Compound word The ultimate disguise for Superman.

Teeth I defy till key aligns, Guardian of gold, secrets, and shrines. Tumblers dance at turn precise, Burglar's bane, owner's prize. Pick me wrong, I bite with spring, Silent sentinel, everything. What bars the door yet holds no sting?

Paper takes new form, Folded dreams in silent flight, Birdsong in the hand.

Each guest I host kills the one before, My grip is firm but fleeting. A stiff back bears what won't endure My memory keeps deleting.

I drip when you're sad, A twist stops my tears, Hot or cold I provide, In kitchen or bath, I'm revered.
