Depending on the Writer: Circumstances could easily have kept Fievel from being as cheerful in the first movie as he was in the second. But his bravery falls to levels that are nearly Out of Character in the Mystery Of The Night Monster movie, considering how almost fearless he is in the other three.
Flanderization: Like everyone in Fievel's American Tails. In the show his fascination with cowboys becomes one of his sole defining characteristics.
Hand-Hiding Sleeves: Fievel has these thanks to his oversized red jersey, which make him seem cute and tell us that he's poor.
Orphan's Ordeal: Goes through this without his parents ever actually dying.
Tagalong Kid: Always manages to involve himself in even the most dangerous situations in the sequels (a shoot-out with Cat R. Waul's gang, an underground expedition for buried treasure, a search for a supposed monster that's eating mice), and no one ever stops him from tagging along.
Just The Way You Are: This is the moral of Tanya Mousekewitz's subplot in Fievel Goes West. She gets a makeover so she can sing at Waul's saloon, but after discovering Waul is actually evil and tried to kill every mouse in Green River, she remembers what her friend Miss Kitty told her, that the real woman is what's underneath the mask, and she washes her make-up off.
Stay in the Kitchen: Mama and Papa agree to let Fievel go on the treasure-hunting expedition in The Treasure of Manhattan Island, but when Tanya wants to go they flat-out refuse. Tanya then complains that her brother always gets to go on adventures while she's stuck at home doing laundry.
Mama Voiced by: Erica Yohn; Susan Silo ("Fievel's American Tails"); Jane Singer ("Mystery of the Night Monster")
Papa Voiced by: Nehemiah Persoff; Lloyd Battista ("Fievel's American Tails")
Fievel's parents. Papa likes to tell tall tales and wholeheartedly believes that there are no cats in America at the beginning of the first film. Mama, however, is much more down to Earth and isn't afraid to tell Papa when she thinks his stories are nothing but fairy tales.
Parental Obliviousness: So, so many examples. They mean well, but they may be candidates for one the most irresponsible sets of parents ever portrayed in animation. In their defense though, they really should keep Fievel on a leash or something.
They refuse to believe that Fievel is still alive in the first movie until the evidence is staring them in the face.
They also won't listen to Fievel when he warns them about Cat R. Waul's evil plans in the second movie. Though to be fair, Fievel had also just told them that he'd run into a tribe of Indians where Tiger was worshiped as a god, so they believed that Fievel was delirious from heat stroke.
Speaking of which, they don't seem to mind the underage Tanya getting a job as a saloon singer at a bar full of cats either.
Their parenting skills Take a Level in Dumbass in Fievel's American Tails, where in "A Case of the Hiccups" they allow Fievel to take candy from a stranger and give it to everyone in town, in "Babysitting Blues" they actually trust young Fievel to babysit Yasha (and she almost gets eaten by cats several times), and in "Little Mouse on the Prairie" they actually force Fievel to take Tanya and Yasha with him on a dangerous journey into the desert where they all get lost and almost die. As if they weren't used to Fievel getting lost whenever he sets foot outside by now.
In The Mystery of the Night Monster, their idea of helping Fievel get over the recurring nightmares he keeps having about the alleged "night monster" is to have him join reporter Nellie Brie so he can hear eyewitness accounts of said monster attacking homes and "devouring" mice. Yeah, that's going to help him sleep better at night.
The only nice cat Fievel meets, and one of his best friends. He's a bit cowardly but he can be brave when he wants to. He's also a vegetarian, so he never eats mice. Fievel Goes West is where he saw the most character development.
Took a Level in Dumbass: Though he was never very bright, he was dumbed down to the point of Too Dumb to Live in Fievel's American Tails, with all of the character development he made in Fievel Goes West gone.
A streetwise orphan that Fievel befriends in the first film while imprisoned in a sweat shop. After Fievel frees everyone Tony takes it upon himself to help Fievel find his family. He's largely absent from Fievel Goes West except for some blink-and-you-miss-it cameos, but he comes back in full main character status in the direct to video sequels.
Vague Age: Probably one of the best examples in the series due to suddenly having a baby with Bridget in the second movie, but acting considerably more childish in the third and seconds films, as well as spending most of his time with Fievel.
Voiced by: Cathianne Blore
Bridget is an Irish mouse-rights activist who Tony meets and falls in love with. She tries to use her ties with the mouse politicians in New York to help find Fievel's family.
A crooked rat with a stranglehold on the mice of New York. He is greedy, selling poor little children like Fievel into sweatshops in exchange for their salary, and running a protection racket on the mice offering them protection from the cats in exchange for money.
Dreadful Musician: Warren plays a very cringe-worthy rendition of "Beautiful Dreamer" on his violin during the sewer scene. He claims it's because "his nose keeps getting in the way". Granted, this may be justified as he is wearing a fake rat nose.
An evil British cat who schemes to eat all the mice of Green River by luring them there with the promise that out west, cats are nice to mice. He's also Wicked Cultured and planned to spare Tanya from the fate of the other mice because he liked her singing voice.
Villainous Breakdown: Starts gradually when Fievel, Tiger and Wylie start getting the upper hand in the final battle, and peaks when Tanya fully exposes his plan.
Villain with Good Publicity: Somehow convinces the New York mice that he's a great guy who would never in his life eat mice. Even more impressive, he continues to convince the mice of this week after week in the TV series.
Originally just a random member of Waul's gang, he becomes a bigger threat in Fievel's American Tails.
Arm Cannon: His "mouse slapper" device that he orders from a catalog in one episode, an arm cannon that shoots nets at the mice. Rather Steam Punk if you consider the time period and setting.
Ascended Extra: Only appears as a background character in Fievel Goes West, but is the main villain in some episodes of Fievel's American Tails.
Jerk with a Heart of Gold: In "Babysitter Blues" when Yasha escapes Fievel and wanders into Sweet William's lair, the usually evil cat can't bring himself to eat such a cute little creature, and later saves her from Cat R. Waul.
Characters From "The Treasure of Manhattan Island"
Voiced by: Elaine Bilstad
Cholena is the daughter of the Chief of an underground tribe of Native American mice, who fled underground with the arrival of European settlers in Manhattan. Fievel befriends her and brings her up to the surface in an effort to prove that European mice aren't bad.
One of three corrupt owners (the other two are listed below) of a cheese factory, who turn it into a sweatshop and later stir the workers into a crusade against the Native American mice living beneath the city.
Big Bad:Of An American Tail: The Treasure of Manhattan Island, along with Toplofty and O' Bloat. He would seem to be the leader of the other two.
An archeologist from the Museum of Natural History that Tony worked for once, who deciphers the map Fievel and Tony find and accompanies their expedition for the 'treasure' under Manhattan that appears on the map.
Nellie Brie is a no-nonsense, down to Earth reporter with a mind for facts. She's also one of the craftiest reporters New York's mice have ever known, and her work for the Daily Nibbler is legendary. She's constantly at odds with her editor, who believes more in selling newspapers than bringing people facts.
The Nicknamer: He nicknames Fievel "Rembrandt" after catching Fievel doodling a picture of him with overly-large ears. He then hires Fievel to draw people's depictions of the Night Monster (mostly just to annoy Nellie).
