18 Ana Lucia
Role: Bolshy, loud-mouthed ex-cop who crash lands on a weird desert island and tries to boss all the other survivors into doing things her way.
The painful truth: Even Lost‘s producers admit they got it wrong with Ana Lucia, and dumped her character after one season. All she did was moan and shout and pout and wave guns about, which ultimately leads to her accidentally shooting and killing Sharon. Finally Michael killed her, but only because he was first in the queue.
