With the recent events of Luffy's family tree being revealed plenty of theories involving his Mother have been sprouting up. So I thought it'd be nice just to have a thread to keep these in instead of having multiple threads or by taking existing ones off topic.
Now, heres my theory, hear me out. You can call me crazy all you want after reading. Hina is apparently 32 years old. So 22 years ago when Gol D. Roger was executed she would have been 10, which would have made her 15 when Luffy was born. Now, having a child is unlikely at such ages but they happen quite often. So, yeah it's pretty unlikely but not impossible.
Say Hina ate her devil fruit at a young age similar to Robin and then joined the marines, her fruit gift giving her great benefits, and despite her age raised in rank (If Coby could do it with his normal human self, why not her with a capturing devil fruit powers). She could have then been put on a pursuit of a rising revolutionist threat in which (This is where my theory starts to get stupid and fall apart people) fell in love due to her young heart and by observing said being for some time. A upstaging marine investigating a rising revolutionist and thus during such becomes romantically involved with, offspringing a child.
Note impossible, but very unlikely. Hina would have a better chance at being Coby's mother, cause despite her light hair all her children were born with black. Theres also the problem with Ace and his age, which would have made Hina too young, but theres also the mystery to Ace's "Portgas" name.
Yeah, most likely Hina in no way can be related to Luffy, but I just wanted to put down a theory. Garp and Dragon were Luffy's Gramps and Pops so nothing is too unlikely.
I'm interested in others theories, cause there is by far better characters. Don't be afraid to state what you think.
