Hunt the Gold
He was mentioned by Ronnie Raymond to be in Gemcore City at the moment, the city where The Flash, Mari McCabe and he were heading to, following Captain Cold, Heat Wave and Diabullet.

He was knocked out by Diabullet when the latter wanted to know about Brotone and what it could be used for. He was woken up by Ronnie, whom he warns that Snart is not after a chest of gold, but after a chest of a far more valuable material. Ronnie reveals to have brought the Firestorm Matrix and they fuse into Firestorm.

Martin Stein and Ronnie were torn apart again and recovered from the battle they had. When Mari McCabe chased after Diabullet, Ronnie and Professor Stein decided to fuse again and help out, so they became Firestorm again. Later after the battle, Martin Stein decided to stay in Gemcore City.
