Blathering Blatherskite!
~ Fenton Crackshell-Cabrera
Fenton Crackshell-Cabrera works for McDuck Enterprises. Fenton is the secret identity of Gizmoduck and is Gyro Gearloose's intern. While Gizmoduck keeps his identity a secret, a fair few people have found out anyway, including Gyro Gearloose, Officer Cabrera, Scrooge McDuck, Gandra Dee, Huey Duck, Webby Vanderquack, Dewey Duck, Launchpad McQuackMark Beaks, the mailman, the dry cleaner, a barista at Starducks, and everyone who lives on his block.


Fenton Crackshell-Cabrera lives with his mother, Officer Cabrera. Fenton was a Junior Woodchuck when he was a kid.[1] Sometime prior to Woo-oo!, Fenton got a job working at Gearloose Labs with Gyro Gearloose as an unpaid intern. Fenton helped Gyro Gearloose to create a robotic suit of armour, the Gizmosuit. Fenton was rather eager to try the Gizmosuit out, but Gyro wouldn't allow it, as Gyro wanted to wait until the suit was completely ready.

After Fenton used the Gizmosuit to save Gyro Gearloose, Scrooge McDuck, Dewey Duck, and Mark Beaks from a car driven by the out-of-control B.U.D.D.Y., Fenton dubbed himself Gizmoduck. Later that day, Gyro gave Fenton permission to keep using the Gizmosuit for beta testing. Fenton promised Gyro he wouldn't tell anyone about the Gizmosuit (except for Dewey and Launchpad, who already knew). Fenton was also not to use the Gizmosuit for anything other than basic testing. Fenton often broke this rule, especially after a remark Huey Duck made on the news caused Fenton to realise that as Gizmoduck he could be a hero.

The most notable flaw in the Gizmosuit was that using too many gizmos at once overloaded the core processor, causing two close shaves with the suit attempting to self-destruct. Huey was ultimately able to solve this problem by scrapping the processor and using Fenton's brain to control the Gizmosuit instead. Immediately afterwards, Fenton got caught in an explosion in the process of saving Duckburg and passed out. When Fenton woke up in the hospital, Scrooge offered him a paid job protecting Duckburg whenever Scrooge himself couldn't be there to defend it, since he frequently adventures abroad.

While Fenton was viewing the lunar eclipse, Magica De Spell brought his shadow to life. Fenton activated the Gizmosuit, but Fenton's shadow shoved him out of the way and stole it. Fenton helped fight the shadows later by plugging Lil Bulb into a laser Gyro invented. Fenton was present when Donald Duck destroyed Magica's staff, and for the celebrations afterward.


Fenton Crackshell-Cabrera

Fenton Crackshell-Cabrera is a light brown duck with unruly pompadour hair. He is about three-and-a-half feet tall. He wears a cream colored dress shirt and a light purple necktie.


As Gizmoduck, Fenton wears a suit of bulky white robotic armour with black arms and red highlights. It has a red "G" logo on the chest that resembles a shooting star. The Gizmosuit is supported on a single wheel. It has a helmet with a purple visor. The Gizmosuit adds roughly two-and-a-half feet to Fenton's height, making Gizmoduck about six feet tall. The only organic part of Fenton Crackshell-Cabrera visible under the Gizmosuit is his beak.


Fenton is determined, optimistic, earnest, and brilliant. More than anything, Fenton wants to help people and make the world a better place. Fenton also wants to prove himself. Sometimes he tries a little too hard and things don't turn out quite the way he wants them to.

Fenton is very enthusiastic, especially about his work. Fenton's brain is full to bursting with ideas, and he never stops thinking. Fenton speaks a mile a minute and has a habit of using large and/or unusual words, most famously 'Blathering blatherskite!' Other examples include: "illumination", "salvation", "calamitous", and "cataclysmic".

Fenton drinks hot water with his breakfast to stimulate brain activity.[2] Fenton doesn't drink decaf.[3] Fenton loves glazed doughnuts.


Fenton is very good at coming up with ideas. Not all of them work, but he more than makes up for it with the ones that do work. Fenton is great at thinking while under pressure, instead of panicking. Fenton is good at inventing things, often at a moment's notice; he once turned Lil Bulb into a laser blaster to fight Magica De Spell's shadows. Fenton is highly observant (i.e. while testing the Gizmosuit, he was able to identify the flavours of the pies shooting out of it without tasting them). Fenton can understand Morse Code.

As Gizmoduck, Fenton has all of the Gizmosuit's gizmos at his disposal. These include: Shoulder Blades, Pectoral Parachute, Gluteal Grapple, Helmet-copter, Turbo-Wheel, Pietillery, Laser Cannon, Ballpoint Pointer, Extendo-arms, Elbow Grease, Finger Gun Lasers, Hip-flexor Extendo-abs, Wrist Rockets, Radial Reflectors, Deltoid Turbines, Gearloose "Back Hands", Midriff Missiles, Bagpipes, Air Horn, Screwdrivers (Phillips-Head and Regular), Can Opener, Mustard Dispenser, Confetti Cannon, Rocket Launcher, Rocket Thrusters, and Flamethrowers, among many others. The armour also gives Gizmoduck enhanced strength and durability.


