It's not that they're unbeatable, it's that they're so good that only a few can beat them, including both players and pokemon/weapons. Of course, this pertains to Uber/OP. I'm not saying that anyone wielding an OP weapon is indestructible and invincible until they run out of ammo. I'm saying that it's just too good at what it does.
