Re-presenting Alex "Mastadon" Harris!

He's...not quite finished yet, but I should be able to type up some of the details later.
EDIT: Changed Alex to a Frenzied Berserker, since it fits his personality much better. His main thing in combat will be raging, punching his target twice, and bonus action grabbing them. I don't have the book in front of me ATM, so there might be some issues with that action plan, but the point is that he grabs people and punches them, or punches people before grabbing them. Either way, they likely end up grappled and punched, so it's all good.
EDIT 2: I may end up rebuilding Alex as a Barbarian/Fighter or pure Fighter, but the end result will still be a badass.
EDIT 3: No rebuilding, but some attribute points are shifting.
