Biologically impossible, but the guys producing (miraculously) children with human women always appealed to me, especially when the child appears more human-like rather than mutant-turtle. I've always wanted to write fanfiction on it, but was never quite sure how any of them would respond or what the later ramifications would be in that hypothetical situation. I was curious what would your personal opinion for the boys would be.
I see you anon’d this at darthempress as well, ARE MY METAS NOT ALSO THE BEST THING SINCE SLICED BREAD ANON, HUH? lol jk ;) ;) ;)
Okay the way I see it…
Raphael has no particular desire to have a child but if he found himself a father then he would step up and do his best at the job, both in terms of providing for them and being there for them. He does not have a lot of faith in his paternal capacity however. He would be a supportive and loving father and would encourage his child’s independence. I think he would be a great father, tbh, though he would question himself constantly. He would always be there.
Michelangelo would absolutely adore having children and would cheerfully be a stay at home dad. It would be a dream come true for him and definitely something he desires to round out his life. He would relish the opportunity and hope for a partner who shared his desire. He would be an adoring and doting dad, probably not disciplined enough though.
Leonardo would like to have children but only in a planned context within a committed relationship, after they had discussed it. He would not consider his life incomplete without children but he thinks they would enhance it, even as they would amp up his protective and obsessive instincts to all new levels. He would be very loving but extremely demanding - probably too disciplined.
Donatello I don’t see as having any particular desire for children though ultimately that might depend on who he’s with and how serious the relationship becomes. He wouldn’t want any surprises though he would take responsibility in that instance (I feel they all would, ultimately?). I think he would provide the most balance in terms of stability and would definitely be caring and gentle, but could run the same problems as always of getting caught up in his work and neglecting himself and those around him.
As for potential ramifications, gosh that would depend on so many factors. What verse is it in, what the environment is, who the mother is, how old they are and so on and so forth. I mean you have to place them in context and go from there.
