An abandoned Pomeranian puppy that Edgeworth adopts right after the class trial that brought Phoenix and Larry together.
- Canine Companion: He develops a particular attachment to Edgeworth after meeting him, and spends much of his time around him during his childhood.
- Cuteness Proximity: His Puppy-Dog Eyes wind up guilt-tripping Larry into turning the money Missile picked up over to the police instead of keeping it for himself.
- Fake Crossover: He bears the same name and design as Missile from Ghost Trick, another Shu Takumi creation, who was based on Takumi's real Pomeranian.
- Named by the Adaptation: His name is never stated in the Japanese version, while he's called "Missile" in the English dub.
- One Steve Limit: Averted. He shares his name with the K-9 police dog, who was reduced to a cameo in the anime's second ending sequence to show the two are distinct dogs.
- Small Role, Big Impact: In the anime adaptation, he's the one who takes the money Phoenix is accused of stealing from Edgeworth after the latter drops it by mistake, leading to the class trial that set Phoenix's path to becoming a defense attorney in motion; Larry simply coaxes it from the dog and takes it to the police, and simply forgets to bring it up.
- Unwitting Instigator of Doom: Zig-Zagged. If he hadn't brought Edgeworth's lunch money to Larry, Phoenix wouldn't have been accused of stealing it. On the other hand, the three boys never would've become lifelong friends.
Goldy Gerwitz (Harami Jorosu)
Voiced by (Japanese): Kimiko Saito (anime)
Voiced by (English): Christopher Sabat (anime)
A portly woman who has a run-in with the von Karma family—including a younger Miles Edgeworth—at Lordy Tailor in 2004 when she claims ownership of a missing Pomeranian named Napalm.
- Adaptational Villainy: The English dub goes as far to say that Goldy is an ex-convict when she cries she's Never Going Back to Prison.
- Always Murder: A rare aversion for the series in that she is not involved in the death of anyone in any sort, let alone any actual crime.
- Animal Motifs: She dresses like a cow with a spotted coat and a bell around her neck, and her hair points up in a manner resembling bull horns when she has her Villainous Breakdown.
- Didn't Think This Through: She tries tricking Edgeworth into handing over a missing dog with a hefty reward by pretending to be its owner so she could hog the money to herself. She never counted on Edgeworth hearing the same report, which triggers her Villainous Breakdown when he asks her for the reward money since he found the dog first.
- Expressive Hair: Her hair points up in the shape of bull horns when Edgeworth incurs her wrath.
- Fat Bitch: She is a very plump and unpleasant Jerkass of a woman.
- Glowing Eyes of Doom: Her eyes glow red when she looks like she starts rearing at Edgeworth.
- Greed: She wants to keep the $5,000 reward for a missing dog all to herself, and tries to stop Edgeworth from beating her to the punch.
- It's All About Me: When proves how self-centered she is when she sees that Edgeworth has found a dog worth a sizeable reward and tries to swindle him out of it so she can hog the prize.
- Punny Name: "Goldy Gerwitz" sounds an awful lot like "gold digger".
- Tears of Fear: When Manfred von Karma dares her to take things up in court against him, her response is to run away crying like a baby.
- Villainy-Free Villain: Technically speaking, her underhanded plan to claim a handsome reward for a missing dog isn't exactly illegal, since she'd still have to return the dog to its rightful owner; it's just that she's motivated purely by greed and selfishness, whereas Edgeworth feels the reward would be put to better use as a charitable donation. The English dub downplays this by having her state she can't go back to prison.
- Villainous Breakdown: After Edgeworth demands she stay true to her ownership of Napalm by paying him the $5,000 reward she's after, her hair curls up into a pair of bull horns and she starts pawing the ground with her foot like she's about to charge him.
- Vocal Dissonance: The English dub of the anime gives her a deep, masculine voice courtesy of Christopher Sabat.
- Womanchild: She shows hints of it when she starts singing the theme to Signal Samurai, a children's show whose music she'd just heard on the radio, and later when she runs away crying like a baby after getting beat.

A radio DJ who ran the lunchtime slot in 2004.
- Accidental Hero: By playing the Signal Samurai theme on the radio as a request for Phoenix when she does, she inadvertently provides Edgeworth with evidence against Gerwitz claiming ownership of a missing dog.
- One Steve Limit: She averts this by sharing her name with Dee Vasquez.
- Punny Name: "Dee" is the first part of "DJ", while "Tomorina" contains the Japanese word for "friend" (tomo), befitting a "lunchtime buddy".
- Small Role, Big Impact: In a roundabout way, if she hadn't played the Signal Samurai theme on the radio at Phoenix's request for Edgeworth, then Edgeworth wouldn't have demonstrated his keen prosecutorial skills in front of Manfred von Karma, who officially molds him into becoming one of Phoenix's fiercest rivals.
- The Voice: She's only ever heard over the radio.

A female Pomeranian who gets lost in Lordly Tailor.
- Distaff Counterpart: She's essentially a female Missile (Edgeworth's Pomeranian, not Gumshoe's Shiba Inu) with a similar name.
- Meaningful Name: Napalm is a flammable adhesive gel that's used in warfare. Moreover, it matches well with the name of her male counterpart, Missile.
- Tertiary Sexual Characteristics: You can tell she's a girl by the pink bow and heart-shaped belly spot.
- Tropey, Come Home: She gets loose in the biggest shopping mall in town, with a whopping $5,000 (500,000 yen) reward for her safe return.
