- "You can eat or you can eat right. All it'll cost you is a little patience."
- —Omar to Clementine and AJ.
Nothing is known about Omar's life prior to or as the outbreak began. He may have been a student at the school. He may have had an interest in cooking back then, which could explain his role as the cook.
In the early days of the outbreak the teachers left Omar along with everyone else to fend for themselves. Marlon along with Brody took it upon themselves to keep the student safe. Omar took up the position of cooking for the group.
He is seen in the school yard, with Louis, preparing dinner for the school. Clementine and AJ can speak to them, and Omar says that the dinner is not ready yet. If they are spoken to four times, Omar will say that just because AJ is cute, doesn't mean to say that dinner will be ready any quicker. Later in the episode, he is seen when Clem confronts Marlon about the trade. When Clem appeals to Louis or Violet, he can be seen ganging up on Marlon with the rest of the school. He is shocked and horrified when AJ kills Marlon. It is still to be seen how he reacts to this later.
- Omar is described as a perfectionist by Louis, and apparently becomes grumpy for about a week if an ingredient is out of place in his dishes.
- You can speak to him four times. On the fourth time he will say that just because AJ is cute, doesn't mean dinner will be ready quicker. He also says that staring at it won't make it go any quicker either.
