Beware the Nice Ones: Taunting him about his father or trying to make a move on Faline shows his ugly side.
Break the Cutie: Happens in the first film when his mother dies and his father tells him off about what happened. Happens again in the midquel, once Bambi's hope of his mother being alive get dashed, as well as getting berated by his father for falling for the hunter's trick.
Death Glare: Actually gains one in the midquel, most notably before he buck-kicks a ferocious hunting dog off a cliff.
Kissing Cousins: With Faline in the original novel. Bambi and Faline are still listed as cousins in some licensed books based off the Disney version. Whether or not it's canon in the movies but never mentioned is unknown.
Right before engaging in combat with Ronno for trying to separate him from Faline.
Repeated in the midquel when Ronno presses Bambi's Berserk Button by taunting him because his father sent him off to live with another doe.
Like Father, Like Son: The end of the first movie implies that, as in the novel, he became aloof like his father when it shows him standing besides said father, observing Faline and their newborn children from a distance.
The Quiet One: In the original film, Bambi has a rather limited number of lines, usually emoting more from facial expression. In the midquel, while still more reserved than Thumper, he is much more talkative.
Shrinking Violet: To an extent, Bambi is portrayed as somewhat shy and insecure, especially as a fawn.
Voiced by: Peter Behn (young), Tim Davis (adolescent), Sam Edwards (adult), Brendon Baerg (Bambi II)
Bambi's best friend, a peppy little rabbit.
Big Brother Instinct: Thumper is older than Bambi, so he takes to helping him out as he grows into a Prince, even helping him talk as an infant. Less prominent with his own younger sisters, who chase and bug him to the point of annoyance.
Canon Foreigner: Played with. While Thumper seems to be roughly based off of the novel's Friend Hare, his personality and role were improvised and expanded greatly to help give the film a Lighter and Softer feel.
Character Tics: Thumps his foot to get someone's attention or when excited.
Voiced by: Stan Alexander (young), Tim Davis (adolescent), Sterling Holloway (adult), Nicky Jones (Bambi II)
A minor character in the films, he is friends with Bambi and Thumper.
Ambiguously Gay: Flower appears to be this in the first half of the film...only to have him fall in love with a female skunk during in the second half. In the first portion of the film he is just a kit, whereas later, his voice and size making it rather obvious he had gone through the skunk equivalent of puberty.
Brick Joke: Flower's "Turtles are so scary" line midway through the midquel gets backed up at the end when Ronno winds up with a turtle clinging to his nose.
Dude Looks Like a Lady / Viewer Gender Confusion: Before he grows up. He has a very high, cute voice, and acts very demure and a bit shy, and would rather sit and smell the flowers than go on an adventure. Even after he grows up, his voice gets deeper, the first hint that he is actually a male, but he still looks effeminate.
Kissing Cousins: She was Bambi's cousin in the original novel. This is not addressed in the movie, obviously.
Neutral Female: When Bambi and Ronno fight over her, she just stands against a rock wall and watches. Could be justified by Truth in Television, since female deer are perfectly fine with being battled over during the mating season.
The Owl-Knowing One: Played with. While something of a Know-Nothing Know-It-All he seems genuinely knowledgeable in some areas. In the midquel he is near instantly observant that Bambi would be in better care with his father.
Voiced by: Anthony Ghannam
Adaptation Dye-Job: He has brown eyes in the original, but in the midquel he has green eyes, probably to help further distinguish him from Bambi.
Always Second Best: A partial reason for his growing hatred of Bambi in the midquel, growing rather competitive around him in terms of athleticism and skill.
Took a Level in Badass: Timeline wise, he grows from a cowardly dim witted bully to a rather sinister hulking deer.
Took a Level in Jerkass: Ronno goes from simply making fun of Bambi when they first meet, to deliberately coaxing him into fights and confrontations. As an adult, he even seems to provide an animal example of Attempted Rape when he tries forcing Faline apart from Bambi.
Good Parents: Clearly shown to be a kind and caring mother to Bambi before she dies.
