Variants-
Dead eye - Inspired by the ability given to John Marston in red dead redemption, once per round you can trigger this ability. Similair to reptiles "nimble" variant, this will cause the opponents speed to be reduced, while Erron Black will move quicker, but can only use projectile attacks (gains air revolver shot and low revolver shot) lasts for 8 seconds or until Erron has used 6 shots from the revolver (6 bullets in chamber, is aiming down sight of 1 revolver during this ability not hip firing 2). You will be able to tell this variant apart from the others appearance wise through Erron wearing an eye patch over 1 eye.
Bandit - Erron Black will gain a lasso placed around his hip area and a riffle on his back. New moves will allow throwing the lasso around the opponent, leaving them vulnerable for a free hit/combo. Can also wrap the lasso around opponents foot from a distance, pulling them to the ground. Riffle gives new projectile attack with air juggline properties and also can be used in combo strings as a bat. New throw involves hitting the butt of the rifle into the opponents nose.
Trigger finger - In Errons other variants, revolver projectile is only 2 shots (1 from each revolver hip-fired) but in trigger finger he shoots 4 (1 from left, 1 from right, spinning the left chamber while shooting the right) and ex revolver shot is 12 shots (both revolvers fired very quickly). Also gains the ability to time shots (like stryker in MK9) and cancel the shot by dashing either way.
What I think erron will play like.
