Of course this all gets flipped on it's head once we learn his Backstory Horror. At that point, not only is the sympathetic part taken to whole new levels, but the protagonists start treating him better and he develops into the Token Evil Teammate.
The Cute King and his subjects are trying so hard to be threatening in spite of their inability to charge down a hill without literally coming apart. Finn and Jake take pity on them, on the basis that they'll either win or die, and they're not going to win, and convince a bunch of people to let themselves be "killed", using ketchup to fake the wounds.
When that didn't work, they point the Cute King towards the one person he has any chance of defeating. The Ice King. And he does.
He does get at least one Not-So-Harmless Villain moment in the series, in which he gets a hold of another lamp and wishes that the protagonists get smashed like bugs. When told that genies can't kill, he has a moment of brilliance and asks for the protagonists to be turned into bugs so that he can smash them like bugs.
He also went back in time and rewrote Agrabah's history in one episode so that he could be Sultan.
Aladdin also occasionally had to deal with an inept thief named Amin Damoola (nicknamed "Butterfingers"). The only time Butterfingers was a serious threat was once, when was using magical artifacts supplied by Mozenrath, who had essentially replaced Jafar as Aladdin's main nemesis.
Made even more pathetic by the fact that, in order to get those magical toys (which Mozenrath actually refers to as junk from his closet) Butterfingers has to deliver the Sultan-Turned-Gold-Statue by a timed deadline or become Mozenrath's slave. The kicker is, as stated during one of Mozenrath's scenes in the episode, the evil wizard doesn't really care which scenario happens. This is just spring cleaning for him.
Angela Anaconda: Nanette Manoir may come off as this, since, while she is an Alpha Bitch, her actions are rather tame and in-line with what would be expected of kids her age. Angela, meanwhile, fantasizes about humilating her, tormenting her or even sometimes killing her in the most brutal ways she can think of.
He has a few positive experiences even in the first season, and got so much screen time not directly related to suffering or fighting the Gaang that he was practically a main character all along. He was even allowed to win against the other villain and get his first CMOA.
Killer Moth from The Batman is given this treatment when he joins "Team Penguin". All he's ever shown doing is using a cocoon gun that continuously backfires on him and make coffee for the Penguin. This changes however, when some chemicals change him into a giant moth mutant.
Harley Quinn tended to fall into this trope, especially when she caught on as a popular character. She was often treated as genuinely misguided, so the audience sometimes forgave her for her more violent behavior depending on how softening a particular episode was.
In the comic-turned-episode "Mad Love", Harley did manage to succeed in trapping Batman. Batman's only hope was to have her inform The Joker, who he knew would free Batman because it wasn't HIM that defeated Batman! Batman even admitted that Harley came closer to killing him than the Joker ever did. Harley also suggested just shooting Batman, instead of elaborate death traps. Ironically, at the end of the episode, Harley almost succeeded in killing Bats with an elaborate death trap, while the Joker, who previously slapped Harley for even suggesting such a thing, tried simply shooting him...and failed.
"The Man Who Killed Batman" was focused around Sidney Debris AKA "Sid the Squid", a nebbish and meek bumbling mob underling who dreams of being a bigshot. He gets his wish when Batman is apparently killed and his gang believes Sidney did it. Unfortunately, as Sid finds out, that reputation comes with a price... The episode has a happy ending for Sid, however. He still goes to jail, but Batman lets everyone keep believing that he almost killed Batman and made a fool out of the Joker, turning Sid into a celebrity in prison.
ALL of the "villains" from "Make 'em Laugh", though they're only villains because they were brainwashed by The Joker. They're all pretty ineffective, but most notably is the "Condiment King". Even Batman takes pity on the guy.
Police Radio: Suspect is a male costumed extremist armed with what appears to be a... ketchup gun.
Batman: It's gonna be one of those nights.
Ben 10: Alien Force: though he does becomes a threat on occasions (he was actually dangerous in his first two appearances), Albedo was this from the beginning and becomes more so as the story goes on. He is doomed to be trapped in a human body he despises, and all he wants is getting his original form back. As a matter of fact, when he finally gets his form back in one episode, he makes it clear he has no more reason to fight Ben, and prepares to leave Earth... only to immediately revert to human form.
King Max from The Biskitts, is like a royal version of Gargamel.
