[1] Created by Paul Gustavson, The Twister appeared in short stories in issues #1 to #7 of Blue Bolt Comics, volume two (June to December, 1941).
In 2009, he appeared in the Dynamite Entertainment miniseries Black Terror, which is part of the Project Superpowers line of comics; he then appeared in Project Superpowers: Chapter Two as an ally of the heroes.
He wasn't unchanged, however; he now had the power to harness the wind and generate and control whirlwinds, and he had super-strength.
[5] At some point after World War II, The Twister was captured and imprisoned in the mystical Urn of Pandora, along with scores of other heroes, by the misguided Fighting Yank.
Decades later, the Urn was broken and the heroes freed; Twister emerged with a new costume, whose constantly shifting appearance makes him look like a man-shaped tornado, but his powers seem to be unchanged.
