Firestorm #100 (1990)

“Down in Flames” Written by John Ostrander, art/cover by Tom Mandrake.

Brimstone, the plasma giant, has taken control of the sun to turn the Earth into an inferno. Only Firestorm can stop him. With Firestorm trapped on Earth, someone will have to make the ultimate sacrifice to set him free; Martin Stein surrenders himself to the Firestorm Matrix to allow it to leave Earth and prevent Brimstone from destroying the Sun.

Plus, a special bonus for the FINAL ISSUE: Firestorm creators Gerry Conway and Al Milgrom return with a new sequence looking back at some of the Nuclear Man's early adventures. Also, special art from previous pencillers Joe Brozowski and Tom Grindberg.

Key book; first appearance of Firestorm (Stein), 54-page final issue. Near mint condition.
