The Black is an overworked single Father of Thousands

When the last stars died, a part of Alex—the man who was once Venom and now the King in Black—died with them. Godhood came with its curse: the pain of watching everything fade. Friends, family, entire worlds—gone. Even the stars, when he sought their light, flickered out, leaving only the cold and darkness Knull had always intended. The last of the Light was gone, and Venom’s realm became an empty void.With life now scarce, the remaining symbiote children had only one place left to go—inside their new host. Thousands of them, all absorbed into Alex, their voices whispering in his mind. But for all his power, there was nothing he or Venom could do but drift in the darkness. And so, in the end, Venom, Alex—the last living thing in the universe—closed his eyes.Until the silence shattered. A thousand voices screamed awake as Alex opened his eyes to an unfamiliar skyline—one of smog and neon lights. Alone no longer, the One in Black must now find his place in a world that still burns with life.Or: Venom outlives his universe and lands somewhere in Gotham, alongside his symbiote children(Or Author has minimal knowledge of batfam lore or Marvel lore and also sucks at summaries)

Alex is from Earth-2TWEI (a slight variant of both the king in black comics verse and the MCU), he's an original character-variant of venom, all rights go to marvel on venom but alex -the human itself- belongs to me, how venom/alex acts is all non-canon.
