Aqua
was another original of mine.  I made this character
up in RPG's way back when I first made up Animal
Teen.  Animal Teen was able to copy some of his
powers to different people.  Since Animal Teen was
me I had my friends become other heroes.  Aqua,
Wings, and Animal Girl all became heroes.  Animal
Girl is the only one who didn't make it into the GDF
universe, as of yet.  Pretty much the whole history
has changed since the start.

A QUICK ORIGIN OF Aqua

His sister and Cliff plane had crashed on a remote
Island.  This island was the staging ground for Doctor
Dino.  They of course were captured and was gonna
be transformed into Dino Warriors.  Doctor Dino has
a device to force plains to crash on his island.  

Sonic Soldier, Earth Lord and Animal Teen pick up a
single from the crashing plane.  They get involved
and rescue Julie and Cliff.  During the rescue the
transformation process is interpreted and Animal
Teen gives part of his powers to Julie and Cliff
instead.

Cliff blames Animal Teen for making them into freaks
but his sister wants to join GDF.  To protect his sister
Aqua joins the GDF also.  Hoping one day he will pay
Animal Teen back for what he did to him and his
sister.

Aquas Powers

Amphibious Nature: Aqua, can breathe both water
and air.  Aqua can survive in Air as well as in the
water.

Enhanced Sight: His ability to see in the murky depths
of the ocean allows him exceptional night vision while
on land. He has claimed that his eyes are adapted to
see at 5,000 fathoms (or 30,000 feet below the
surface of the water).

Enhanced Hearing: several times more acute than
human capacity.   Only the Blue Whale has better
hearing then Aqua

Superhuman Strength: Aqua possesses superhuman
strength and can lift up to 100 tons when in the water
or recently out of the water. He can easily jump 5
stories in a single leap on land.  His strength would
appear somewhat dependent on how hydrated he is.

Superhuman Endurance: Aqua possesses strength
and stamina that allows him to swim up to 700 mph
for at least a 2 hour period without significant breaks
for rest or recuperation.

Superhuman Durability: Aqua enhanced physiology
enables him to withstand impacts that would kill and
ordinary human. He has been seen in ocean depths
as deep as 30,000 feet (5.68 miles) below the
surface of the water. That amount of pressure is
1500 times the normal atmospheres, which is enough
to turn an ordinary human into a smear of blood and
bone dust. He is completely durable against large fire
arms without being incapacitation. Regular bullets just
bounce off his chest.

Superhuman Speed: Said to be the fastest thing
underwater, he is capable of swimming at a
consistent speed of 700mph for several hours. Aqua
can travel at much faster speeds for short "sprints."

Marine Telepathy: Aqua has the ability to
communicate directly with sea life.  Aqua is also to
have shown he has minor telepathic skills with the
ability to read other peoples minds.  (I had this way
before aquaman showed any ability at this.)  

Sonar Location: A sonar power which allows Aqua to
detect things when underwater.  Aqua can use this
sonar-like sense to detect objects much as a dolphin
might.
