Does Ikue Ohtani make major dough for doing Pikachu? She has other roles of course like Chopper, and Gash Bell back in the day, but I wonder if she's basically set for life.

Yeah, it happened when she went on maternity leave back in 2006.

I thought in that case, didn't they get someone else to voice Pikachu? I remember some of the other Pokemon she voiced (Mime Jr.?), I think someone took over for her. Or maybe I'm thinking of the time the girl who did Mimirol's voice left?
