Ep 22. Invincible

In season 2 episode 22 of The Flash (2014), titled "Invincible," Barry faces off against Zoom in a final showdown that will determine the fate of the multiverse. With the help of his friends and allies, including Cisco, Caitlin, and Wally, Barry must come up with a plan to stop Zoom once and for all and save the Earth from destruction.

As the episode begins, Barry is still reeling from the revelation that Zoom is actually his long-lost doppelganger, Hunter Zolomon. He's also mourning the loss of his father, Henry, who was murdered by Zoom in the previous episode. But he knows he can't give up, no matter how overwhelming the odds may seem.

Meanwhile, Zoom is busy taking over the world, using his speed to wreak havoc on Central City and beyond. He's also rounded up an army of metahumans to do his bidding, including the unstoppable Black Siren (a doppelganger of Laurel Lance from Arrow). With so much power at his disposal, it seems like there's no way for Barry to defeat him.

But Barry refuses to give up hope, even as Zoom's attacks grow more violent and destructive. He knows that he has a secret weapon on his side: Wally West, who has finally unlocked his own speedster abilities. With Wally's help, Barry hopes to have a fighting chance against Zoom.

As the two speedsters prepare to face off, they're interrupted by a surprising ally: Earth-2's Harrison Wells, who has come to help in any way he can. With his scientific knowledge and tactical expertise, Wells could be the key to stopping Zoom once and for all.

But even with all of this help, the final battle against Zoom won't be easy. The villain has grown more powerful than ever, and he's not afraid to use every dirty trick in the book to win. As Barry, Wally, and Wells face down Zoom and his army of metahumans, it will take all of their skills and courage to emerge victorious.

Ultimately, the fate of the multiverse hangs in the balance, and Barry must do everything in his power to save it. Will he be able to defeat Zoom and restore order to the world? Or will his greatest enemy prove to be invincible after all?
