Martin Stein (Earth-Prime)

Martin Stein is the vigilante known as Firestorm and a founding member of the Legends of Tomorrow.

The Nuclear Man
On December 11, 2013, Martin Stein was hit with the Dark Matter wave created by the particle accelerator explosion. Stein and Ronnie Raymond then merged into one body through the Firestorm Matrix. They then operated as the vigilante known as "Firestorm" and assisted heroes of Earth after Cisco and "Wells" built the Quantum Splicer in order to split them into two bodies.

Legends of Tomorrow
In 2015, Stein was recruited by Rip Hunter and became a member of his team alongside Jefferson "Jax" Jackson, Stein's new partner as Firestorm. They then fought together during the Dominator Invasion as Firestorm.

On November 28, 2017, Stein was killed in action during the Nazi Invasion.

Former Powers

 * Firestorm Matrix Connection: When the S.T.A.R. Labs particle accelerator exploded, Stein's body was supercharged with Dark Matter. Due the presence of the Firestorm Matrix, Stein was merged with Ronnie Raymond and formed the nuclear-powered composite known as Firestorm. After the death of Ronnie, Stein started merging with Jefferson Jackson until his death in 2017.
 * Psychic Link: Stein and Ronnie (later Jefferson Jackson), were able to connect to each other through voices in their minds, allowing them to communicate.

Abilities
"Nobody knows how to fix the ship like I do. Except for maybe Ray and Jax. And Rip and Stein. I guess Behrad's not bad either."

 * Genius-level Intellect: Stein was the creator of the Firestorm Matrix, which was considered a giant leap in science and a great success to his experiment.
 * Master Physicist: Stein was a quantum physicist and studied complex physics concepts.
 * Expert Engineer: Stein was one of few engineers of the Waverider, a vehicle created years in the future.

Former Equipment

 * Firestorm Matrix: The matrix was one of Stein's greatest inventions, allowing him to merge with individuals as a nuclear-powered composite.
 * Firestorm Suit: As Firestorm, Stein (as Jefferson Jackson) wore a protective suit in order to conceal his and Jefferson's identity as a vigilante.
 * Quantum Splicer: The Quantum Splicer is a device created by Cisco Ramon and "Harrison Wells" to split Stein and Ronnie back to their respective bodies. The splicer was then continuously used by Stein as Firestorm in order to willingly split back to his body.
