In Generations I, II, III, and VII, the Cerulean Gym is designed like an indoor swimming pool, with platforms above the water for the player to walk on. In Generation IV, the Gym consists of a large pool roped off into lanes with certain parts of the area circling the pool blocked. There are no puzzles to solve in this Gym.
In Generations II and IV, Misty isn't initially at the Gym. After the Team Rocket Grunt that stole the Machine Part from the Kanto Power Plant is encountered at the Gym, she can be found at Cerulean Cape, having a date with her boyfriend. After her boyfriend is scared away by the player's arrival, Misty will at first be angry at the player for ruining her date, but will then return to the Gym, allowing it to be challenged.
In Pokémon: Let's Go, Pikachu! and Let's Go, Eevee!, the player must have a Pokémon that is at level 15 or higher in their party in order to be allowed to challenge the Gym. However, they are not required to use this Pokémon at the Gym if they so choose.

Cerulean Gym in its latest appearance in the anime
Cerulean Gym's battlefield in its latest appearance
Cerulean Gym's aquarium
Cerulean Gym has appeared in multiple episodes of the anime. In its original design, the building was a dome-shaped, brightly colored Gym with a gigantic painting of a Dewgong on top of it. On the inside, the Gym was seen being equipped with a large aquarium and a swimming pool. In Pokémon the Series: Sun & Moon, the Gym seemed to have gone through a massive redesign in-between appearances, both on the exterior and the interior. For example, the battlefield is now a stone field, which can be retracted into the floor and filled with water to form a water field, suitable for the Gym's Water-type Pokémon.
It first appeared in The Water Flowers of Cerulean City. Ash was heading there so he could earn his Cascade Badge. Misty kept telling him not to go to Cerulean, and he soon discovered why she had tried to stop him; her three sisters, Violet, Lily, and Daisy, were the Gym Leaders, who didn't care much about battling and had instead turned the battlefield into a performance hall for their water acrobatics shows. Incapable of giving Ash a proper Gym battle, due their recent defeats against Gary and two other Pallet TownTrainers, they were about to simply give Ash a free Cascade Badge, when Misty intervened. She challenged Ash to a battle in her capacity as an official Gym Leader, but the battle was interrupted by Team Rocket trying to steal the Gym's Pokémon with a giant vacuum cleaner, only to be defeated by Ash and be sent flying by their own machine. In the end, Daisy gave Ash a Cascade Badge for protecting the Gym, also saying that if Ash's Pikachu hadn't refused to battle, Misty's Water Pokémon wouldn't have stood a chance of winning.
The Gym's next appearance was in The Misty Mermaid. While the group was on the way to the Viridian Gym, Misty's Horsea became sick. Realizing the Gym was nearby, Misty decided to go and see if they could make Horsea feel better there. At the Gym, Misty's sisters told her that they had set up an underwater balette and given Misty the main role without asking her first. With the first performance due to be held the following day, Misty was left with no choice but to accept the role. During the performance, Team Rocket attacked and tried to steal the Gym's Pokémon again. This time, they were defeated by the Gym's Seel, which evolved into a Dewgong to protect the Gym. Afterwards, Misty's sisters asked Misty to leave her Horsea and Starmie at the Gym for their future performances, which she reluctantly accepted. She also tried to force her Psyduck on them, but they refused.
In Just Add Water, while traveling through Johto, Ash and his friends met a Water-type Trainer named Dorian, who had visited the Cerulean Gym and met Misty's sisters multiple times, wishing to make his own unofficial Gym, the Coastline Gym, as widely known as the Cerulean Gym.
In Gotta Catch Ya Later!, Misty received a call from her sisters, informing her that they had won an around-the-world trip and were giving their Cerulean Gym Leader status to her so that she could take care of the Gym in their absence.
The Gym made a brief flashback appearance in Judgment Day!. Ash and his friends met a referee-in-training named Jimmy, who told them how he had once passed by the Cerulean Gym, when Daisy had come up to him and asked him to help clean up the Gym's pool. Jimmy had accepted the request, and once he and his Pokémon had done their work, Daisy had given him a free Cascade Badge. Jimmy also mentioned that Misty hadn't been at the Gym at the time to battle him.
