Sh'strians
Minute aliens from a distant dimension brought to Earth during a battle between Superman and Chemo (S No. 370, Apr 1982: "Better Vengeance Through Chemo-stry!"). The yellow-hued beings are adversely impacted by bacteria when enlarged to human-size and so find a home in a replica of Kandor in the Fortress of Solitude (S No. 371/1, May 1982: "Kandor Lives Again!").
