Why do I feel that Mako is the most likely to have children in avatar: Seven Havens? I don't know, I can imagine him married with three girls. Although it's most likely a reboot of the story but I'd like to know how they did in life.
Something that makes me very indignant is that in the fanfics they characterize Mako as having "problems with his teenage son" to begin with, Mako would have a good relationship with his children in general and at any stage of his life. Are they forgetting that Mako practically knows how to treat children and teenagers; I would even go so far as to say that he is an advocate for the rights of street children. An example of that would be his adventures in the avatar legends role-playing game. (They should adapt those stories to animation because they are very interesting).
Are they forgetting what we saw in his solo comic? Or the same Bolin's upbringing? Practically Mako is his father.
So yes, Mako would be a great father and would try very hard to be one and give the best to his children.
At the moment I imagine him as Tenzin with his children. Although it makes me laugh because he seems to get so desperate with them lol.
After going through a traumatic childhood; of course he is going to want a family and a new change. Plus I have no doubt that all of his children would resemble Bolin in personality and values.
I'm sorry but I had to bring it up.
