Wally West

Wally West was the Metahuman son of Joe West and the stepbrother of Iris West.

The Flash: Season 5
Wally West was as surprised as the rest when Nora Allen showed up at the baby shower of his sister. He remained on the background however when Barry Allen and the rest tried to take down Gridlock and instead discussed with his father what he should be doing, now that Mallus was defeated by him and the Legends. As Joe attempts to help him, it turns out Wally misses Jesse a great deal.

He and Caitlyn find out that Nora's body and blood is infused with Negative Tachyons and he raises after Barry and Nora to stop them from entering the Speedforce, but is to late. He stays behind with his father and discusses what he wants to do. When they discover the true subject of Amunet Black's heist, Wally, Barry and Nora are breached into the plane and they manage to take out the crew before being forced to vibrate the plane enough not to crashland it. After another discussion with his father, Wally decides to head off and travel again, once again leaving Central City.