Of the primary villains of the earlier series, No-Heart and his niece Shreeky don't count. No-Heart was a legitimately powerful and evil sorcerer who had a habit of blasting Beastly with lightning bolts whenever he screwed up; and while Shreeky never actually did anything evil, she was a Spoiled Brat with a voice so loud that she made No-Heart wince. Mr. Beastly, No-Heart's primary lacky, definately fits somewhere between here and Butt Monkey. In the one episode that Beastly had, with him in the spotlight, him infuriates No-Heart by breaking No-Heart's crystal amulet (which is the source of his shapechanging spells), then breaks No-Heart's throne (something he knows No-Heart will be livid about), get turned into a horrific mishmash of animals while using No-Heart's broken amulet to catch some of the Care Bears, then be blackmailed into letting the Care Bears go after they tape-record him chanting a litany of "I care" to break the broken spell and be turned back to normal, and then, when No-Heart arrives, having calmed down due to finding an even more powerful crystal, he sits on his crudely repaired throne...and it breaks to pieces. Meaning more electroshocking for Beastly.
Dark-Heart from the second Care Bears film could qualify too. While he was an effective villain at first, all that went out the window when he almost fell on the side of the boat as a human. Then later on he was little more than a generic Smug Snake who was won over by The Power of Friendship. The Nostalgia Critic said it best.
The Toilenator from Codename: Kids Next Door badly wants to be a villain, but is far too wimpy and incompetent to pull it off. He's a minor inconvenience to the KND, and most of the bad guys try not to be seen with him because of his clingy Bumbling Sidekick personality.
He's a Not-So-Harmless Villain though, as he's able of using his "toilet powers" to "flush" the entire Grand Canyon with milk.
He also managed to defeat the five main characters by himself on one occasion after getting fed up with being treated like garbage. Only not really. He beat the entire team of villains on his own, mistaking them for the kids.
The Box Ghost of Danny Phantom draws the line between this and Harmless Villain. He has the potential to be a great baddie (if one episode and his badass future self is any indications), but he just never makes it. Out of all the ghosts Danny has fought, Box Ghost is strictly in the "Who Cares" category, but he tries, he oh so tries.
Dr. Reginald Bushroot of Darkwing Duck. He mutated himself in an attempt to impress a girl. When that went about as well as expected, most of schemes throughout the series involved trying to grow a companion or feed his plants. He certainly seemed like a nice enough guy most of the time, only turning violent when Darkwing tried to stop his plans.
It should be noted though that for all his sympathetic qualities, Bushroot is one of the only villains to have successfully committed murder. Granted his victims were the jerk doctors who made fun of him, but as the other villain in this category is Knight of Cerebus Taurus Bulba, this is still a rather shocking feat.
Like Tom above, Donald Duck can sometimes come off this, especially when he crosses paths with Chip 'n Dale. Sometimes Donald does start the fight, other times he just ends up getting picked on and losing.
The titular organization of Evil Con Carne. While Hector's plans are genuinely evil, when they end up being utterly pathetic when acted them out. In fact in one episode, Hector and his army are defeated by angry children and a Mr. Rogers Expy.
The Lobe, archnemesis of the titular character in Freakazoid! Despite being fiendishly brainy (quite literally - pretty much his entire head is made up of brain), he's extremely sensitive and insecure, and Freakazoid was once able to defeat him with nothing more than some harsh verbal criticism of his scheme.
Frisky Dingo's Killface is a pseudo-cultured, incompetent supervillain whose plans are often derailed by trivial matters and lacks knowledge of common subjects (it's a revelation to him that P.C. stands for "personal computer"). He's still more likable than "hero" Xander Crews, though.
Killface is so sympathetic, especially when compared to Jerk AssDesignated Hero Xander Crews, that it's easy to forget that he brutally killed two people in the pilot and has added to his body count throughout the series. It helps that some of the other members of the cast have committed similar misdeeds and/or are Asshole Victims.
G.I. Joe: Cobra Commander, who was constantly mocked, ignored, or pushed aside not only by other would-be world conquerors, but by his own minions.
Of course, he was never anything but effective and unsympathetic in the comics, where, among other things, he killed his own son. Oh, and he used to be a used car salesman, thefiend!
He does get the ineffectual part still - sometimes as part of a plan, sometimes because it's an imposter performing poorly. And sometimes, Destro just plain doesn't like him, and is willing to take the loss just to make him look bad, mostly because of his 'thing' for the Baroness.
