- Debut: Bowser's Mushroom Factory
The hero of the Mushroom Kingdom, who defends the Mushroom Kingdom from Bowser and constantly rescues Princess Peach from his clutches.
Tropes associated with Mario:
- Baleful Polymorph: He gets turned into a Goomba for most of Mario's Unexpected Transformation.
- Big Damn Heroes: He rescues Luigi in Luigi the Prankster.
- Distressed Dude: In Luigi's Quest, Part 5 of Mario's Quest, and Peach's Quest.
- Genre Savvy / We Are Not Going Through That Again: At the end of A Day in the Life of Mario. Tired of having to rescue the princess from Bowser again and again, he builds a giant wall in front of her castle to prevent Bowser from kidnapping her again.
- Heroic Mime: Not too surprisingly, Goomzilla doesn't give him a voice.
- I Want My Beloved to Be Happy: Despite his fears that Peach will not love him anymore as a Goomba in Mario's Unexpected Transformation, he still goes to save her anyway. Thankfully, she still does.
- No Hero Discount: Despite his heroic deeds, he still receives bills, as we've seen in Bowser's Mushroom Factory.
- Out of Focus: Somewhat. Mario is still the hero of the Mushroom Kingdom, but with the exceptions of A Day in the Life of Mario, Mario's Quest, and Mario's Unexpected Transformation, most of Goomzilla's other videos put his friends—and sometimes his enemies—in the spotlight, while he either gets himself captured or his own antics aren't in the focus as much.
- Revenge Before Reason: This version of Mario seems to have a "shoot first, ask questions later" mindset, at least in Mario's Quest, where he was ready to attack both Professor Kolorado and Goomfrey until he is assured that they're good guys.
- Surrounded by Idiots: While trying to blend in with the other Goombas in Mario's Unexpected Transformation, Mario is forced to tolerate their idiocy as they can't pass their IQ test to save their lives. He also finds it hard to believe that Bowser would just buy the Microgoomba's story about how he supposedly offed Mario, and medal him just like that.
- This Is Gonna Suck: During one of Luigi's pranks in Luigi the Prankster, Mario quietly watches and can only sigh, knowing what he's doing and that it won't end well.
- Debut: Bowser's Mushroom Factory
Mario's younger brother who helps him in his adventures. He is often the target of the slapstick in Goomzilla's series, and noticeably has a bit of a mischief streak.
Tropes associated with Luigi:
- Bindle Stick: Carries one in Luigi's Quest.
- Butt-Monkey: He gets his share of bad luck for most of Goomzilla's series. Averted in Luigi's Quest, his big starring movie role.
- A Day in the Limelight: Luigi the Prankster and Luigi's Quest focus on him. So does Part 5 of Mario's Quest, to a lesser extent.
- Distressed Dude: In Luigi the Prankster, Part 3 of Mario's Quest, Yoshi and the Lost Egg, and Peach's Quest.
- Heroic Mime: Goomzilla doesn't provide a voice for him.
- It Amused Me: Why does Luigi suddenly feel like pranking people in Luigi the Prankster? We don't know. He just does.
- Jerkass Ball:
- He gets hit with this in Luigi the Prankster, playing rather mean-spirited pranks on people he wish he hadn't, such as when he set up a wire to trip Bowser shortly after recovering from the loss of his Mushroom Factory, or tempting a piece of chicken in front of a hungry Wario's face.
- There's also Luigi's Spooky Ghost Spooky Quest. After getting turned into a ghost, Luigi uses his spectral form to cause more mischief, including stealing people's foods and watching a Goomba take a shower. Good thing the trailer for it was just an April Fool's video.
- The Lancer: To Mario.
- Late to the Tragedy: It was because Luigi hasn't attended Peach's Castle with Mario that he avoids Kamek's kidnapping of his friends in Luigi's Quest. Doubles as Slept Through the Apocalypse since he was in bed as well.
- My God, What Have I Done?: He and Captain Toad feel really guilty for accidentally breaking Francis' Lady Bow poster in Luigi's Quest.
- Naked People Are Funny: Giant Pantsless Luigi. Enough said.
- The Prankster: In Luigi the Prankster.
- Wholesome Crossdresser: At one point in Luigi's Quest, he disguises himself as a woman to trick Francis into giving up his Energy Cell.
- Debut: Bowser's Mushroom Factory note
The princess of the Mushroom Kingdom. She is often kidnapped by Bowser, but Mario is always there to help her.
Tropes associated with Peach:
- Absentee Actor: She doesn't appear in Wario the Bankrupt or Yoshi and the Lost Egg, although she is mentioned at least twice in the latter.
- Big Damn Heroes: She helps Mario get back to normal in Mario's Unexpected Transformation.
- Brainwashed and Crazy: Under hypnosis, she attacks Luigi in Luigi's Quest.
- Damsel in Distress: As usual.
- A Day in the Limelight: She's the star of Peach's Quest.
- Genre Savvy: Peach seems to have a gift of seeing through people's disguises. In Bowser Needs Minions, she sees through a Goomba's Toad disguise and shoos him away with only a banana, so she wouldn't be kidnapped or have to work for Bowser. And in Mario's Unexpected Transformation, she recognizes Mario's Goomba form, despite Mario's fears that she wouldn't. This also makes her a total contrast to Bowser, who was easily fooled by Goomba disguises and forms at least twice.
- Heroic Mime: An unusual example, since Peach has been shown to be perfectly capable of speaking in the games.
