Every Gym Leader in Pokemon Generation 4 (Sinnoh)

No two trainers in the Sinnoh League use two of the same species of Pokemon as each other. Single overlaps happen – Champion Cynthia and Gardenia both keep a Roserade – but a matching pair turns up nowhere across the eight Gym Leaders, the Elite Four and the Champion, and none of the three regional Leagues before it managed the same. It is the sort of constraint a player never notices and a designer cannot enforce by accident.

Rosters do get revised, and Sinnoh’s neighbours show the two usual ways of doing it. Kanto swapped people between generations, handing the Fuchsia Gym to Koga’s daughter Janine and Viridian to Blue, so eight Kanto Gym Leaders and the badges each one awards is a list that depends on which decade you ask about. Hoenn moved faster, which is why eight Hoenn Gym Leaders and the Sootopolis seat Emerald reassigned needs a version note: Wallace holds that Gym in Ruby and Sapphire, and in Emerald it belongs to Juan, his old instructor. Sinnoh did neither. Across all three of its Generation IV games, not one of the eight was ever replaced.

What follows runs in the order Diamond and Pearl set out, from a mining town in the southeast to a seafront city on the far eastern edge of the map. Three of the eight are not in their Gyms when a challenger arrives, which is a strange habit for a region to have and a stranger one for nobody to remark on.

Roark

The Oreburgh Gym was offered to somebody else first. Byron, who runs the Steel Gym on the far side of the region, asked a trainer named Riley to take the post, and Riley declined on the grounds that Byron’s own son should be considered first. The son was Roark.

Roark kept his day job regardless. He is the safety supervisor at the Oreburgh Mine, and when a challenger first walks into town he is at the bottom of it, so the opening move of a Sinnoh badge run is climbing into a working coal mine to fetch a man in a hard hat. His team is a level 12 Geodude, a level 12 Onix and a level 14 Cranidos, not one of them fully evolved. Cranidos is one of the fossil Pokemon built from real prehistoric animals, restored from a Skull Fossil that can only be dug out of the ground beneath Sinnoh, and the Oreburgh Mining Museum a short walk away does the restoring free of charge.

The animated series later gave him a backstory in which his father ran the Oreburgh Gym before him and left it to move to Canalave. In the games that never happens. What the games give Roark instead is stability: he is the only Sinnoh leader whose three Pokemon and their levels are identical in Diamond, Pearl and Platinum. Game Freak rebuilt half the region for the third version and left the first fight untouched.

Gardenia

“It’s not because I’m s-scared!” Gardenia says this in Eterna Forest, outside a derelict mansion called the Old Chateau, to a player who has not accused her of anything. She runs the Grass Gym in Eterna City, and she is frightened of Ghost-type Pokemon.

In Platinum she turns up at a villa in the Resort Area and asks, unprompted, what would happen if there were a Grass-type ghost – a combination that did not exist anywhere in the games until Generation VI, two generations later. The Pokemon Adventures manga sends her to that same haunted Chateau in her official capacity and reports that she apparently did not go, because she was scared of ghosts. Three continuities, one phobia.

Her Gym is a greenhouse maze in Diamond and Pearl, staffed by four women hidden among indoor trees. Platinum tore it out and rebuilt it around an enormous clock whose hands rotate one position every time a challenger beats a trainer, opening the way north once the larger hand reaches twelve. Two of her three Pokemon changed with the room. Her ace did not, and a Roserade stands at level 22 in both versions. In the summer of 2024 the mobile game Pokemon Masters EX paired her with Dhelmise, which is Ghost and Grass at the same time. The hypothetical arrived, and it arrived on her side.

Maylene

Four black belts guard the Veilstone Gym. They are brothers, they call themselves the Karate Quads, and they will tell a challenger they fight for LOVE, COURAGE, HOPE and TEARS. Behind them stands Maylene, who is smaller than all four.

The games say she does not appear to know her own strength and is not sure how she came to be a Gym Leader at all, which is not the sort of thing a league usually prints about its own staff. The official episode summary for Lost Leader Strategy! goes further: ever since she was rudely defeated by Paul, she’s lost all confidence in herself as a Gym Leader. No official source has ever published her age, so the familiar claim that she is the youngest leader in Sinnoh is an argument from elimination rather than a fact.

She trains anyway. In Platinum she walks Route 217 barefoot through falling snow and refuses to use Fly there, on the grounds that it would cheat her out of the exercise. At the postgame Battleground she explains that bare feet are healthier, on the grounds that Pokemon manage without shoes. Her Lucario there reaches level 66, a level above the strongest Pokemon any other rematch trainer brings to the same venue, and it is the only one of them not holding a Sitrus Berry.

Crasher Wake

The sign outside the Pastoria Gym does not so much give a name as a billing: Pastoria City Pokemon Gym, Leader: Crasher Wake, The Torrential Masked Master. The reference record calls him the one Gym Leader who introduces himself by a stage name rather than a real one,.

The English name is a pun twice over, and both halves are water. Crashing wave supplies the first; a wake is the spreading triangle a boat leaves behind it. The Japanese is a completely different joke – Maximum Mask, shortened to Maxi, assembled from the orchid genus Maxillaria and the word for a mask – and his Japanese leader title, Water Stream Maskman, is a third invention again.

