D-d-d-double wrong!
If you are going to pick the worst characters fromg Geass, you'd have to choose the lesbian girl who has already been chosen, and Suzaku, because while he may have redeemed himself in the very end, the first 8/10s of the series still exists.

Also, Rock is awesome, especially once the Anime ends. he is just becoming awesome at that point. Before he was cool, in the end he was awesome, and then afterwards in the manga, he becomes amazing!
