Jesus Christ meets the two main criteria of being a zombie:
1) He came back from the dead
Acts 2:24
But God raised him from the dead, freeing him from the agony of death, because it was impossible for death to keep its hold on him
2) He encourages zombie like behavior
John 6:53
Jesus said to them, "I tell you the truth, unless you eat the flesh of the Son of Man and drink his blood, you have no life in you"