- Heroic Willpower: It appears she was still trying to fight her hypnosis in Luigi's Quest, as she tries to break Mario out of his cage. But with Kamek seeing this as "enthusiasm to absorb his power", it's hard to tell for sure. Later comes in full circle when Luigi manages to remind her of how much Mario means to her.
- Hypnotize the Princess: In Luigi's Quest, Bowser decides that this is the best way to make her loyal to him after she almost rescues Mario with the power she's gotten from him.
- Moral Dissonance:
- Quite a bit of commentors found it odd how, when Peach is taken to her captive room in Mario's Quest, she says "Splendid!", though it might be because she just likes how the room looks.
- She also looks at Bowser's diary later in the movie, which realistically is a blatant violation of his privacy, though that still doesn't excuse him from beating her.
- Perpetual Smiler: It's hard to tell at first glance, but a closeup shot in the beginning of Peach's Quest shows that this Peach plush is indeed smiling at all times.
- Sympathy for the Devil:
- She was quite shocked when Bowser makes Koopa disappear in Bowser and the Koopas' Staff.
- She comforts Bowser when he's powerless in Peach's Quest. This isn't the first instance of her showing kindness to her enemies in this movie either.
- Textile Work Is Feminine: Peach was shown sewing during her kidnapping in Mario's Quest. We later find out this was used for a disguise.
- Throw the Dog a Bone: She doesn't get kidnapped in Luigi the Prankster and Bowser Needs Minions.
- Voice of the Legion: She gains a distorted voice when she's hypnotized in Luigi's Quest. Lampshaded by Bowser.Bowser: I can ignore the change in your voice with treatment like this.
- Yank the Dog's Chain: She actually gets hit with this TWICE in Luigi's Quest.
- After receiving some of Mario's power, she almost succeeds in using it to rescue him...but then Bowser shows up at the last second to stop her, then later has her hypnotized so she won't try that again.
- Near the end, Luigi and Peach go to restore Mario his power...but then Solus takes all of Mario's power from Peach at the last minute, weakening her. This was moments after getting un-hypnotized. Good lord, Goomzilla, how much does this poor girl have to go through?
- Debut: Bowser's Mushroom Factory note
Mushroom citizens that serve the princess, when they don't have an occupation for another part of the Mushroom Kingdom.
Tropes associated with Toads:
- Cold-Blooded Torture: That poor innkeeper Toad has been kidnapped and tortured into telling Bowser how to repair the broken generator in Mario's Quest.
- The Dog Bites Back: The innkeeper Toad manages to fight back against the Goomba that whipped him earlier.Innkeeper Toad: Pesky things...
- The Lancer: Captain Toad is one to Luigi in Luigi's Quest, and a regular Toad is one to Peach in Peach's Quest. Subverted in the latter case, where it was really a Duplighost luring her into a trap.
- New Job as the Plot Demands: A variation. We've seen some Toads working for the princess, one Toad driving a train (with Toadette as the chef), an innkeeper Toad, a police chief Toad, and a Toad hosting a carnival.
- Perpetual Smiler: All of the Toads have a bright smile on their face—which they keep even when something bad is happening to them.
- The Smurfette Principle: Toadette, the only character (so far) that Goomzilla's sister has provided a voice for.
- Debut: Bowser's Mushroom Factory
A friendly green dinosaur who occasionally aids the Mario Brothers in their adventures, up to and including letting people ride on his back.
Tropes associated with Yoshi:
- Big Damn Heroes: In Mario's Quest. Yoshi trying to protect a star from a falling pyramid resulted in him getting crushed. But the star kept him alive and immune to Bowser's generator that turns people to stone. Now out of the pyramid and fully conscious, Yoshi rockets his way up to Bowser's castle, defeats Bowser, and reverses the effects of the generator.
- Cold-Blooded Torture: While being held tied up by Bowser and his minions in Luigi's Quest, Yoshi sees a delicious cake in front of him, but he's too far away from it to eat it.
- A Day in the Limelight: He's the star of Yoshi and the Lost Egg.
- Disney Death: He supposedly got killed by a falling pyramid in Mario's Quest. He did, but it doesn't stick.
- FaceHeel Turn: The worst ending of Yoshi and the Lost Egg has him do this. He swears allegiance to Wario and Waluigi and betrays the Mario Bros. by tricking them into enslavement by them. What's even worse is that the cheerful voice clips Goomzilla played for Yoshi while this was going on indicated that he LIKED it!
- Heroic Mime: Justified, as he's a dinosaur.
- Out of Character: Let's be honest, Yoshi selling out the Mario Brothers in the worst ending of Yoshi and the Lost Egg was pretty out-of-character of him, and some people felt like it came out of nowhere. Goomzilla himself even admits this.
- Powerup Mount: He will occasionally let people ride on his back, just like in the games.
An archaeologist who longs for adventure.
Tropes associated with Kolorado:
- Adventurer Archaeologist: Straight-up says he's one.
- The Bus Came Back: He returns in Peach's Quest after being absent from Luigi's Quest.
- Palette Swap: He's just a Koopa Troopa plush with a mustache and fedora hat.
- Red Herring: He was originally thought to be the person who stole the Book of Delopp, but this turns out to be false.
- Shout-Out: He once compared himself to Sherlock Holmes.
The main antagonist of the series, who constantly wreaks havoc on the Mushroom Kingdom and kidnaps Princess Peach to try and win her heart.
Tropes associated with Bowser:
- Aesop Amnesia: Bowser learned to treat his minions better in Bowser and the Koopas' Staff, and then re-learned in Luigi's Quest.
