Vox's claws
Glorifying another Vox body part - this time: clawsies!
Why do you think he has them? Figuratively "digging his claws" into his followers on Earth? A lot of sinners have claws, so it just might be common demon trait. Nobody mentions Vox's claws at all so they're probably pretty ordinary.
What is their purpose? Looking cool and cute, but also conducting electricity perhaps? We see past Vox do that too.
Are they soft? He can "fold" them in a fist just fine and we see them bend too. Vox touches a lot of people and to our knowledge nobody has complained about being accidentally scratched by him. But at the same time they scratch glass and tables with incredible ease and we hear claw sounds when he taps on the table or claps. He also can tap on his smartphone without damaging it and hold paper without tearing it.
Maybe they're only sharp when he wants them to?