The miniseries G.I. Joe: Resolute is also a subversion. Cobra Commander actually has a speech where he claims his previous incompetence was just an attempt to force his minions to think outside the box. He wipes Moscow from the face of the Earth just to prove that he could, and by the end of the series, he's so unhinged that he's hacking his own men apart with a sabre. His plan still failed, of course, but holy shit was he badass.
On Goldie & Bear, The Big Bad Wolf, a.k.a. "Big Bad.", is this with a heavy dose of Jerk with a Heart of Gold. Sure, he's regularly a pest to both the Three Little Pigs and Little Red Riding Hood. However, he schemes are rarely effective and when they do work, he's often regretful. He's also shown several redeeming qualities, including being willing to try niceness and being apologetic and helpful after realizing that he's acted like a jerk.
Gravity Falls's bumbling time traveler Blendin Blandin, in his second appearance as an antagonist. Made more sympathetic by the fact that he's mostly right: the kids did ruin his life, and stealing the time machine and intentionally ruining the past were objectively crappy things to do.
Skeletor in He-Man and the Masters of the Universe (1983)despite having a face that Standards & Practices must have had fits over, was so ineffective that the writers felt sorry for him. One stated in an interview that part of the reason they wrote a few Enemy Mine episodes was that it was the only way they were allowed to have Skeletor come out ahead for once. He was so feeble at villainy, in fact, that the show resorted to two replacement villains: King Hiss of the Snake-Men, and Hordak, who suffered severe Villain Decay after his introduction. Neither were exactly scary themselves, but miles ahead of Skeletor.
Subverted in the 2000-era re-imagining. While Skeletor's still a Card-Carrying VillainSurrounded by Idiots, and Evil-Lyn is clearly his mental superior, Skeletor's clearly a threat this time around and every bit as powerful, terrifying, and evil as he claimed to be, having destroyed half of Eternia before the show starts, and twice defeating the Big Bad that the heroes themselves could not. While still sometimes played for laughs, and never shown as even 1/10 as threatening as Hordak, Skeletor crossed the line, at least.
Invader Zim qualifies for this trope most of the time; more often than not, his schemes are thwarted by the Ditz portion of his Genius Ditz personality, rather than by his arch-nemesis or his Cloud Cuckoo Lander robot. Of particular note is the episode where he survives a Training from Hell in order to receive some Humongous Mechas from his leaders, only to be shot into a sun for his troubles.
In Jackie Chan Adventures, the Dark Hand Enforcers are a bunch of incompetent gangsters who repeatedly get their butts kicked by the good guys, while constantly being forced by greater and more sinister villains to do their bidding.
Lucius Heinous VII on Jimmy Two-Shoes. Despite literally ruling Miseryville, the main characters either don't fear him or don't respect him. He desperately tries to be the Big Bad, but fails horribly. He is pretty much an incompetent version of Satan. Though, while he's largely ineffective, the fact that he keeps people like Heloise and Molotov under his thumb is probably a sign that he's doing something right.
Tabaqui from the 2012 CGI adaptation of The Jungle Book fits this like a glove. He's Shere Khan's faithful henchman who often tries to trick and manipulate Mowgli in hopes Shere Khan eats him and gives him scraps but he's such a Nervous Wreck and the butt of slapstick humor that more often then not, he comes across as a Jerkass Woobie.
Dr. Drakken never gets the respect he thinks he should have; he always fails his capers, sometimes even without the help of Team Possible. He often gets mistaken for the more respected Dementor and, at the end of the series, he is outright told how much of a failure of a villain he has been (despite having come closer to taking over the world than any of his peers, and ending up with much of the credit for saving the world from the Alien Invasion). If it wasn't for his Dragon, Shego, he wouldn't be a villain at all.
Arguably, every villain in Kim Possible is like this, aside from Shego, who's the only one with any amount of competence or fighting ability.
Keeping Shego on HIS payroll should be considered extremely competent, especially when there are villains like Senor Senior Senior, who has Scrooge McDuck levels of moolah.
Of course, after his Arrogant Kung-Fu Guy resume is firmly established and he has shamelessly brutalized the entire rest of the cast, others see this as simple Kharmic retribution. Pride goeth before the fall, after all, and a Humiliation Conga was really no less than Tai Lung deserved at that point.
Voltar and the League of Super Evil. Guy is just so very motivated and happy about every plan or scheme he thinks up, no matter how trivial, that you just have to root for him. I mean, how many villains are ecstatic about throwing an 'EVIL' barbeque and not inviting their uncaring neighbors?
