Red Kryptoniteis a key part of theSupermanmythos , but comic fans may not know thatShazamhas his own version , called Sivanium . It made only one appearance , in 1953’sCaptain Marvel Adventures # 150 , which was also the last issue of the graphic symbol ’s Fawcett - era adventures .

Red Kryptonite is a unique variant . Other sort , such as Green or Gold , can kill Superman or take by his powers , but Red Kryptonite can affect him in different ways ; sometimes it can turn him evil or reduce him to a child - alike state . Many of Superman ’s most freaky Silver Age adventures came under the influence of Red Kryptonite . Most recently , Red Kryptonite was revealedto have psycho - active property for not most species , Kryptonians in particular . While many paladin have a special failing , be it Green Kryptonite , or lead or flak , Red Kryptonite is particular in how unpredictable it can be . Once , however , Doctor Sivana discovered a special metal that affect Shazam the same way of life Red Kryptonite dissemble Superman .

In the story , title “ Captain Marvel and the World of Too Many Sivanas , ” by Otto Binder and C.C. Beck , Sivana fall upon a new mineral that he project to tackle for evil . He forces people nearby to toil in his mine , jab up the new metal . This draw the attending of Shazam ( then concern to as Captain Marvel ) . As he race to stop Sivana , he hear that Sivana has booby - immobilize the mines , and if Shazam come any closer , he will explode them and pop the people he has enslaved . Undaunted , he reverts to Billy Batson , but find that Sivana harnessed the new alloy , dubbed Sivanium , and use it as a molecular re - arranger . Shazam finds the former slaves of Sivana all now face like Sivana and are all evil . Shazam turns back into Billy Batson , and when he changes back later , the magical lighting is imbued with Sivanium — turning Shazam into an evil extra of Sivana , with all of Shazam ’s powers . The evil Shazam / Sivana hybrid proves too much for thereal Sivana , who must then impinge on a deal with the thaumaturgist to hold back him .

Sivanium ’s molecular rearrange properties put it in the same conference as Red Kryptonite . On many occasions , the substance would mutate Superman into some fantastical shape , be it a red devil or a caveman , and that is what happens to Shazam here . He becomes a duplicate of Sivana , and even exceeds the original . Part of the Silver Age Red Kryptonite stories was how Superman would get out of whatever predicament the nub put him in , and part of this story ’s appeal is watching Sivana and the wizard oeuvre together tostop the evil Shazam .

Red KryptoniteaffectsSupermanin unfounded and eldritch ways , and for one payoff , Shazamhad his own version , one that made him a greater threat than Sivana .
