-change unrelated? Derrick J. Wyatt stated that becoming a triple-changer means going crazy in response to a question on his blog.
There are plenty of interpretations regarding Megatron, in large part due to how — probably deliberately — ambiguous a lot of his characterization comes off as. Is he really dedicated to the cause of the Decepticons, or is he merely a power-hungry bastard who uses empty rhetoric to hide the fact that he's out for himself first and foremost? Is his apparent affability genuine or just a very good mask? Is his seeming lack of gratuitous cruelty a sign that he has redeeming qualities, or an extension of his pragmatism and self-control? That being said, this is largely for the show itself; supplemental materials (especially some tie-in comics and released material about the planned Season Four) seem to generally lean towards a more monstrous and unpleasant characterization for him.
Invoked with Blackarachnia's last scene. Waspinator was destabilizing due to the Transwarp energy she infused him with, and was close to exploding. Blackarachnia encased both herself and him in web, lessening the explosion. Optimus says she did that to save them, sacrificing herself, Sentinel says she did it to harness the energy and teleport out, sacrificing Wasp.
Animation Age Ghetto: Back when the first promos were shown off, many fans claimed that the show would be too "kid-oriented" based off of the art style alone. Then Thrill of the Hunt aired and the show got darker in general, and these claims became less frequent.
The Dinobots, to the point where they were easily beaten by Jetfire and Jetstorm and scared off by post-upgrade Sari by Season 3. Oh, and according to Grimlock's profile, he's as powerful as Megatron.
Most of the Decepticons suffer from this. Blitzwing and Lugnut are the worst cases, they are shown to able to beat all five of the main autobots on their own, and since the Autobots getting their asses kicked all the time would get old, beating them has to constantly require the use of plot devices that render both villains to Butt Monkeys
Blackout suffers this in the Cool comic, where Jetfire and Jetstorm dodge his attacks, and combine to take him down. Blackout killed 3 bots the size of Omega Supreme in the war by himself, and lead a bombing raid against a fourth, and he seems to forget that he's covered in weapons.
Sentinel Prime, the shows biggest Jerkass. Fans Love to Hate him, feeling his arrogance coming back to bite him is entertainingly karmic, his mannerisms adding to the moral layers of the Autobots, showing they're not all squeaky clean, and his occasional points of clarity, specifically his reaction to Blackarachnia adding a surprisingly emotional depth to him. Others hate him because he's an obnoxious Damsel Scrappy who refuses to learn from his actions and is a danger to everyone.
The reveal of The Motor Master's design met with some contention. There were fans of the design, using the Voyager Optimus Prime gave him a beefy Evil Counterpart appearance. There was also a number of fans who didn't like the design, some felt that the blocky head clashed with the more curved design of the body, with those fans feeling the use of the Wreck Gar mode to be more suitable. Finally other fans feel that complaint applies more to the character model rather than the toy.
Jetfire and Jetstorm. Some thought they were a cool addition to the cast being Autobot Jets, and combiners who had a number of awesome and funny moments. Others found their comedy relief annoying, felt they were overpowered and benefitted too much from The Worf Effect.
Big-Lipped Alligator Moment: Slipstream appearing for a brief minute to shoot down Optimus at the end of "Endgame, Part I". This is an artifact from a deleted scene in which Slipstream would've revived Starscream at the end of "Endgame, Part II".
Broken Base: The art design for the show, especially for the Transformers themselves. It is either a refreshing new take on the characters with some enjoyable zaniness, or it is too different from what came before and that same zaniness apparently making it not feel like Transformers anymore.
For many fans, the late Fred Willard as Swindle. Willard brings all his best acting chops to make a two-episode character one of the best modern takes on a character who is one of the few to outshine the other members of his combiner team and stand on his own. Many had hoped that Willard would one day reprise the role in a different series, but sadly this never came to be when Willard passed away in 2020. His death was taken so hard by the fandom at large that youd think they were grieving one of the creators of the franchise. TFWiki.net even made Swindle the featured article on their main page for some time after Willards death.
