Considering that at Tier 1, all the Mag 7 companions had the same critical for Super, Mega, and Epic. At Tier 2, the super critical stayed the same and the Mega and Epic criticals changed. So I'm guessing that at Tier 3, each of the Mag 7 will have a different super, mega, and epic critical and I think Bat's Epic critical should go like this: Bat curls up into a ball (much like his Mega) and disappears into a cloud of ghastly smoke, then steps out the humanoid Bat Masterson (with hands and feet) in a suit (in our Witchdoctors' Colors) and shoots the mess out of the enemy (like how Billy does in his Super Critical, only more epic XD), Bat places the sparkshooters back in their holsters and morphs back into a bat.