Friends and Colleagues

Gandra Dee

'Gandra doesn't care about Gizmoduck. She likes me!' — Fenton Crackshell-Cabrera

Fenton first met Gandra at an electronics store and he was instantly smitten. The two quickly arranged a date at the lab for that night. Over the course of the date, the two bonded over Fenton's inventions. However, midway through, Huey and Webby told Fenton that they had just discovered that Gandra was a spy for Mark Beaks. Fenton angrily confronted Gandra about this, at one point saying the Gizmosuit's passcode. Unfortunately, this was exactly what Beaks had wanted. He used the audio recording of Fenton's voice to activate the nanites Gandra had made for Beaks with stolen Gizmo Tech. This caused Beaks to turn into a giant, hulking monster. Gandra initially helped Beaks subdue Fenton, but switched sides when Beaks kept trying to hurt Fenton after Fenton lost the protection of the Gizmosuit. After Fenton and Gandra defeated Beaks together, Gandra competed Fenton's equations for Fentonium.

Huey Duck

'He was smart, and noble, and made of metal. Everything I've always wanted to be, almost.' — Huey Duck

Huey is Fenton's best friend, just as Dewey is Launchpad's best friend. Huey idolises Gizmoduck for being smart and noble. When Fenton was having trouble controlling the Gizmosuit, Huey rewired it to directly run through Fenton's brain. Huey reminded Fenton that the suit isn't Gizmoduck, Fenton is.

Gyro Gearloose

'I have a job at McDuck Enterprises under the best scientist in the city!' — Fenton Crackshell-Cabrera

While Fenton thinks highly of Gyro as the best scientist in the city, Gyro doesn't give Fenton equal respect. This is because Fenton is so eager to prove his intellect and his abilities, that in the process he makes multiple mistakes and makes a mess of things. Gyro thinks so little of Fenton's ideas that Gyro had Fenton make the bathroom his private laboratory, because that's where Gyro thinks Fenton's ideas belong.

However, after Fenton was hospitalized after saving Duckburg from being blown up by the Gizmosuit's old core processor, Gyro risked his funding by telling Scrooge everything about Fenton and the Gizmosuit. When Gyro and Scrooge visited Fenton in the hospital, Gyro gave Fenton the Gizmosuit for Fenton to use to help him be Duckburg's superhero.

After Fenton used his Fentonium to recharge Lil Bulb, Gyro nodded approvingly.

Scrooge McDuck

'I need someone to make sure this place is still standing when I get back.' — Scrooge McDuck

Scrooge has significantly more faith in Fenton than Gyro has. When Fenton was hospitalised after saving Duckburg, Scrooge paid for Fenton to stay in the VIP hospital suite and offered Fenton a paid job defending Duckburg.

Launchpad McQuack

'I'm ready to prove my worth by aiding Mr. McQuack!' — Fenton Crackshell-Cabrera

After Launchpad McQuack challenged B.U.D.D.Y. to a car race, Fenton did everything he could to help Launchpad win. When B.U.D.D.Y. later went berserk, Launchpad and Gizmoduck teamed up to save everyone. Just as B.U.D.D.Y. was about to drive Gizmoduck off a cliff, Launchpad saved him in the limo. When the ground crumbled beneath the car (with Launchpad, Gizmoduck, and Dewey in it) Gizmoduck used his Helmet-copter to fly the car to safety.


Mark Beaks

'You've always been a monster, but now you are a literal monster.' — Fenton Crackshell-Cabrera

Mark Beaks is Gizmoduck's Lex Luthor.[4] Mark Beaks and Fenton briefly met the day Fenton first became Gizmoduck and saved Beaks along with everyone else. One look at the Gizmosuit was all it took for Beaks to become obsessed with it.

Later, he built a device to control the Gizmosuit, manipulated Gizmoduck into working for Waddle, and after Fenton ultimately quit Waddle, Beaks stole the Gizmosuit. After Beaks's incompetence at using it nearly killed everyone, Fenton took the Gizmosuit back.

  • Fenton Crackshell-Cabrera is played by Lin-Manuel Miranda. In an interview, Miranda said that Fenton Crackshell-Cabrera and Alexander Hamilton have a lot in common and would be friends if they met.[5]
  • The second half of Fenton's surname, Cabrera, is a reference to his m'ma's stubbornness (Cabrera means "goatherd"). According to Francisco Angones, the Cabrera family have traditionally been protectors, peacekeepers, and lawmen. The Crackshells were all crackpots and kooks. Fenton is the logical heir to both sides of his family.[6]
  • Fenton's line: 'Go, you bumblebee-like savant! Go!' was an ad-lib by Lin-Manuel Miranda. It is Francisco Angones's favourite line of Season 1.[7]
  • In Who is Gizmoduck?! we see Gizmoduck write with both hands. It is currently unclear if this is a feature of the Gizmosuit, or if Fenton is naturally ambidextrous.
  • Fenton was originally supposed to debut as a cameo in Woo-oo!, helping Gyro Gearloose get the sub ready for Scrooge's trip to Atlantis. Fenton and Gyro would have also cameoed in other episodes, as a running gag about how Gyro can't remember Fenton's name. These scenes were ultimately cut to give other characters more focus, and because the writers felt Fenton and Gyro deserved a better introduction.[8]
  • In Ducktales (1987), Fenton Crackshell was an accountant with a talent for accurately counting huge numbers of things very quickly. In Ducktales (2017), Fenton's name has been extended to Fenton Crackshell-Cabrera, and he has been reimagined as a scientist with Latin roots. Ironically, considering that Fenton Crackshell-Cabrera worked for Gyro and is constantly belittled by him, on several occasions Fenton Crackshell called Gyro Gearloose a "wacko" and a "crackpot". (Also, in The Dangerous Chemistry of Gandra Dee! Fenton is upset that people call Fenton a crackpot.)
  • Fenton likes purple ties.
