The "hero" of the series. He was a Bug Catcher whom Red defeated twenty years ago. This defeat broke his sense of his own self worth, and as a result he is now seeks revenge against Red.
- After Action Patchup: Apparently had the foresight to tie a bandage around Red's Son's head to reduce bleeding. Though he didn't do a good job of it.
- Bad People Abuse Animals: Ralphie has kept his Metapod injured and in pain for twenty years, even though he could have healed him for free at a Pokémon Center.
- Berserk Button: He takes issue with being called old, insisting he's only 30.
- Didn't Think This Through: When he kidnapped Red's son, Todd, he accidentally threw the boy in front of a moving truck. He then dragged Todd to a warehouse and tied him up, but left a very obvious trail of blood all the way there.
- Epic Fail: He spent twenty years in a forest and only managed to catch a Metapod.
- Expy: His personality is very similar to Rusty's.
- Evil All Along: At first, it's ambiguous if Ralphie is just a terrible person or if he is just so stupid that he honestly doesn't realise what he is doing. Over the course of the series, though, it's pretty clear that while he's certainly stupid, he is fully aware that he broke the law by kidnapping Todd and that people are dying as a result of his actions, and just doesn't give a damn. When confronted with his complete incompetence as a trainer, Ralphie realizes he should focus on what he is truly good at. Killing people.
- Fatal Flaw: Ralphie is so obsessed with getting a rematch with Red that he neglected his whole life and Pokémon for the last twenty years, convincing himself he's Red's greatest rival while Red became the Pokémon Master of the World, a successful billionaire, and got married to a beautiful wife.
- Freudian Excuse: Being defeated by Red mentally broke him as a child, sending him into a life threatening spiral of depression that isolated him from his friends and family and destroyed his understanding of his own self-worth. Being mainly remembered in his hometown for peeing his pants after being beaten by Red probably didn't help either.
- Good Counterpart: Believe it or not, to Rusty. Most of what he causes is because of delusion, and depression, and, had Rusty not killed him, he would've pulled a HeelFace Turn. This is opposed to Rusty being a Villain Protagonist all throughout his adventure.
- Hair Today, Gone Tomorrow: Ralphie's balding and wears his hair in a comb-over.
- HeelFace Door-Slam: Actually does consider changing for the better while in prison. ...too bad Rusty's Perfect Bidoof kills him a few seconds later.
- Idiot Hero: While calling him a hero might be a stretch, Ralphie absolutely is an idiot. He didn't graduate High School because he spent most of his life in the forest (the diploma on his wall says GED APPLICANT), he only caught one Metapod before meeting Red and never caught anything else, is ignorant of all Pokémon beyond the 151 in his native region, and doesn't realize that he could have taken his Metapod to a Pokémon Center at any point in the last twenty years and gotten it healed for literally nothing.
- Insistent Terminology: Ralphie is the coach and Todd is the student ... even though Todd will be the one teaching Ralphie everything he knows, helping him practice, and guiding him with sage wisdom and experience. He also claims his Potty Failure is due to a medical condition he calls a feeble blatter.
- Jerkass: Very much so. He condescends to everyone and shows no concern for anyone other than himself.
- The Kindnapper: Kidnaps Red's son Todd so as to gain a re-match from him. Todd is so embarrassed by Ralphie's ineptitude that he agrees to train Ralphie out of pity.
- Lethally Stupid: His stupidity has led to an immeasurable amount of lives taken, and for a long time he refused to take responsibility for any of them. By the last episode he seems to have consciously recognized himself as a murderer.
- Loser Protagonist: In spades. He's unemployed, he never finished high school, and he still pees himself while claiming it's a medical condition.
- Manipulative Bastard: Guilt trips Detective Squirtle for the deaths he was never responsible for, so that Ralphie and Todd could escape on board of S.S. Anne.
- Never My Fault: All the murders he causes are not his fault. He rams two police cars, killing four cops and he blames Detective Squirtle for their deaths because the Pokémon brought them here to bust him in the first place.
- Older and Wiser: Averted. Ralphie thinks that he's the coach for Todd because he's older... even though Todd knows far more than him.
- Only a Flesh Wound: Seems to believe that all wounds can be ignored indefinitely. As shown when he refused to take his badly injured Metapod for twenty years. Or take Todd to a hospital or Pokémon Center despite having a bleeding head wound.
- Potty Failure: It's called a feeble bladder and it's medical!
- Redemption Equals Death: Right when Ralphie learns the error of his ways and decides to become a good person for real, he is unceremoniously killed by Rusty and Pefect Bidoof from Pokémon Rusty.
- Small Name, Big Ego: His defeat at Red's hands fundamentally broke his understanding of his own self-worth. He believes himself to be Red's greatest rival, despite Red outright stating the contrary.
- Unknown Rival: Ralphie is convinced he is Red's biggest and greatest rival for the last twenty years. However, this is all in his head as not only does everyone not know him except as the kid who peed his pants when Red defeated him, even Red himself doesn't know he exists.
