Barron Sharpe

[Here's Barron, looking... basically exactly like himself, except in a rather smart suit with his hair slicked back.]

Mysterio, master of memory, welcomes you to Gotham. [Barron smiles, showing way too many teeth.] I will take away your troubles. I will grant you more years with your young ones. I will draw the pain that has seared itself deep within you from you, in a way that will be so painless that you will forever wonder what had troubled you so.

[He pauses, dramatically.] You need merely to ask. Mysterio rather likes visitors. My price is secrets, impossible things and a little of your past. [A beat, then deadpan.] And cash.

[Barron's a supervillian with his normal power, which is basically to change/add/remove memories. He's basically just your normal working supervillian (including the lapsing into third person) who hasn't quite made it into the big leagues and occasionally gets punched in the face by Batman.]