Corey Burton's Role Reprise of Shockwave also solidified him as the definitive actor for the character for many fans, much like Peter Cullen and Frank Welker as Optimus Prime and Megatron. His successor, David Sobolov, even admitted he could never outdo Burton and resolved to provide his own unique take on the character to not be in Burtons shadow.
While Mark Ryans take on Lockdown in Age of Extinction would be well-received, few would argue that anyone can outdo Lance Henriksen as the character he helped originate.
Catharsis Factor: Anytime Sentinel Prime gets his skid plate tossed around is immensely satisfying, seeing how big of a Jerkass he is. The worse he suffers, the better.
Megatron is the cruel, ruthless leader of the Decepticons and the Autobots' worst enemy. A megalomaniac who overthrew the generally peaceful leader of the Decepticons to make them his own, Megatron spurred them into all-out war against the Autobots, leading to heavy casualties on both sides. Megatron utilized chemical weapons that wiped out entire battlefields—even his own men—and air bombings on civilians during the Great War. After resurrecting himself on Earth, having caused much destruction to regain his body, Megatron makes several attempts to invade Cybertron, culminating in him ordering Decepticon attacks on several Autobot bases throughout the cosmos while he personally invades Cybertron and destroys its Autobot leaders, planning to test his new Omega Supreme clones by first annihilating Detroit.
Lockdown is a ruthless and sadistic Bounty Hunter whose only loyalty is to himself. Unaligned with Autobots or Decepticons, Lockdown is indiscriminate in his prey, taking commissions from whomever is willing to pay him. To make himself more powerful, Lockdown steals upgrades from his targets, torturing them by cutting the weapons from his victims' bodies. Devoid of empathy, Lockdown sees his victims as little more than trophies, taunting them if he chances to encounter them again. Having once been a student of the Autobot Yoketron, Lockdown murdered his former master in order to steal the protoforms under Yoketron's protection and sell them for his own profit. Merciless and consumed by greed, Lockdown is a sociopath who frightens and disgusts Autobots and Decepticons alike.
Meltdown, originally Prometheus Black, is a human scientist who ended up mutated by his own experiments. He tries to kill his rival, Isaac Sumdac, in a fit of rage whilst blaming him for all his problems, including his self-inflicted transformation. Later, he becomes so obsessed with creating a human transformer, he not only mutates at least two innocent humans—one of them his own lawyer—into gruesome hybrids combined with animal parts, he also decides to kidnap Sumdac's innocent eight-year-old daughter as his newest test subject, deciding to experiment on children in general now. When Blackarachnia breaks him out of jail in exchange for him eliminating her organic half, he double-crosses her and tries to destroy her Transformer half—a deed which, if not destroying her soul completely, would have left her with a completely organic body she's disgusted with. He also forces the Dinobots to work for him by painfully burning them with his acidic touch until they follow his commands. He hurt them so badly that they were willing to turn on Bulkhead and Prowl, their only friends among the main cast, just to stay in Meltdown's good graces.
For whatever reason, Longarm/Shockwave and Blurr, even though their only scene together is of Shockwave trying to kill Blurr without remorse. Hilariously it's become one of the most popular pairings for the Animated fandom, even beating out old favorites like Megatron/Starscream and Jazz/Prowl. Even the pairing's fans aren't sure why!
Apparently, quite a few circles ship Megatron/Optimus and Blitzwing/Bumblebee.
Cult Classic: Animated didn't achieve the same kind of pop culture dominance that many other iterations of the franchise have, but a decade after its release it retains a very strong following within the greater Transformers fandom due to its surprisingly strong storytelling, unique take on the Transformers mythos, and abundance of geeky Shout Outs, Homages and Mythology Gags thrown in for the older fans to catch.
Damsel Scrappy: Sentinel Prime is an unusual male (not to mention giant alien robot) example. Most of his time onscreen involves him getting into some scrape or another and having the long-suffering Optimus get him out. It seems the only thing that keeps Optimus from abandoning him is a sense of guilt about their shared past and perhaps some level of fondness for his old Academy-mate.