- Unsympathetic Comedy Protagonist: The amount of redeeming qualities this protagonist has can be counted on one hand.
The hero of first generation of Pokémon. Twenty years after this he has been extremely successful. He also features in Pokémon Rusty.
- The Ace: He's a Pokémon Master, head of a large company, well-respected by everyone, and Happily Married.
- Babies Ever After: Red had two children.
- But for Me, It Was Tuesday: Ralphie is just some random bug catcher Red never spared a second thought.
- Happily Married: Red. When bragging about his life in a high school reunion, he states that he is married to a "super hot wife". Red even considers this to be his biggest accomplishment; even bigger than becoming Pokémon Master of the world and starting a wildly successful business.
- Irony: Had Todd created to be a child he loved as much as Pokémon, but has neglected him for ages.
- Humble Hero: Well, not totally. However, he does at least acknowledge those who helped him become the man he is today, with special thanks to his greatest rival... Blue.
- Laser-Guided Karma: Falling off the skyscraper thanks to Ralphe can be seen as this, considering how much of a neglectful parent he was to Todd.
- Made of Iron: Red survives being pushed off a skyscraper by Ralphie.
- Noodle Incident: Red at one point stood on Mount Silver for a year straight.
- Parental Neglect: Todd states Red wouldn't even notice if he were kidnapped, to his kidnapper.
- Rags to Riches: Red founded a multi-million dollar Master Ball company after becoming Pokémon Master of the world.
Red's son. He considers his father clueless and neglectful, and is already a talented Pokémon Trainer. He was kidnapped by Ralphie and is now coaching him to defeat Red.
- Artificial Human: Red reveals he was created by Bill using the DNA of a Garbodor, Mr. Mime, and a bit of Froakie to have a Child-type Pokémon he could love as much as actual Pokémon.
- Body Horror: Eating a Rare Candy causes him to evolve into a fleshy monstrosity.
- Blood-Splattered Innocents: At the end of "Bill's FU", he is visibly traumatized after watching Ralphie cut Bill in half with a teleportation machine.
- Butt-Monkey: Has replaced Metapod as the seriously injured companion that Ralphie refuses to get actual medical attention.
- Calling the Old Man Out: Todd finally stood up to Red and Ralphie and called both of them out on their delusions, selfishness and mistreatment of himself.
- The Dog Bites Back: During the finale, he chews out Red and Ralphie for their actions and gives both of them a cathartic slap to the face.
- LEGO Genetics: Todd is actually a Child-type Pokémon engineered by Red using a mixture of Mr. Mime, Garbodor, and Froakie DNA.
- Like Father, Like Son: Todd seems to have many traits in common with his father, such as being a highly skilled Pokémon Trainer and being ruthless in fights.
- Made of Iron: Survived getting run over by a moving truck, though his untreated and worsening head wound comes up in each episode thereafter.
- Mentor Archetype: He got talked into coaching Ralphie, mostly out of pity, though Ralphie insists he's Todd's coach purely because he's older.
- Parental Neglect: Claims his father doesn't care enough about him to know he's gone.
- There Is No Kill Like Overkill: Against Ralphie's completely useless and barely alive Metapod, Todd has his Charizard mega-evolve into Mega-Charizard Y to finish it off.
The only Pokémon that Ralphie owns. He has been severely injured ever since his battle twenty years ago, because Ralphie refused to heal him.
- And I Must Scream: He's spent the last twenty years without evolving to his Butterfree form or even receiving medical treatment. He's shown to be covered in bruises and scars. The only move he can use is STRUGGLE and damages himself with the recoil of this. The worst part is that Ralphie could have taken him to a Pokecenter and instantly healed him free of charge at any time during the last two decades, but didn't.
- Butt-Monkey: All of his appearances show him in intense pain.
- Bury Your Disabled: He gets fused with a human named Bill after they're thrown into a teleportation machine together, and then Ralphie slices this fusion in half — killing them both — by activating said machine a second time.
- Determinator: It wasn't taken to the Pokecenter for twenty years because Ralphie was convinced it didn't need healing, it needed payback! The Metapod itself did not agree
- Teleporter Accident: He ends up fused with Bill thanks to getting caught in a teleporter pod with him. They're mercifully killed when Ralphie accidentally activates it again while they're halfway out of the pod. Then they explode for good measure when Ralphie tries to recall Metapod.
A talking Squirtle who was trained by an experimental division to solve crimes. He is in charge of the case to track down Ralphie.
- Atrocious Alias: Commonly refers to himself as Dick Squirts. It isn't until the final episode he realizes why such a nickname makes people uncomfortable.
- Hardboiled Detective: Takes the persona of a stereotypical tough cop.
- Jerk with a Heart of Gold: Abrasive as he is, he is willing to listen to his fellow officers who have input on a case. He even apologizes to an officer he slapped after he realized he had good advice and hoped he did not discourage anyone else from contributing.
- Sadistic Choice: Was forced into one by Ralphie who gave the choices to let him escape on the ship so that he could give Todd medical attention or capture him and risk Todd's death.
