Lord Voldemort physical appearance

Wormatail pulled open the robes on the ground, revealing what was inside them, and Harry let out a yell that was strangled in the wad of material blocking his mouth.
It was as though Wormtail had flipped over a stone, and revealed something ugly, slimy and blind - but worse, a hundred times worse. The thing Wormtail had been carrying had the shape of a crouched human child, except that Harry had never seen anything less like a child. It was hairless and scaly looking, a dark, raw, reddish black. Its arms and legs were thin and feeble, and its face - no child alive ever had a face like that - was flat like that -was flat and snake-like, with gleaming red eyes.

'Bone of the father, unknowingly given, you will renew your son!'
'Flesh - of the servant - w-willingly given - you will - revive - your master.'
'B-blood of the enemy... forcibly taken... you will... resurrect your foe.'
