Roman and the Brothers

Roman created Lolololka, who destroyed worlds, and for this Roman was exiled somewhere (something like that).
There were four of Roman's creations: Lololoshka, Weevilka, Nonoknife, and JDH/John. They weren't considered brothers, but they were created by the same person within a week of each other, and the four of them came to consider themselves brothers. Because they were so destructive to worlds, it was decided to send them to different realities.
The gods who exiled them hoped they wouldn't remember each other or Roman. But the brothers remembered everything perfectly well and decided to act out scenes in their own realities, pretending to know nothing about the other realities. They were similar to each other, but each had something more than the others. For example:
• Lololoshka was kinder.
• Vivivilka was more evil.
• Nonoknife was calmer.
• JDH/John was more mischievous.
They didn't listen to anyone except Roman.
It turns out that Lololoshka is the eldest, then comes Vivivilka, Nononozhik and the youngest was JDH/John.
Roma watched over his creations in different worlds, and if under some circumstances his creations could not cope, he helped.
The brothers don’t know that Roman helped them and don’t even know where he is.