Mix of all of the above, and the hope that Sentinel gets it through his thick head that his arrogance is a Bad Thing. But Status Quo Is God and he always rubber bands back to being a jackass by his next appearance. Even Jazz, who has long tolerated (or ignored) it as his second in command, finally gives up and more or less defects to Prime's crew.
Designated Villain: Played With for Prowl in "Five Servos of Doom." He's supposed to be an undisciplined maverick who learns to be more humble and fight for a good cause under Yoketron, but the reason he's brought to Yoketron in the first place is because he's a draft-dodger. Prowl states he doesn't want to fight in the war, and he's shown to have been rounded up and forced to participate. Warpath, the arresting officer even threatens to take him outside and beat him up until he agrees. In essence, he was pressed into service and villainized for not wanting to go out and risk his life for the people forcing him into the war. On the other hand, the Decepticon threat was so great that the Autobots were reaching the Godzilla Threshold, what with Project Omega, and were forced to make certain moral concessions, so the Decepticons wouldn't win and make life even worse for people under their oppression. Forced military service was just one of these moral concessions, all for the greater good.
Captain Fanzone is also pretty well-loved by the fans.
Amongst the non-Decepticon villains, Meltdown seems to be the most popular due to being a terrifying Knight of Cerebus who can actually hold his own against the Autobots rather than being a joke villain like Angry Archer or Professor Princess. And he can dance!
Slimy, bug-eyed Swindle, too! Can you believe it!?
Fan-Disliked Explanation: Defied. Word of God is that avoiding this reaction is why the AllSpark has no given origin, to not run the risk of making the artifact less interesting or making it too bizarre and convoluted.
Fanfic Fuel: With the amount of characters with their own quirks even if they're exclusive to All There in the Manual, there's at least a couple of pieces of fanart and/or fanfiction that you'll find lying around somewhere of them. It at least rivals that of the Generation 1 buzz.
Growing the Beard: Season One wasn't bad by any means, and had a few stand-out episodes (in particular "Thrill of the Hunt", which introduced Lockdown and dealt with mature themes like consequences and regrets during war time), but Seasons Two and especially Three were when the series found its footing, introducing Darker and Edgier themes, more serialized storytelling and character development, and largely ditching the one-note human villains of the first season in favor of a more consistent focus on the Decepticons as the main villains.
Megatron once mockingly told Starscream that he "couldn't lead a parade" during the latter's infamous Death Montage. Cut ahead to Transformers: Cyberverse, and a parade actually plays a key role in that show's final season, specifically by said parade actually being a Lotus-Eater Machine designed to drain the Autobots and Decepticons of their life force, and create a Quintesson Judge that will destroy the universe. And who's part of said judge? Starscream.
Tom Kenny's take on Wasp has been well-received, in spite of the Memetic Mutation by younger audiences about how Spongebob and Starscream have the same voice. Meanwhile, reception on his take on Starscream is seen as take it or leave it, though some are impressed that with him channeling Chris Latta.
For younger audiences that have never seen his other works (such as Gargoyles), Bill Fagerbakke's performance as Bulkhead is this.
Safeguard's look reminds many people of Kamen Rider Double. One person even modded their Safeguard into CycloneJoker colours.
The casting of Corey Burton, the voice of Shockwave on Generation 1 as Megatron. Recently in Dark of the Moon, the G1 incarnation of Megatron's voice actor, Frank Welker, returned the favor and voiced movie Shockwave. note Though Burton was asked to reprise the role for that film, he turned it down.
One of TF Wiki's earlier image captions for Lugnut describes him in relation to Shockwave and Omega Supreme. This becomes amusing when Animated Shockwave is introduced and Lugnut feuds with him on who is Megatron's most loyal servant. And then the last episodes have the creation of Lugnut Supreme, based on Omega Supreme, which involved both Lugnut and Shockwave.
Lugnut is fanatically loyal to Megatron in the series. Several years after the end of Animated, a new incarnation of Lugnut in the IDW G1 continuity becomes a part of Deathsaurus' army in More Than Meets the Eye, who are dead set on murdering Megatron after his defection to the Autobots.
