Harry Potter for the headcanon thing!
when he was seven or eight, harry made a list of all the names he’d change his name to if he had the chance. harry was the name of a spindly boy who lived in a cupboard under stairs and tripped over too-large sneakers and got bullied every day. he didn’t like the name harry. he wanted something more regal, something that would at least make him seem more powerful because maybe then he’d grow up and be that powerful.
included on his list were some normal-ish names, like charles, henry, and arthur; gideon, which he’d once heard as the name of a teenager a few years above him who was kind to everyone; and a couple of funny sounding names he’d pulled out of a star chart, like rigel and sirius.
