Arch-Enemy: The Toad Air Marshal sees himself as Bucky's, though really Bucky and Toadborg are a closer fit.
Adaptation Distillation: First a comic book, then the cartoon, then one video game, and finally a second one meant to end the series.
A.I. Is a Crapshoot: The main villain, Komplex, is a sentient computer program that the toads designed to run their planet. Naturally it turned evil, brainwashed them, and sent them on the warpath. All for no readily apparent reason other than "AI is evil." Even the benevolent android Blinky is reprogrammed by Toadborg in one episode to sabotage the ship, but Bucky and the gang keep him on anyway. Blinky's central programming fought back against Toadborg's control and actually managed to break free.
Awesome, but Impractical: The toy version of the Toad Croaker. While in the show, games, and comic it was presented as more or less a one man recon vehicle, the toy was altered slightly to look like a left shoe, complete with treads on its bottom. The reason was so that kids would use it to smash it down onto Toad Trooper action figures, "stepping" on them... Needless to say the toads' own Double Bubble didn't come anywhere close to this level of awesome.
This kicks off the revelation of the Batman Gambit in "The Taking of Pilot Jenny" when, with the Righteous Crew seemingly at the mercy of K.O.M.P.L.E.X. and Toadborg, the ship they're all in is rocked by gunfire as the Indefatigable cuts through their stagnate defenses like a hot knife through butter.
Another one occurs in "Bye Bye Berserker Baboon." The Terror Toad, a monstrous amphibian warrior, has the heroes cornered. To make matters worse, unlike his brethren, he is not afraid of Berserker Baboons and looks like he could eat them like popcorn. Bucky O'Hare, injured in a failed attack on the monster, suddenly dives down and burrows through the ground away, escaping. Unable to believe they've been abandoned by their leader, the others are treated to the sight of their ship suddenly launching and flying away. The monster gets closer and closer as the Air Marshal cackles that he's finally beaten even the "Great Bucky O'Hare." Suddenly, the sound of rockets firing is heard and Bucky returns on the Toad Croaker. Turns out he just went out to the next planet over to snag several jars of the Aniverse's best tasting flies, with which he proceeds to lure the Terror Toad back to the Toad Mothership where it proceeds to tear the place apart.
Camp Gay: Captain Smada. The scary part is this may be unintentional.
Canon Foreigner: Bruiser, Commander Dogstar, Mimi LaFloo, Toadborg, Frix and Frax, and Al Negator from the cartoon.
Cat Folk: Jenny and the residents of her home planet Aldebaran.
Chekhov's Gun: Actually, Willy's water gun, which is "confiscated" (read pilfered) by Deadeye in the second episode. It becomes VERY important to the crew when they're making their escape from the Toad Mothership. It's lampshaded later when the same tactic doesn't work a second time.
Child Prodigy: If Willy were not one of these, it's doubtful the show would have gotten past the first episode.
Cool Ship: At least Bucky's ship's name is easily the coolest in Western TV animation, the Righteous Indignation.
Curb-Stomp Battle: When Jenny tried to use her psychic powers to defeat Toadborg, she quickly learned the hard way that machines aren't nearly as susceptible to her abilities as those who are completely organic.
Darker and Edgier: The webseries continuing this show most definitely dove into this area, for the better some would say.
The cartoon was only slightly darker than the comics, the characters (especially Bucky himself) are far less silly and the Toads are treated as an actual threat. They even manage to enslave the inhabitants of Bucky's homeworld, Warren.
Day in the Limelight: After "War of the Warts" every crew member of the Righteous Indignation got a least one episode in which to shine, sometimes two.
Drill Sergeant Nasty: Bruiser falls into the role (or at least a kid-friendly version of it) quite easily, when he is a guest instructor at the Betelgeusian military academy. His mother is very proud of him.
Early-Installment Weirdness: In the first three episodes, Frix and Frax have deep, gruff voices that actually make them sound somewhat tough. This is sharp contrast to all their other appearances where they have high, squeaky, whiny voices.
The Lancer: Deadeye and Jenny share this slot, with Jenny being the Number One and Bucky's closest co-worker, and Deadeye being the more shady and pragmatic foil to Bucky's clean-cut front-page heroism.
Friend or Idol Decision: Toadborg wants the defense codes or he'll jettison Bucky, Jenny and Deadeye into space. Willy faces a moral dilemma. Does he destroy the disks containing the codes, or give them up to save his friends? At Bucky's insistence he smashes them, to Toadborg's fury.... until Al Negator turns up with a copy of the codes. Oops.
From Nobody to Nightmare: Before Komplex corrupted them, the toads were a lazy, decadent race with a penchant for shoddily-made consumer products.