The Gym reappeared hundreds of episodes later in Alola, Kanto! and When Regions Collide!, where Ash and his classmates from Alola visited it during an extracurricular lesson, guided by Brock and Misty. After giving a brief summary to Ash's classmates about how Gyms, Badges, and the Pokémon League work in Kanto, the group was offered to experience a Gym battle. First Mallow and Lana took on Misty, after which Sophocles and Lillie battled against Brock. After both of these battles had been called off with no clear winner, Kiawe requested to have a serious battle against Brock, while Ash issued a similar challenge to Misty. During the battle between Kiawe's Turtonator and Brock's Steelix, the former Pewter Gym Leader Mega Evolved his Pokémon as a response to Kiawe's decision to use his Z-Move. Although Turtonator's Inferno Overdrive dealt heavy damage on Mega Steelix, it was unable to deal the finishing blow, allowing Brock to win the battle with his next attack. In the following battle between Ash's Pikachu and Misty's Gyarados, the Cerulean Gym Leader also demonstrated her ability to use Mega Evolution. However, unlike Kiawe, Ash was able to use his own Z-Move, Gigavolt Havoc, to defeat his Mega Evolved opponent. Before Ash and his classmates headed back to Alola, Brock and Misty gave each of them a replica Badge to commemorate their battles.
In A Fated Face-Off!, Misty revealed that she had left the Cerulean Gym in order to set off on a new journey, inspired to do so after seeing Ash's battle against Leon and leaving the Gym in her sisters' care. She returned to the Gym in The Rainbow and the Pokémon Master!.
Dewgong first appeared as a Seel, holding out the Cascade Badge, when Ash was about to challenge the Sensational Sisters. Later, Seel was one of the Pokémon performing in a play hosted by the sisters. It evolved into a Dewgong while battling Jessie's Arbok.
Lily has her own Goldeen as her only known Pokémon. She sent it out briefly to show Ash that it was the only Pokémon that she had left after she and her two other sisters were beaten by the three other Trainers from Pallet Town.
Cerulean Gym was briefly seen in File 2: Cubone, when Red recalled of having a tough battle with Misty, but eventually emerging victorious, thus earning the Cascade Badge.
The Cerulean Gym appeared in Play Misty For Me. After defeating Brock rather easily, Ash was confident of his abilities, and headed to Cerulean City in order win his second Badge. At the Gym, Ash met Daisy, Lily, and Violet, who briefly talked about which one of them would battle Ash, until Misty arrived, declaring that she'd battle him.
At the Gym's water battlefield, Misty revealed her Pokémon to be Gyarados, which proceeded to snatch away Ash's hat. Misty declared that if Ash would be able to get his hat back from her, she'd give him the Cascade Badge. With Pikachu being too scared of Gyarados, Fearow being asleep, Pidgeotto being away, and Metapod only being capable of using Harden, Ash's chances for succeeding in the given task seemed nonexistent. However, Metapod then suddenly evolved into Butterfree, allowing Ash to put Gyarados asleep with Butterfree's Sleep Powder. Although Pikachu was now willing to move, Misty distracted the Electric Mouse with a rice ball before it could get the hat back. Ash countered by throwing a soy sauce-covered dumpling at Misty, causing his dumpling-loving Fearow to snatch the hat away from her. As promised, Misty's sisters then rewarded Ash with the Cascade Badge, despite Misty trying to protest that Ash's victory was a fluke.
The Cerulean Gym appeared in Suddenly Starmie, where Red and Misty trained together at the Gym for a few days to improve their skills in order to fight Team Rocket. After the training was complete, Misty gave Red a Cascade Badge.
The Cerulean Gym appeared in Obtain the Moon Stone!!, where Red and his Pokémon fought Misty in order to obtain the Moon Stone she had with her. In the manga, Cerulean Gym is depicted in a very traditional Japanese architectural style.
The Cerulean Gym appeared in Cerulean City, where Satoshi went to the Gym to challenge Misty. However, since Satoshi and his Pikachu had trouble swimming in the Gym's pool, they had to practice for a while in order to learn how to swim. Soon after, the Gym was attacked by a Team Rocket Grunt using a Gyarados, but Satoshi defeated the Grunt, driving him away. As a reward for saving the Gym, Misty gave Satoshi a Cascade Badge. She also gave Satoshi her Seel before the young Trainer left.
In the TCG
The Cerulean Gym was featured in the TCG as both a Japan exclusive Theme Deck and as a card. The following is a list of cards mentioning or featuring Cerulean City Gym in the Pokémon Trading Card Game.

In the English Generation I games, the Gym guide here refers to Pokémon of the Grass type as "plant Pokémon". In the English versions of Pokémon FireRed and LeafGreen, he instead mentions "Grass-type Pokémon". In the Japanese versions of the Generation I games and FireRed and LeafGreen, he mentions the Grass type itself, calling it the "Plant type" (Japanese: しょくぶつタイプ).
In Generation II, it is possible for the player to pick up the Machine Part from the Gym before learning of its location from the Team Rocket Grunt on Route 24. This is no longer the case in Generation IV, where the player must defeat the Grunt in a battle in order to make the Machine Part obtainable.