- Ahem: His fist line in Goomzilla's series.
- And Now You Must Marry Me: His initial plan for Peach in Peach's Quest.
- Assumed Win: In Mario's Unexpected Transformation, after a Microgoomba claimed to have given Mario a "game over" by running into him, he promotes him to Goomba Commander, without even bothering to send someone to check for the body, or give him time to be reported missing, or anything. Even Goomba!Mario can't help but shake his head as Bowser eats it up.
- Bad Boss: This version of him leans more into this territory, whereas his game counterpart was somewhat of a more Benevolent Boss. He was power-hungry enough to ignore his minions and even do away with them in Bowser and the Koopas' Staff, and didn't care about his minions getting turned to stone in Mario's Quest. And that's not even getting into what happened to Solus...
- Big Bad: As you would expect, he's the primary antagonist of most of Goomzilla's videos, particularly Mario's Quest. He starts off as the big bad of Bowser and the Koopas' Staff, Luigi's Quest, and Peach's Quest, but he gets tossed aside in favor of various other villains.
- Disney Villain Death: In Mario's Quest. It's really more of a Disney Villain Defeat since it doesn't kill him, but still.
- Disproportionate Retribution: Peach looking at his diary doesn't excuse him from having her beaten senseless in Mario's Quest.
- Enemy Mine: Is forced to work with Peach in Peach's Quest.
- Evil Brit: Technically this, since Goomzilla, who lives in the UK, provides his voice.
- Evil Sounds Deep: Goomzilla makes his voice deeper when voicing for Bowser, most likely through alterations. This especially becomes noticeable after hearing his narration for Luigi's Spooky Ghost Spooky Quest.
- Faux Affably Evil: While most incarnations of Bowser portray him as a jerkish brute, Goomzilla's version of him at least tries to appear as a civil person.
- Genre Savvy: Has some shades of this, especially in Luigi's Quest. When Peach tries to use the power she gained from Mario to rescue him, Bowser sees through this before she can and, to make sure she doesn't try that again, takes her to a hypnotist to make her loyal to him, something most Mario fans feel he should have done a long time ago.
- Hidden Depths: Bowser likes fishing. Who knew?
- Idiot Ball: He's smart enough to build a star-powered generator, yet fails to recognize people disguised as or transformed into Goombas.
- Knight of Cerebus: Mario's Quest portrays his sinister plans in a more serious light.
- Laughably Evil: You have to admit, Bowser looks pretty hilarious in his fisherman outfit.
- Near-Villain Victory: In Mario's Quest. He manages to turn everyone except himself and Peach into stone so that they can be the only two people alive. Had it not been for Yoshi and the power of the stars, it would have kept. Not even Solus was as ballsy as to basically kill everyone.
- Not Me This Time: Out of all the suspects in Yoshi and the Lost Egg, Bowser is the only one who did not interfere with the Yoshis in any way. In fact, the route to the best ending requires that you stay as far away from Bowser's Castle as possible, period.
- Pre-Asskicking One-Liner: Before the final battle in Mario's Quest."You have three minutes to entertain me before your body is frozen forever."
- Suddenly Voiced: It wasn't until Mario's Quest that Goomzilla gave Bowser an actual voice. Prior, he only used his sound effects from the games. Justified, as Goomzilla says himself that he uses voices for complicated matters, such as Bowser's nefarious plots that don't involve just kidnapping the princess.
- Villain Has a Point: In Mario's Quest. While Peach looking at his diary isn't an excuse to beat her, she would arguably be violating a privacy law or two in real life.
- Villainous BSoD: Bowser feels truly beaten once everything has been taken from him at the beginning of Peach's Quest.Bowser: Ugh...it's over, Peach. They took over my castle...they took all of my minions...they made me small as a Goomba!
- Villainous Crush: On Peach, obviously.
- Villainous Rescue: Attempts one for Peach in Peach's Quest when she's cornered by two Duplighosts. It fails massively.
- What Happened to the Mouse?: By the end of Luigi's Quest, Bowser's reaction to the heroes getting rid of the Diode, as well as un-hypnotizing Peach, is not shown.
- Would Hit a Girl: He orders Goomfrey to beat Peach with a baseball bat for looking at his diary in Mario's Quest.
- You Know What to Do: Says this to the mushroom hypnotist that puts Peach under Bowser's control in Luigi's Quest.
- Debut: Bowser's Mushroom Factory
Bowser's #1 minion.
Tropes associated with Koopa:
- Absentee Actor: He doesn't appear in Yoshi and the Lost Egg.
- Adorable Evil Minion: You have to admit, he's pretty cute and cuddly for Bowser's #1 minion.
- Affably Evil: Really, working for Bowser is the only thing that makes him evil. He's not really a bad guy outside of that.
- Bouncer: Serves this role in Mario's Unexpected Transformation.
- A Day in the Limelight: He gets more focus in Bowser and the Koopas' Staff and, to a lesser extent, Luigi's Quest.
- The Dragon: Before Kamek came along, Koopa normally acted as the second-in-command to Bowser. He appears to have reclaimed this position when Kamek has been left powerless in Luigi's Quest.
- Easily Forgiven: Koopa was rather quick to forgive Bowser for basically killing him in Bowser and the Koopas' Staff.
- Enemy Mine: In both Bowser and the Koopas' Staff and Luigi's Quest, he teams up with the heroes to stop a common enemy.
- Et Tu, Brute?: How he felt when Bowser tossed him aside in Bowser and the Koopas' Staff.
