That's very interesting.... choosing such a masculine name but then raising them genderfluid. Interesting choice.
Sylvester Apollo Bear is a neat name, very celebrity-appropriate.
I don't quite understand your logic about
Sylvester being "not something someone irl is called"....Sylvester is legitimate. It's a saint's name. There were 3 popes named
Sylvester. It's pretty old-fashioned, but plenty of people are called
Sylvester in real life.
