History:
Shay Lamden, nicknamed King Shark by Patty Spivot, is a meta-human with the physical characteristics of a human and a shark. He was hired by Zoom to take out Earth-1's Flash, only to be brought down by Harry Wells and captured and imprisoned by A.R.G.U.S. Though Shay eventually escaped, he was defeated and re-captured again by Team Flash. Formerly, Shay acted as a type of "guard dog" at A.R.G.U.S. Though Shay eventually escaped again, he was defeated and re-captured a third time by Team Flash. Shay resurfaced yet again when Team Flash asked A.R.G.U.S. if he'd be willing to serve as a test subject in a trial with a meta-human cure they'd been working on, but Grodd attempted to mind-control him, causing him to suddenly run off before a decision could be made. Shortly thereafter, The Flash forced the cure into Shay, turning him human again. However, Shay volunteered to permanently turn back into King Shark in order to stop Grodd from taking over the city, also wishing to make for hurting so many people when he'd previously been King Shark. He was then returned to A.R.G.U.S. and relocated to a nicer tank, where he now resides peacefully under the care of the widow of his late Earth-1 doppelgänger.

Powers:
 After Shay was struck by the energy of the particle accelerator explosion on Earth-2, this altered his DNA and supercharged his cells and Shay became a meta-human with physical characteristics and abilities of both a human and a shark, augmenting his physiology into well-beyond peak human condition.  Due to his shark physiology; Shay's cells are regenerative in nature, thus allowing Shay to rapidly heal from extensive injuries. Even after losing his entire right hand, he fully regrew it in seconds.  Shay is able to sense the bio-electricity in living creatures, as a normal shark does to allow it to track fish, which allowed him to track down the Flash's powerful electrical signature throughout an entire city (although he claimed it was scent).  Shay can withstand very high levels of physical damage, as shown when he was shot multiple times by Patty, but sustained no damage, as the bullets ricocheted off of him. This was proven again when he was able to face off against A.R.G.U.S. agents and get shot at plenty of times and simply remark that guns and bullets can't hurt him. King Shark's durability is far beyond that of average humans as he was able to take several lightning bolts hurled by the Flash.  Shay is able to move at speeds far faster than normal humans. His superhuman strong legs allow him to run very fast on land, although he is much faster in the water, as he was able to swim at speeds comparable to the Flash. He still isn't as fast as Barry on land.  Due to his shark physiology; Shay is able to swim as fast as an actual shark; allowing him to move in water at speeds nearly equal to that of the Flash.  Shay has shown great physical strength when he effortlessly grabbed Barry and held him up with one hand, with Barry being helpless as Shay gripped his neck. He also showed greater levels of physical strength when he tore open the roof of the West house during another attempt to find the Flash. During his attack on the West house, King Shark was able to knock down the Flash while the latter was running at superhuman speed.  Due to the fact that Shay's mind is more animal-like as King Shark, he's immune to Grodd's psychic powers, which allow the latter to control most humans.  Due to his shark physiology; Shay is able to breathe while under water.   Shay's physical appearance is quite intimidating by itself; two A.R.G.U.S. agents were paralyzed with fear when they saw King Shark, which gave him enough time to kill them.  As King Shark, Shay is able to use his immense size and strength when fighting against his opponents. When he fought against Grodd, he was able to punch him multiple times and toss him with ease.  Shay is a skilled tactician as he was able to escape an A.R.G.U.S. holding tank by playing dead and track down the Flash using his superhuman senses.  Despite his large size, Shay was somehow able to sneak up on the Flash without being noticed by anyone.