- Genre Savvy: In Luigi's Quest. He manages to successfully follow Luigi to Rogueport, and would have succeeded in capturing him too had it not been for the trapdoor he fell in. Then, when that doesn't work, he puts a tracking chip onto Captain Toad's back to give Luigi away. And when Yoshi was on his tail, he fights him off until they get to the Diode, where he takes Yoshi's energy.
- Hypercompetent Sidekick: He's often smarter and more rational than the brute he works for.
- The Starscream: Briefly becomes this in Bowser and the Koopas' Staff. It doesn't end well.
- Undying Loyalty: Almost destroyed in Bowser and the Koopas' Staff when Bowser goes power-hungry enough to ignore Koopa.
- Debut: Bowser's Mushroom Factory
Underlings of Bowser with an unfortunate tendency of getting stepped on.
Tropes associated with Goombas:
- Absentee Actor: We don't see any Goombas in A Day in the Life of Mario.
- The Goomba: Naturally.
- Invisible Anatomy: Despite having no arms, these Goombas are shown to pick things up just fine.
- Mini Mook: A Micro-Goomba shows up from time to time in Goomzilla's videos.
- Paper-Thin Disguise: One Goomba posed himself as a Toad to try to get some other Toads to join Bowser in Bowser Needs Minions. Keyword being try.
- Perpetual Frowner: All Goomba plushes, custom-made or store-bought, are stuck with that same grumpy frown. In all fairness, though, it's rare you see an actual Goomba smile.
- Those Two Bad Guys: Goomzilla likes to pair a Micro-goomba with a regular Goomba in a few of his videos, to the point where he gives them the title of "The Goomba Bros." in the outtakes for Yoshi and the Lost Egg.
- Took a Level in Badass: Goombas in earlier videos were fairly as weak as they always are. But in Mario's Quest, they were a bit more of a hindrance towards Mario and Luigi. There's also the magical Spiked Paragoomba that manages to turn Mario into a Goomba in Mario's Unexpected Transformation, seemingly to torment him.
- What Happened to the Mouse?: There's a Spiked Paragoomba that's absorbed all of Kamek's magic in Luigi's Quest. He completely disappears from the rest of the story, his new powers difficult to control. Come Mario's Unexpected Transformation, this Goomba shows to be in perfect control of his powers—and decides to torment Mario a little with them.
Wario & Waluigi
- Debut: Luigi the Prankster (Wario), Bowser Needs Minions (Waluigi)
Two greedy brothers (possibly) who would do anything to make a quick buck—even evil things.
Tropes associated with Wario & Waluigi:
- Bad Cop/Incompetent Cop: In Wario the Bankrupt. Although they caught the crook that stole the Shy Guy's TV, they watched said TV instead of arresting the crook, which lead to him getting away, and the two getting fired for their incompetence.Wario: I hate you.
- The Bad Guy Wins: The Anarchist's Ending from Yoshi and the Lost Egg in a nutshell.
- Big Bad Duumvirate: Of Yoshi and the Lost Egg. They didn't lay a finger on the lost egg, but they did kidnap Birdo's baby to force it to make eggs for them.
- Big Eater: At least Wario is, if Luigi the Prankster is of any indication.
- A Day in the Limelight / Villain Episode: Wario the Bankrupt focuses on them.
- Fartillery: Wario uses this to knock out the heroes in Mario's Quest.
- Here We Go Again!: In Wario the Bankrupt, it looks like they made enough money to pay off their bills. But then they get another bill for the damages they caused, putting them back to square one.
- Hero with an F in Good: Wario in A Day in the Life of Mario.
- Honor Among Thieves: Despite being scoundrels, they have each others' backs. This is best exemplified in "Bowser Needs Minions!", where, when escaping from Bowser's wrath, Waluigi chooses to stay by the stairs and wait for Wario to escape with him, instead of just leaving him behind.
- Jerkass: Just like their game counterparts.
- Karma Houdini: Played with in Yoshi and the Lost Egg. After Birdo defeats them and reunites with her baby, you have the option to punish them for their misdeeds or telling Birdo about the lost egg. The latter option is just a click away to the best ending, indicating that returning the lost egg was more important than disciplining Wario and Waluigi. By giving them Laser-Guided Karma through picking the other ending, you're just making the other Yoshis wait for an egg that will never come. That being said, Birdo does give them a good butt-whooping either way.
- Only in It for the Money: The only reason they join Bowser's army in Bowser Needs Minions was so they could get the moneybag that Bowser was keeping. Then, come Mario's Quest, they quickly took the moneybag and tried to escape Bowser's castle with it, but Bowser eventually caught up with them and the predictable happened.
- Paper-Thin Disguise: They disguised themselves as Goombas in Wario the Bankrupt. Bowser was fooled, but Koopa saw through their disguise.
- Second Episode Introduction: Wario makes his first appearance in Goomzilla's second video.
- Those Two Bad Guys: On their worse days.
- Those Two Guys: On their better days.
- Throw the Dog a Bone: An almost literal example in Luigi the Prankster. After being denied any sweets from Peach, tortured by Luigi tempting him with chicken on a string and yanking it away from him, and getting himself injured trying to get it on his motorcycle, Wario finally gets his chicken for real, no strings attached.
- Villains Out Shopping: Not only do they receive bills just like everyone else, but they also engage in fair and honest business, such as when they were merchants in Rogueport. Wario also has no problem watching a magic show with some of the people he messed with in the past.