Pastoria is built around a swamp, and the Great Marsh beside it inverts the Safari Zone rules the series had used everywhere else. Throwing mud at a wild Pokemon makes it harder to catch and less likely to bolt; bait does the reverse, softening it up and sending it running.

Crasher Wake’s own Fen Badge behaves strangely too. In Diamond and Pearl it unlocks Defog for use outside battle; in Platinum, the same Badge unlocks Surf instead. Gyms staffed by people with other careers eventually became a design principle, and eight Paldea Gym Leaders, most of them holding a second job now run a whole region on it. Crasher Wake was doing it in a mask.

Fantina

Everyone tells this one the same way, and everyone has it backwards. In Diamond and Pearl, Fantina is not in the Hearthome Gym when a challenger arrives. She appears outside the Super Contest Hall on the very first visit to the city, says “You may challenge me, but not yet! You must become much stronger. Then, you may challenge me!”, and leaves. She only turns up in her own Gym after the player has walked to Celestic Town and been handed HM03 Surf by Cynthia’s grandmother, which is why the received account has it that you need Surf to reach Fantina.

You do not. The old woman hands over the HM and adds, in the same breath, that to use Surf outside of battle, the Hearthome Gym Badge must first be obtained. That is Fantina’s own Badge. The move supposedly barring the way is inert until she has already been beaten, which makes the whole trip a progression flag wearing a costume.

She is a Ghost specialist who is not originally from Sinnoh, and the games never once say where she is from. Her Japanese name, Melissa, was chosen to mark her as an immigrant; the English version has her scattering French phrases through her dialogue, and the French version has her scattering English through hers. When her last Pokemon is nearly down she shouts “Never give up, never surrender!”, which is a line from Galaxy Quest.

Byron

Canalave Gym and Olivine Gym have a peculiarity in common: both are Steel-type, and both are the sixth Gym of their region. Byron holds the Sinnoh one, a four-storey stack of lifts and moving metal platforms that has to be ridden in a set sequence, with a man waiting at the top of it whose sign calls him The Man with the Steel Body. Olivine’s belongs to Jasmine, who spends Diamond, Pearl and Platinum in Sunyshore City telling anyone who asks that the place reminds her of home, what with the sea and the lighthouse, and who hands out no Sinnoh Badge whatsoever. She is one of eight Johto Gym Leaders and their own eight-badge circuit, not one of these.

Byron is Roark’s father, and the pair hold two different Sinnoh Gyms at the same time. The official Pokemon site puts it without ceremony: Byron battles with his brave Bastiodon, and Roark rumbles alongside Rampardos. Both father and son are big fossil fans! Bastiodon is restored from an Armor Fossil, and the only way to obtain one is to go underground and dig for it. Long after the Badge is won, Byron can be found alone in a cabin on Iron Island that appears to be his, where he hands over a Metal Coat and chides himself for still treating his son like a child. The son runs a Gym.

Candice

Thirty-one people live in Snowpoint City. It is the northernmost city in Sinnoh, and its walkable streets form an eight-pointed snowflake when the map is seen from above. Bicycles do not work there, on account of the snow. One of the thirty-one runs a Gym on the region’s badge circuit.

Candice takes the seventh Badge, and her Gym is essentially a slide. No route reaches her that does not involve skating helplessly across ice and smashing the snowballs in the way. The official Pokemon site calls the place a three-tier rink; the reference wiki describes the same building as four floors. Her team shifts between versions without shrinking. Diamond and Pearl give her a Snover, a Sneasel, a Medicham and an Abomasnow; Platinum keeps the Sneasel and the Abomasnow, brings in a Piloswine, and gives the last word to a Froslass at level 44.

According to Candice, the cold and the distance mean trainers hardly ever bother coming to Snowpoint, which leaves her with a great deal of free time. She fills some of it teaching an adult class at the local trainers’ school, where a friend of hers once kept a Glameow hidden in a shed round the back. The headmaster found out and let it stay.

Volkner

Nobody worth fighting had come to Sunyshore in a long while, and Volkner had begun thinking about abandoning the post to challenge the Elite Four instead. In the meantime he rebuilt his own Gym out of boredom, into a three-room puzzle whose main floor is gigantic gears and clockwork platforms.

The city paid for it. The overland road into Sunyshore is shut: a guard at Valor Lakefront turns everyone back from Route 222 until the player has settled matters with Dialga, Palkia or Giratina, because the city has lost its power and the games blame the Gym Leader’s renovations for it. The Gym’s exposed dynamos draw enough current that Sunyshore resurfaced its walkways as solar collectors to compensate. His Pokemon Masters EX profile makes the whole business sound like diligence: he renovates his Gym while waiting for worthy challengers.

Even at the end of the circuit he is somewhere else. Flint of the Elite Four, an old friend, plants himself in front of the Gym door and refuses to shift until the player has climbed the Vista Lighthouse and talked Volkner into coming back to work. The last Badge in Sinnoh is guarded by a man who had to be persuaded to attend.
