Zhang Guo Lao and his donkey
One of China's Eight Immortals. According to legend he was an advisor to Emperor Yao, who himself was a legendary emperor that supposedly ruled China nearly four thousand years ago. He appears in Hammered as part of the group trying to kill Thor. He is surprisingly adept at combat (surviving an extended dual with Tyr and coming out of it with only bruises) and favors using iron rods to immobilize targets with pressure point attacks. He is after Thor because the Thunder God tricked him into killing and eating his beloved donkey with the promise of resurrecting it later. Thor left him stranded while laughing, never intending to bring the donkey back.