Bowser's newest recruit, and the rival to Koopa for Bowser's affection.
Tropes associated with Kamek:
- Ambiguous Situation: By the end of Luigi's Quest, Kamek gets himself completely weakened by the Diode, and especially with the Diode being presumably destroyed, this is something that would be quite difficult to recover from. His appearance back on his feet in Yoshi and the Lost Egg is technically non-canon, but him still being on Bowser's list of minions in Mario's Unexpected Transformation makes one question things. What's the word on Kamek's condition after all this? Nobody knows. Not even Goomzilla himself. This was later cleared up in Peach's Quest, where Kamek is still powerless, and Mimi has been posing as him for a presumably long time.
- The Dragon: To Bowser in Luigi's Quest.
- Early-Bird Cameo: In Bowser and the Koopas' Staff, Kamek's voice clips from Mario Super Sluggers could be heard on Bowser's phone. He could be the one who created/gave Bowser the magic wand that makes things disappear.
- Hoist by His Own Petard: Solus defeats him by managing to get all of his energy sucked into a Spiked Paragoomba, which was already powered up enough by the Diode by this point. The effect leaves Kamek too weak to stand up.Kamek: Oh, are you serious?
- Mad Scientist: He'd have to be to know so much about how the Diode works.
- Remember the New Guy?: His first appearance in Luigi's Quest under Bowser's rule comes completely out of nowhere, yet Bowser accepts his presence, no questions asked. On the heroes' side, Mario and his friends are alarmed by Kamek as if they have crossed paths before, but again have never met him prior in this series.
- The Rival: To Koopa for Bowser's affection.
- Something We Forgot: He never gets his power restored to him in Luigi's Quest.Kamek: Hello? A little help here?
- Unexplained Recovery: Those who saw his appearance in the trailer for Yoshi and the Lost Egg and were hoping for an explanation on how he survived total depowering in the previous episode were quite disappointed. Subverted in that he wasn't, that was just someone impersonating him.
- Verbal Tic: He addresses Bowser as "my king" a lot when they interact.
- Villain Respect: He acknowledges Peach's intelligence in Peach's Quest, especially considering she used that intelligence to piece together where she found him.
Doopliss & Tripliss
Two sneaky Duplighosts who love to impersonate people.
Tropes associated with Doopliss & Tripliss:
- Affectionate Nickname: Apparently, "Slick" is one Duplighosts give to each other.
- Ascended Extra: Doopliss went from being a one-off villain in Luigi's Quest to an active antagonist in Peach's Quest.
- Brought to You by the Letter "S": The bowtie on Tripliss' chest is shaped like a giant T.
- Co-Dragons: To Mimi.
- For the Evulz: Doopliss didn't have a clear motive for the things he did in Luigi's Quest. He's just bad for the sake of being bad. Peach's Quest looks like it might fix this.
- Grim Up North: The Crystal Palace, located far up in the north, is the home base of the Duplighosts, and has been for as long as they existed.
- Honor Among Thieves: They act like true friends to each other, complimenting each other on how convincing their disguises are. There's also the whole "raising the captain of a legendary cruise ship" thing.
- It Only Works Once: When Luigi gets to Bowser's Castle in Luigi's Quest, he falls for Doopliss' trick when he posed as Captain Toad. But because Solus warned him later of Doopliss' presence, when he tried to trick Luigi by pretending to be Mario, Luigi wasn't fooled.Doopliss: Heh...you already know I'm not really Mario. You're pretty slick, aren't you, Luigi?
- Kick the Dog: Doopliss' near-exposing of Solus.
- Lone Wolf Boss: They have no affiliation with Bowser or Solus in Luigi's Quest, but they do serve a higher power in Peach's Quest.
- Manchild: Doopliss appears to have some shades of a childish personality, as he says "You guys are no fun" when he has been exposed as Bootler's impostor.
- Pet the Dog: Doopliss looked after the captain of the Great Glory when he was young.
- Plot-Irrelevant Villain: Doopliss in Luigi's Quest. He has a personal vendetta against Luigi after being exposed by him, but has nothing to do with the Diode plot. This changes in Peach's Quest, where Duplighosts are the primary antagonists.
- Pre-Asskicking One-Liner: Doopliss gets one in Luigi's Quest before he fights Luigi.Doopliss: No more playing around. It's showdown time!
- Stage Name: "Mr. Everybody" for Doopliss.
- Suspiciously Similar Substitute: In Luigi's Quest, Doopliss was this to Koopa from Mario's Quest, who disguised himself as a Toad at one point in the movie.
- Terrible Trio: With Mimi.
- Those Two Bad Guys: Notably the only two Duplighosts that we've seen.
- Villainous Crush: Doopliss apparently has a crush on Princess Daisy. When Luigi hears of this, he was shocked.
- Villain with Good Publicity: Despite all the terrible things Doopliss has done in Luigi's Quest, he's apparently likable enough to be a part of a magic show hosted by the Toads in Peach's Quest. He's also apparently a good father to the captain of a legendary cruise ship.
- Debut: Wario the Bankrupt
An octopus that Luigi accidentally caught while fishing, who tends to have problems with his teeth.
Tropes associated with Blooper:
- Berserk Button: He literally goes berserk when one of his teeth gets ripped out in Wario the Bankrupt.
- Karma Houdini: He steals a Shy Guy's TV and gets away with it thanks to Wario and Waluigi's incompetence in police duty.