In "Human Error Pt. 2", both Optimus Prime and Soundwave battles using The Power of Rock (complete with guitar shredding). Fast forward to 2014, and we got another one from Hasbro... in the form of a My Little Pony: Equestria Girls short involving Rainbow Dash and Trixie in a guitar shred-off!
Speaking of MLP, there's a villain who uses a robot unicorn that shoots lasers to commit crime. You know it's funny when you realize that Sari's VA voices a certain purple unicorn.
It also serves as a sort of retroactive Reverse Funny Aneurysm moment when you consider two things:
1. Before this episode, Beast Wars introduced Tarantulas, who at least once tried to drain the mech fluids of a Maximal in a vampiric manner. and 2. During that same time, a cartoon called Vanpires aired, about - you guessed it - mechanoid vampire cars that drained the motor oil from helpless vehicles.
"Till All Are One": In Transformers Animated, Elita-1 has the power to download every Cybertronian's special ability, indeed.
Lockdown's appearance was partially inspired by Boba Fett, and was in a rivalry with Ratchet, who was voiced by Corey Burton. Around the same time as this series, Cartoon Network was running a Star Wars cartoon that had a few bounty hunter dedicated episodes, including around Boba Fett. Both shows also not only featured Burton in prominent roles as the lead villains, but Burton would get to voice the character of Cad Bane—another bounty hunter that was originally envisioned for Lockdown's original voice, Lance Henriksen!
Hollywood Homely - Blackarachnia, at first. She's supposed to be hideous due her techno-organic status, but both to the viewer and most of the Autobots she's a beautiful Femme Fatale. And then her helmet comes off and this trope is subverted so fast its head spins.
Megatron is the leader of the Decepticons and the Arch-Enemy of the Autobots. A brilliant tactician who kickstarted the entire Decepticon cause into an organized, deadly army and initiated the Great War, Megatron was reduced to but a head after the betrayal of his lieutenant Starscream; however, even this doesn't stop Megatron, as he manipulates Isaac Sumdac and several other humans to reconstruct his body and return to life. Megatron is constantly updating and adapting his plans, going from trying to steal the Allspark to using its shattered fragments to create a Space Bridge with ease, and uses the mole he planted in Cybertron ages ago, Shockwave, to construct Decepticon uprisings so as to distract Cybertron and let Megatron invade. Rarely losing his cool and his plans always being foiled only by an outside source he couldn't have predicted, Megatron makes one final scheme by using rudimentary tech to take control of Omega Supreme, create clones of him, then use them to conquer Cybertron before expanding the Decepticon rule across the cosmos.
Shockwave is Megatron's "most loyal servant", a manipulative shapeshifter who infiltrates Cybertron as the Autobot Longarm. When Bumblebee learns that there is a Decepticon spy in their midst, Shockwave first tries to murder the bot before framing the innocent Wasp as the spy, successfully protecting his identity to such a point that he murders the current head of Cybertron intelligence to get himself the promotion with no suspicions. Shockwave manipulates the Autobot leadership for years as he orchestrates Decepticons across the galaxy, and always pounces on any potential leaks of his identity, leading Blurr into a lethal trap when he tries to investigate Longarm and cutting off communications with Optimus Prime when his team learn of Shockwave's status as a mole. When realizing he is moments away from being exposed, Shockwave deals a fatal blow to Ultra Magnus, kidnaps Arcee and uses her memories to help Megatron with his plans to clone Omega Supreme, only being beaten after he lures an Autobot team into a trap and nearly murders them all by playing on their compassion.
Swindle is a fast-talking, smooth arms dealer who plays both sides of the Autobot-Decepticon conflict to bring himself the most profit. Introducing himself by manipulating a group of human villains into building a powerful EMP weapon, Swindle betrays them all and tries to sell the weapon to Megatron, demonstrating its abilities by easily incapacitating the entire Autobot team. Though he is captured thanks to a surprise attack, Swindle bounces right back as he stages a breakout of an Autobot prison ship, taking control and planning to use the Autobot crew as hostages before harvesting their parts for extra cash. Swindle is always ready with a new gadget or weapon to get out of any situation, such as arming the Decepticon prisoners or disabling Jetfire and Jetstorm in a cinch, and he ultimately gets away scot-free, using an Autobot rescue attempt to distract his cohorts, looting the entire prison ship's belongings, and fleeing into space while remarking how much he "loves a shopping spree."