Gaia's Vengeance: Subverted. The toads have a machine which can completely change the climate and ecology of a conquered planet into a swamp. Given what we see of the cities on such converted worlds, this cannot be a pleasant experience for anything currently on the surface when this happens.
Holding Out for a Hero: The enslaved hares put to work building a new climate converter are waiting to be rescued by Bucky O'Hare, which irritates Mimi LaFloo who is trying to organize a resistance movement to free themselves.
Ineffectual Sympathetic Villain: The Toad Air Marshal. He sees himself as Bucky's arch-nemesis but Bucky seems to view him as little more than an annoyance.
Improbable Aiming Skills: And with a flying disk no less. Also some of the shots Deadeye pulls off seem fairly unlikely even given his background.
Informed Ability: The Toad Air Marshal is forever talking about his accomplishments and skills, but for the run of the series he's much more of joke character than anything else. Of course, considering the only guy in the entire Empire who seems remotely competent is in a higher position than him and above that is a super-computer, maybe he really is the best Komplex could get for the job.
No Problem With Licensed Games: The tie-in NES game was popular among many of those who played it. The arcade game, which allows Bucky to defeat the toads once and for all, is without a doubt awesome.
Not-So-Harmless Villain: According to Blinky, the reason the Toads' initial push was so unprepared for was that everyone thought they were completely harmlessnote Which they were...at first.... Silly Mammals.
Not Quite Dead: In the cartoon, Bruce gets zapped by the photon accelerator and everyone thinks he's dead (or rather, had "attained oneness with the Aniverse") as a result. He actually got teleported across the Aniverse. In the comic, however, Bruce actually had attained oneness with the Aniverse.
Oblivious to Love: Jenny and Mimi LaFloo are quite obviously attracted to Bucky but, based on his reactions to their advances, this would probably be news to him. Somewhat justified as the former has a policy of secrecy about her, while the latter spent the better part of her introductory episode expounding on how little she liked Bucky. That he was in disguise when she said this doesn't seem to register.
The Obi-Wan: Bucky actually has one in the form of the mysterious Mentor, a rabbit who taught him how to be a warrior. Given how young he's portrayed as, one wonders when he had time to do that AND go through the Academy on Genus.
Oh Crap: Nearly all the toads are terrified of Berzerker Baboons and they have this reaction whenever one shows up.
Reformed Criminal: Deadeye straddles the line between this and Recruiting the Criminal. He used to be a member of the notorious pirate band the Corsair Canards, but seems to have left on good terms. He is well-known and respected among the Corsairs (though some consider him a sell-out) and keeps in touch with his old shipmates. He is also gunnery chief on the Righteous Indignation and a loyal and trustworthy member of Bucky's crew.
Reptiles Are Abhorrent: Al Negator is a two-timing scuzzball only out for profit, willing even to betray the toads. Likewise, Samurai lizard Sly Leezard is quite the bastard. Note that this is subverted when Sly's boss, the supreme commander of the Samurai lizards, has him punished for breaking the Samurai's code of honor, and lets the heroes go free (so long as they never return).
Restraining Bolt: K.O.M.P.L.E.X. had at least one programmed into him, he cannot hurt his designers, so when he took over the toads, he sent them into deep space.
Scott McNeil: Deadeye Duck and various other characters, it's one of his early gigs.
Secret Keeper: Willy regarding Jenny. In point of fact he gets let in on a number of secrets from all the crew over the course of the series.
Sufficiently Advanced Alien: Encountered in the comic book in the form of a white mouse. Apparently anything he creates that travels outside his "sphere of influence" ceases to be, which the toads found out to their detriment when the magma they stole from his planet disappeared when they got far enough away. He proved to be something of a benevolent version of this trope, using his powers to rescue the toads on the ship (though he later admitted the place he'd sent them to was known for its high property taxes).
While the toads that recklessly fly into the Deadeye's general area might count, they're Brainwashed and Crazy as an excuse. The United Animal Security Council, on the other hand, seems almost actively trying to get wiped out by the Toad Empire.
The Twindividual Frix and Frax. They're only distinguishable from one another due to the Frix's larger chin and jawline compared to Frax. Otherwise they're essentially identically and never appear separately.
Zerg Rush: The toad soldiers have training and hardware that's usually shown as being inferior to what Bucky's crew and lone ship can bring to bear in a fight. The main reason they're still dangerous is they're the only side to have an actual fleet and armies. To keep the amphibian menace from engulfing the Aniverse, by the end of the show SPACE has managed to assemble a grand total of three ships, each with a crew of about six members.
