SM had a kid with Lois Lane roughly 5-10 yrs ago comic book time. But it was SM & LL from pre N52 that came to the N52 Universe but hid from the world. But N52 SM was in love with WW but died in 2016 and therefore pre N52 SM took over for him, recently N52 SM was brought back to life but due to Myztilpilk manipulation were combined into 1 being with combined history but mostly from Pre N52 SM.
As for the Asian SM before N52 SM died he had developed a super-flare ability, a Chinese scientist tapped & absorbed 1 of SM SF in a machine in order to create china's own SM. This resulted in an Asian SM with lower lvl powers but similar to those of SM that the Asian SM can't completely control as of yet.