Memetic Mutation: Shockwave's difficult to hear and completely out-of-character "LIAR! LYING LIAR!" has become a bit of an in-joke amongst his fans.
It was a big deal for younger audiences during the show's airing that Starscream and Bulkhead were voiced respectively by Tom Kenny and Bill Fagerbakke of Spongebob Squarepants fame, prompting several Spongebob and Patrick jokes and videos about the duo.
#reviveTFAexplaination A hashtag created on May 23 on Twitter, this was used by fans to support a potential 4th Season revival.
Among the Autobots, Wreck-Gar is very much this. It sounds weird that a sentient Humongous Mecha voiced by "Weird Al" Yankovic could be cute in the first place, but Wreck-Gar is so Adorkable and kindhearted that it's absolutely darling. Fair warning, watching him may make you want to go out and hug the nearest garbage truck.
In "Predacons Rising", Blackarachnia jumps off the slippery slope by mutating a mentally unstable Wasp and then casually admitting she doesn't care if he lives or dies so long as she could find a cure for herself. Her oft-teased redemption was pretty much dead by that point.
Prometheus Black decides to use the child of his "arch-nemesis" as the test subject for making an organic Transformer. This is after he already tried it on two adults and permanently left them in misshapen bestial forms.
Most Wonderful Sound - This is the first time the Autobots themselves have mentioned the iconic transforming noise. When the Bots are trying to will themselves back to their normal states in Soundwave's Lotus-Eater Machine, Bumblebee suggests that Bulkhead make the noise with his mouth.
My Real Daddy: Bulkhead was the name of a major character in Transformers Energon, who was older, and with a different alt-mode. The series' vastly different take on the character as The Big Guy with an artistic streak, however, was well-loved, and later incarnations of Bulkhead take more after this one than his Energon counterpart.
Narm Charm: The series' approach to combining humour with drama makes the whole thing remarkably cheesy, but there's something inherently lovable about the way much of the main cast (and that includes many of the villains) are nobodies, screw-ups, and nutjobs.
Team Athenia and Team Chaar. And they would've gotten more appearances if the show had continued...
Tracks with a snobby accent running away from Ratchet and Captain Fanzone in "This Is Why I Hate Machines".
Also from "This Is Why I Hate Machines", Flareup and Grandus trying to squish Fanzone.
Warpath's only major appearance in "Five Servos of Doom".
The Problem with Licensed Games: The Nintendo DS game has rather mixed reviews. While lauded for the graphics and story being faithful to the show as well as having the show's cast reprise their roles, it has also been criticized for being too easy and mainly being a puzzle game with very little transforming.
While they did help stave off Villain Decay and Menace Decay for the Decepticons, the human villains are generally disliked for being gimmicky and taking screentime away from the Transformer vs. Transformer conflicts. The sole exception seems to be Meltdown, since he's actually dangerous to the Autobots and serves as a menacing villain in his own right. Technically speaking though, he's not human-at least not anymore.
Averted with Sari Sumdac. Unlike most human characters in the franchise, Sari has largely avoided being The Scrappy. Of course, it was eventually revealed that she's really half-Cybertronian.
Squick - Captain Fanzone dangling a loogie towards Rattletrap, and sucking it back in when the latter telling him what he wants. Excuse me for a sec....
In "Predacons Rising", Sentinel discovers Blackarachnia's true identity Elita-1 and that she has just transformed Wasp into Waspinator via her transwarp chamber (he was manipulated into it). Despite the former revelation, Sentinel, being an organic-phobe, is actually willing to kill Blackarachnia, to put an end to all this. While his approach to the situation is most certainly wrong, given how she hasn't actually harmed him yet, he does have something of a good point in this line below, given what she's just done to Wasp:
"Don't say that name! You don't deserve to say that name! You're not Elita-One, you mutant freak. Elita-One went off-line a long time ago."
