    The Guardians 

The Guardians as a whole.

  • Secret Keeper: They know about something evil being contained in Lemuria, and are concerned about what Proteus wants with it.


Voiced by: Lee Tockar
  • Eccentric Mentor: Gives the Nektons clues in the form of riddles rather than being straightforward with them.
  • Really 700 Years Old: He's an original Lemurian from when the kingdom fell. In fact, he was the brother of the final queen of the kingdom.
  • Secret Keeper: He often keeps a lot of things from the Nektons. It can be very vexing for them.
  • Technologically Blind Elders: For all his wisdom, Nereus is completely lost when it comes to operating technology.

    The Dark Orca Crew 

The Crew as a whole.

  • Evil Counterpart: To the Nektons.
  • In the Blood:
    Finn: It's the family business, you know? Some kids become doctors or accountants. I have to become a pirate.
  • Submarine Pirates
  • The Alleged Submarine: The Dark Orca is in a constant state of disrepair, which is commented on in several different episodes.
  • The Pirates Who Don't Do Anything: They're really only shown attacking shipping in their introductory episode. In subsequent appearances they're mostly just looking for sunken treasure, coming into conflict with the Nektons only because they just want these historical artifacts for their monetary value rather than preserving them.

Captain Hammerhead

Voiced by: Michael Dobson
  • Bad Boss
  • Beard of Evil: A big bushy black beard, befitting a pirate captain.
  • The Captain: Of the Dark Orca.
  • Even Evil Has Loved Ones: He clearly cares for his children, even once going out of his way to retrieve a memento of Madeline's late mother. He even weaponizes this, using his concern for Madeline's safety to get her onto the Aronnax in order to steal the Chronicle of the Deep.
  • Evil Cannot Comprehend Good: He doesn't get why the Nektons don't have missiles in their submarine, for without them the Nektons can't attack and steal.
  • Seadog Beard: Sports a long bushy beard.
  • Talk Like a Pirate: Even though it's a modern setting, Hammerhead speaks with the archetypal West Country accent.

    Other Characters 

Professor Fiction

Voiced by: James Higuchi
  • Absent-Minded Professor: Undeniably brilliant, also undeniably scatterbrained.
  • Keet: Rivals Ant for sheer enthusiasm.
  • Mad Scientist: Develops most of the tech used by the Nektons, in addition to being rather eccentric.

Devil Daniels

Voiced by: Trevor Devall


Voiced by: Brian Drummond
  • Child Hater: He finds them annoying. Especially Ant.
  • Information Broker: Will occasionally comes to him for information, as does Captain Hammerhead.
  • Insufferable Genius: He's smarter than you, and not afraid to let you know it.
  • Playing Both Sides: Has no compunctions about selling a treasure map to multiple parties. He's just doubled his payday.

Alpheus Benthos

Voiced by: Andrew Francis
  • A Pupil Of Mine Until He Turned Evil: He was a previous apprentice of Nereus, until he decided he wanted to use the power of Doreus' Scepter to Take Over the World.
  • Big Bad: Of the second season.
  • Evil Plan: Alpheus' plan is to obtain the Scepter of Queen Doreus and use it to awaken all the Monumentals, including The Terror, and effectively use them to threaten all the nations of the world into achieving peace.
  • Smug Snake: Even when his plans go awry, and/or he's outwitted, his expression always has a very smug look about it.
  • You Gotta Have Blue Hair