- Non-Malicious Monster: In Luigi's Quest, at least. Solus claims him to be a "vicious sea creature". But really, he was in pain because of his missing tooth. This may come across as a clue that Solus is not the ally he's cracked up to be.
- Thou Shalt Not Kill: It's implied that Blooper knows how evil Solus is, yet he never straight-up kills him when he keeps trying to take the Energy Cell from him in Luigi's Quest.
A nerdy chameleon who lives in a secluded fortress in the Western Plains. He enjoys the privacy of his own home playing his video games or chatting with friends, and is also very strict about his defenses.
Tropes associated with Francis:
- Adaptational Nice Guy: This version of him is more sympathetic than he was in Super Paper Mario.
- Break the Haughty: Francis cries when his limited-edition Lady Bow poster gets destroyed. Even Luigi and Captain Toad feel a little guilty for indirectly breaking it.
- The Collector: Goomzilla even outright calls him one in one of his descriptions for Yoshi and the Lost Egg.
- Freeze-Frame Bonus: A picture of him and Whacka can be seen in his room, hinting that those two may have had some kind of relationship or past.
- Mr. Exposition: Sort of. He clears up the strange events of the canon path in Yoshi and the Lost Egg when you reach the best ending.
- Nerd: He wears nerd glasses and is almost always seen in front of his laptop.
- Nerd Glasses: He just wouldn't be Francis without 'em.
- Odd Friendship: With Kent C. Koopa, apparently.
- Official Couple: With Birdo, presumably.
- Pre-Asskicking One-Liner:Francis: Nerr! You tricked me! Room into lockdown mode!
- Tears of Joy: Goomzilla actually sews one up for him when Luigi and Captain Toad replace the Lady Bow poster that they accidentally broke earlier.Francis: *sniffle* You guys are the best.
- Verbal Tic: He likes to say "nerr" in his sentences.
- Villainous Breakdown: When Francis realizes he's been tricked by Luigi and Captain Toad when they got his Energy Cell, he snaps, locks them in his room and attacks them. Then he cries when his limited-edition Lady Bow poster gets destroyed in the process. Although "villainous" might not be the right word here, since his only crime was guarding the Energy Cell that they needed.
- Debut: Luigi's Quest
- Adult Fear: Her baby has been kidnapped by Wario and Waluigi in Yoshi and the Lost Egg, and she thinks Yoshi's responsible.
- Disproportionate Retribution: If you believe that the Yoshis stole your baby, the perfect solution is to steal their egg. I promise, it'll totally work.
- Fantastic Racism: It's said that there is sometimes tension between the Yoshis and Birdos, implying this.
- Give Geeks a Chance: If she really is in a relationship with Francis.
- In the Hood: When she steals Yoshi's egg.
- Mama Bear: Whether it's stealing eggs when she thinks her baby's been kidnapped, or freaking out when her baby appears on stage, Birdo is very protective of her child.
- Official Couple: With Francis, presumably.
Master Hand & Crazy Hand
- Debut: Bowser and the Koopas' Staff
Two evil floating gloves that reside in the Underwhere, where those unfortunate to touch their wand hand are forced to go—with an appetite for the heroes that they have captured.
Tropes associated with Master Hand & Crazy Hand.
- Adaptational Villainy: The Hands here have the strangest craving for the heroes that they have captured, in contrast with the desire to simply do battle with them in their home series.
- Big Bad Duumvirate: They are the main antagonists of Bowser and the Koopas' Staff.
- Canon Immigrant: It's rather odd seeing these two in a video series populated entirely by Mario characters, when they themselves are more associated with Super Smash Bros. than Super Mario Bros..
- The Fourth Wall Will Not Protect You: In The Stinger, Master Hand uses the magic hand staff to poof the viewers out of existence.
- Karma Houdini: Crazy Hand manages to recapture a Goomba, but his fate was left ambiguous. Goomzilla himself has stated in the video description that Crazy Hand has also succeeded in eating him, with no comeuppance to boot. In Goomzilla's words, "he's just that crazy."
- Knight of Cerebus: A Goomzilla series first. Bowser's earlier shenanigans in Goomzilla's previous three videos were played relatively lightheartedly, but when we see their world and these two show up, things get serious.
- No Honor Among Thieves: The two Hands fight when Crazy Hand accuses Master Hand of eating all their "food".
- Shock and Awe: Master Hand needed a cord to power himself up, but Crazy Hand could charge himself without the need of one, obviously.
- Those Two Bad Guys: They make Wario and Waluigi look like saints.
- Vader Breath: Instead of using their Evil Laugh from their home series, Goomzilla voices heavy breathing for them, which sounds a bit like this.
A friendly Goomba who befriends the princess during her latest kidnapping.
- But Now I Must Go: Goomfrey has to leave Peach because "humans and Goombas should not mix."
- Disney Death: It looked like Bowser killed Goomfrey when he tried to fight for the princess, but he came to eventually.
- Hidden Depths: He apparently makes excellent tea.
- Minion with an F in Evil: Even before Goomfrey rebelled against Bowser, he was hardly evil to begin with.
- Perpetual Frowner: Even when he's bonding with Peach.
- Suddenly Voiced: Sort of. Goomfrey's sound effects were taken from Mario Super Sluggers, but his crying was voiced by Goomzilla himself.
An endangered species of moles that keep getting beaten up by people they try to talk to.
Tropes associated with Whacka:
- Because You Were Nice to Me: The reason Whacka protected Peach and Goomfrey from a Boomerang Bro.? They were the only people who didn't try to beat him up in any way.
