Dawg, he is amazing T.T
I like the sound of his voice and he's interesting. Idk about him just using guns though. It gets old fast with a character who only shoots pistols at someone. Even Jax and Stryker had more things up their sleeve despite him being a cooler character.
I don't understand the fatality as well. So does the "Outworld Sand" contained in that small ball have the ability to manipulate itself and replicate?
That would be the only logical explanation for all that sand to pour out.
