Mystery Analysts: Aquaman

Aquaman may not really have a city per se (I don't count Atlantis and Amnesty Bay seems like a small town that would only have mysteries to solve if Jessica Fletcher lived there), but I'm sure he needs Mystery Analysts as much as anyone.  Great guy, very powerful, awesome hair, but not a detective, so I'm sure he could use some help when confronted with mysteries and clues.

Q.E.D.

Fortunately, in his case there are some obvious candidates (omitting the Sea Devils, who deserve to have their own thing going on).

Sea Sleuth

Phineas Pike, a.k.a., the Sea Sleuth!

Well, it's right there in the name, isn't it? 

He's a detective who is also an expert in all matters maritime.  I even made a custom Heroclix figure of him and an able assistant for Aquaman he is.  

Kind of like original Alfred. Except Alfred was an incompetent, in poor shape, and an expert on absolutely nothing at all.  

Captain Mark Compass

A former Navy frogman, Mark Compass is a "noted nautical investigator". 

Are there any... NON-notable nautical investigators? One has to wonder.

A roving maritime troubleshoot and "ship's detective"? It's almost as if he was created to be one of Aquaman's Mystery Analysts.  

Besides, he's a snazzy dresser.

Esther Maris

I love Esther Maris and I don't care who knows it.  In short, she was Aquaman's "Patty Spivot"; the romantic interest who actually seemed suitable for and chemistry-full with the hero, but whom the hero abandons for his One True Love.

Pictured: chemistry.

But in addition to being a love interest for Aquaman, she was a science reporter, specializing in sea stories.

She's sharp, like a fishing hook.

Clearly, she handily fills the "investigator reporter" role in this group of Mystery Analysts.

Lorena Marquez

Lorena "Aquagirl" Marquez was part of the aborted "Sub Diego" storyline, which was how she got her ability to live underwater.  

How she got her fabulous fashion sense, I do not know.

She was never a detective, but she was Robin-ing for Aquaman during that time, so she definitely did investigating and crimefighting.  Nothing has been done with her since she was retconned away. But she could be brought back as perhaps another offspring of an Atlantean and an air breather, which would allow her access to both of Aquaman's domains.  

Erika Watson

She's the named police officer in Amnesty Bay and she and Arthur were schoolmates.

She's no Kaye Daye, BUT if Aquaman came up against a mystery, there is every likelihood he would consult the one police officer he seems to know.  

Cal Durham

A former Black Manta follower who turned over a new leaf, Cal's motivated to fight against injustice and has the ability to breathe underwater.  

I can easily imagine him doing a lot of "leg-work" for Aquaman both in and out of the sea, making him a reliable (if not stellar) choice for the Mystery Analysts.

And for the bonus round, a surprise pick:

A.J. Curry

A.J. Curry, a.k.a. "the Sword of Atlantis".  

I do not imagine the reworked version looking like this.

Naturally (and fortunately) this character was retconned away once Real Aquaman returned.  But a re-worked version of him might be an ideal aide.  No reason Arthur couldn't have a paternal cousin whom he trusts and who is some kind of littoral investigator.  House detective at a beach resort?  Ecological crimes investigator?  Just someone who solidly represents Aquaman's land-roots.
