Actually I've looked a bit more closely at the Killian episode and he's not as completely superhuman as it appears at first sight. He'd apparently dislocated his shoulders umpteen times previously. They'd have been getting increasingly weakened and prone to further dislocations; possibly a good advert for taking more time to rehab fully. Since the Hardrock 100 he's needed reconstructive surgery on both shoulders at a clinic in Barcelona.
So, only 99% God-like...
