2 Prefabs are fighting each other but both are taking damage when one is hit.

Im making an Gladiator Manager Game but when 2 gladiator are fighting they both take damage when 1 get hit. they are both a clone of the same prefab and im dealing with damage with a trigger collider to the send damage through a "getcomponent" command.

Here is the code:

 public int state;
 private Animator anim;
 private Rigidbody2D rb;
 private GameObject closestTarget;
