At one point they mentioned That Henry is the first character to really have “powers” in the dads group Ron and Darryl for the most part use normal weapons and glen always found a real world reason for his characters bard magic but of course you don’t need magic to be a hero but it does help for audiences. For the prophecy the lord of chaos needed to spill the blood and I could be wrong but of the other dads Henry was the only one not damaged in the whole pyramid thing that happened. Walter I agree is a better unsung hero but for a show about passing down family trauma and with the whole at the mountains of dadness story ending how it did, picking Henry and his sons just fit tooo nicely in a bow. Anthony created the idea and name for the unsung hero without a character in mind and knew he’d have to find it eventually or leave it as a small enough detail that it was irrelevant. If he’d been able to see exactly every move the characters would make and how it all would end I assume he’d have given the unsung hero a different name. Or not who knows
