Firestorm (DC Universe, Jason Rusch)
When a mortally wounded Firestorm (Ronnie Raymond) fell from the sky, he cascaded Jason Rusch in atomic energies. Jason thus bonded with the "Firestorm Matrix" and gained the ability to fuse his body with others. Eventually, Jason merged with professor Martin Stein, original host of the Firestorm Matrix to carry on the mantle and mission of Firestorm.
