Don't say that please. That is his deadname.

His birth-name was ''Scribbles'' (GIVEN by his mother (or father) ) but he decided to change his name to ''Ace'' (Scribbles was his birth-name/old name.)
Still his deadname, stop using it
that is literally a deadname.
That's what a deadname is and it's extremely rude to call someone by it