- Butt-Monkey: Everybody he tries to talk to beats him up in some way. Well, almost everybody.
- Famous Last Words: "Quick, run..."
- Heroic Sacrifice: He dies protecting Peach and Goomfrey.
- Killed Off for Real: Unlike everyone else who turned to stone, Whacka remains dead.
- Mad Libs Catch Phrase: "Don't [verb] me!" whenever people beat him up.
- Tempting Fate: The first Whacka is confident that nothing could go wrong today...before Mario whacks him.
- Verbal Tic: "Whackoo" and "whackadoo".
- Debut: Luigi's Quest
A treasure-hunting professional who helps Luigi in Luigi's Quest.
- And Now for Someone Completely Different: Goomzilla ususally narrates his plush tutorials, but the one for Captain Toad was narrated by his sister instead.
- Big Damn Heroes: Captain Toad saves the day in Luigi's Quest by blasting Solus' ghostly head with a machine he made all by himself. This was after Solus mocks him for his inability to jump.
- Butt-Monkey: Captain Toad always seems to get the short end of the stick in Luigi's Quest. His inability to jump doesn't help.
- Gadgeteer Genius: Captain Toad manages to build a ray gun in Luigi's Quest on his own.
- Heroic Mime: Goomzilla doesn't provide a voice for him, despite being fine with voicing other Toads in the series.
- The Lancer: To Luigi in Luigi's Quest.
- Leeroy Jenkins: He makes the impulsive move of attacking Bowser at one point, prompting the latter to chase the former throughout the castle.
- My God, What Have I Done?: He and Luigi feel really guilty for accidentally breaking Francis' Lady Bow poster in Luigi's Quest.
- Perpetual Smiler: Like all the other "smiley face" plushes, he always has a bright smile on his face, even when he's in some kind of danger.
- Suspiciously Similar Substitute: Somewhat one to Kolorado. They both long for adventure in explorer's outfits and are the end result of a bit of slapstick, but Captain Toad's normal pursuit for treasure is not focused on here, he's more capable than Kolorado, and he ultimately stops the bad guy in the end.
A professional hypnotist from Rogueport, who Bowser recruits for his latest plan.
Tropes associated with P. Shroom:
- Angry Eyebrows: True to Poisoned Mushrooms.
- Hypno Pendulum: Keeps one in handy for hypnosis. It's actually a coin tied to a rubber band.
- Hypnotize the Princess: Bowser gets him to hypnotize Peach when she tries to use Mario's power against his minions.
- Karma Houdini: An almost literal Houdini in this case, as he goes through the trouble of hypnotizing Peach to be loyal to Bowser without suffering any consequences. Even worse is that Bowser has presumably rewarded him nicely for his troubles.
- Institutional Apparel: He's a living poisoned mushroom wearing black and white stripes. Subverted in that he's not incarcerated per se.
- Invisible Anatomy: Despite having no arms, he can still pick things up and swing them just fine.
- No Mouth: And yet he can speak okay.
- No Name Given: "P. Shroom", short for Poisoned Mushroom, is just the name Goomzilla gives him in the credits. His actual name is not said in the story.
- Only in It for the Money: Just like his fellow Rogueport criminals, their services will gladly be provided to Bowser if he rewards them nicely. Unlike Wario and Waluigi, however, who just take the money and run, they make more of an honest effort to get the job done.
- Psycho for Hire: More like a Psycho Psychologist for hire, but he still fits the bill.
- The Un-Reveal: How exactly does Kamek know this guy anyway?
- What Happened to the Mouse?: He completely disappears from the rest of the story after he's done hypnotizing Peach, not even seen back in Rogueport.
Lady Bow & Bootler
Two ghosts who reside in a haunted house in the Eastern Woods.
Tropes associated with Lady Bow & Bootler:
- Adaptational Nice Guy: Lady Bow isn't quite as feisty as she was in Paper Mario 64.
- Adaptation Dye-Job: The Lady Bow in Paper Mario 64 had a green coloration instead of this one's white.
- Official Couple: They're clearly in love.
- Debut: Yoshi and the Lost Egg
The leader of the Yoshi clan.
Tropes associated with the Village Leader:
- Big Eater: Possibly, as the Yoshis surround him with fruit in the beginning of Yoshi and the Lost Egg.
- Large and in Charge: His Yoshi plush is huge compared to the other Yoshis he's leading.
- Reasonable Authority Figure: One of the more bittersweet endings has him gently comforting Blue Yoshi over the loss of her egg.
- What the Hell, Hero?: He reprimands Blue Yoshi for letting her guard down, and the reprimanding continues in the worst ending.
- Debut: Luigi's Quest
A mysterious hooded figure from the sea town of Rogueport. Once a minion of Bowser, he grows sick of his tyranny and quits. Now he helps Luigi recover the Energy Cells needed to save Mario and Peach, mostly to teach Bowser a lesson...though he might have some other ulterior motive for all of this.
Tropes associated with Solus:
- Back from the Dead: Twice! Once as a Dry Bones, then as a ghostly head.
- Badass Normal: Even before getting himself powered up by the Diode, Solus can look after himself in an enemy threat. That said, he's still far from a match for the guardians of the Energy Cells in this state.
- Big Bad: The true villain of Luigi's Quest. The Diode was his idea from the very beginning.
- Big-Bad Ensemble: With Bowser. Solus may have been secretly plotting to use the Diode for himself, and started Project Diode originally, but who was the one that sent Kamek to capture Mario and his friends? Bowser. He also was the one who planned to use the Diode to power up Peach, then came up with the idea to take her to a hypnotist when she tries to use Mario's power to save him, since in his words, "she needs to be more loyal to me". Solus had nothing to do with any of that, and most likely didn't even know that Peach was under Bowser's control at all.
