Red Tornado

In Justice League of America, Vol. 1, #64 (August 1968), the Red Tornado shows up at the JSA's headquarters on Earth-Two, claiming to be the "original" Red Tornado—a woman from the 1940s named Ma Hunkel. The JSA is suspicious, but Red Tornado has all of Hunkel's memories. Morrow, however, has programmed the Red Tornado android to defeat the JSA (Red Tornado believes they are dead, not just comatose) and cover his tracks by making each murder appear to be an accident. Red Tornado suspects Morrow is behind the "deaths", and tracks him down. Morrow kills the Red Tornado with an energy weapon, but then realizes he needs the android for his next crime. He revives Red Tornado, and Red Tornado is on the verge of defeating him when Morrow flees through a dimensional portal to Earth-One. Morrow defeats the JLA, but by this time the Red Tornado has followed him to Earth-One and realized that Morrow isn't killing (just incapacitating). Red Tornado revives several JLA members, who then revive several JSA members, and together they defeat Morrow. The JSA then admits Red Tornado as a full member in gratitude.

In Justice League of America, Vol. 1, #72 (June 1969), Red Tornado arrives again on Earth-One, only to have the Justice League ignore him as they battle a gang known as the Gruesome Ghouls and the "Chtonic Demons" who've tricked the hapless magician, Marmaduke Mantick. Red Tornado saves the day, and in JLA #73 (August 1969), the JLA finally listens to him: A "living star" known as Aquarius has managed to wipe out the Earth-Two universe. Doctor Fate has managed to protect the JSA and Black Canary's husband, police detective Larry Lance, inside a magic bubble, but this was two weeks ago. In JLA #74 (September 1969), the JLA travels to Earth-Two, and learns that Dr. Fate's bubble is all that keeps the Earth-Two dimension from being wiped out. Aquarius forces the JSA to do battle against the JLA, but his hold over the JSA is broken when Larry Lance sacrifices himself to save Black Canary. Aquarius is tricked into entering an antimatter universe, where he is destroyed. Black Canary then travels to Earth-One and joins the JLA.

Red Tornado's feelings of insecurity and his sense that he has never been completely accepted by the JSA are magnified in Justice League of America Vol. 1, #82 (August 1970). Red Tornado is easily captured by the alien super-being known as Creator2. Creator2 wants to merge Earth-One and Earth-Two into a new paradise Earth of his own making, and uses Red Tornado (who has been in both dimensions) as the "anchor" for this effort. Creator2's servants incapacitate several JSA members, but the dimensional merging is already at play and several JLA members are also rendered comatose. The Earth-One Green Lantern and the Atom realize Red Tornado is in the clutches of Creator2. With the help of Spectre, Dr. Fate, Johnny Thunder, and Thunderbolt free Red Tornado and end the threat—although Spectre is presumed dead.

Red Tornado has his final mission with the JSA beginning in Justice League of America Vol. 1, #100 (August 1972). The JLA is being visited by the heroes Elongated Man, Metamorpho, Zatanna, and Wonder Woman when the JSA calls for help. Arriving on Earth-Two, the JLA discovers that the villain known as Nebula Man has created a planet-sized magic metal fist which is crushing Earth-Two. The heroes contact Oracle, a super-being with vast knowledge, who tell them that only the Seven Soldiers of Victory (SSV) have the power to defeat Nebula Man. But the SSV were scattered through time by Nebula Man, and now the JSA and JLA begin to rescue them. In JLA #101 (September 1972), readers discover that an old SSV opponent, Iron Hand, is behind Nebula Man's attack. While the rescue of the time-lost SSV members continues, Iron Hand attacks JLA's Wonder Woman at JSA headquarters. The story concludes in JLA #102 (October 1972), where the last of the Seven Soldiers are retrieved. The JSA and JLA learn that Wing, sidekick to the Crimson Avenger, died saving the SSV from Nebula Man by using a secret SSV weapon against him. JLA's Wonder Woman defeats Iron Hand, but his device controlling Nebula Man is smashed and now not even he can stop Earth-Two's destruction. After the SSV recreate their weapon, Red Tornado takes the device into orbit and detonates it.

The JLA and JSA believe Red Tornado is dead, but he is not. Instead, the explosion opened a dimensional rift and hurled him into the Earth-One universe. He eventually reveals himself to the JLA, who welcome him as a new member.