One of the episodes involves a highly convoluted plot by the League...to make the pizza delivery boy late so that their food will be free!
All of them, however, have to be topped by Wile E. Coyote, the epitome of the villainous Butt Monkey. In fact, one of the laws of the Road Runner cartoons is "The audience's sympathy must remain with the Coyote." For a coyote to want to eat a roadrunner is perfectly natural in the order of things, and to top it all off, he was regularly portrayed at the beginning of an episode as rib-thin and starving.
And Sylvester was usually depicted as one of these.
Yosemite Sam was actually a deliberate subversion of the trope, because audiences were starting to favor Elmer too much.The idea was to feel sorry for the guy, but it was getting to the point where Bugs was starting to look like a relentless bully instead of a wiseacre outwitting the buffoon who was trying to victimize him. Sam was both smarter and more belligerent than Elmer, meaning that Bugs was free to lead him on all he wanted. But even Yosemite Sam, while pretty dark for a Looney Tunes villain, was still fairly ineffectual compared to the average non-Looney-Tunes villain.
Nasty Canasta and Rocky the gangster, initially more fearsome subversions of this trope, eventually devolved into hopeless foils for Bugs as well.
Killgore from My Life as a Teenage Robot is an odd example, in that he's ineffectual BECAUSE he's so sympathetic. People are finding him too cute (being that he is a wind-up toy) to see him as a threat, including his self-declared nemesis Jenny. However, he also proves to be a Not-So-Harmless Villain, as he's quite capable of going to extreme lengths, such as somehow managing to rebuild the deadly Armageddroid, to prove he's dangerous.
The episode "Owl's Well That Ends Well" involves the usually-good dragon cub Spike temporarily becoming a villain, but definitely of the "ineffectual sympathetic" variety, with the emphasis on "sympathetic". For context, when an owl named Owlowicious shows up to do some of the work Spike had been typically doing for the girls, Spike ends up getting less attention from them than before, and in turn, resents the owl a fair bit. After being scolded by Twilight for lying about a book not being there, he thinks the owl set him up, and in turn, tries to do the same to the owl, by planting a fake dead mouse with ketchup blood in Twilight Sparkle's room; he gets caught in the act. After running away, ending up encountering a dragon while gone, and then being saved from the dragon by Twilight and the owl, he apologized for the way he was behaving and is back to being one of the good guys.
In part 2 of "The Crystal Empire", his reason for his actions are put in a new light as we learn his greatest fear: Twilight no longer needing him.
Except in the episode "Secrets of My Excess", however this time, Spike is transformed into a gargantuan rampaging beast that almost completely demolishes Ponyville. Even then he may lean into this since it's all for the sake of hoarding "gifts".
Most of the Rogues Gallery for the show act as this or mere petty bullies. The foes used in the two part specials are the only notable exceptions, and even then their detrimental arrogance and the often humiliating manner they are taken out almost makes you pity them.
On the other hand, his alternate-universe counterpart, with just onemorehumiliation during the Trauma Conga Line that was his childhood, was a genuine threat and not sympathetic at all.
The wolves Huff and Puff from Piggsburg Pigs. They're always trying to catch and eat the main characters, but they're nothing compared to all the swamp monsters, demons, and undead beasties lurking in the Forbidden Zone outside town.
Leonard McLeish from The Hub's Pound Puppies series. He's self-centered, short-tempered, and clearly more concerned with impressing people and getting promoted than actually doing his job as head dog catcher, but he's not really a bad guy.
In one of the early World Premiere Toon shorts, the Girls actually commit a bank robbery solely to show the Boys how it's done. When the Girls are brought in for the crime, the boys turn themselves in, in an attempt to appear "big time".
In another, during the actual series, the Boys stumble upon Mojo Jojo's Deathtrap plans, and they, along with the Girls, mistake it for a "scavenger hunt" — so they find all the things it calls for and put it together, and once it's assembled, the Girls think it's a theme-park ride, so they willingly submit to the plan intended to destroy them.
In another episode, the Boys catch a cold while loitering on the grass in yet another attempt at crime. Even though they end up unwittingly mutating the cold into a deadly strain of virus and even more unwittingly starting an epidemic in Townsville, the viewers still can't help but feel sorry for them.
And in another episode, they manage to actually succeed at stealing an orange, for once, and when it splits apart, are reminded that, as amoebae, they are capable of multiplying. There is quickly an army of them, and the only thing they can think to do is to steal all the oranges in Townsville (although this does cause the citizens to contract scurvy).
