Prefab problem...

I made my self a prefab character that is animated and is spawning from a array. Problem comes in when I start the game, the character mesh rotates forward 90 degrees.

The AI code:

 var speed = 5;
 var deer = 10;
 var tap = 100;
 var rotate;
 var target : Transform;
 var other : Transform;
 
 //Movement Script
 function Update () {
     var dir = (target.position - transform.position).normalized;
     var hit : RaycastHit;
     if(Physics.Raycast(transform.position, transform.forward, hit, 15)){
         if(hit.transform != transform){
         dir += hit.normal * 50;
         }
     }
 
     var leftR = transform.position;
     var rightR = transform.position;
     
     leftR.x -= 2;
     rightR.x += 2;
     
     if(Physics.Raycast(leftR, transform.forward, hit, 8)){
         if(hit.transform != transform){
         dir += hit.normal * 50;
         }
     }
     
     if(Physics.Raycast(rightR, transform.forward, hit, 8)){
         if(hit.transform != transform){
         dir += hit.normal * 50;
         }
     }
     
     var rot = Quaternion.LookRotation(dir);
     
     transform.rotation = Quaternion.Slerp(transform.rotation, rot, Time.deltaTime);
     transform.position += transform.forward * speed * Time.deltaTime;
     
 //Destroy Object at Destination
 
     if (other) {
         var dist = Vector3.Distance(other.position, transform.position);
             if(dist <= 5){
                 Destroy(this.gameObject);
             }
     }
     
 }   
 
 //Mouse Events
 function OnMouseEnter() {
     speed = 15;
     LevelController.Points += deer + 10;
 }
 
 function OnMouseExit () {
     speed = 5;
 }
 
 function OnMouseDown () {
     LevelController.Points += tap + 100;
     ChangeDirection();
 }
 
 //Random Direction Script
 function ChangeDirection() {
     rand = Random.Range(2,-2);
 
     switch(rand){
        case -2:
          rotate = -135;
        break;
 
        case -1:
          rotate = -45;
        break;
 
        case 1:
          rotate = 45;
        break;
 
        case 2:
          rotate = 135;
        break;
 
        default:
          rotate = 0;
        break;
        }
 
     if(rotate!=0){
        transform.Rotate(Vector3.up, rotate);
     }
 }
