Artist’s description from tumblr:

-*Tirek*, a massive and wild lion that was captured alongside his brother and sent to the circus. Tirek’s impressive size and power has often led him being thrown into a ring with a variety of different animals, ranging from other captured lions to tigers and even rhinos, all as a way to forcibly show off his tremendous strength as entertainment in the circus. Many of his scars come from this segment in his time at the circus, and with every near-death experience, every feel of the crack of a whip snapping against his skin, his hatred toward humans grew. They stole him and his brother away from their home, their families, used them for their own twisted games, and he has never forgotten or forgiven them for it. Even after being rescued from the circus by the Sisters, Tirek does not care: as far as he’s concerned, they simply traded a small cage for a larger cage. And he wants out.

It doesn’t help that Tirek is beginning to feel betrayed by his own brother, whom he’s been having arguments with and at higher frequencies. He has a plan to escape, and he’ll do whatever it takes to achieve the goal (and kill as many humans as he goes). And as far as he’s concerned, you’re either with him… or against him. And he will force his brother to make his decision soon.
