4. Bicycle Girl - The Walking Dead (2010)
The pilot episode of The Walking Dead had it all. But perhaps the most memorable moment was not brimming with crazed creatures trying to kill the ex-Sheriff hero but instead with the tragic moment Rick discovers the half eaten, crawling Zombie female cyclist who is so malnourished she's literally falling to pieces. She tries desperately to attack Rick but she never stood a chance. Even if he'd laid down on the grass beside her she was running on instinct alone. When Rick later goes back to put her out of her misery the moment is a truly sad one. This is the first time in the show we truly empathise with a Zombie which is why we think she's left such an impact on us despite only being on screen for a few moments. Bicycle Girl is a sad, sorry figure that reminds us exactly what extent the whole idea of the Zombie apocalypse will stretch to as food sources - aka us - begin to run short.