The villain Meltdown's anti-robot crusade was due to robots taking manufacturing and service jobs from humans, in a city with the highest unemployment rates in the country.
Megatron is a compulsive manipulator and liar but he isn't wrong at all that Autobot society is authoritarian and borderline fascist. Besides corrupt, organic hating higher ups like Sentinel Prime, Autobot High Command uses sentient beings like Omega Supreme as living war-machines, treats prisoners so terribly they broke Wasp's mind, and is apparently so bigoted toward organics Blackarachnia felt more comfortable with the Decepticons than them. The Decepticons' quota as "freedom fighters" certainly must've come from somewhere.
Take That, Scrappy!: Rodimus Prime, in his first appearance, ends up getting afflicted with cosmic rust. This has satisfied some fans who don't like Rody.
When Takara Tomy announced that they were tying Animated (well, their handling of the show) with the movie-verse, change in episode order and renaming Bulkhead to Ironhide (even though there was already an "Ironhide")... Well...it sure did help that the Japanese dub didn't turn out to have any major tie-ins with the movie-verse at all and had some awesome music by JAM Project. What actually ended up going on: change in episode order and Ironhide rename still happened, fans were also annoyed by cuts to the episodes made in favor of live action segments featuring the Ototbotto family. There were also various instances of Cultural Translation and some characterization changes made, like Bulkhe—uh, Ironhidebecoming more of a simpleton than the original Bulkhead and Bayformer Ironhide ever were.
To say that some fans were not pleased when it was revealed that in this show's universe Optimus was not the Big Good of the Autobots but just a low level commander would be the understatement of the decade.
They Wasted a Perfectly Good Character: Blackarachnia in the "Megatron Rising" two-parter. All her appearance amounted to was creating a continuity error (e.g, she wanted to be fully mechanical again, which is what she already tried doing in her formal debut, but it wound up almost killing her; unlessthat's what she wants) and getting Sari to the Autobots faster to help them. One wonders if she was forced into those episodes.
They Wasted a Perfectly Good Plot: Sari's upgrade, and her backstory in general. We never see the immediate fallout of her upgrade and near-overload, since she vanishes for four episodes afterwards, and we never find out how she got to Earth in the first place. You can blame Executive Meddling for that: they demanded that the human characters be shoved to the background to focus on the characters with toys for the third season, including Sari.
Too Cool to Live: Prowl and Blurr. At least it seems that way for the latter. The comics reveal he was never actually killed and was given a new body later.
A few major ones (mainly, since it's not a Beast Wars-type series, nobody could have expected Blackarachnia in the main 'con lineup) but one standout among the "generic" bots. They're almost all based on G1 characters, some more obscure or from the Japan-only sequels, but then there's the Autotroopers (seen in Sentinel's propaganda video). They hail from the INCREDIBLY not-kid-friendly, not-brain-friendly Kiss Players Japanese radio series and its accompanying manga pages. (Their presence isn't what made it that way, but KP is just the last thing you'd expect a kids' show to make a Shout-Out to in any way.)
Waspinator being The Rival to Bumblebee and a normal-looking bot that is revealed to have gone crazy like his Beast Wars counterpart at the end of his debut episode... with his next episodes having him become just like the original Waspinator.
Optimus Prime in "Megatron Rising, Part 1". While he did grab the Jerkass Ball pretty hard, and gets rightfully chewed out by Bumblebee for his behavior, he has every reason to be upset as he did. Not only are the Decepticons on the verge of an attack, but he just learned that Bulkhead and Prowl lied to him about hiding the dangerously powerful Dinobots—a pretty serious breach of his trust. Not only that, but considering his decision to take Sari's key was specifically because he wanted to use its healing powers in their upcoming battle without needlessly putting her life at risk, and both Sari and Bumblebee have been particularly irresponsible throughout the series up to that point (namely with her using the key to do virtually whatever she wanted in spite of the consequences, and his impulsiveness constantly getting him into trouble), he's not entirely wrong.