Mood Whiplash: Bambie's mom's death scene is so memorable because the film had been much lighter and softer up until that point. Directly afterwards, there's a cut right into spring with joyful birds singing an upbeat song about the mating season.
Parental Neglect/Parental Abandonment: In the novel she gradually grows more distant to Bambi, eventually abandoning him once mating season arrives. She does come back, however, only to vanish during the hunter's rounds during the wintertime, where it's strongly implicated, but never explicitly stated, that she was killed.
Berserk Button: In the midquel, after he saves Bambi from the hunter and his dogs:
"What if i hadn't gotten to you in time?! You could have been... When I tell you "run", you RUN, NEVER freeze like that!"
Death by Adaptation: There actually is a pro-hurting educational book out there called Little Jake And The Three Bears that has the titular Little Jake off him and one of said bears, as if this will make kids want to be ethical responsible hunters. As if kids weren't traumatized enough by Bambi's mother's death.
The Stoic: In the original film. Initially is this in the midquel, but softens up.
Large Ham: It's really hard to take the Great Prince seriously when you realize that he's voiced by friggin' Picard.
Luke, I Am Your Father: The Great Prince turns out to be Bambi's father midway through the first film. The midquel (which takes place immediately after the death of Bambi's mother) also states early on that he is his father.
Manly Tears: The sign of his full defrosting when he believes Bambi is dead in the midquel.
The Marvelous Deer: Bambi's father is the Great Prince of the forest who guards the woodland creatures from the dangers of hunters.
Mundane Made Awesome: The Great Prince does everything in a ridiculously majestic manner but somehow seems to do it all with his eyes closed.
The Obi-Wan: The Great Prince. This is averted more than halfway through Bambi II, however, when the Prince finally starts to open up and care more for Bambi as a father.
Papa Wolf: Took on hunting dogs to protect his son.
Parental Neglect: In keeping with the semi-realistic deer behavior of the first film, he doesn't seem to have much to do with his son until his mothers death. This comes back to haunt him in the midquel, where he is left to care for Bambi alone.
Spared by the Adaptation: In the original novel, the Great Prince is last depicted leaving Bambi to die of old age. A similar transition of him departing as Bambi takes his place is shown in the film, though his death is not directly implied whatsoever (especially since a lot less time has passed than in the novel).
Was intended to be the stepmother of Bambi, but an encounter with a hunter's trap and his dogs, as well as Bambi bonding with his father, changes this. She was childhood friends with Bambi's mother. Only had a couple minutes of screentime.
Damsel in Distress: Got her back foot stuck in a trap thanks to Ronno and had to be saved by both Bambi and his father.
Meaningful Echo: When the above happens, she says the exact words Bambi's mother said to him before she died.
He Who Must Not Be Seen: Although concept art for the film did show his dead body like the novel did, from a scene that never made it into the final film.
Humans Kill Wantonly: Though not intentional in the film (the reason he was not shown was because Walt didn't want to make him a villain and kids wouldn't understand if he wasn't) the film still seems to send this message.
Humans Are Cthulhu: More so the novel than the film. The novel has a darker tone that extends to the portrayal of the hunter as well. In the film he is more of a occasional hazard, in the novel he always comes with a foreboding atmosphere and is viewed as all powerful, inescapable and so terrifying deer can barely bring themselves to run away.
Not So Different: In the novel, the Great Prince brings Bambi to his dead body for the purpose of teaching him one last lesson. Bambi learns man is not all powerful, he has needs like animals do and dies like animals do, and there is one greater who does not. The Great Prince then calls him son for the first and last time, before going off to die.
The Voice: In the sequel you hear him using deer calls. The deer hear it as "I'm here" or "Hello."
Ultimate Evil: Disney's decision to not show him to avoid vilifying hunters appears to have backfired on Disney as it just made him scarier in peoples minds, so much so he ranked 20 in AFI's 100 Years...100 Heroes and Villains list, making him the only character on that list that is never shown.
