Martin Stein (Earth-Prime)

Professor Martin "Marty" Stein was a nuclear physicist and a half of the nuclear Metahuman, Firestorm.

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.

After Raymond's death, Jefferson Jackson became his successor and merged with Stein as the new Firestorm.

Legends of Tomorrow
In 2015, Stein, alongside Jefferson Jackson, Sara Lance, Mick Rory, Ray Palmer, Kendra Saunders, Carter Hall and Leonard Snart were recruited by Rip Hunter. They were them the founding members of the team known as the Legends of Tomorrow and defended the timeline.

In late 2017, Stein was excited about his grandson and asked Gideon to fabricate a unitard. He then sang Good Morning on his way to the bridge and confused Jefferson, who refused to accompany him. Stein turned to Ray, who was saddened by the song as it reminded him of his childhood friend Gumball. Eventually, Gideon accompanied Stein as he returned to his quarters.

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 Raymond, Stein started merging with Jefferson Jackson until his death in 2017.
 * Nucleokinesis: Firestorm produces a tremendous amount of nuclear energy via the atomic reactions in its body, allowing it to control and utilize the power to protect itself.
 * Nuclear Pyrokinesis: The nuclear energy from Firestorm often presents itself as a powerful flame.
 * Psychic Link: Stein and Raymond (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."

- Sara Lance


 * 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 physicist and studied complex physics concepts.
 * Engineering: Stein was one of few engineers of the Waverider, a time travelling vessel 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 and Jefferson Jackson wore a protective suit in order to conceal their identities as vigilantes.
 * Quantum Splicer: The Quantum Splicer is a device created by Cisco Ramon and "Harrison Wells" to split Stein and Raymond back to their respective bodies. The splicer was then continuously used by Stein as Firestorm in order to willingly split back to his body.
