Chibiusa

Has to be the most annoying character ever. If I were Usagi I would go get my tubes tied so that she could never be born. I was just watching and I love how - after stealing Usagi's broach and brushing off the Senshi who just saved her life - she calls Usagi self-centered, irresponsible, and spoiled. Usagi is quite irresponsible at times but none so much as Chibiusa and you can't call a girl who sacrifices her life to save another selfish. As for spoiled, the closest Usagi gets us apparently spoiling her own daughter in the future. Seriously, I know she's a kid but I cannot stand Chibiusa.
