Found this name, what if Bell is short for this and this is his true name, based on the history of Bellerophon, it seems to fit Bell, and if Bell is to be a hero, who better to be named after
Is this assumption made based on the first four letters?
There is nothing similar to the legends about Bellerophon + it is not a great idea to associate greeks mythology with Danmachi. A lot of people wrote this already, but I'll repeat this - most of all heroes and gods in greeks mythology are real assholes and have nothing in common with the description of the HERO as it is known right now
Was only a though, but aren't many people already names after famous people in mythology, so this does have some base in it, it's not completely impossible, but I see your point