Sentinel Prime in "Predacons Rising". The guy is an absolute jerk of a bot, he's partially responsible for her mutation, and his cut towards Blackarachnia is a pretty deep one, considering they were once very close. Yet, as noted under Unintentionally Unsympathetic, her actions up to that point have shown she's fallen pretty deep into villainy, and seems to have no regrets over it. Yes, Sentinel is horribly racist towards organic life, but seeing as Blackarachnia has committed all sorts of acts of villainy, "Elita One" did go offline a long time ago. What's especially deep cutting is that she has no regrets about what happened other than how it personally affected her, but Sentinel feels he crossed the Moral Event Horizon, and what he did back then was inexcusable. It's pretty jarring that a gigantic jerkass is (eventually) willing to accept his role in the whole affair, but she isn't.
Blackarachnia/Elita One: Although her anger at being left to die is understandable and it's understandable that her goal is to restore her body to its original form, that is no excuse for some of her actions. Some of which include, using the Allspark Key to try and purge her organic half which drain the lifeforce of every organic around Detroit, throw Sari off a roof for annoying her and tricking Wasp into thinking they're friends so she could experiment on him and make him part organic as well. Not to mention, Optimus did warn her and Sentinel about the planet being dangerous and that she shouldn't use her download ability on the organic spiders. But she did both anyway, so really she only has herself to blame for what happened to her.
Sari in Megatron Rise Part 1: Sari is a sweet, smart and brave kid. But she tends to overuse the power of the Allspark Key whenever she can and can be a bit of a brat about it sometimes. In previous episodes throughout season 1, she's told not to abuse its power, but she does it anyway which leads to a big disaster and once the disaster is taken care of she says that she'll use the power of the key more wisely... only to abuse its power the next episode or so. In this episode, Optimus becomes so mad that Prowl and Bulkhead disobeyed his orders and lied to him that he becomes a jerk and one of the first things he does is want Sari to give him the key so they could use its healing powers for the upcoming battle against the Decepticons. But Sari refused to give it up, insisting that she'll be more responsible. (Again.) Thus, Optimus told Ratchet to use his magnetic powers to take the key by force. Naturally, Sari was heartbroken by their lack of trust, but it's hard to blame Optimus if you remember the previous episodes. Optimus may have taken a level in jerkass, but he has a good point in this regard.
Wasp/Waspinator, to some extent. His Sanity Slippage and transformation into Waspinator was tragic and horrifying, but this is somewhat undercut by the fact that Wasp was a cruel, selfish, bullying Jerkass as an Autobot. He hated Bumblebee for pretty much no reason at all and would even dismantle his parts for fun. Had he not been framed, there's a chance he would have gone on to be just as bad, if not worse than Sentinel Prime himself. As Bulkhead puts it:
"You may not have been a traitor, but you were never a good bot."
What an Idiot!: As awesome as the scene is, Megatron gets one when he supposedly kills Starscream, and has him thrown out like garbage. Starscream revives due to the Allspark fragment in his head, and proceeds to try to kill Megatron again. You'd Expect: Megatron if not immediately to realize after at most 2 subsequent deaths that Starscream returning from death is not just a fluke and to take Starscream's "dead" body and lock it up to try to figure out exactly why he keeps coming back from death over and over again, or at the very least just blast him into slag to make SURE he's dead. Instead: Montage ensues of Starscream attacking Megatron, Megatron effortlessly "killing" him, and throwing him out like garbage over and over again. Starscream himself gets his own What an Idiot! for continuing to blindly attack Megatron repeatedly before FINALLY realizing that a straight-up attack is never going to work.
What The Hell, Casting Agency?: This was the initial reaction to David Kaye voicing Optimus Prime, since previously Kaye's best known Transformers roles were voicing the Beast Wars and Unicron Trilogy incarnations of Megatron. Kaye himself admitted that even he had expected that the show's creative team wanted him for Megatron and he was surprised when the role he got a callback for was Optimus. However, Kaye managed to win over fans, with his voice suiting the younger, less-experienced Optimus that the series was going for.
