Gelshark is the only figure released in the second wave of Transformers and is a highly decorative beast which is a Great White shark.  This figure is a re-paint of Hasbro’s Transmetals2 Cybershark and is an awesome colored beast.

The above photo shows Gelshark in Attack Mode with a double Missile Launcher in its mouth and Tail Anchor weapon.

BEAST MODE:  Gelshark has a myriad of colors but the most notable is blue, purple, gray, silver, and yellow.  His body has many sections that give a mechanical appearance with tubes, rivets, and the such.  These parts are painted with yellow, green, red, as well as silver and gray.  His gills are chromed, mouth is pink with jaws fixed in attack mode, and fins are blue and gray.

There isn't much in poseability in Beast Mode.  I really don't like the way the fins are connected to his gill region and should've been connected with a ball in socket joint vice port connection.  With its current connection Gelshark will not stand on its fins without separating the gill section from the body.  When this happens Gelshark just rests on his belly using rear fins and folded legs of the robot.

To transform Gelshark into Attack Mode is simple.  The first thing is to turn each gill section out and up which now exposes the gray parts of his fins facing forward.  Second step is to lift his upper jaw to expose the Missile Launcher (you can store the missiles here in either Beast or Attack Modes).  And finally, separate the two yellow fins from the upper tail fin by folding them downward creating the Tail Anchor.  The tail can rotate giving the appearance of a propeller with the use of a "dial" that's found on the left side of his body.

ROBOT MODE:  Transformation begins with the separation of the gill section by lifting upward.  Also lift the upper jaw which exposes the robots legs.  Pull the legs down which is connected to the inner section of his body.  You can now see how the lower jaw make up the feet which need to be separated.  Next step is to remove the Missile Launcher from the pelvic region that the legs are connected to.  This can be a little tough to remove but I found that if you use your thumb nail to pry one side of the posts it comes out quickly.  Now move the legs out of the way which should look like the shark is swallowing the robot.

Now its on to the tail section.  Slightly rotate the gill section upward so that its out of the way.  The cowlings (tail covers) can be separated by sticking your fingers underneath and thumbs on top and pulling outward.  Don't pull too hard, just enough to separate the cowlings from the body.  Now grab the dorsal fin  joint on top and pull downward to separate it from the back.  You should be able to see parts of the robots torso and head.  Now separate the tail anchor-arm from the other arm (you'll see the second arm's fist).

Various shots of Gelshark for your viewing pleasure!

The above photo shows Gelshark in Robot Mode.  He displayed with his double firing Missile Launcher (gun) as well as the Arm Anchor weapon.

Here is another weapon called the Lance Fin which combines both fins which connect to the top/bottom ports on his fist.

Gelshark's Spark Crystal is located on his torso in Robot Mode.

Here is a close up photo of his head showing his crooked snarl.

Now for the tough part.  You'll have to move the gill section many times so that it's out of the way when you move the arms in place.   Pull the legs down and snap into place at the base of his torso.  From this point on you'll have a lot of tweaking of various parts such as the gill section, tail cowlings, and arms so that you don't break any joints.  It'll probably take about half a page to describe how to get the rest into place so I'll just say that the result is identified in the photo above.  Sorry for the weak ending to GelShark's transformation but I'm sure someone has a better, easier way than what I have tried.

I really like both modes and especially his neat little Arm Anchor weapon gimmick.  Overall it's a decent looking figure minus the difficulty in transformation.
