Fresh out of his egg, he was clearly an abomination. Flipping about the nest, and strangling his siblings, he was aggressive, agile and strong. His mother cast him out, but he survived.
Scavenging and surviving, he lived off the bones of local fauna he stalked and killed, building a small shelter from the tusks of a dead. He capitalized on his species ability of quick thinking and multiple arms to use thrown weapons to take out his prey from range.
As he grew into adulthood, his isolation and self-reliance shaped him into a confused yet powerful hunter.
He found his place among former Alliance crew, holding artillery stations and eventually gaining proficiency with long ranged weapons.
Mostly others recognized his larger muscled limbs, and they never failed to comment. It usually ended in a quadruple punch knockout when they did.
As the Empire faded into memory and Tusker washed through the tides of the uncertain future of the galaxy, he grew fond his unique physique. He was capable and angry. He fell in with bounty hunters for a brief time, and later found himself helming the mounted weapons of their gunships.
One successful mission on the devastated planet of Scarif, he purchased a recovered and refurbished MWC-35c heavy weapon. He named her Shurlee. The tides of the future took him to places he had never expected.
