Haemo (sometimes his name is mistakenly spelled Hano) is a red blood cell that features only in the series Once Upon a Time... Life. Like other red blood cells, he carries oxygen in a pouch on his back.
Haemo is strong and always there to protect his friends, but he is kind and soft at heart. He also often frequently expresses a strong dislike towards carrying carbon dioxide through the veins. He may or may not be based on the archetype Jumbo, who appears both in this series and in all the others.
