What type of personality should The Sixteenth Doctor have?

Basically the title. Would you want her to be fun and bubbly? serious and brooding? clownish and unassuming?

I’d love it if Billie Piper went against any type casting and played a Doctor like Three/Six. A more theatrical, elegant Time Lord-ish incarnation. A part of me wants her to be more timid as well? We’ve gotten so many tall, dark, confident Doctors over the years it’d be nice to see a chance of pace, closest we got to this was 13 I think.

Most importantly, I’d want to let her show off more of her weird side. Make the role her own y’know?

Honestly, in a vacuum, I kinda love this casting? Getting a former pop star/actor, someone who seemingly doesn’t suit the role of The Doctor much and trying to make it work is really cool imo. And I think Billie Piper could do a great job with it.

How would you want Billie Piper to approach the role?
