Oscar (The Walking Dead)

Oscar is a prisoner survivor who joins Rick's group in The Walking Dead. He makes his debut appearance in the Season 3 premiere alongside Axel, Tomas, Andrew, and Big Tiny. Unlike some of the other prisoners (namely Tomas and Andrew), Oscar is brave, honourable and much nicer, along with Axel and Big Tiny. At first, Rick and his group were distrusting of Oscar and Axel, but when they soon prove their loyalty by killing the hostile Andrew and clearing out the remaining walkers that Andrew had brought into the Prison as part of his attack, Oscar and Axel are finally accepted into the group. Both Oscar and Axel prove to be rather vital members to the group: Oscar for his strength and Axel for his mechanic skills. He dies in the Woodbury assault while trying to save Glenn and Maggie in the mid-season finale of Season 3.

Trivia

 * Oscar is the fourth prisoner survivor to die (and the last prisoner to die in the first half of Season 3).
 * Oscar is the only prisoner out of all five to enter (and die in) Woodbury and the only prisoner to die outside of the Prison.
 * Though they are best friends and look out for each other, Oscar and Axel have several differences:
 * While Oscar is African American, Axel is Caucasian American.
 * While Oscar is tall, brawny and physically strong, Axel is short, thin and physically weak.
 * While Oscar is brave, calm, quiet and serious, Axel is timid, excited, talkative and funny.
 * While Oscar is more competent in killing walkers and has killed a few (bad) people, Axel is somewhat capable in killing walkers and has never killed anyone.
 * While Oscar knows how to use guns and is not afraid to use them, Axel doesn't know how to use guns and is afraid of them.
 * While Oscar died outside the Prison, Axel died inside the Prison (both of them were killed by the Woodbury Army led by The Governor).