The Gangreen Gang can also qualify as this. While they're not anywhere near as incompetent as the Amoeba Boys, it's pretty hard to take them seriously as actual villains since their crimes are really based on typical bullying, prank calling, vandalism, etc. In fact, in the episode "Aspirations", the girls couldn't even take them seriously as a criminal element and called them nuisances. It also doesn't help that they're teenagers, making them younger than most of the other villains the three superheroes fought.
Hack and Slash, the bumbling minions of Megabyte, in ReBoot. In fact, they are justified in being bad guys by the fact that the heroes always stop them before they could do anything really awful. When the heroes fail to arrive to stop them from killing a traitor to Megabyte, they let him go off on their own and undergo a Heel–Face Turn.
Pretty much the entireRescue Rangers rogues gallery is quite harmless. And probably the whole reason that only a bunch of rodents are even bothered to take the time to deal with them. Case in point: inventing a self-propelled walking laser cannon capable of cutting up a glacier, (those things aren't exactly "just" a big ice cube) and only using it to warm up a giant vat of jello used to create an earthquake machine to break open a gold depository. Instead of, y'know, blasting your way in with said self-propelled walking laser cannon.
In the The Simpsons, Sideshow Bob also frequently veers into this territory. The poor guy can't even win against a rake.
Gargamel in The Smurfs (and pretty much most Smurfs villains except Balthazar).
Dr. Ivo Robotnik and his henchmen from Adventures of Sonic the Hedgehog. While Robotnik often tries to do something rrrrotten, he ALWAYS fails horribly, and Sonic torments the doctor so sadistically, that it becomes hard to sympathize with the heroes. He makes incredibly inept robots, repeatedly has crying fits, and is sometimes too distracted with himself to notice that his plan isn't working.
Note that in the Sonic SatAM series that was aired around the same time, Robotnik is...very much not harmless. At all. Snively though is a reedy and sneering little man who is always consumed by his Uncle Robotnik's quite massive shadow. Also, he's a baldy. However, he turns out to be a Not-So-Harmless Villain when he manages to slip out before his uncle is killed, and return as a The End... Or Is It? cliffhanger for a season that we will never receive.
Nope, he was still going to retain this role. In one interview with screen-writer Ben Hurst regarding the third season that never arrived, it was revealed that Snively was going to take a shot at becoming the new Big Bad, only to be shortly upstaged by Ixis Naugus, and would later make a Heel–Face Turn and join the Freedom Fighters.
Dr. Eggman on Sonic Boom takes this trope and runs with it, to the point where Amy actually pities him., now being a villain who is Affably Evil and has civil interactions with Sonic and company when they're not fighting, every other episode he's in an Enemy Mine situation with them, and he now has his Card-Carrying Villain tendencies exaggerated. Similar to his Adventures of Sonic counterpart, he does almost outwit Sonic on a few occasions though, keeping him Not So Harmless.
Sandman in The Spectacular Spider-Man can never quite get his big score. Before his superpowers, Spider-man jokes about how many times he's been caught. After, he can actually fight Spidey, but then proceeds to forget or be unable to keep his take when he escapes down the drain. He also gets a couple of Pet the Dog moments when it's revealed that while he cares a lot about the Big Score, he doesn't really want to hurt anybody (other than Spider-man, of course).
Plankton from SpongeBob SquarePants. After a while, you just start to feel sorry for the guy, especially when compared to how heinous Mr. Krabs' actions to get more money have become. It's more prominent in the post-movie episodes, where he could easily be one of the Trix Rabbit's drinking buddies. Granted, he gets a Not-So-Harmless Villain moment in the movie, but still...
Most of the time, it seems that he just wants some manner of success. In the cruel Yank the Dog's Chain episode "Plankton's Regular", after getting just one regular customer, he immediately stops trying to steal the Krabby Patty secret formula. Mr Krabs and Spongebob still found it necessary to "thwart" him.
Until they start gunning down unarmed pacifist, cracking open escape pods so the helpless people on board will die in space, and Zerg Rushing that is.
Steven Universe: Despite her first few appearances striking absolute horror into the Crystal Gems, Peridot seems to amount to this, being not much of a match for the Crystal Gems even with substantial technological advantages- and without anything to hide behind, all of her revealed abilities are mostly there to help her run away. She also has the attitude of a high-strung desk worker more than a potentially world-destroying supervillain, which makes even her moments of Not-So-Harmless Villain harder to take seriously.
