I have a few little ideas (theories?) of what would have happened to Fink:
If Lazerblast had stayed a hero Fink would have been found by Carol or Lazerblast during a mission and they both adopted the little girl. Making her childhood a happy and loved filled one, growing strong or pursuing her passions earlier.
Fink would eventually be found by Boxman who would adopt the little girl and she'd learn tp grow and help her new family prosper due to her intelligence.
A villian, hero or even a civilian may have found the little mouse girl and adopted the little girl, making her either family or minion.
Omg imagine laserblast raising fink to become a sidekick instead of a minion
OR boxman struggling to raise her bc he's not used to taking care of an organic child
