The Flash's King Shark vs. Gorilla Grodd Declares Its Victor

SPOILER WARNING: This article contains major spoilers for "King Shark vs. Gorilla Grodd," the latest episode of The Flash.

The Flash's long-gestating showdown between King Shark and Gorilla Grodd has finally made its way to the small screen. In the aptly-titled "King Shark vs. Gorilla Grodd," the two DC monoliths went toe-to-toe, but there could only be one victor. At the end of the day, King Shark reigned supreme on behalf of Team Flash.

The episode introduced Dr. Tanya Lamden, a scientist who worked with A.R.G.U.S. to develop a device that enabled them to communicate with Shay Lamden, aka King Shark. The device went haywire after Gorilla Grodd escaped from A.R.G.U.S. custody, causing King Shark -- who had become rather peaceable since his last encounter with Team Flash -- to lash out. Cisco got caught up in the ensuing battle, which caused Barry to use a prototype of the metahuman cure on King Shark.

Fortunately for Cisco, the cure worked, but not for long. The team needed to develop a cure tailored to Shay in order to keep him human; if he transformed again, he would be stuck as a "shark" forever. As the STAR Labs team debated over their next course of action, Gorilla Grodd broke into the facility to use Lamden's neural device in the hopes it could boost his telepathy. It did just that, allowing Grodd to extend his control over the citizens of Central City.

Team Flash quickly ran out of time and options. As they struggled to figure out a way to stop Grodd without falling under his control, Shay volunteered to revert to King Shark and battle Grodd. Since his metahuman form is part-animal, Grodd cannot use telepathy on him, leaving him immune to Grodd's best weapon. Shay acknowledged that he would be stuck as King Shark forever, but hoped the selfless act would make up for the harm he had caused and protect Tanya, the woman he loves.

With that, Shay allowed himself to become King Shark once more. He immediately pursued Gorilla Grodd, and the two came to blows as Flash and XS lay paralyzed by Grodd's telepathy. They careened all over Central City center, until they hashed it out once-and-for-all on the streets. King Shark emerged victorious and plucked the device off of Grodd's forehead, placing it back on his own head to communicate with Tanya.

Unfortunately, Grodd's use of the device had a serious side effect. Though it was removed, its impact on Grodd continued, expanding the power of his telepathy. As a result, A.R.G.U.S. was forced to put Grodd in a medically-induced coma to prevent him from becoming a danger again in the future. King Shark also willingly returned to A.R.G.U.S., where he and Tanya continued their research on his condition.

Airing Tuesdays at 8 p.m. ET/PT on The CW, The Flash stars Grant Gustin, Candice Patton, Carlos Valdes, Danielle Panabaker, Tom Cavanaugh, Jesse L. Martin, Danielle Nicolet, Hartley Sawyer and Jessica Parker Kennedy.
