who would like a bullet proof enemy!
the leader of a new race (ike only the Captain or wizard or oger)
the only way to damage is with magic(All supers, certain grenades, melee abilities)
this enemy would most prob wont regen health or even have a shield,
it would be an enemy u would have to avoid, ud have to kill all the other enemies while avoiding this enemy and use all ur supers and grenades to take this enemy out

So a sword to, that already exists since swords do not have bullets
