Game of Thrones: Rexxar, the Half-Blood Beast King

After transmigrating to Westeros, he gets a World of Warcraft Beast Master template, along with a height of 2.4 meters and a weight of 180 kilograms! [Ding! Main quest activated: Tame your first battle pet!] Looking at the Stormlands boar king before him, standing two meters at the shoulder with tusks longer than a man's arm, Rexxar grinned. He didn't dodge or back down. He met it head-on! One punch cracked the boar king's skull. Then, with a flex of both arms, he snapped its tusks clean off! [System notification: Successfully force-tamed the boar king, “Pig”!] [Reward received: “Mend Pet” skill] Brienne, the “beauty” passing by, gaped in astonishment. “Y-you... What kind of knight are you? Could I be your squire?” [Quest: Take on “beauty” Brienne as a disciple. Reward: Arcanite Reaper] Rexxar grinned, his slightly protruding canines showing. His smile was sincere yet savage. “Me? Just a hunter passing through.” “You don't stand a chance of becoming my squire. Be my student instead, and I'll teach you to hunt!” The nobles play politics? The Lannisters have gold mines? The Targaryens have dragons? Sorry, against the brute force of wild beasts, they're all trash! As long as the quests keep paying out, I'll smash the Iron Throne to pieces!
