History Series / OceanGirl

* DoesNotLikeShoes: Neri, Mera and Kal all go barefoot. The first few times Neri went to ORCA the kids made her wear shoes, which she hated. By season four she was barefoot even when horse riding. Mera was happy enough in shoes, being raised in the Australian foster care system, but generally went barefoot on the island. Kal never wore shoes.

* EverythingsBetterWithPrincesses: [[spoiler:It turns out that Neri and Mera are the daughters of their planet's rulers. In Season 4 their mother is referred to as 'queen' and they are called 'princess' several times. There's also a rival princess.]]

* ParentalAbandonment: Unintentional for the most part. [[spoiler:Neri and Mera's father dies shortly after reaching Earth, and their mother is presumed-dead back on their own planet. She reappears at the very end of the show. Until then Jason's mother steps in.]]

* TheBully: Vanessa, to start with. She's overcompensating because she's tall and smart so people often make fun of her. Later, Mick. He's just a jerk, but as the son of the base commander he can get away with it [[spoiler: (it's also implied that his behaviour is hiding his learning disability)]]. Both have [[HeelFaceTurn heel face turns]] when faced with Neri.

* NobodyCanDie: Bad guys either do a [[HeelFaceTurn heel face turn]] or are captured and put in prison. Good guys might be injured, but the closest anyone has come to dying is [[spoiler:Kal - he absorbed harmful energy and was put in stasis for the trip back to his planet, where he would be healed. Also Neri in Season 4, for an episode or two.]]

* BigBad: Dr. Hellegren, a scientist spent three seasons chasing Neri [[spoiler:and Mera, almost ending all life on Earth before his [[HeelFaceTurn Heel Face Turn]].]]

* EvenEvilHasStandards: Shersheba, the BigBad of Season 4, may have been planning to invade Earth, but she considered the deadly virus created by her servant, Malakat, to be "monstrous." May also go to a point with the big bad in Season 3, who aims to take over the world, but stops short when he realises that he'd also be killing his daughter.

* TheBully: Vanessa, to start with. She's overcompensating because she's tall and smart so people often make fun of her. Later, Mick. He's just a jerk, but as the son of the base commander he can get away with it. Both have [[HeelFaceTurn heel face turns]] when faced with Neri.

* DisappearedDad: Jason and Brett's parents divorced just before the first series. Brett is fairly sanguine about this. Jason, not so much.

* MadScientistsBeautifulDaughter

* {{Mooks}}: UBRI keeps their mooks in blindingly white lifeguard swimsuits. PRAXIS is a whole organisation of [=MIBs=].

* NobodyCanDie: Bad guys either do a [[HeelFaceTurn heel face turn]] or are captured and put in prison. Good guys might be injured, but the closest anyone has come to dying is [[spoiler:Kal - he absorbed harmful energy and was put in stasis for the trip back to his planet, where he would be healed.]]
* NoNameGiven: Charley doesn't actually have a name. "Charley" is just what Neri calls him because it's her planet's word for "whale."

* ParentalAbandonment: Unintentional. [[spoiler:Neri and Mera's father dies shortly after reaching Earth, and their mother is presumed-dead back on their own planet. She reappears at the very end of the show. Until then Jason's mother steps in.]]

* QuicksandSucks: Brett gets caught in a 1st season episode.

* TheBet: "The Institute" has a variant of the prom type, with a [[SubvertedTrope subversion]]: A bunch of kids make a bet to see who can bring the ugliest, nerdiest date. [[{{Jerkass}} Mick]] charms Vanessa into going with him, but he doesn't develop any true feelings for her.

* NamesToRunAwayFromReallyFast: SubvertedTrope: despite a name like ''Hellegrin'', he is by and large a HarmlessVillain.

* TheOtherDarrin: Dr Bates' actress switched randomly between seasons 2 and 3.

* [[spoiler:AlienInvasion]]: [[spoiler:The expedition that stranded Neri, Mera, their father, and Kal on Earth was to assess the planet for possible colonisation as their own planet was slowly dying. The plan was for them to take over the oceans, as they are adapted for life underwater, which would minimise their interactions with humans. Neri's rival in Season 4 had other ideas, but luckily it turned out to be unnecessary.]]
* [[spoiler:AliensSpeakingEnglish]]: [[spoiler:Neri speaks pretty broken English and remembers only a few words of her own language. Kal, when released from stasis, speaks perfect if slightly stilted English. All other members of their race speak English. Justified for Neri and Kal, who were on a journey to assess Earth for possible colonisation, and for Mera, raised by foster families in Australia.]]

* [[spoiler:AwesomeMomentOfCrowning]]: [[spoiler:At the end of Season 4, which also turned out to be the end of the series, Neri is proclaimed Crown Princess and heir to her mother's throne. Mera, who has actually been attempting to rule the planet as regent, gets a little tiara thing.]]

* [[spoiler:EverythingsBetterWithPrincesses]]: [[spoiler:It turns out that Neri and Mera are the daughters of their planet's rulers. In Season 4 their mother is referred to as 'queen' and they are called 'princess' several times. There's also a rival princess.]]
* FriendToAllLivingThings: Neri

* GreenAesop
* [[spoiler:HumanAlien]]: [[spoiler:Neri (and all others of her race) look completely human. Neri's sister, Mera, spent years in the Australian foster system without anyone realising she wasn't human.]]

[[spoiler:Neri was an alien, survivor of a crash years before.]] Over the course of four seasons, she and her friends discovered her past and her role in protecting Earth.

* Zeerust: The first series mentions "Laserblades" and "vid-discs" as well as "Credits" as a form of currency. The third season has a couple of these mentions but drops them otherwise.
