Depends on the names, some names are normal, every day names (Terra, Vincent, Yuna, Cid etc), I wouldn't go with anything REALLY out there like Bartz (Bart is fine but Bartz? No, don't think so), Zell, Ashelia (thats just a bit too obscure for my liking), Cloud, Squall etc.
Some characters you can get away with naming your child after as they work in real life but if you go too obscure you are looking at your child being picked on because of it and given how kids are these days with bullying you are going to have one really upset kid because of your bad parenting skills and, if it is really bad, possible suicide due to your actions also.
So before naming your child after any Final Fantasy character stop and think if you want your child to be bullied, if it is a no then you obviously need a new name.
In all honesty here, I don't know if I should skuld you or make your day worst.
Anyway, its up to him, not you, also, I name my child based from a video game, Dead or Alive.
Her name is Ayane Revrem Mythral, and she is just fine and never got bullied as far as i'm concern when i'm around, an when she is/was she told me about how she kick't the bully's a**. I tought her Martial Arts, an how to use it for good.
I raise my kids on how I see fit, an to prepare them for the world.
An also you don't know that yet if this guy going to be a "Bad" parent.