- Borrowed Catchphrase: "So long, eh, Bowser?"
- Dark and Troubled Past: Once Bowser's closest minion, Solus was a Koopa Troopa who accidentally fell into the lava, leaving himself as a Dry Bones. Bowser doesn't recognize him, and it all goes downhill from there.
- Deader Than Dead: Actually even deader than deader than dead. He accidentally fell into a pit of lava, which stripped him of his skin, but he came back as a Dry Bones. When first defeated by Luigi and Koopa, he disappears, but becomes a near-invincible ghostly head. But then Captain Toad stepped in and zapped him into oblivion with a ray gun he built, destroying the monster once and for all.
- Evil All Along: Double subverted. He was first believed to be a good guy, but then he betrays the heroes and takes down Bowser on his own. After that, he acts like it's a happy ending for the Mario Brothers. And then we arrive at his headquarters...
- Evil Mentor: Revealed to be this in the climax.
- Family-Unfriendly Death: Thankfully, the horrific burning of his flesh occurs off-screen.
- Famous Last Words: "No...no...I had the power of Super Mario, and I lost to the lesser brother? This can't be the end..."
- Forgotten Fallen Friend: As if Bowser failing to recognize him when he falls into the lava and becomes a Dry Bones isn't scarring enough, Bowser never seems to show visible signs of wondering what happened to Solus in the first place, even after ten years have passed. Keep in mind that Solus was once Bowser's closest minion.
- Hypocrite: He called Luigi selfish, ignoring the fact that he used Luigi all this time.
- In the Hood: Wears a hood for the most of Luigi's Quest.
- Kick the Dog: After potentially killing Bowser in front of the loyal Koopa's eyes, he decides to rub salt in the wound."So Koopa, how does it feel to know your precious ruler has fallen?"
- Killed Off for Real: Confirmed in Peach's Quest, where Kamek all but says that the Spiked Paragoomba that absorbed his magic has to die in order for his power to be restored—which is exactly what happened for Mario when Solus' soul was blasted into submission.
- Knight of Cerebus: Once he reveals his true colors, the tone of Luigi's Quest becomes much more serious.
- The Man Behind the Man: He was the mastermind behind the Diode.
- Mad Scientist: He started Project Diode, and the final battle takes place in his headquarters.
- Meaningful Name: Some may say his name is a pun of soulless, but his name actually comes from the Latin meaning of "alone", like "solitude". While his name fits for both reasons, the latter better suits how alone he felt after Bowser failed to recognize him, and how he strives for no one's goals but his own.
- The Mentor: To Luigi. Or so it seems at first...
- Obviously Evil: An unintentional example. Despite Goomzilla's best efforts to keep Solus' true nature a secret until The Reveal, it didn't stop a lot of his actions and lines from earning suspicion from the less trusting viewer.
- One-Winged Angel: His ghostly head form.
- Palette Swap: Before the accident, his Koopa Troopa plush was the same one used for Koopa, just with hair sticking up.
- Pre-Asskicking One-Liner: In his final battle with Koopa and Luigi in Luigi's Quest"If that's how it is, I'll fight you too, Koopa. Prepare for the end!"
- "The Reason You Suck" Speech: He gives a hefty one to Bowser.Solus: So, King Bowser, do you remember me? [beat] No, of course you don't. I used to be your closest minion. But then one day, whilst cleaning the walls in the basement, I slipped and fell into the lava. I had this burnt, dry body. When I reported back, you didn't recognize me. You wouldn't let me anywhere near you. You only had eyes for your newest #1 minion, Koopa. Eventually, you ordered me to leave your castle. I couldn't believe it! My loyalty to you had been for nothing! Well, now I'm here with the power of Super Mario, and I'm going to be the one who defeats you!
- Treacherous Advisor: He tells Luigi to fetch all of the Energy Cells in the castles stored around the earth, but then he double-crosses him and takes all of Mario's power from Peach.
- Villain Has a Point: Before The Reveal, he tells Luigi that Bowser only sees his minions as tools and not as allies. Given Bowser's worrying descent into Bad Boss territory in Goomzilla's series specifically, up to and including not caring when they get turned into stone, this gives Solus' story credence. The credence is further supported by Bowser not being shown wondering what happened to Solus these past ten years.
- Woobie, Destroyer of Worlds: The most despicable villain in Goomzilla's videos to date, yet you can't deny what he's been through.
- You Know What to Do: Tells this to Luigi when it came to powering up the Diode with the Energy Cells.
- Debut: "Peach's Quest"
- Big Bad: Of Peach's Quest.
- Brainwashed: She claims to have done this to Bowser's minions, when it was really more a case of lying to them.
- Dark Action Girl: The first female antagonist in a Goomzilla video.
- Fluffy the Terrible: To the other characters in the movie, "Mimi" doesn't sound like a very threatening name. Then again, they didn't know yet that she's the leader of the Duplighosts, and only saw the name in a book.
- Imposter Forgot One Detail: While posing as Kamek, she drops his Verbal Tic of addressing Bowser as "my King". Oddly, Yoshi and the Lost Egg shows she had no problem with this. Of course, that was a non-canon ending anyway.
- Terrible Trio: With Doopliss and Tripliss.
- Voice of the Legion: Done much more convincingly than Hypnotized!Peach.
