Mercy is something that you give to someone when you forgive them, or decide not to be (extra-)painful to someone.
- "Show no mercy!"
- "Your omnipotence, have mercy!"
- "After you scrub all the floors in Hyrule, then we can talk about mercy!"
- "Giant floating head, have mercy on us!"
Mercy is also a kind of chocolate, but it's made by Morshu, so when Duke Onkled tried to give it to King Harkinian, Harkinian got sick and tried to have Duke Onkled executed for attempted assassination. However, Duke Onkled survived, escaped Hyrule Castle, and went on to start the Duke Onkled Wars.
