Loki is the prince of the kingdom of the giants Elbaf. He once fell in love with Lola and wanted to marry her. Big Mom hoped this would win over the warriors of Elbaf for her pirate gang, but Lola disappeared before the wedding to look for a husband herself. Her twin sister Chiffon was to take her place, however Loki spotted the hoax and was enraged by it. Since then, there has been an even more hostile atmosphere between the giants and Big Mom than before, which is why there are no giants on Whole Cake Island.
- The name Loki comes from Norse mythology and refers to Loki, the god of lies.
