Six who are never going to be a part of my "Aqua Force" either...

Neptunius was a "Shazam" type of answer to Aquavenger's Captain Marvel...?
Aquavenger (1971) was the type of hero that would have been great for a TV series; with the majority of dialogue scenes being out-of-costume ones.
Big Bang Comics' Human Sub must have been Sub-Mariner moonlighting during his release from Timely Comics or something... Didn't go so well.
The top two ladies are AQUAVIVA from the group "Iberia Inc." - she was seen in a most unique (as in "never gonna happen again") crossover in Marvel's "Avengers Forever", mainly due to artist Carlos Pacheco's involvement...
(Aquaviva is all that nerdy chicks such as Namorita, Marrina and others over at Marvel were made out to be - but are clearly not! The only true Marina is this one anyway! The Elementals' Fathom -not to be confused with M. Turner's Fathom- is another one envious of Aquaviva here, I'm sure...)
And the blue lady is "unknown" from planet AQUA - a misnomer in the order of Greenland and Iceland since it is a book about a planet deprived of the precious H2O... And people thought only uneducated analphabètes (illiterates) who roam the world (like the Norsemen did - just to ransack portuary towns) could reach such heights of absurdism... Not sure where this ''Aquapolis'' is, either...
Finally, at the top we have Captain High Liner... Uh, no, that's not it...  Call him "The Islander" and forget all about him already...!
(I'd rather have Captain Nemo onboard, quite frankly!)
The twin sharkeys are there for show only - enjoy! :)