There's also the Ruby Squad, who really, really aren't cut out for enforcers of Homeworld's fascist regime. They're small, adorable, not that bright, and in over their heads.
Bull Gator and Axl in Taz-Mania. In the very meta episode "Retakes Not Included", Bull even observes that they are what passes for villains on the show.
In the original cartoon, Arch-Enemy Shredder was many times this, particularly in later crossover after the initial story arc of the first season. Only in that one though; the other media tends to show him as a real threat.Turtles Forever.
Control Freak from Teen Titans. Despite being able to animate the inanimate to do his bidding and inadvertently altering television frequencies to literally rot people's brains, he STILL didn't get on the Titans' list of main villains.
Control Freak:The Puppet King?! They fought him ONCE!!
Tom, from Tom and Jerry, was so ineffectual and sympathetic that, in many cartoons, one failed to see how Jerry was even a victim. Particularly egregious examples, in fact, would cite that he wanted nothing more than to leave Jerry in peace, and Jerry could not stop antagonizing him and trying to ruin his life. Often, the shows started with Jerry trying to steal Tom's milk, break into a safe/refrigerator/ship that Tom was guarding or just being a dick in general. Granted, sometimes Tom's methods can get a bit extreme, he's just trying to protect his property or doing his job.
Ditto for Sky-Byte and his Team Rocket in Transformers: Robots in Disguise. Except that Sky-Byte would actually be leadership material if only a few things were different. It's just that he lacked the only two qualities that really mattered for a leader: aptitude and intelligence.
On Ugly Americans, there was Twayne Boneraper, a demon who has only managed to claim one soul his entire career, that of a sick cat. His crowning moment of incompetence came when he ensures an utterly incompetent and unelectable politician to become mayor in return for his soul. It's such an Epic Fail that he winds up in an infernal court, accused of not worthy of being a demon. (Although, as Laughably Evil as he is he did murder all seven of his brothers, one of whom was the general of Hell's army, so he may have a darker nature underneath than his behavior suggests.)
Most of them are of the Not-So-Harmless Villain type. It's shown that the reason OSI and such tolerate the supervillains' stupid games is that it keeps them from committing real crimes or blowing up cities. (Those who don't play the game have to deal with SPHINX.) The Monarch, in particular, is a special case. When he was taken off of Dr. Venture, he was unhappy with the normal game and proceeded to kill 5 heroes in a short time.
Doctor Mrs. The Monarch is the most competent villain and, quite possibly, the most competent character on the entire show. Even the Sovereign of the Guild respects her.
Doctor Killinger's entire reason to exist seems to be to snap out villains from this trope and into Not-So-Harmless Villain instead.
Doctor Killinger's fourth episode, The Doctor is Sin, makes a pretty persuasive argument that Rusty Venture himself is this. Killinger spends much of the episode giving Venture Industries "efficiency" training, with the true aim of turning Doctor Venture into a real, Guild-bonded supervilain.
Wacky Races Dick Dastardly. It wasn't for nothing that he had a whole trope named after him.Nobody really takes him seriously. He couldn't beat himself in solitaire even if he cheated.
Odlaw in the animated series Where's Waldo? (Where's Wally?). As so many bad things keep happening to him in the name of comedy, and all he ever wants is to commit a single act of theft, you have to feel for the guy. Also, his determination is admirable!
From Yin Yang Yo!, Carl. The commercials for the next episode suggest he'll join the heroes so he can keep up with everyone else.
X-Men: Evolution: Toad and the rest of the Brotherhood, at least by Season two. At first, they were at least even with the X-Men, and were able to over power them in one episode, except for Toad. But slowly, each one got more and more Pathetic. Pietro became more cowardly, Blob became more dumb, and Avalanche went through massive character Derailment. In season 3, they were bested by only Two X-Men, one being the weakest member. It was why the Acolytes were introduced, who were definately not this.
Usual, given that this is the reason why they're so popular, with people playing up the ineffectual sympathetic part, and ignoring the vilain part.
This is reinforced by Jack being probably the only fictional character, let alone villain, to have a breakdown failing to interrogate a parrot that simply repeated everything he said.
The problem is that Jack is 'trying' to be a villain yet is fairly bad at it. When he turned to good for a while before returning to evil, it wasn't that he was planning to betray them from the start, he 'did' try to be good but was afraid he would fail at being good just like he failed at being evil.
