Wont destroy child-gameObjects

When I destroy my enemy i have called bomberman It only destroys the collider by the looks of it and I just cant collide with the object anymore.

So there is a script attached to enemies->bomberman which destroys the gameObject. I assumed it would destroy enemies-bomberman->bomberman and enemies->bomberman->bombermanparticles but it doesnt.

Can anyone help?

here is the script attached to bomberman.

 function OnCollisionEnter (hit : Collision){
 
 Debug.Log("Colliding with an object: " + hit.collider.gameObject.name);
 if(hit.collider.gameObject.name == "ball" || hit.collider.gameObject.name == "dbz_ball(Clone)"){
 damage += 1;
 }
 health = maxhealth - damage;
 
 redColor = damage/20;
 Debug.Log("health is: " + health);
 
 //Debug.Log("red color is: " + redColor);
 //enemyRenderer.renderer.material.color.r = redColor;
 //enemyRenderer.renderer.material.color.b = 0;
 
 //enemyRenderer.renderer.material.color.g = 0;
 
 var color : Color = new Color(redColor, 0.0f, 0.0f);
 enemyRenderer.renderer.material.color = color;
 
 audio.Play();
 
 if(health < 1){
 health = 0;
 var clone = Instantiate(explosion, transform.position, transform.rotation);
 Debug.Log("gameObject should be destroyed");
 
 Destroy(gameObject.transform);
 Destroy(gameObject.gameObject);
 Destroy(gameObject);
 
 Destroy(clone.gameObject, 2);
 }
 
 }
